Hi list:
my cluster include 4 server ,12 osd(4 osd/server), 1 mon(1 server), 1Gbps link, ceph version is 0.72 , the cluster status is ok, client is vmware vcenter.
use rbd as tgt backend,expose 2TB LUN via iscsi to vmware,the performance is very bad. the bw just 10kB/s.
but when use windows7 as client via iscsi the performance is ok nearly 100MB/s
why the performance is so bad when client is vmware?
