Dell HPC NFS Storage Solution - High Availability (NSS6.0-HA) Configuration with Dell PowerEdge 13
th
Generation Servers
17
Leveraging the latest PowerEdge R630 server and RHEL 7.0, significant sequential I/O performance
improvements were observed during our tests:
 The peak read performance of NSS6.0-HA was up to 6.07 GB/sec; and there were on average
around 75% improvement as compared to the read performance of NSS5.5-HA
(6)
.
 The peak write performance of NSS6.-HA was up to 2.23 GB/sec, and there were on average
around 14% improvement as compared to the write performance of NSS5.5-HA
(6)
.
IPoIB large sequential write and read performance Figure 3.
5.2. IPoIB random writes and reads
Figure 4 shows the random write and read performance. The figure shows the aggregate I/O operations
per second when a number of clients are simultaneously writing or reading to/from the storage over
the InfiniBand fabric.
From the figure, the random write performance peaks at the 32-client test case and then holds steady.
In contrast, the random read performance increases steadily from 1 to 64-client test cases, indicating
that the peak random read performance is likely to be around 8069 IOPS or more.
