Setting Up Your Dell SCv3000 and SCv3020 Storage System (iSCSI Front End) 1 Before You Begin 2 Warning! Before you set up and operate your Dell storage system, review the safety instructions that came with your storage system. Unpack Storage Center Equipment A Dell SCv3000 series 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 Mount the Chassis and Optional Enclosures 3 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. Install the Bezel 1. Hold the bezel with the logo upright. 2. Hook the right end of the bezel into the right side of the chassis. 3. Swing the left end of the bezel toward the left side of the chassis. 4. Press the bezel into place until the release latch closes. 5. Use the key to lock the front bezel. 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 fabrics. 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, NIC or iSCSI 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. 4 Cable the Host Servers to the Storage System Fault domains provide fault tolerance at the storage controller level. 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. iSCSI IO Card Cabling Connect the host servers and storage system to the corresponding Ethernet switches. iSCSI 4 Port Configuration 1. 2. Install the NIC or iSCSI HBAs in the host servers. Connect each host server to both switches. – Connections shown in orange belong to fault domain 1. – Connections shown in blue belong to fault domain 2. 3.

The Ethernet management port provides access to the Storage Center and is used to send emails, alerts, SNMP traps, and support data. 1. Connect the Ethernet management port on the top storage controller to the Ethernet switch. 2. Connect the Ethernet management port on bottom storage controller to the Ethernet switch. Setting Up Your Dell SCv3000 and SCv3020 Storage System (iSCSI Front End) Cable the Backend 6 CAUTION: Make sure that the power switches are in the OFF position before connecting the power cables. To add capacity to your storage system, you can connect up to sixteen SCv300, eight SCv320, or two SCv360 expansion enclosures to an SCv3000 series storage system. A maximum of 222 physical disks are supported in an SCv3000 series storage system. Each expansion enclosure includes two Enclosure Management Modules (EMM) in two interface slots. 1. Connect the power cables to both power supply/cooling fan modules in the storage system chassis. 2. Use the velcro straps to secure the power cables to the storage system chassis. 3. Plug the other end of the power cables into a grounded electrical outlet or a separate power source such as an uninterrupted power supply (UPS) or a power distribution unit (PDU). NOTE: If the storage system is installed without expansion enclosures, do not interconnect the back-end SAS ports on the storage controllers.
