Team, Have a performance related question on Ceph.
I know performance of a ceph cluster depends on so many factors like type of storage servers, processors (no of processor, raw performance of processor), memory, network links, type of
disks, journal disks, etc. On top of the hardware features, it is also influenced by the type of operation you are doing like seqRead, seqWrite, blocksize, etc., etc. Today one way we demonstrate performance is using benchmarks and test configurations. As a result, it is difficult to compare performance without understanding the underlying system
and the usecases. Now coming to my question. Is there a Ceph performance calculator, that takes all (or some) of these factors and gives out an estimate of the performance you can expect for different
scenarios? I was asked this question, I didn’t know how to answer this question, I thought of checking with the wider user group to see if someone is aware of such a tool or knows how to do this calculation. Any pointers will be appreciated. Thanks, - epk Legal Disclaimer: The information contained in this message may be privileged and confidential.
