We back some of our ceph clusters with SAN SSD disk, particularly VSP G/F and Purestorage. I’m curious what are some settings we should look into modifying to take advantage of our SAN arrays. We had to manually
set the class for the luns to SSD class which was a big improvement. However we still see situations where we get slow requests and the underlying disks and network are underutilized.
More info about our setup. We are running centos 7 with Luminous as our ceph release. We have 4 osd nodes that have 5x2TB disks each and they are setup as bluestore. Our ceph.conf is attached with some information
removed for security reasons. Thanks ahead of time.
