NAS e7000 v2 as a Clustered Pair Attached to a SAN
In the clustered configuration, two NAS devices are linked via a private network
and have access to shared storage as illustrated in
deployments, it is recommended that each NAS device be attached to the SAN via
a pair of fiber channel HBAs. Dual HBAs per NAS device is recommended but
not required for cluster deployments, since dual HBAs allow for path failure
without causing node failover in the cluster.
For the NAS e7000 v2, cluster setup requires at least three LUNs. One LUN is
required for the quorum disk and two LUNs are required for data disks. Individual
data disks specific to each node are required for the proper setup of file sharing
where both nodes participate in file-sharing activities. Clustered NAS systems
have the ability to provide redundant active/active access to file shares on disk.
However, as with all Microsoft-based clusters, the unit of ownership among nodes
is at the disk level. Therefore, individual fileshares can be accessed by only one
node at a time based on which node owns the disk.
