Hitachi Data Systems (HDS) has revamped it biggest storage system and is now shipping a new flagship product the Hitachi Virtual Storage Platform (VSP). HP is also shipping its own branded version of the VSP. Both systems are based on platforms from OEM partner Hitachi Ltd. (NYSE: HIT), and include automated storage tiering. Sister site InfoStor has the story.
In introducing its Virtual Storage Platform (VSP), the successor to its Universal Storage Platform (USP) V, HDS put the emphasis on 3D scaling, which refers to the ability to scale up (performance, capacity and connectivity), scale out (multiple systems in a single logical system) and scale deep (via virtualization of heterogeneous resources).
HDS officials also emphasized the systems page-level Dynamic Tiering, where a page is now defined as a more granular 42MB stripe size. Data can be automatically placed on tier 0 (SSD flash drives), tier 1 (SAS drives) or tier 2 (SATA) according to user-defined policies and the frequency of data access. All of the drive types come in a 2.5-inch form factor, which provides power and cooling advantages vs. older arrays with 3.5-inch drives.
Hitachi Dynamic Provisioning (HDP), or thin provisioning, is also now based on 42MB page sizes and a data dispersion methodology.
The VSP can be configured in a midrange rack with eight processor cores, 16 8Gbps Fibre Channel host ports and 64GB of global cache, and can be scaled up to 128 processor cores, 192 Fibre Channel ports, 1,024GB of global cache, and 2,048 6Gbps SAS drives. HDS VSP supports all data types (e.g., block, file and content).
HP (NYSE: HPQ) introduced the StorageWorks P9500 array today, which is based on essentially the same Hitachi Ltd. platform as HDS VSP. HPs nomenclature may cause some initial confusion because the P9500 is the highest-end member of what has been traditionally referred to as the XP Series of arrays.
