How can the total amount of port buffer memory be determined for Cisco switches?
Cisco doesn't seem to publish this data anywhere as part of the hardware specifications, but the information seems crucial for determining whether or not a switch is adequate for iSCSI SAN traffic.
I see various values shown in the output of the show buffers
command, but I'm not quite understanding how to turn this into usable data for comparing switches.
I'm particularly interested in comparing the Catalyst 2960 and 3750 models, specifically to help deter someone from using an inadequate switch for iSCSI traffic. Any thoughts on other factors that play into switch usability are welcomed, though I'm particularly interested in port buffer space data here.
