42 Analyzing Dell PS Series Storage with SAN Headquarters | TR1050
Figure 27 SQL Insert commands loading tables show IOPS exceed the estimated maximum IOPS, however
performing with low latency
From the Experimental Analysis panel, the overall I/O load appears to indicate that this PS Series group is exceeding its
capabilities. However, latency is below 15ms. For this part of the application 15ms latency is acceptable.
The actual pressure on the disks should also be verified by clicking Hardware / Firmware > Disks as shown below. For
the time interval selected, the table data shows each disk is well below the rule of thumb maximum of 185 IOPS per
disk.
Latency looks good
Actual IOPS > MAX
