Hardware overview
The storage system consists of a controller chassis and one or more drive chassis mounted in a 19-inch rack.
Controller chassis
The controller chassis contains the following components:
- Controller boards (CTLs, also called DKCs.)
- Front-end modules (FEMs), also called channel boards (CHBs)
- Back-end modules (BEMs), also called disk boards (DKBs)
- Power supply (PS)
- Backup fan module (BKMF)
- Accelerator FAN Module (ACFL)
The CTLs contain the cache memory (CM) and cache flash memory (CFM) for the storage system. The VSP E1090 supports 1,024 GiB of cache memory.

Rack support
The storage system can be installed in the Hitachi Universal V3 Rack, Universal V2B Rack, or Universal V2 Rack as well as non-Hitachi 19-inch racks that meet the storage system's specifications.
Non-Hitachi racks must be 4-post, EIA 310-D compliant with adequate airflow and weight capacity. The PDUs must be mounted properly to avoid any issues for servicing the storage system. The PDU receptacles must face toward the back (not toward each other). The area behind the storage system and between the vertical 19-inch mounting posts must be free of PDUs and cable loops.
