Hitachi Virtual Storage Platform F400, F600 hardware overview
Hitachi Virtual Storage Platform F400, F600 are modular, rack-mountable, all-flash array storage systems.
The storage systems contain dual controllers for communicating with a data host. Each controller contains its own processor, dual in-line cache memory modules (DIMMs), cache flash memory (CFM), battery, and fans. Each controller also has an Ethernet connection for out-of-band management. If the data path through one controller fails, all hard drives remain available to data hosts using a redundant data path through the other controller. The storage system controllers are replaceable.
The storage system can be equipped with network-attached storage (NAS) modules. The NAS modules provide file access through CIFS and NFS protocols and block access by using iSCSI protocols, in addition to the block access provided directly by iSCSI and Fibre Channel I/O modules.
All storage system models allow defective drives to be replaced without the interruption of data availability to host computers. A hot spare drive can be configured to replace a failed drive automatically, securing the fault-tolerant integrity of the logical drive. Self-contained, hardware-based RAID logical drives provide maximum performance in compact external enclosures.
Key components are implemented with a redundant configuration, so that the storage system can remain operational in the unlikely event that a component should fail. Adding and replacing components, along with firmware upgrades, can be conducted while the storage system is active.
Block configuration
A block-level storage provides the ability to access and provision raw storage volumes using protocols such as Fibre Channel and iSCSI.
A block configuration consists of the following:
- Two controllers
- One or more drive trays
- One 1U block service processor server (SVP)
Unified configuration
A unified configuration includes NAS modules that support file system protocols such as CIFS and NFS operate across a block-level setup using iSCSI or FC connections.
- Two controllers
- Two NAS modules for file operations and storage
- One or more drive trays for block-level storage
- One 1U block service processor server (SVP)
VSP F400 model
The VSP F400 is a highly reliable all-flash system that offers high storage capacity with full redundancy to better protect data and manage storage operations.
The storage system consists of a 4U enclosure that includes two controllers, two optional NAS modules to support file operations, but without disk drives. Drives are supported using drive trays connected to the controllers.
