VSP G1000 ARCHITECTURE

                Here I am discussing about major components and architectural differences with VSP as well as features of VSP G1000.

Controller Chassis Components:

Front End Directors (FED/CHA)

Virtual Storage Directors (VSD/MPB)

Cache Path Control Adapter (CPC)

Cache Memory Backup (BKM)

Back-End Directors (BED/DKA)

Service Processor (SVP)

Cooling Fans

AC –DC Power Supply

      All of the Controller boards within a system are connected through the HiStar-E network of Paths.

Major Change in Controller Design is CPC:

Ø  New Cache Path Control Adapter è Combined VSP Cross bar Switch (ESW Switch) and Cache Memory adapter functionality.

Ø  Virtual Storage Director Pairs è  Up to Four per Controller and Eight per Subsystem.

VSP G 1000 Specifications:

Max Cache Size: 2TB

Maximum Internal Disks: 2,304 –2.5 Inch Disks (2.7 PB max)

                                              1,152 – 3.5 Inch Disks (4.5 PB max)

Max VSD Pairs & Cores:  8 VSD Pairs & Total 128 Cores (Processor Type – Xeon E5 (Eight Core))

Max FED Ports: 192 FC

      With VSP G1000 HDS came up with new Operating System i.e. Hitachi Storage Virtualization Operating System (with VSP – BOS/BOS V).
