Hitachi VSP N800

The Hitachi Virtual Storage Platform N800 is a rack-mountable, modular storage system that supports different FMD DC2 flash storage device configurations with set storage capacities. Hard disc drives are available in an all-flash configuration to deliver consistent low latency host response times and best IOP performance across all host connection ports. The storage system has two controllers, each of which has a processor, two DIMMs for in-line cache memory, a CFM for cache flash memory, a battery, fans, and I/O modules for iSCSI and Fibre Channel. For out-of-band management, each controller also has an Ethernet connection. All data discs remain accessible to data hosts utilising redundant data through the other controller if the data path through one controller fails. Embedded network-attached storage (NAS) modules can be installed in the storage system. File access is provided by the NAS modules using the CIFS and NFS protocols, while the iSCSI protocols provide block access. Every storage system model enables the exchange of bad drives without affecting hosts' access to their data. To ensure the fault-tolerant integrity of the logical drives, a spare hot drive can be set up to replace a failed drive automatically. Self-contained, hardware-based RAID logical drives offer maximum performance in small external enclosures. Essential hardware components are constructed in a redundant configuration to ensure that the storage system can keep running even if a component fails. While the storage system is running, changes to the firmware and component replacements can be made.
