From Wikipedia, the free encyclopedia

Virtual Storage Platform is the brand name for a Hitachi Data Systems line of computer data storage systems for data centers. Model numbers include G200, G400, G600, G800, G1000, G1500 and G5500

History[edit]

Hitachi Virtual Storage Platform, also known as VSP was first introduced in September, 2010.[1] This storage platform builds on the design of Universal Storage Platform V, originally released in 2007.[2]

Architecture[edit]

At the heart of the system is the HiStar E-Network, a network crossbar switch matrix. This storage platform is made up of different technologies than USP and USP V. The connectivity to back-end disks is via 6 Gbit/s SAS links instead of 4 Gbit/s Fibre Channel loop. The internal processors are now Intel multi-core processors, and in addition to 3.5-inch drives support has been added for 2.5 inch small-form factor HDDs. The VSP supports SSD, SAS and SATA drives.[3]

Features included:[4]

  • The ability for growth in three ways:
    • Scale up to meet increasing demands by dynamically adding processors, connectivity and capacity in a single unit. This enables tuning the configuration for optimal performance for both open systems and mainframe environments.
    • Scale out to meet demands by dynamically combining multiple units into a single logical system with shared resources. Support increased needs in virtualized server environments and ensure safe multitenancy and quality of service through partitioning of cache and ports.
    • Scale deep to extend the functions of Hitachi Virtual Storage Platform to multivendor storage through virtualization. Offload less-critical data to external tiers in order to optimize the availability of the tier one resources.
  • Supports automated storage tiering, known as Dynamic Tiering, to automate the movement of data between tiers to optimize performance.
  • Front to back cooling airflow for more efficient cooling
  • Improved capacity per square foot and lower power consumption compared to the USP V.
  • Enables virtualization of external SAN storage from Hitachi and other vendors into one pool
  • Supports online local and distance replication and migration of data nondisruptively internally and between heterogeneous storage, without interrupting application I/O through use of products such as Tiered Storage Manager, ShadowImage, TrueCopy and Universal Replicator.
  • Single image global cache accessible across all virtual storage directors for maximum performance.[5]
  • Automated wide-striping of data, which allows pool balancing and lets volume grow or shrink dynamically.[5]
  • The system can scale between one and six 19-inch rack cabinets. It can hold a maximum of 2,048 SAS high-density 2.5-inch drives for 1.2 petabytes of capacity, or 1,280 3.5-inch SATA drives for a maximum capacity of 2.5 petabytes.[6]
  • Supports thin provisioning and storage reclamation on internal and external virtual storage
  • Provides encryption, WORM and data shredding services, data resilience and business continuity services and content management services.

Storage Management[edit]

Hitachi Command Suite (formerly Hitachi Storage Command Suite) provides integrated storage resource management, tiered storage and business continuity software.[9] Hitachi Command Suite employs a use case-driven, step-by-step wizard-based approach that allows administrators to perform tasks such as new volume provisioning, configuration of external storage, and creation/expansion of storage pools easily on the fly.[10]

Hitachi Command Suite is composed of the following software products:[11]

  • Hitachi Basic Operating System[12]
    • Hitachi Dynamic Provisioning
    • Hitachi Device Manager
    • Hitachi Dynamic Link Manager Advanced
  • Hitachi Basic Operating System V[13]
