This line consists of mid-range and high-end enterprise models with differing capabilities. Currently supported models include: G350, G370, E590, G700, E790, G900 and E1090 for mid-range systems; G1000, G1500 and 5000-series for high-end enterprise systems. ==History == Hitachi Virtual Storage Platform, also known as VSP was first introduced in September, 2010.{{cite web | url= http://www.hds.com/corporate/press-analyst-center/press-releases/2010/gl100927b.html | title= Hitachi Data Systems Unveils the World's First 3D Scaling Storage Platform for Unprecedented Cost Savings and Agility | publisher= Hitachi Data Systems l | accessdate= 2010-10-28 | archive-date= 2010-10-24 | archive-url= https://web.archive.org/web/20101024092642/http://www.hds.com/corporate/press-analyst-center/press-releases/2010/gl100927b.html | url-status= dead }} This storage platform builds on the design of [Universal Storage Platform](/source/Universal_Storage_Platform) V, originally released in 2007.{{cite web | url= http://www.networkcomputing.com/storage-networking-management/hitachi-data-systems-unveils-3d-scaling-storage-platform.php |title= Hitachi Data Systems Unveils 3D Scaling Storage Platform | publisher= Network Computing | accessdate=2010-10-28}} == 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 6 Gbit/s [SAS](/source/Serial_attached_SCSI) 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](/source/Solid-state_drive), [SAS](/source/Serial_attached_SCSI) and [SATA](/source/Serial_ATA) drives.{{cite web | url= http://www.hds.com/assets/pdf/hitachi-analyst-report-hds-unveils-virtual-storage-platform-impact-report-451.pdf | title= HDS unveils 3D scaling with revamped flagship: the Virtual Storage Platform | publisher= the 451 Group | accessdate= 2010-10-28 | archive-date= 2010-10-08 | archive-url= https://web.archive.org/web/20101008193228/http://www.hds.com/assets/pdf/hitachi-analyst-report-hds-unveils-virtual-storage-platform-impact-report-451.pdf | url-status= dead }} Features included:{{cite web | url= https://www.hds.com/assets/pdf/virtual-storage-platform-family-datasheet.pdf | title= Hitachi Virtual Storage Platform Datasheet | publisher= Hitachi Data Systems | date= February 2016 | accessdate= October 2, 2016 | archive-date= October 21, 2016 | archive-url= https://web.archive.org/web/20161021121005/https://www.hds.com/assets/pdf/virtual-storage-platform-family-datasheet.pdf | url-status= dead }} *The ability for growth in three ways: **[Scale up](/source/Scalability) 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](/source/Scalability) 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](/source/Hierarchical_storage_management), 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](/source/Storage_virtualization) of external SAN storage from Hitachi and other vendors into one pool *Supports online local and distance [replication](/source/Replication_(computer_science)) and [migration](/source/Data_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.{{cite web | url=http://www.hds.com/assets/pdf/hitachi-overview-virtual-storage-platform.pdf | title= Hitachi Virtual Storage Platform Overview | publisher= Hitachi Data Systems |date= September 2010 |archivedate= October 9, 2010 |archiveurl= https://web.archive.org/web/20101009033000/http://www.hds.com/assets/pdf/hitachi-overview-virtual-storage-platform.pdf |accessdate= October 2, 2016 }} *Automated [wide-striping](/source/Data_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.
