MD3460 and MD3060e Storage Arrays
5
Executive summary
This solution guide describes the Dell NFS Storage Solution - High Availability configurations (NSS-HA)
with Dell PowerVault MD3460 and MD3060e storage arrays. The PowerVault MD3460 and MD3060e are
the latest generation high-density storage enclosures that provide up to 60 3.5” drives in 4U of rack
space and support 12GBbps SAS connectivity. This solution guide presents a comparison between all
available NSS-HA offerings so far, and provides performance results for a configuration with a storage
system capacity of 360TB.
The NSS-HA solution described here is designed to enhance the availability of storage service to the
HPC cluster by using a pair of Dell PowerEdge servers and PowerVault storage arrays along with Red Hat
HA software stack. As in previous versions of Dell NSS-HA solution guides, the goal of this solution guide
is to improve storage service availability and maintain data integrity in the presence of possible failures
or faults and to maximize performance in a failure-free scenario.
