Chapter 1: Introduction
The Hitachi Virtual Storage Platform VSP E590 and VSP E790 storage systems are high-
performance, large-capacity data storage systems. The VSP E590 and VSP E790 all-flash
arrays (AFAs) support NVMe and SAS solid-state drives (SSDs). The VSP E590H and VSP
E790H hybrid models can be configured with both SSDs and hard disk drives (HDDs).
■
The NVMe flash architecture delivers consistent, low-microsecond latency, which reduces
the transaction costs of latency-critical applications and delivers predictable performance
to optimize storage resources.
■
The hybrid architecture allows for greater scalability and provides data-in-place migration
support.
The VSP E590 and VSP E790 storage systems consist of a controller chassis, one or more
drive boxes for hybrid models, and internal components such as fans and PCIe switches.
