Dell HPC NFS Storage Solution High Availability (NSS-HA) Configurations with Dell PowerEdge 12th
Generation Servers
5
Executive summary
This solution guide describes the Dell NFS Storage Solution High Availability configuration (NSS-HA) with
Dell PowerEdge 12
th
generation servers. It presents a comparison between all available NSS-HA
offerings so far, and provides tuning best practices and performance details for a configuration with a
storage system capacity of 288TB and two Dell PowerEdge 12th generation servers (R620).
The NSS-HA solution described is designed for high availability using a pair of NFS servers in active-
passive configuration to provide storage service to the HPC compute cluster. As in previous versions of
Dell NSS-HA solution guides, the goal is to improve service availability and maintain data integrity in
the presence of possible failures or faults, and to maximize performance in the failure-free case.
