The Hitachi Virtual Storage Platform F800 is a modular, rack-mountable all-flash array storage system, with various fixed storage capacity configurations of FMD DC2 flash storage devices. To deliver consistent low latency host response times and highest IOP performance across all host connection ports, hard-disk drives are supported in an all-flash configuration.
The storage system contain dual controllers, each controller contains its own processor, dual in-line cache memory modules (DIMMs), cache flash memory (CFM), battery, fans and iSCSI and Fibre Channel I/O modules. Each controller also has an Ethernet connection for out-of-band management. If the data path through one controller fails, all data drives remain available to data hosts using a redundant data path through the other controller.
The storage system can be equipped with embedded network-attached storage (NAS) modules. The NAS modules provide file access through CIFS and NFS protocols and block access by using iSCSI protocols.
All storage system models allow defective drives to be replaced without the interruption of data availability to hosts. A hot spare drive can be configured to replace a failed drive automatically, securing the fault-tolerant integrity of the logical drives. Self-contained, hardware-based RAID logical drives provide maximum performance in compact external enclosures.
