Can someone please help me with below details.
Application Short Name | Application Long Name | Release | VM Name | Min IOPS/instance | Typical IOPS | Max IOPS | IOPS Block Size | CPU Util Min Treshold | IO Wait Min Treshold | Network Bandwidth Requirements |
CUCM | Unified Communications Manager Release | 11.0 | CallCtrl: 150 users | |||||||
CUC | Unity Connection Release | 11.0 | 1,000 users | |||||||
CUCCX | Cisco Unified Contact Center Express / Unified IP IVR Release | 11.x | Main: 100 agents | |||||||

Hi Aniket,
As per my understanding and according to the snap you want to check for the IOPS for the specific version.
As rightly mentioned by Jonathan, IOPS will vary depending upon the activity in your cluster like : sending data to billing servers, collecting logs, backups.
Also IOwait indicates high disk I/O activities, The number of CPUs you have affects your percentage
I have seen high Iowaits causing issues, High Iowait can be due to several reasons : Hardware, db etc.
Anything over and above 25-30 % should be a concern.
You can use the perfmon tool to isolate and troubleshoot further.
Thanks & Regards

This is, to some extent, implementation/load-dependent. The only data I am aware of Cisco publishing on this front is here:
For example, clicking on CUCM shows some IOPS related data at the bottom of the page:
