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.
Key features
- Multiple controller configuration distributes processing across controllers
- High-speed processing facilitated by up to 768 GiB of cache
- I/O processing speed increased by NVMe flash drives
- High-speed front-end data transfer up to 32 Gbps for FC and 10 Gbps for iSCSI
- I/O response times as low as 66 μs
- Integrated with Hitachi Ops Center to improve IT operational efficiencies
- Service continuity for all main components due to redundant configuration
- RAID 1, RAID 5, and RAID 6 support (RAID 6 including 14D+2P)
- Data security by automatically transferring data to cache flash (non-volatile) memory during a power outage without any intervention
- VSP E590: Up to 8.9 PB (internal and SAS expansion), 144 PB (external), and 4M IOPS
- VSP E790: Up to 8.9 PB (internal and SAS expansion), 216 PB (external), and 6.8M IOPS
- Heterogeneous connectivity supporting concurrent attachment to a variety of hosts, including VMware, Linux, UNIX, and Windows
Storage system specifications
