MSA1510i / vsphere not homogeneous performance


MSA1510i / vsphere not homogeneous performance

I'm facing strange behaviours on performances.
MSA1510i with double controller and 4 active gigabit ports, DL585 G2 vSPhere host with 4 dedicated gigabit ports for iSCSI.
Switch is a Procurve 2810-24G.
When moving huge files between two Win 2003 virtual servers (copy to remote folder) within the DL585 G2 host, same operations speed can be 70MB or 5MB without apparent reason.
The virtual machines are on different volumes of MSA1510i, binded to different NICs.
Host is dedicated, none else is working on the switch or with MSA1510i.
How there can be such huge difference in speed repeating the same operation more times?
Any hint on what to check?

Re: MSA1510i / vsphere not homogeneous performance


AFAIK the 1510i isn't supported because the MSA doesn't support SCSI-3. This could cause the problems.

Best regards,
