I am about to configure an i2.8xlarge EC2 instance for the management server and i2.xlarge for collectors. They are all storage optimized EC2 instances, which means very high IOPS. the IOPS can be Provisioned as well. I am just curious that whether there is a minimum number that I should be looking at considering that I am deploying a xLarge96 management server and a fully loaded collector group. I know this is a high level question without going into too much details that are required for correct sizing

Did you see this page and the IOZone downloads?

I looked at those links but that doesn't help much. It will give an idea say, " The more IOPS it is better" kind of impression rather than a typical figure or approximation. I know it is very difficult to calculate this exactly but a scenario with very large implementation example would have been useful.
probably I have to experiment with my deployment and then could post a figure in next 3 to 6 months.

Jiji, It's great to see a focus on IO capacity. But it's hard to define the requirements without knowing more about the size of the system. Number of agents, Agent type, Number of Data centers, And most importantly: Number of transactions/sec.
There's a lot written up on this topic in the doc. Did you take a look? There's also a sizing spreadsheet that is very helpful in answering these types of questions.
