Hi All, I have a Ceph cluster that consists of 3 OSDs (each on a different server’s SSD disk partition with 500MB/s maximum read/write speed). The 3 OSDs are connected through a switch which provides a maximum 10 Gbits/sec bandwidth between each pair of servers. My Ceph version is Luminous 12.2.5. I’ve set up a Ceph FS using BlueStore and Erasure Coding pool (k=2, m=1). What is the theoretical upper bound of read and write speed of my Ceph FS? Many thanks.
