I'm a developer/SQL type person that has inherited an iSCSI SAN/Vmware setup in the past year. HP Lefthand P4500 SAN. Single iSCSI switch - HP Procurve 2810. Dell Equallogic PS6010E 10gb SAN (not used yet.) About 60 VMs on 4 HP DL380 G8 hosts with 96gb memory each.
The 2810 was upgraded to dual Dell Powerconnect 6248 1gb switches - LAGged together. We have dual Dell Powerconnect 8231f 10gb switches to add to the mix, which will also be LAGged together, and then each LAGged to one of the 6248's each, to form a 4-switch circle in one iSCSI subnet that provides both 1gb and 10gb options for storage and hosts.
Is there a good app I can use to understand what's going on overall on those 4 switches - a visual dashboard, and a way to drill down into it for problems? I'm comfortable with Wireshark for looking at things, and command line stuff, but looking for a way to get a higher level view of this setup and what's going on with it in a less detailed way, but a way that will help show if it's having problems that require me to look deeper.
