Chapter 1: Introduction
The Hitachi Virtual Storage Platform E590 (VSP E590) and Hitachi Virtual Storage Platform
E790 (VSP E790) storage systems are high-performance, large-capacity data storage
systems utilizing all-flash NVMe solid-state drives. The storage system consists of a
controller chassis and internal components such as fans and PCIe switches.
The NVMe architecture delivers consistent, low-microsecond latency which reduces the
transaction costs of latency-critical applications and delivers predictable performance to
optimize storage resources.
