Hello Experts , I want to increase my Ceph cluster's read performance.
I have several OSD nodes having 196G RAM. On my OSD nodes Ceph just uses 15-20 GB of RAM. So, can i instruct Ceph to make use of the remaining 150GB+ RAM as read cache. So that it should cache data in RAM and server to clients very fast. I hope if this can be done, i can get a good read performance boost. By the way we have a LUSTRE cluster , that uses extra RAM as read cache and we can get upto 2.5GBps read performance. I am looking someone to do with Ceph. - Vickey -
