Site Preparation Guide for VSP G/F350, G/F370, G/F700, G/F900

Part Number

Prepare your site to support the recommended power parameters of your storage system.

Plan to set up redundant power for each rack that contains a Hitachi VSP storage system. Supply the power with a minimum of two separate circuits on the building's electrical system. That way, if one circuit fails, the remaining circuit(s) should be able to handle the full power load of the rack. In addition, each Power Distribution Unit (PDU) within the rack should be powered by a separate power circuit.

Each circuit should be rated appropriately for the storage system model and input voltage. Refer to the storage system's electrical specifications for power requirements specific to each model.

Note: When calculating the power requirements for circuits that supply power to the rack, consider the power requirements for network switches.
