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.
Key features
- Multiple controller configuration distributes processing to each controller
- High-speed processing facilitated by up to 1,024 GiB of cache
- I/O processing speed increased by NVMe flash drives
- High-speed front-end data transfer up to 3.2 GB/s for FC and 1 GB/s for iSCSI
- Response times as low as 64 microseconds
- Integrated with Hitachi Ops Center to improve IT operational efficiencies
- Service continuity by main components in redundant configuration
- RAID 1, RAID 5, and RAID 6 support (RAID 6 including 14D+2P)
- Data security by transferring data to cache flash memory at the time of a power outage
- Scalable capacity up to 2.88 PB (internal), 287 PB (external), and 5.8M IOPS
- Heterogeneous connectivity supporting concurrent attachment to a variety of hosts, including VMware, Linux, UNIX, and Windows
