Release Notes

24 Analyzing Dell PS Series Storage with SAN Headquarters | TR1050
Observations: Latency is above 25ms. Total IOPS are shy of 3000 from the host, capacity and total iSCSI sessions are
ok.
3.1.1.1 Hardware and firmware details
For a more thorough understanding of the array configuration, the Hardware/Firmware panel provides details. In this
example, the Hardware/Firmware panel shows that two members each in their own pool. The default pool is in a RAID
6 configuration and contains a PS6210E with 7.2K 4TB NLSAS drives. The FASTPOOL15K is a new member added to the
group and contains a single PS6210XV with 15K 146GB drives in a RAID 6 configuration.
Figure 13 Hardware/Firmware shows two pools each with a single member
The default pool contains the volumes in this example and the administrator is aware that only the default pool is
actively in use. The new array and pool were created for future use.
Note that all of the volumes are using the slower drives and additional resources from the new pool are available.
3.1.1.2 Experimental analysis
The Experimental Analysis panel shows the theoritical maximium IOPS based on groups, pools or members chosen. For
instance, when the group is selected, all pools I/O potentials are included in the display. This may be useful for
indicating the overall performance capability of the group in the case of multiple pools. However, in this case the UI is
showing that the system is over the estimated maximum IOPS of the PS Series group even with the presence of the
unused pool.
