Dell HPC NFS Storage Solution High Availability Configurations with Large Capacities

Appendix A: NSS-HA Recipe includes detailed instructions on the configuration steps.
NSS-HA architecture 3.
Figure 3 presents the architectural diagram of the NSS-HA solution. A pair of PowerEdge R710 servers
are configured as an active-passive HA pair and function as an NFS gateway for the HPC compute
cluster (also called the clients).
NSS-HA architectural diagram Figure 3.
Both NFS servers are connected to a shared PowerVault disk storage at the backend. The user data
resides on an XFS file system created on this storage. The XFS file system is exported via NFS to the
clients.
The NFS servers are connected to the clients via the public network. This network can be either
InfiniBand or 10 Gigabit Ethernet. Configuration of the NFS server is shown in Figure 4. It is also
discussed in Section 5.2 that describes the Test bed used to assess this solution.
For the HA functionality of the NFS servers, a private Gigabit Ethernet network is configured to
monitor server health and heartbeat, and to provide a route for the fencing operations. Power to
the NFS servers is driven by two APC switched PDUs on two separate power buses.
