Hitachi Virtual Storage Platform G200 hardware overview
The Hitachi Virtual Storage Platform G200 is a modular, rack-mountable storage array that delivers high performance, high reliability, and flash-accelerated scalability.
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.
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.
Essential hardware components are implemented with a redundant configuration so that the storage system can remain operational if a component fails. Adding and replacing components, along with firmware upgrades, can be conducted while the storage system is active.
Block configuration
A storage system configured for 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:
- One dual controller chassis with on-board drives
- One or more optional drive trays
- Optional service processor (SVP)
VSP G200 model
The VSP G200 is highly reliable storage system that offers high storage capacity with full redundancy to better protect data and manage storage operations.
The VSP G200 consists of the following:
- A 2U enclosure that includes two controllers, and either 24 small factor form factor (SFF) disk drives or 12 large form factor (LFF) disk drives.
- An associated number of drive trays.
The VSP G200 supports 64 GB of high-speed cache memory. The DIMMs are arranged as 32 GB per controller.
The VSP G200 interfaces consist of:
- 10-Gbps iSCSI: 8 ports per system
- 10-Gbps iSCSI (Copper): 8 ports per system
- 8-Gbps Fibre Channel: 16 ports per system
- 16-Gbps Fibre Channel (2-port): 8 ports per system
- 32/16-Gbps Fibre Channel (4-port): 16 ports per system
