Hello,

I use cluster VMware with 2 host connect by iSCSI to DSS V7, then I have 1 volume (about 14TB) attach iSCSI target. During backup virtual machine I see in log of vcenter this problem "I/O latency increased from average value....." increase upto 600000 microsecond sometime. This problem to little time. But come every time I try use storage with much work. Host connect to storage with 1Gb/s link each one, then storage has 1 link 1Gb/s dedicated to iSCSI.
I follow tuning vmware with iscsi on blog open-e but not change any. I haven't real problem but I think 600000 microsecond of latency is very high.
Can u give me some helps ? Thanks

M.
