In the testing/playing phase with a bunch of new SAN/Server kit.
I have 2 x Procurve 2910 switches dedicated to iSCSI/vMotion (with a 10gbps fibre link between them), 2 x vSphere hosts (each with lots of NICs), and 6 x P4000 iSCSI nodes.
The P4000 manuals say to enable flow control on the switches.
I'm not clear if that means enable it globally, or just on the ports that the P4000 nodes are directly connected to?
I'll be mounting iSCSI volumes from both the vSphere hosts, and from within some of the guests (Windows 2008 DSM MPIO).
I know what flow control does at a basic level, but I don't know enough about it at low level to know where I should be implementing it.
