The Hitachi Virtual Storage Platform Midrange G Series hybrid and F & E Series all flash models are built on the high-end VSP design with configurations that use two purpose-built controllers, the same embedded software, and differing physical packaging. The VSP E990 model was introduced in April 2020 and expanded with additional models in December 2020 and are all NVMe storage systems. The hardware uses standard Intel components with no custom ASICs as were used on previous Hitachi midrange systems. The embedded Storage Virtualized Operating System RF (SVOS RF) is a singular code stream for Hitachi block storage systems. Advances in the technology have increased performance, expanded usability with active-active stretched clusters, extended storage virtualization with Virtual Storage Machines (VSMs), and added non-disruptive scale out capabilities to extend the life of the system.

The seamless continuation of the high-end Hitachi VSP series systems will allow customers familiar with the earlier systems to expand on their value derived from the system with the new capabilities and performance. Environments for midrange storage can be expanded with the new capabilities and simplified operations of the VSP E, G, and F series. The VSP G series supports both block and file access with file support coming with the high performance HNAS included with the specific G model (as an option) as a single inserted card in the VSP chassis. The HNAS supports up to eight nodes in a cluster. The F Series and the E-series support block mode only.

In May 2018, Hitachi refreshed the product line with new Intel processors and other updates and changed the product model numbers. The E990 was introduced in April 2020.

Highlights of the VSP midrange systems include:

  • Four hybrid models that vary in configurations: G350, G370, G700, G900
  • Four all flash models: F350, F370, F700, and F900
  • All NVMe systems – E990, E790, E590
  • Continuation of Hitachi VSP high-end hardware design using standard Intel components in a purpose-built system
  • Embedded software SVOS RF – Storage Virtualized Operating System RF
  • Hitachi Storage Advisor – management application with GUI for configuration and provisioning
  • Block and file support with HNAS under the covers (G-Series) – up to 8 HNAS nodes in cluster
  • External storage system virtualization
  • Thin provisioning for external volumes, fat-to-thin conversion
  • Real-time tiering as cache extension
  • Automated Dynamic Tiering (G-Series)
    • FMDs, SSDs, SAS, and NL-SAS devices
  • Inline compression in FMDs (not in E990)
  • Software based compression and deduplication
  • E990 – all NVMe devices
