Chapter 2: Storage system hardware overview
The VSP G1x00 and VSP F1500 storage systems can be configured with one or two
controller chassis and up to twelve drive chassis that contain the drives. A controller
chassis contains the control logic, processors, memory, and interfaces to the drive
chassis and the host servers. A drive chassis contains drives, power supplies, and the
interface circuitry that connects it to the controller.
The controller rack contains the controller chassis and up to two drive chassis. Additional
racks can contain an intermix of 16U SFF or LFF drive chassis and/or 8U flash drive
chassis as well as one or two Hitachi NAS (HNAS) file system servers. When the
controllers of a two-controller system are housed in separate racks, the two controller
racks can be placed up to 100 meters apart. In addition, the drive racks attached to a
controller rack can be placed up to 100 meters from the controller rack.
VSP G1x00 support three types of drives: SFF hard disk drives (HDDs) and solid-state
drives (SSDs), LFF HDDs and SSDs, and flash module drives (FMDs), including the second-
generation FMD DC2 drives. The drives are mounted in a chassis that is specific to each
drive type. VSP G1x00 also support a diskless configuration (no drive chassis, all external
storage).
The VSP F1500 all-flash array is equipped with advanced high-density FMDs, providing up
to 4M IOPS and 40 PB of capacity for multi-workload consolidation.
