Hitachi VSP E990 - Chapter 1: Introduction; Key Features; Storage System Specifications

Chapter 1: Introduction
The Hitachi Virtual Storage Platform E990 (VSP E990) storage system is a high-performance,
large-capacity data storage system utilizing all-flash NVMe solid-state drives. The storage
system consists of a controller chassis, one or more NVMe drive boxes, 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.
