Setting Up Your Dell SCv3000 and SCv3020 Storage System (Front-End SAS) 1 Before You Begin 2 A Dell SCv3000 series storage system includes: • Documentation • Storage system • Front bezel • Rack rails • Power cables (2) • USB cables (2) Use the racking instructions included with your package to mount the chassis. 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 • • • • 3 Warning! The chassis is heavy. Do not attempt to lift the chassis without assistance. 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 Mount the Chassis and Optional Enclosures System management IPv4 address for Storage Center IPv4 address of the MGMT port on each storage controller Domain name DNS server address 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. 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. 4 Cable the Host Servers to the Storage System 5 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 for cabling guidelines that ensure the configuration has redundancy and failover capability.
