27 Best Practices for Sharing an iSCSI SAN Infrastructure with Dell PS Series and SC Series Storage using VMware vSphere
Hosts | 2015-A-BP-INF
The following figures show the baseline IOPS and latency information gathered on the PS Series environment
and how it compares after the introduction of the SC Series storage to the environment. Figure 4 and Figure 5
show the baseline information on the left and the shared environment data on the right, as a percentage of
the baseline. As shown in the charts, there was no significant decrease in IOPS nor increase in latency with
the introduction of the SC Series storage platform to the environment.
Shared host performance data: 8K and 64K
Shared host performance data: 256K read and write
