Dell HPC NFS Storage Solution - High Availability Configurations
Page 3
Executive Summary (updated May 2011)
This solution guide describes the Highly Available configurations of the Dell HPC NFS Storage Solution
(NSS). Guaranteeing high availability (HA) of user data is becoming a common requirement in HPC
environments. The HA configurations of Dell NSS improve availability of data using a pair of NFS
gateway servers in an active-passive configuration to provide data access to the HPC compute cluster.
The goal is to improve service availability and data integrity in the presence of possible failures or
faults, and to maximize performance in the failure-free case. Described here are the architecture,
performance and best practices for building such solutions.
Version 1.1 of the solution guide, dated May 2011, includes updated 10 Gigabit Ethernet performance
results.
