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:
The Hitachi VSP midrange systems are targeted for usage across the midrange enterprise space for the demanding applications and as a platform to be used for consolidation with the ability to virtualize other storage systems behind it. A full complement of advanced features is available with the Hitachi VSP series including system management and analytics software.

The Hitachi Data Systems VSP midrange systems, the E and F models for all flash and G models for hybrid, are high-function block storage systems with an internal addition of the HNAS file storage as plug-in cards. The NAS function is similar to a bolt-on solution in that it is operating independently of the block function. The maturity of the NAS implementation includes a full spectrum of file protocols, more than is usual in the mid-tier and entry markets. Additionally, the NAS is a hardware-intensive implementation using FPGAs for greater performance. A full suite of advanced features is also available.
The VSP systems support storage virtualization to allow attachment of external storage systems for use as another tier of storage or for migrating data.
The VSP midrange systems are not scale-out systems, which means for increasing performance in parallel with capacity, a new controller pair (another model) must be installed. Other competitive systems have implemented scale-out functionality for a more measured growth. Evaluator Group believes the experience in the high-end enterprise and the demonstrated reliability of the large VSP system executing the same embedded software means the VSP midrange systems are low-risk, high functional value storage solutions. The lack of scale-out is one limitation that must the managed by the customer with choosing the correct model and planning for replacements on pace with coupled capacity and performance demands.
