Dell PowerVault MD3260 - Manual (Page 8)

If the iSCSI initiators are connected to MD3200i and/or
MD3600i series through the network switches, make
sure that your switches support IEEE 802.3x flow
control, and the flow control is enabled for both
sending and receiving on all switch ports and server
NIC ports.
If you do not enable the flow control, your iSCSI
storage array may experience the degradation of the
I/O performance.
In addition to enabling the Ethernet IEEE 802.3x flow
control it is also recommended to disable unicast
broadcast storm control on the switch ports connected
to the iSCSI initiators and target arrays and turn on the
"PortFast" mode of the spanning tree protocol (STP) on
the switch ports connected to the iSCSI initiators and
target arrays.
Note that turning on the "PortFast" mode is different
from turning off the whole operation of STP on the
switch. With "PortFast" on, the STP is still enabled on
the switch ports. Turning STP off may affect the entire
network and can leave the network vulnerable to
physical topology loops.

For optimal I/O performance, avoid having more than
one iSCSI session originating from one host iSCSI port
to the same controller. Ideally, the iSCSI host NIC
should be connected to only one iSCSI target port on
the storage subsystem.
