Earlier today Tom Coughlin and I presented a BrightTalk webinar in league with the Storage Networking Industry Association (SNIA) to discuss our joint report: How Many IOPS is Enough?
The report is based upon a survey that asked IT managers about their enterprise IOPS requirements. The webinar gives a taste of the report’s contents, and explains the survey methodology. During the course of the webinar and at the end Tom and I answered a number of listener questions relating to the content.
The presentation also includes a little plug for SNIA’s client IOPS survey which is being run by downloading a program called the Workload I/O Capture Program, or “WIOCP.”
A replay of this webinar is available on the BrightTalk website.
The presentation was well received by our audience. Have a listen.
