Seeking for recommendations on setting up multiple Lustre file system
"versus" creating multiple pools with exclusive OST's.
We have two sets of disks SAS vs SATA and would like to separate them. I have created
exclusive OST pools and they seem to work fine, but I am looking for recommendations
before we go into production with this setup.
We have 12 OSS and all of the SAS & SATA OST's are evenly spread across 12
OSS's.
Any thoughts on this is greatly appreciated.
I suspect you would get ~2x the iops if you used 2 fs's and 2 MDS's.
if you're already running an active/passive MDS pair then this would
mean no extra hardware.
cheers,
