Hitachi Virtual Storage Platform N400, N600 hardware overview
Hitachi Virtual Storage Platform N400, N600 are modular, rack-mountable, all-flash arrays that deliver 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.
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.
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:
- Two controllers
- One or more drive trays
- Optional service processor (SVP)
Unified configuration
A unified configuration includes embedded NAS modules that support file system protocols such as CIFS and NFS and 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 N400 model
The VSP N400 is a highly reliable storage 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 and two NAS modules to support file operations. Drives are supported using drive trays connected to the controllers. The maximum number of drives supported is 384 (480 with dense intermix drive tray).
The storage system supports 128 GB of high-speed cache memory. The DIMMs are arranged as 64 GB per controller.
Storage system interfaces consist of:
- 10-Gbps iSCSI: 28 ports per system (or 32 ports per systems for systems without drives or 12 ports per systems when NAS Modules are installed)
- 10-Gbps iSCSI (Copper): 28 ports per system (or 32 ports per systems for systems without drives or 12 ports per systems when NAS Modules are installed)
- 8-Gbps Fibre Channel: 56 ports per system (or 64 ports per systems for systems without drives or 24 ports per systems when NAS Modules are installed)
- 16-Gbps Fibre Channel (2-port): 28 ports per system (or 32 ports per systems for systems without drives or 12 ports per systems when NAS Modules are installed)
- 16-Gbps Fibre Channel (4-port): 56 ports per system (or 64 ports per systems for systems without drives or 24 ports per systems when NAS Modules are installed)
- 32-Gbps Fibre Channel (4-port): 56 ports per system (or 64 ports per systems for systems without drives or 24 ports per systems when NAS Modules are installed)
