Setting Up Your Dell SC5020 Storage System
Warning! Before you set up and operate your Dell storage system, review the safety
instructions that came with your storage system.
Warning! The chassis is heavy. Do not attempt to lift
the chassis without assistance.
Use the racking instructions included with your package to mount the chassis.
Mount the storage system chassis and expansion enclosures in a manner that allows
for expansion in the rack and prevents the rack from becoming top-heavy. Secure the
storage system chassis to the rack using the mounting screws that are located behind
the latches on each chassis ear. Dell recommends mounting the storage system chassis
in the bottom of the rack.
1 2Before You Begin Mount the Chassis and Optional Enclosures
Unpack Storage Center Equipment
A Dell SC5020 storage system includes:
• Documentation
• Storage system
• Front bezel
• Rack rails
• Power cables (2)
• USB cables (2)
Develop a Configuration Plan
Before installing the storage hardware, develop a configuration plan where you can record host
server information, switch information, and network information.
Record System Information
• System management IPv4 address for Storage Center
• IPv4 address of the MGMT port on each storage controller
• Domain name
• DNS server address
• Additional IPv4 addresses if the storage system has iSCSI I/O ports
Consider Plans for Multipath/Failover
Redundancy is provided by fault domains, which allow alternate paths if a path fails. Fault
domains are determined by the number of independent Fibre Channel fabrics or iSCSI networks.
Each switch carries a separate fault domain. If a port fails, any port within the same fault domain
takes over for the failed port. Dell recommends using multipathing, so that volumes are mapped
to ports in more than one fault domain.
More Information
For operating system, host bus adapter (HBA), and switch requirements, refer to the Dell
Storage Compatibility Matrix on the Dell Tech Center at http://en.community.dell.com/
techcenter/storage.
The SC5020 storage system supports Fibre Channel, iSCSI, or SAS protocols to connect the Storage Center to host servers. Fault domains provide fault tolerance at the storage controller level. If you are using Fibre Channel,
incorporate your switch zoning strategy with the fault domains. Dell recommends using redundant cabling to avoid a single point of failure.
1. Identify the protocol being used to connect the host servers to the disk array.
2. Refer to the diagram below that corresponds to the proper protocol. These cabling guidelines ensure the configuration has redundancy and failover capability. For more information, contact Dell Technical Support.
4Prepare the Host Servers 5Cable the Host Servers to the Storage System

Setting Up Your Dell SC5020 Storage System (continued)
To add capacity to your storage system, you can connect up to sixteen SC400 or eight SC420 expansion enclosures to an SC5020 storage system. A maximum of 222 physical disks are supported in an SC5020 storage system.
Each expansion enclosure includes two Enclosure Management Modules (EMM) in two interface slots.
NOTE: If the storage system is installed without expansion enclosures, do not interconnect the back-end SAS ports on the storage controllers.
1. Power on any network switches, routers, or other standalone
components.
2. Power on any expansion enclosures that might be a part of the system.
3. Power on the storage system by turning on both power supply/cooling
fan modules.
The Dell Storage Manager Client provides access to the initial setup wizards. The wizards help you remotely discover and configure storage systems and configure connected
host servers.
NOTE: The initial setup wizards are only supported on 64-bit operating systems.
Install and Start the Dell Storage Manager Client
1. Log in to the Dell Digital Locker at www.dell.com/support/licensing, register your storage
system, and download the Windows or Linux version of the Dell Storage Manager Client.
2. Install the Dell Storage Manager Client on the host server. To discover and configure a
Storage Center, the software must be installed on a host server that is located on the same
subnet as the storage system. For host setup, the client does not have to be on the same
subnet as the storage system.
3. To start the software on a Windows computer, right-click on the Dell Storage Manager
Client shortcut and select Run as administrator.
To start the software on a Linux computer, execute the command ./Client from the
var/lib/dell/bin directory. The Dell Storage Manager Client welcome screen opens.
Discover and Configure Storage Center Wizard
1. Click the Discover and Configure Uninitialized Storage Centers link. The Discover and
Configure Storage Center wizard opens.
2. Follow the steps in the wizard to discover and configure uninitialized Storage Centers.
3. For Fibre Channel installations, the deployment wizard provides the storage controller
WWNs for zoning requirements. When prompted, create the two required zones for each
fault domain.
Configure Host Access to a Storage Center
1. For Windows and Linux servers, click the Configure this host to access a Storage Center
link and log in to the Storage Center.
For VMware ESXi servers, click Configure VMware vSphere to access a Storage Center.
2. Follow the steps in the wizard to configure the host to access the Storage Center and configure best practices for performing I/O.
3. For Fibre Channel, configure zoning to make sure that storage is visible to the host servers. Using the switch software, create a zone for each HBA connected to the
switch. In the zone, include only one HBA WWN and all of the virtual WWNs of the storage controller I/O ports connected to that switch. This is referred to as single
initiator/multiple target zoning. For hosts, you can obtain the WWNs from the operating system or use the switch software.
When the host configuration is complete, use the Dell Storage Manager Client to create and map volumes.
