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, and G1500.
History
Hitachi Virtual Storage Platform, also known as VSP was first introduced in September, 2010. This storage platform builds on the design of Universal Storage Platform V, originally released in 2007.
Architecture
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 6Gbit/s SAS links instead of 4Gbit/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. Features included:
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.
Automated wide-striping of data, which allows pool balancing and lets volume grow or shrink dynamically.
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.
Supports thin provisioning and storage reclamation on internal and external virtual storage
Hitachi Command Suite delivers management along three dimensions in support of the system as it does for all of the company's systems. 3D management simplifies operations and lowers costs along three distinct dimensions:
Manage up to scale with the largest infrastructure deployments
Manage out with breadth to manage storage, servers and the IT infrastructure
Manage deep with the integration required to manage the multivendor resources of today’s complex data centers
Command Suite provides integrated storage resource management, tiered storage and business continuity software solutions allowing customers to align their storage with application requirements based upon metrics including Quality-of-Service, Service Level Objectives, Recovery Time Objectives and Recovery Point Objectives. 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. Hitachi Command Suite is composed of the following software products:
