Also, how are you accessing Ceph - is it using the TGT iSCSI package?

Hello guys,

We're testing running an esxi hv on top of a ceph backend and we're getting abysmal performance when using vmfs, has anyone else tried this successful, any advice ?
Would be really thankful for any hints.

Hi!

I don't have a ton of experience with esxi, but if you can do some rados bench or smalliobenchfs tests, that might help give you an idea if the problem is Ceph (or lower), or more related to something higher up closer to exsi.  Can you describe a little more what you are seeing and what you expect?

Thanks,
Mark
