IPoIB large sequential read performance: NSS4-HA vs. NSS3-HA
Figure 6.
5.2. Random writes and reads
This section compares the random write and read performance between the current NSS4-HA release
with a Dell PowerEdge R620 server and the previous NSS3-HA release
(3)
with Dell PowerEdge R710
server. The test parameters, such as number of files, number of runs, and so on, are the same for both
releases.
As disk seek latency is the major factor to determine random write and read performance, and there is
no change in the storage components (hardware and software) between the current and previous
release, it was expected that the test results between the two releases should be similar. However, on
average, about 17 percent improvement for random writes and 23 percent improvement for random
reads were observed during the tests. Such significant improvement is mainly due to the bigger
memory (64GB) deployed in the current release.
Figure 7 and Figure 8 show the random write and read performance, respectively.
