Hi,
we have 1 ESX and 1 ESXi physical hosts, two iscsi SAN appliances: a dell MD3000i and a openfiler/linux one.
2 dedicated switches (dlink DGS-1216T) are managing iscsi traffic:the two SAN appliances have at least 2 ethernet NICS (cross) connected to the two switches.
each ESX/ESXi physical hosts has 2 dedicated physical NICs for iscsi, teamed for passive failover.
On the SAN we'll have a number of iscsi VMFS volumes, plus one iscsi volume directly accessed from within a win2k03 VM via MS iscsi initiator (they share the same pNICs and vNICs)
I read as much as I could on iscsi and I received (very appreciated) help from vmware community about building a good iscsi SAN but I'm still unsure about flow control. I suppose It's best to activate it on every part of the iscsi LAN. So:
-on our dlink 1216T switches I can selectively enable flow control, port by port;
-I unnderstand that dell MD 3000i auto-sets flow control on its NICs, if it finds flow control active on the corresponding switch port;
-I'm going to check how to enable flow control on openfiler/linux
-BUT what about ESX/ESXi? Do I need flow control on? if so, how can I enable flow control on pNICS and/or vNICS?
Thank you in advance
Guido
