Last week, via a tweet from Frank Denneman, I discovered a whitepaper that covers the differences between storage IOPS and storage throughput, as well as best practises for performance benchmarking.
As someone relatively new to the inner workings of storage, I found it very enlightening. Particularly the fact that there’s a clear difference between IOPS and throughput, and you need to decide what you want from a storage system before you benchmark it. Well worth a read, even if it’s the first 9 pages which covers the different types of workload (IOPS vs Storage).
The whitepaper from EMC is here: Elements Of Performance And Testing Best Practices Defined
Frank’s post, with a summary of the white paper is here: Awesome read: Storage Performance And Testing Best Practices
Share and enjoy 🙂
