IO Challenge Update 5: 102,240 IOPS
May 21, 2008 – 12:49 pmWe’re really excited to announce that we hit over 100k IOPS!
This was done using 77TB of storage, adding a 3rd rack totalling 495 disks — enough storage to hold the entire printed library of congress, and all being driven from a single ESX server!
Chethan’s just written a detailed report over on VROOM…
The interesting points about this effort to me are:
- There was almost no tuning required
- There is no visible I/O throughput ceiling for ESX — the throughput is roughly that of 50 4-cpu databases…
- Even at 100,000 IOPS, the virtualization layer only added 0.1ms of additional latency, which amounts to 1.4% virtualization overhead

Hi Richard!
I’d like to use some of your numbers in a presentation I am doing. I’d like your permission to do so. Please contact me:

Hi Richard,
Excellent result. A very very high number indeed.
Do we have number for a single VM?
Thank you from Singapore.
