The infrastructure of the NSS-HA solution
Figure 1.
Note: The iDRAC 7 enterprise is not shown in the figure, and it is installed on each NFS server for Dell
NSS-HA solutions. The term of Network Power Switches refers to APC PDU (Power Distribution Unit) in
Dell NSS-HA solutions.
2.2. NSS-HA offerings from Dell
Table 1 lists all of the Dell NSS-HA solutions with standard configurations. In addition to the standard
configurations, a special NSS-HA configuration, XL, is available for all NSS-HA versions.
The NSS-HA-XL configuration provides two independent storage system services concurrently, along
with the high availability functionality, but instead of one active-passive failover pair, the solution is
designed as two active-passive failover pairs to host the two storage services. Each server is the active
host for one of the storage arrays and passive for the other storage array. The NSS-HA-XL configuration
uses the same hardware and software as required in the standard configurations, except it requires
twice the number of PowerVault storage arrays than the NSS-HA standard configuration.
For more information about this special configuration, refer to the blog post titled Dell NFS Storage
Solution with High Availability – XL configuration
