We are running a 4 node hybrid cluster with HP DL380 G9's.

3 disk groups per host. Each group has a 200GB SSD HP MO0200JEFNV (Mainstream Endurance SFF) with 4 900GB 10k SAS magnetic disks per group. (EG0900JFCKB). P440 array controller.

Flow control is enabled.  I did try disabling that before and it did not seem to have any effect.  I'm not seeing any congestion.  Write buffers are not filling up.  A colleague is noting a performance inconsistency when doing sql backups from local disk to local disk on a windows server.  We aren't having any problems with the environment. I'm just trying to see if there's anything that can be done to alleviate these concerns.  Is there a recommended performance testing tool for vsan?

Thanks,

Mike
