Overview 5

Overview

Overview

The MCS-200/100 is a supplemental cooling system for data centers. It is offered in four configurations:

• MCS-100 unit (single-rack configuration)

Overview 6

• MCS-100 unit (dual-rack configuration)

Overview 7

• MCS-200 unit (single-rack configuration)

Overview 8

• MCS-200 unit (dual-rack configuration)

For successful site preparation, consider the following information:

• To provide dedicated cooling for servers and other IT equipment, the MCS-200/100 integrates with the

facility chilled water plant or a dedicated chilled water loop. HP recommends that you install a

dedicated cooling loop to the MCS-200/100.

• The system provides cooling, recirculation, and condensation management, and it requires a small

amount of AC electric power.

• Internal monitoring and control sensors assure server inlet air set points to be achieved and provide

constant performance feedback through local and network interfaces.

Product overview

The MCS-200/100 is a modular, distributed cooling solution that removes the high levels of heat generated

by current advanced server and mass storage systems. The MCS-200/100 provides a uniform, effective,

affordable, and distributed cooling approach for servers and other IT equipment installed in server racks. The

MCS-200/100 is a closed-loop cooling system integrated as part of a non-ventilated server enclosure, in

contrast to a conventional ”open” server enclosure with perforated front and rear doors.

Overview 12

Air flow for MCS-200 (dual-rack configuration)

The special horizontal airflow of the MCS-200/100 fully supports the industry standard front-to-back cooling

principle, such as cold air drawing into the front of the server and warm air being expelled out the rear of the

unit. All devices receive adequate and evenly distributed cool air regardless of the mounting position within

the enclosure. The MCS-200/100 distributes precisely cooled and targeted air flow evenly across the front

of the IT equipment. Warmed air is then channeled from the rear of the IT equipment into the side-mounted

or center-mounted MCS-200/100 cooling unit. From there it is cooled and recirculated to the front of the

equipment stack.

Key components

The MCS-200/100 uses the following key components to provide cooling performance. Some of these

components are optional for MCS-100. For more information, see "MCS-100 components (on page 13)."

• Main breakers—Provide power for the MCS-200/100 through circuit breakers. They do not control

power at the input panel.

If the MCS-200/100 is still connected to a power source, voltage is applied before the circuit breakers

at the input panel

• Heat Exchanger Module (HEX)—Uses an air-to-water heat transfer device specially created for

demanding data center environments

• Display—Provides general cooling unit status

• Management module—Provides users with web-based capabilities to set, monitor, and control

temperature within the modular cooling unit, and displays the health of the unit

Overview 13

• Fan controller—Operates the fans, according to the cabinet air temperature

• Air bleeder valve—Enables air to manually bleed out of the system when coolant is initially filled

• Water controller—Senses condensation, leaks, water temperatures, flow rate, and the status of the

water valve, and sends this data to the management module

• AC input/network connection—Provides primary and secondary AC input connections, if available,

and a network management interface

• AC transfer switch—Provides dual-AC power with a fail-over feature for redundancy

• Fans—Provide circulation of cooled air through the computer equipment rack

• Water group—Includes the water valve, flow meter, check valve, and temperature sensors

A condensation pump with overflow and condensation lines connects to the water group.

Each MCS-200/100 has one water group.

MCS-100 components

The MCS-100 is an air and water heat exchanger that removes high levels of excess heat generated by

equipment installed in HP racks. The installed equipment pulls cold air in through the front of the closed

MCS-100 and uses that air for internal cooling. After the air is warmed, the MCS-100 expels the air through

the rear vents.

Facility planning for implementation

Facility planning overview

The MCS-200/100 offers an incremental data center cooling solution, capable of cooling 30 kW of heat

with the MCS-100 unit or 50 kW of heat with the MCS-200 unit.

In planning water supply and design, take into consideration short and long-term needs for cooling.

Immediate supply needs must meet the specifications and target cooling requirements, based on the

parameters defined in this site preparation guide. In anticipation of future heat loads, design and install

dedicated loop chilled water piping, based on specific cooling load increments (such as 50 kW or 250 kW),

the specific number of MCS-200/100 per row or loop, and other site build-out planning parameters. As

cooling, rack space, and equipment density requirements increase, you can add MCS-200/100 units to the

chilled water system.

To route water lines to your MCS-200/100 unit, use one of the following methods:

• Through an opening in the raised floor

• Lying on top of the floor (for MCS-200 only)

• Through the top of the MCS-200/100 unit

For more information on routing the water lines, see the Hook Up Kit installation instructions in the HP

Modular Cooling System 200/100 Options Installation Guide.

Installation service for the MCS-200/100 is order number UE005E.

For site evaluations and technical consulting for your site, see the HP Services website

(http://www.hp.com/services/criticalfacilities).

The implementation of the MCS-200/100 aligns with Data Center Best Practices. For more information, see

Optimizing Data Centers for High-Density Computing, which can be found on the HP website

(http://h18004.www1.hp.com/products/servers/proliantstorage/racks/10000series/documentation.ht

ml).

This section discusses key issues for site preparedness, including:

• Space considerations for delivery, operation, and service, and other space-related considerations such

as floor loading

• Electrical considerations

• Coolant source options and quality considerations

• Other considerations

A complete site preparation checklist is provided in Appendix A: Forms and checklists (on page 81).

Space and positioning considerations

When fully populated, the MCS-200/100 unit is larger and heavier than a standard 482.6 mm (19-inch)

equipment rack. Therefore, more space is required to maneuver, operate, and service the MCS-200/100.

Facility planning for implementation 21

Delivery space requirements

Be sure your facility has adequate space to receive and remove the MCS-200/100 from the shipping pallet.

Consider the following when unloading the racks:

• Forklifts must enter and transport the shipping pallet from the side.

• Delivery plans must include the possible removal of walls or doors.

Maneuvering space requirements

WARNING: To reduce the risk of personal injury or damage to the equipment, do not attempt to

move equipment racks alone. Obtain adequate assistance to stabilize the rack during movement,

or hire professional equipment riggers.

WARNING: To reduce the risk of personal injury or damage to the equipment, use extreme care

when moving racks with casters. Sudden stops, excessive force, and uneven surfaces can cause

the product to overturn.

When maneuvering the MCS-200/100, use the following guidelines:

• Move racks that have casters with care. Sudden stops, excessive force, and uneven surfaces might

cause the product to overturn.

• Due to stability and safety concerns, the cooling unit and IT rack have casters that are fixed to the front

and swivel in the back. For more ease, move the MCS-200/100 with the back as the leading edge.

• For long and straight distances, roll the MCS-200/100 with the front fixed casters leading. For better

mobility, lead with the rear swiveling casters.

• When rolling the MCS-200/100, push firmly on the front doors frame and not the door mesh of the IT

rack. The points where you should push theMCS-200/100 are marked by the factory.

• Be sure that the rooms and doors are large enough to accommodate the movement of the

MCS-200/100 cabinet into the data center.

• When transporting the MCS-200/100 to a different building floor, ensure the elevators have adequate

load capacity, floor space, and door clearance to accommodate the rack. The MCS-200/100 pallet

can only be moved with forklifts from the side, which has a length of 1829mm (72 inches).

• When transporting the MCS-200/100 within a building, ensure that doorway thresholds are adequate

to hold the rack. HP does not recommend that you lift or transport the MCS-200/100 by eyebolts that

are attached to the upper corners of the cabinet.

The following figure shows the maneuvering space required when unloading the MCS-100 and MCS-200

from a pallet. When planning to maneuver the unit, use the delivery forms provided in "Appendix A: Forms

and checklists (on page 81)."

Facility planning for implementation 22

CAUTION: HP recommends that a ramp angle of no greater than 5° be used to move the

MCS-200/100 up or down elevations. Typical data center ramps have a 5º angle (1 to 12

pitches).

Operational space requirements

To provide space for internal airflow and housing of the cooling unit components, the MCS-200/100 is

wider and deeper than conventional HP racks.

HP recommends the minimum access space for the MCS-200/100 be 1219 mm (4 ft) in the front and 914

mm (3 ft) in the rear, as shown in the following figures.

• With the top shipping bracket, the total height is 2069 mm (81.5 inches).

• The MCS-200/100 unit requires approximately 600 mm of additional width (space) to accommodate

the second IT rack, which is mounted to the left of the cooling unit.

System positioning

The MCS-200/100 can be installed next to an existing or new row of HP Intelligent Series racks. Based on

facility design requirements, the cabinets can be arranged in a flush front or flush rear configuration.

Facility planning for implementation 26

Flush front configuration examples

When arranging the MCS-100 or MCS-200/100 next to an HP Intelligent Series rack, and depending on the

configuration, be aware of the potential for slight rear door swing interference. Equipment might require the

removal of a door during installation to allow for unimpeded access.

Cable openings

The MCS-100 and MCS-200 units have several useable cable openings at front top, rear bottom and rear

top of the IT rack.

Cabinet leveling feet

Facility planning for implementation 30

WARNING: Static loading limits cannot be achieved if the rack is not on its leveling feet or is

rolled or pushed from its position. Your floor weight capacity might not support the full static load

capacity. Check with your floor provider before loading. HP is not responsible for floor damages

due to floor overloading.

CAUTION: To reduce the risk of damage to the casters, make sure that the full weight of the rack

rests on the leveling feet and feet pads, and not on the casters. The casters are designed only as

an aid in moving the rack into position. They are not designed to support the weight of the rack,

and the casters may become damaged if relied on to support the rack.

The MCS-200/100 includes leveling feet and does not require fastening to the floor. Care should be taken

during the loading of the equipment to ensure the rack remains stable during operation and servicing to

avoid personnel and equipment damage. MCS-200/100 both support approximately up to 1361 kg (3000

lb) of static equipment load on the leveling feet and feet pads.

The following figures show the locations of the cabinet leveling feet. Be sure there is adequate floor and

remaining understructure support to handle the load-bearing leveling feet, especially immediately around the

cutout. After the MCS-200/100 is positioned in the proper location in the data center, it can be lowered into

place with the leveling feet and leveling feet pads.

The leveling feet pads help to ensure weight distribution and help transfer the load to the support structure

below the floor. You must ensure proper orientation of the feet pads so that subsequent racks can be properly

accommodated.

Floor loading considerations

The computer room floor must be able to support the total weight of the installed server trays as well as the

weight of the MCS-200/100 as they are moved into position. This section contains information about raised

floor installations. HP cannot assume responsibility for determining the suitability of a particular raised floor

system. The customer or local agencies should determine installation requirements. An appropriate structural

engineer should verify any floor system under consideration for a server installation.

Raised floor loading is a function of the manufacturer’s load specification and the positioning of the

equipment relative to the raised floor grid. HP recommends the following guidelines:

• Some raised floor systems do not have grid stringers between floor stands. The lateral support for the

floor stands depends on adjacent panels being in place. To avoid compromising this type of floor

system when gaining under-floor access, remove only one floor panel at a time.

• Larger floor grids (bigger panels) are generally rated for lighter loads.

• MCS-200/100 both support approximately up to 1361 kg (3000 lb) of static loads of equipment on

the leveling feet and feet pads.

Electrical considerations

The electrical practices and suggestions in this guide are based on North American practices. For regions

and areas outside North America, local electrical codes take precedence. An example would be the

recommendation that the protective ground conductor should be green with yellow stripes—this requirement

is a North American directive and does not override the local code requirements for a region or areas

outside North America.

WARNING: To avoid personal injury and damage to the equipment, be sure that an emergency

power shut off switch is in place and is easily accessible.

Facility planning for implementation 41

The MCS-200 provides two Walther Procon A5 series AC input connections and ships with one set of two

power cords for connecting to redundant AC power busses, when available. Only one power cord is

necessary for operation. The second cord can be connected to a redundant AC power bus to improve system

availability by protecting against power source failures or accidentally tripped circuit breakers.

These redundant connections and cords are optional for the MCS-100.

For more information, see "Connecting to facility A/C power (on page 43)."

System grounding

HP server systems require two methods of grounding: power distribution grounding for safety, and

high-frequency signal grounding for equipment performance. Power distribution grounding involves the main

building electrical service entrance, electrical conduit, facility power panels, and equipment cabinets

(including the MCS-200/100 and server cabinets), which should be grounded using green or yellow

insulated wire conductors according to the applicable electrical codes. High-frequency grounding consists of

using ground return conductors for intra- and inter-cabinet signal interconnects as well as chassis and cabinet

grounding.

For MCS-200/100 and server systems installed on a raised floor, the floor assembly should be electrically

grounded to form a complete ground grid. An optimum raised-floor grounding solution is shown in the

following figure.

Each floor panel should have at least one supporting pedestal grounded to the power panel and another

pedestal grounded to an equipment cabinet. This broadband solution provides excellent grounding for

improved safety and performance.

Voltage fluctuations and outages

The MCS-200/100 is designed to provide immunity to power outages of less than one cycle. However,

testing cannot conclusively rule out loss of service. To obtain the best possible performance of power

distribution systems for HP equipment, observe the following guidelines:

• Dedicated power source—Isolates the power distribution system from other circuits in the facility

• Missing-phase and low-voltage detectors—Automatically shuts down equipment when a severe power

disruption occurs. For peripheral equipment, these devices are recommended but optional.

• Online UPS—Maintains constant input voltage for devices and should be considered if outages of

one-half cycle or more are common. For each situation, consult a qualified contractor or consultant.

You can protect the MCS-200/100 from the sources of many electrical disturbances by using:

• An isolated power distribution system

• Power conditioning equipment

• Over- and under-voltage detection and protection circuits

• Protection to reduce high-frequency electrical energy radiation

• Surge protective devices on power cables to protect equipment against electrical storms

Electrical planning around water-handling components

CAUTION: In case water is in contact with the power cables, shut down the main breaker before

cleaning up water in this area.

Because of potential condensation on non-insulated water connections or leaking water connections around

water-based cooling systems, consider the following during the electrical planning:

• Waterproofed connectors

• Watertight conduits for cables

• Leak detection systems

To identify waterproofed connectors, HP recommends that you use the IP rating of the connector based on the

international standard IEC 60529. HP recommends a connector that is rated at least IP 67.

Cable conduits are available in different styles, depending on flexibility and materials. The most common

materials are plastic, metal, nylon, or a composition of these materials. Watertight conduits are available in

both flexible and hard material, depending on the application.

A leak detection system for a data center usually uses leak sensor cables, which are installed on the subfloor

in a raised floor and connected to a facility management system.

Connecting to facility A/C power

The MCS-200/100 accepts AC power through two Walther Procon A5 series power receptacles located at

the top rear patch panel. If available, the MCS-200 ships with one of each AC power cord set for connecting

to redundant AC power busses. The NEMA L6-20 power cord uses a NEMA L6-20 male plug for connecting

to a facility AC feed connector common to North America and Japan. The IEC 309 power cord uses an IEC

309 male plug for connecting to a facility AC feed connector common in various international regions.

These redundant connections and cords are optional for the MCS-100.

Facility planning for implementation 44

MCS-200/100 power L6-20 connector

MCS-200/100 IEC 309 power connector

At least one power cord must be used for MCS-200/100 operation. To improve system availability, the

second cord can connect to a redundant AC power bus (optional for the MCS-100). When the redundant

power is connected, the transfer switch assembly of the MCS-200/100 provides switch-over to the active

power bus, in the event of power source failures or accidentally tripped circuit breakers.

The power cords of the MCS-200/100 are 4 m (13.1 ft) long. The power connections are inside of the top

of the IT rack as shown in the following figures.

Facility planning for implementation 45

When using only a single, primary source for power, the AC power cord is connected to the left-most

receptacle.

When redundant AC power is available, the redundant AC power cord is connected to the right receptacle.

Coolant source planning

CAUTION: The minerals and chemicals typically found in tap water can react with metallic

elements used in the HP Modular Cooling System 200/100 closed-loop distribution system.

Electrochemical reactions can cause scaling, corrosion, leaks, and blockage, ultimately resulting

in reduced efficiency of the cooling system and even damage.

A number of factors relating to a facility water distribution system must be considered during the site

preparation process, including the following:

• Redundant water configurations. For more information, see Appendix B: Conversion factors and

formulas (on page 85).

Facility planning for implementation 46

• The water source should be shared water or dedicated facility water loop.

• Maximum and minimum temperatures of building chilled water plant, and target chilled water

temperature of dedicated loop, should be based on the total cooling capacity required and planned.

• The viscosity of the chilled liquid, combined with the length and elevation changes in piping determined

by selected route, can affect pipe size selection.

For the MCS-200/100, HP recommends using a water source that is a dedicated chiller unit or

water-to-water heat exchanger that enables line isolation, better control of individual systems, and regulated

water quality. The chilled water source for this loop is provided by one or more chiller systems. Advantages

of using a dedicated loop include the following:

• Easier scheduling of maintenance to either a building system or dedicated MCS-200/100 loop

• Easier maintenance of water quality parameters in the dedicated closed loop

• Better temperature and flow regulation to guarantee the needs of the MCS-200/100

• More flexibility to regulate water temperature in order to reduce the potential for condensation

The use of building-chilled water for the MCS-200/100 unit is possible under certain conditions. Consult with

a qualified facilities design expert, however, to determine whether this approach is possible within your

specific data center. Refer to the requirements for water quality, temperature, and flow rate described in this

section. Regardless of chilled water service approach, consult with a qualified facilities design expert to

analyze new and existing systems and specify new work to be sure that water quality, temperature, and

water flow requirements can be met. The new work must meet all local safety and building code requirements

as well as your facility quality standards. Piping drawings and schematics included here are diagrammatic

to convey a conceptual understanding of the MCS-200/100 connection requirements.

Dedicated chiller unit directly supplying the MCS-200/100

Plumbing considerations

When installing the MCS-200/100, consider the following plumbing factors:

• Installing water shut off valves to enable infrastructure system flushing for the inlet and outlet of each

MCS-200/100 (highly recommended by HP)

Facility planning for implementation 47

• Flow rate and pressure capacity of chilled water plant input to the design of the facility feed line and

dedicated water loop pipe diameters

• Material compatibility within piping system to minimize the potential for electrochemical corrosion, and

must be corrosion-resistant

• Minimization of elbows and other restrictions that increase flow resistance

• Insulation of piping to minimize risk of condensation and reduce incidental heating of supplied chilled

water

• Availability of a floor drain or reclamation system to capture system condensation

• Structural securing of piping to support weight of distribution network filled with water

• Water quality management, including particulate filtration, treatment, and flushing provisions, with

isolation valves for service requirements

• Availability and access to a data center leak detection system to monitor the infrastructure system for

leaks

• Air vents installed at the highest point in the pipe system

Each MCS-200/100 has an air vent, but additional vents in the supply piping system must be

considered.

HP Water Hook-Up Kit

HP recommends using the MCS-200/100 Water Hook-up Option Kit BW971A, available on the HP website

(http://www.hp.com), to connect the MCS-200/100 to a facility chilled water system. Each kit includes the

hoses and accessories required for connecting the facility supply and return lines to the main inlet and outlet

connections of an MCS-200/100 unit and must be installed prior to the delivery of an MCS-200/100.

CAUTION: You must properly connect the cabinet and facility cool water inlet and warm water

outlet hoses. The MCS-200/100 does include a check valve to prevent the reverse flow of

coolant.

The MCS-200/100 has the connecting fittings inside the unit, approximately 600 mm (24 in) above the floor

on the rear side. It allows the main coolant hoses to be routed either down through the cutouts in a raised

floor, as per HP recommendation. The main coolant hoses can also be routed up through openings in the top

of the cabinet and above the unit, or through the back of the cabinet and above the floor (for MCS-200 only).

The left (blue) hose designates the chilled water supplied to the MCS-100 and the right (red) hose designates

the warm water exiting from the MCS-200/100.

• Through raised floor cutouts

Facility planning for implementation 49

• Above the floor (for MCS-200 only)

Facility planning for implementation 50

• Above the unit

An HP Water Hook Up Kit must be installed prior to activating an MCS-200/100. The kit contains

approximately 350 cm (138 inches) of flexible hose with terminated fittings on each end. The length that is

available outside the MCS-200/100 depends on the preferred type of connection.

The following figure shows the location of the condensate and overflow in the rear of the cooling unit. The

MCS-200/100 includes both tubes for the hookup. Each tube is approximately 3 m (9 ft) in length. The

overflow hose has an inner diameter of 9 mm (0.35 inch) and the condensation hose has an outer diameter

Facility planning for implementation 51

of 8 mm (0.31 inch). The preferred method of routing for all hoses is downward at an angle of at least 3º

(pitch of 0.6 inch per 12 inches), without loops, and away from the MCS-200/100 cabinet. For MCS-200

only, pumped condensation and gravity-fed overflow hoses must be routed to a floor drain or reclaim system.

Flexible attachment hoses are intended to allow for deflection in any direction for equipment mounted on

dynamic platforms, or for slight relocation of cabinets. Installation service for this MCS-200/100 is order

number UE005E.

Piping approaches

HP recommends the following methods for facility plumbing orientation of the MCS-200/100:

• Direct rear approach

• Left rear approach

• Right rear approach

You can approach the MCS-200/100 from the front with piping for the top and bottom connection. This

approach, however, requires careful planning for accessible component locations and hose attachments.

Facility planning for implementation 52

The following figure shows the recommended facility piping approaches to the MCS-200/100.

Item Description

1 Preferred piping location: locate chilled water piping taps

behind the MCS-200/100—either under or above the

floor. Chilled water taps must approach laterally.

2 Do not locate piping connections or components under the

MCS-200/100.

3 Alternate piping location: locating chilled water piping

taps in front of the MCS-200/100. Under the floor is

possible. This option requires careful planning due to the

chilled water hose length limitation.

Raised floor cutouts for the MCS unit

A complete MCS-200/100 installation typically requires the following floor cutouts in a raised-floor facility

(standard rack configuration):

• One floor cutout for the chilled water hoses and drain hoses of the cooling unit

• One floor cutout for the power cords and data cables of the computer equipment rack, including power

supply to the MCS-200/100. For more information on the top openings, see "Cable openings (on page

26)."

Raised floor panels vary in size globally but create virtual grid lines or seams where panels come together.

These seams are ideal for positioning computer racks on the raised floor. The following figures reference the

locations of rack attributes aligned with raised floor seams to provide critical dimensions for floor cutouts.

A wider opening in the back of the IT rack is optional with MCS-200. The floor tile sizes used in the above

options are 600 mm x 600 mm (23.6 inches x 23.6 inches). Floor tile sizes vary. The allowable tolerances

are +/- 3.2 mm (+/- 0.125 inch). When installing multiple MCS-200/100 units in a row, you must consider

the tolerances as you plan the cutouts.

Chilled water system components

Chilled water supply and return service are required for each MCS-200/100 in order to have a particular

combination of components for peak performance. These components are identified in the following figures

and tables. Components drawn with a solid line are strongly recommended. Components drawn with dotted

lines are advisable for a higher availability and serviceability.

Typical plumbing installation guidelines

CAUTION: The water supply system feeding the HP Modular Cooling System 200/100 must be

capable of withstanding operation with rapid and frequent changes in flow requirements.

• Installation service for this MCS-200/100 is order number UE005E.

• Contractors must install all valves, strainers, and other piping components to the specifications provided

in “Piping approaches (on page 51).” All components must be readily accessible.

• Contractor must flush all lines of debris and cap prior to MCS-200/100 installation.

• Contractors must furnish and install Armacell AP/Armaflex closed-cell elastomeric thermal insulation

with minimum 25-mm (1-inch) wall thickness on all customer piping and fittings. Contractors shall furnish

and install similar insulation type with minimum 6.4-mm (0.25-inch) wall thickness for MCS-200/100

chilled water hoses and fittings. The MCS-200/100 hoses have a 45-mm (1.75-inch) OD and a bolt

clamp that is 76 mm (3 inches) wide, 57 mm (2.25 inches) high, and 51 mm (2 inches) deep on the side

that must be connected to the infrastructure pipe. All insulation joints must be taped with AP/Armaflex®

Insulation Tape, 3 mm (0.125 inch) thick x 50 mm (2 inches) wide x 9.1 m (30 ft) long. Mitered fittings

must be cemented with Armaflex® 520 Adhesive.

• MCS-200/100 condensate and overflow hoses do not require insulation.

• Filters might require a minimum of a 762-mm (30-inches) clearance under the floor for installation. If the

filters cannot be installed under the floor due to space constraints, they can be placed upstream of the

piping system.

HP recommends that the MCS-200/100 Hook Up Kit (BW971A) be ordered for each MCS-200/100

installed.

The water supply system feeding the MCS-200/100 must capable of withstanding the following situations:

Cooling loop sizing

Sizing the cooling loops can be straight forward based on the planned cooling requirements of each

populated/planned MCS-200/100 server enclosure. The amount of heat, in watts, that needs to be removed

from each component in the server rack must be added together to obtain the total heat to be removed by the

MCS-200/100 cabinet. You can copy the following table for documenting individual cabinet calculations.

Calculations must include the equipment installed today and additional equipment planned for installation

Total for Cabinet*

*An approximate value can be estimated by assuming all power entering the cabinet is converted to heat.

After calculating the total expected required heat load, use the charts in “Determining heat load capacities

(on page 72)” to determine required water flow and pressure based on potential chilled water temperatures.

The PSID must be measured prior to the cold water inlet/after warm water outlet. All water system equipment,

materials, and installation must comply with any applicable construction codes and LAHJ.

Determining heat load capacities

The total airflow required by the equipment installed in each server rack must be compared with the total

available supply from the MCS-200/100, so it is not exceeded. The fans in the MCS-200/100 are

speed-controlled to reduce the airflow in case the maximum cooling capacity is not demanded from the

MCS-200/100.

Cooling performance is rated at 43 ˚F EWT. MCS with Expansion Rack capacity/airflow is pooled and does

not have to be evenly split between racks. For example, the HP Modular Cooling System 200/100 with 3

fans, provides at total of 2,800 CFM. One rack can use 2,000 CFM and the other can use 800 CFM.

A minimum heat load is necessary for operating the MCS-200/100 properly. This minimum depends on the

water supply temperature as shown in the following table.

Facility planning for implementation 74

When the minimum heat load is not provided to the MCS-200/100, unstable control of the temperatures and

flow rates of the MCS-200/100 can occur.

For more information, contact your HP representative.

The following charts offer a guideline for determining the approximate amount of heat that can be removed

from MCS-200/100 based on 20°C (68°F) and 25°C (77°F) server intake air temperatures (in degrees,

Celsius), flow rates as liters per minute (lpm), or in US gallons per minute (gpm), delivered to the unit.

The term “water” in the following charts refers to the coolant described in “Acceptable water quality

specifications (on page 78).”

The following pressure-drop chart is provided as a reference to indicate water flow versus water pressure, for

a fully-opened MCS-200/100 water control valve.

Facility planning for implementation 77

Flow rate versus delta pressure (water control valve fully open)—MCS-100

Flow rate versus delta pressure (water control valve fully open)—MCS-200

A minimum water pressure difference of 1.0 to 1.5 bar (15 to 20 psi) between facility supply and return is

required. The previous figures give the pressure difference with a fully opened control valve. In operation, the

control valve maintains the water flow to the MCS-200/100 by introducing pressure resistance to reduce

the flow to accommodate different water temperatures and cooling capacity. Therefore, the pressure loss in

operation appears higher than shown in the above figures. However, to have the full scale of water flow

Facility planning for implementation 78

available, the provided system pressure difference must be slightly higher than the maximum pressure loss

with a fully opened control valve.

Acceptable water quality specifications

Closed-loop water must not contain any lime scale deposits or loose debris. The water must have a low level

of hardness, particularly a low level of carbon hardness. Filters must be used to remove free floating

particulates and regularly maintained. The water must not be so soft that it corrodes the materials that it

comes into contact. You must periodically add new fresh water, and remove some of the enriched water. HP

recommends a #30 mesh filter for filtering water fed to the MCS-200/100 and a 1 µm filter for prolonged

performance.

The following values are water quality ranges required for continuous quality of performance.

CAUTION: Contaminated water might cause decreased cooling capacity or disruption in

service. The water flowing into the MCS-200/100 unit must meet the guidelines stated in the HP

Modular Cooling System 200/100 Site Preparation Guide. Damage caused by contaminated

water is not covered by the MCS unit warranty.

If your water is out of range, consult a water quality expert.

HP recommends using particulate filtration on the dedicated water supply system connected to the

MCS-200/100 unit.

Additional water precautions

The following actions should be taken during the installation of the MCS-200/100:

• Be sure all foreign matter and particulates are flushed from the system prior to installing the water kits

for the MCS-200/100.

• Evaluate the short- and long-term system requirements against available water capacity.

• Be sure your facility water loop is properly designed for liquid cooling systems and separate from the

sanitary water systems within your building—for example, bathroom, sink, or drinking water.

Facility planning for implementation 79

• Be sure facility managers understand that additional load is being added to the facility water supply. Be

aware that the heat load being added might have an effect on other components being cooled by the

facility water plant.

CAUTION: The water supply system feeding the MCS-200/100 must be capable of withstanding

deadheading (operating with a closed line) and operation with rapid and frequent changes in

flow requirements, including long periods with zero water flow.

Plumbing materials to avoid

Do not use the following materials with a closed water system:

• Oxidizing biocides

• High zinc and brass components

• Non-stainless steel iron components

Control system

The MCS-200/100 includes a control system that constantly monitors the air temperatures, water

temperatures, and flow rate. The management module attempts to maintain the air temperature at the target

set point. If the set point temperature cannot be maintained, the HP Modular Cooling System 200/100

management module will generate an alarm and notify facility management systems, as configured.

For site evaluations and technical consulting services for your site, see the HP Modular Cooling System

200/100 User Guide.

Before installing and running active components

CAUTION: If the MCS-200/100 unit runs in manual mode for a period of time without an

adequate heat load being generated by servers or other computing/networking devices, excess

condensation could occur within the cabinet or system.

Prior to starting up any active components mounted in the MCS-200/100 rack, such as servers, storage

devices, and so on, the following actions must be performed:

Facility planning for implementation 80

• Be sure the chilled water source is on and flowing prior to the start-up of an MCS-200/100.

• Be sure the MCS-200/100 is operational and running before turning on the servers and closing the

front and rear cabinet doors.

Regulatory requirements for EXIT signs

Manufacturers of tritium EXIT signs are “specific licensees,” meaning they are licensed by the NRC or an

Agreement State. The signs are considered “generally licensed devices,” because they are inherently safe

enough to be handled or used by anyone with no radiation training or experience. Although purchasers –

known as “general licensees” – do not need authorization from the NRC or a state regulatory agency to

possess the signs, they are subject to certain regulatory requirements regarding handling, transfer or disposal

of the signs. For more information, see the NRC website

(http://www.nrc.gov/reading-rm/doc-collections/fact-sheets/fs-tritium.html#_edn2). They are also subject

to NRC or Agreement State inspection and enforcement action (including fines) for violating those

requirements. Manufacturers must inform purchasers of the EXIT signs of the regulatory requirements for

generally licensed devices. The general licensee is required to designate an individual responsible for

complying with the regulatory requirements.

Regulatory information 87

Under NRC regulations, a general licensee using tritium EXIT signs:

• must NOT remove the labeling or radioactive symbol, or abandon a sign;

• must properly dispose of an unused sign (see below);

• must report to the NRC or the appropriate Agreement State any lost, stolen or broken signs;

• must inform the NRC or an Agreement State of a name change, change of address or replacement of

a general licensee’s designated representative;

• must NOT give away or sell the sign to another individual, company or institution unless the device is

to remain in use at its original intended location; in such a case, the transferor is to notify the recipient

of the regulatory requirements and must notify the NRC or Agreement State of the transfer within 30

days.

Tritium EXIT signs must NOT be disposed of as normal trash. To dispose of a sign properly, a general licensee

must transfer the sign to a specific licensee. This would typically be a manufacturer, distributor, licensed

radioactive waste broker, or a licensed low-level radioactive waste disposal facility. These facilities may

charge a fee for this service.

Within 30 days of disposing of a sign, the general licensee is required to file a report to the NRC or

Agreement State that includes:

• the device manufacturer’s (or distributor’s) name, model number and serial number;

• the name, address, and license number of the person receiving the device; and

• the date of the transfer.

Reports should be sent to Director, Office of Federal and State Materials and Environmental Management

Programs, ATTN: GLTS, U.S. Nuclear Regulatory Commission, Washington, D.C. 20555-0001.

For more information, see the Fact Sheet on Tritium EXIT Signs on the NRC website
