Computing IOPS for SAN: How?
by Jas L. on Jan 3, 2008 at 4:26:37 pm

Happy New Year All:

We are trying to expand a studio and its Edit Suites and would like to implement shared storage/SAN system. In order to evaluate the possibilites, we would like to compute our IOPS (Input Output Operations per Second) in the environment and then look at products that may be able to sustain them.
Every manufacturer has its IOPS published but in our studio enviroment, what would be the best way to compute your IOPS; what kind of numbers your workflow needs.
So let's say, a typical setup would be:
MacPro 3.0GHZ
8GB
2x500GB Internals
Kona3
Capture: ProResHQ, DVCPROHD, Unc. HD
Timeline: Working in ProRes HQ and Uncompressed HD (just to go the extreme)
Playback: 2-3 Uncomp. HD stream (extreme situation)

How would one go about computing average IOPS for this setup?

Thanks a lot
Regards,
Jas
