Hardware overview

 

The storage system consists of a controller chassis using a multi-node architecture that deploys a copper or optical link, as well as the basic rack layouts similar to previous model.

Hardware components

 

The storage system consists of a controller chassis comprising controller boards, drive chassis in which drives are installed, and a node interconnect switch consisting of interconnect switches and an SVP. The storage system also supports cache memory (DIMM) and cache flash memory (CFM).

The controller chassis, drive chassis, and node interconnect switch are installed in a 19-inch Hitachi Universal rack.

Controller chassis

 

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 SVP monitors storage system operations by collecting statistics and reporting this information to the Hitachi Remote Ops monitoring system.

If an optional second SVP is installed, the primary SVP is the active unit while the secondary SVP acts as a hot standby. If the primary SVP fails, the hot standby SVP takes over within three minutes. In this way, the dual-SVP configuration eliminates single points of failure with the SVP.
