NAS Gateway (Nh4c & Nh8c) empowers M Series Disk Array by supporting NAS (file data access) protocol interface
- • Supports multi-protocol host interfaces to unify SAN and NAS system.
- • File systems can be expanded online.
- • Convenient Planning for maximum performance with virtual server function.
- • Saving storage space with single instance function (file based deduplication).
- • Efficient remote backup in NAS environment.
- • Snapshot with as many as 992 generations.
- • High availability by cluster configuration.
Supports multi-protocol host interfaces to unify SAN and NAS system
NAS Gateway enables M Series Disk Array to support both SAN (block data access) and NAS (file data access) and converged multi-protocol host interfaces.
Continuous operation with online expansion of a file system
Many file systems can be aggregated into an M Series storage, each file system in M Series can be expanded up to 1PB. Physical drives can be added when required to increase the capacity of file system online, so operation and management of increasing contents is easier with M Series and NAS Gateway.
Convenient Planning for maximum performance with virtual server function
You can plan for maximum performance by optionally designating “virtual servers” to be assigned to a node. You can change the physical startup node of a virtual server or allow it to use system managed default startup node. This functionality allows you to equalize the load on each physical node by organizing virtual servers based on criteria (such as the number of clients connected) that results in balancing the load on each physical node by using “virtual servers”. You can also ensure the performance of a priority workload by separating it from other virtual servers and allocating it to a dedicated physical nodes to protect throughput.
Saving storage space with single instance function
M Series with NAS Gateway has a single instance function (file based deduplication) to make a clone when detecting redundant file data by checking files based on a preset policy such as access time and suffix of file names. This function can drastically reduce the physical capacity required for the M Series system.
Efficient remote backup in NAS environment
Remote backup of file systems through an IP network with NAS Gateway. This function provides a server-free backup system. Up to four M Series storages can be connected to a NAS Gateway and remotely backed up.Replication software of M Series also can be used for file data.
Snapshot with as many as 992 generations
The NAS Gateway Snapshot function provides up to 992 generations of differential data. This differential data can be quickly recovered via the snapshot function to repair files corrupted by operation or application error.
High availability with cluster configuration
As NAS Gateway is a two-node cluster, it is operational even in the face of a hardware failure, and a part replacement can be done online.
