Dell HPC NFS Storage Solution High Availability (NSS-HA) Configurations with Dell PowerEdge 12th
Generation Servers
9
56Gb fourteen data rate (FDR) as well as increased memory capacity and bandwidth. The storage
subsystem hardware remains unchanged.
Table 1 lists all the Dell NSS-HA solutions with standard configurations. In addition to the standard
configurations in Table 1, a special NSS-HA configuration, XL configuration is also available. The NSS-
HA-XL provides two storage system services running 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 that host the two storage services. The NSS-HA-XL solution uses the same
hardware and software as required in the standard configurations but with twice the number of
PowerVault storage enclosures compared to the NSS-HA 288TB standard configuration. For more
information about this special configuration, refer to the blog post titled “Dell NFS Storage Solution
with High Availability – XL configuration”.
