Guys,
I just purchased 2 CISCO WS-C2948G-GE-TX Switches. I was hoping to use these for iSCSI data for VM's.
Does anyone have any tips on what the best practice is for setting this up ?
or is this just plug and play ?
So just a separate vlan ?
Do i need anything else ? Does anything else need to be disabled ?
I'm hooking these up to a couple of C6100's gonna use them for testing.
Yep. When it comes to iSCSI not all switches are equal. That's why when you look at a lot of VMware reference architectures using iSCSI they use like Cisco Nexus 3K switches and not Catalyst.
Buffers all about buffers and a fast routing processer in the switch/router chassis.
This. You'd be surprised just how few network engineers understand this and throw 3560/3570's at enterprise production server/storage traffic.
Those hold up pretty well. Most people don't really push their server switches. IP storage can be different...especially in VDI when a boot storm happens. But yes... People forget there is a real difference between switches.
Another we see are things like 2960S switches connected to 10Gb storage. Those 10Gb ports are for uplinks, not something like storage. You very quickly overrun the buffers and performance goes through the floor.
Good luck with CatOS too!
