VSP G350 and VSP G370 Controllers

The VSP G350 and VSP G370 are equipped with multiple controllers for communicating with a data host.

Each controller includes the following internal components such as a processor, dual in-line cache memory modules (DIMMs), cache flash memory (CFM), battery, and fans. The controller has an Ethernet connection for out-of-band management using Hitachi Device Manager - Storage Navigator. If the data path through one controller fails, all drives remain available to data hosts using a redundant data path through the other controller. The controller is equipped with LED indicators for monitoring its operating conditions and notifying possible component replacement.

Controller chassis with small form-factor drive bays (CBSS)

The CBSS controller chassis houses controllers, backup fan modules, power supplies, and provides twenty-four slots at the front for loading large form-factor (2.5-inch) data drives. The chassis also includes specific functional LEDs located on the front and rear of controller to provide its operating status.

The following table lists the controller board specifications.
