I do not normally touch network side and am struggling getting my head around exact requirements/preferences for iSCSI traffic. So, I thought I'd break down to see if I get a consensus. I have a single HP 2810 switch for the iSCSI traffic and have 3 Vmware hosts and a small SAN with 6 ports plugged into the switch. My issue is the Vmware side seems to disconnect from SAN and I have been going around with Vmware, SAN vendor and switch vendor. Hosts have multiple iSCSI NICs and vNIC configured round robin.
I have updated to most current firmware on both and Vmware 5.1. SAN vendor says that iSCSI session is dropping after 5 min or so. Basically Vmware performs slowly all day.
Spanning tree- I have heard both ways whether it should be enabled or not. Last version I read said enabled but set for edge on HP switch. Can't find exact guide on how to do this.
Flow control- I have not had this set and want to try and several references suggest.
Jumbo frames- I do not have configured across as I did not want to introduce new issues until I resolved original.
Any other suggestions or settings on the iSCSI switch side, let me know? I am attaching my current config on switch 1 and I am about to add sw2 so I don't have the multiple VLANs (so I will be transplanting the storage VLAN configuration).
