4 Dell HPC NFS Storage Solution – High Availability (NSS7.0-HA) Configuration
Executive summary
This Dell technical white paper describes the Dell NFS Storage Solution—High Availability configuration
(NSS7.0-HA). The paper compares all available NSS-HA offerings so far, and provides performance results
for a configuration with a storage system providing 480 TB of raw storage capacity.
The NSS-HA solution described here is designed to enhance the availability of storage services to the HPC
cluster by using a pair of Dell PowerEdge servers and PowerVault storage arrays along with Red Hat HA
software stack. The goal of the solution is to improve storage service availability and maintain data
integrity in the event of possible failures or faults and to optimize performance in a failure-free situation.
