Webinar: How Many IOPS Do You Really Need?

How Many IOPS Webinar Cover SlideEarlier 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.
