I'm planning to use a stacked pair (using 48g stacking modules) of 6248s atop my rack for server and storage network connections and some LAG connections back to my core. I originally thought of using 5448 because it was ISCSI-optimized but really like what the stacking provides in terms of inter-switch throughput and management. That said, can the 6248 be configured similarly so that is also ISCSI-optimized? My guess is yes but might take a little more config than the 5448. Is it simply just turning on jumbo-frames, flow-control, a bit of CoS, etc? Does anyone know the full list of "optimizations" and if so could list? Thanks in advance.
Also, in reference to a comment made by "Dell-Joe S" in this thread:
if you need STP use R-STP (MST) and portfast feature
turn off unicast storm control
use separate VLAN
QoS is not recommended by Dell and EqualLogic
iSCSI optimized switch do it automatically for EqualLogic Arrays and also provides some additional information about iSCSI traffic. I can't say about it in details, because I have no practice with PC55XX, but for me it looks like PR and advertisment.
