NAS Controller Pair
The PowerVault NX3500 clustered NAS solution consists of two NAS
controllers configured as a pair. The controllers handle load balancing of
client connections, manage read-write operations, perform caching, and
interface with servers and workstations.
The configuration consists of two controllers in a cluster to ensure that there
will be no single point of failure. The PowerVault NX3500 software is installed
on each of the controllers. The software is a complete package, consisting of
an operating system, volume management, distributed file system, and
clustering technology. A virtual IP consolidates all the system's network
interface cards (NICs).
The PowerVault NX3500 is equipped with a built-in traffic load balancing
mechanism that redirects client requests to the least loaded controller,
maintaining an even balance between both controllers in the system.
Read-write operations are handled through mirrored non-volatile RAM
(NVRAM). Cache data is mirrored between the paired NAS controllers, which
ensures a quick response to clients' requests, while maintaining complete data
integrity. Data from the cache to permanent storage is transferred
asynchronously, through optimized data-placement schemes.
