The controller chassis consists of a controller board, front-end module, back-end module, fabric-acceleration module, power supply, and cache flash memory. Controllers are storage system components that cache and manage data, and provide hosts with a coherent, virtualized view of the system. A controller chassis contains two nodes with a 4U controller each, making the chassis 8U high. A storage system can contain 2 to 6 nodes, depending on the storage system model.

The compression accelerator module, which includes the compression accelerator and a fan, is a hardware component for the VSP 5200 and VSP 5600. The compression accelerator performs compression for these models instead of the storage system controllers, resulting in improved performance for the controllers.
