Hello,
I'm new to these forums, but I've done a lot of research on this topic with mixed results. Nobody seems to have done exactly what I'd like to do so I wanted to post a concept here and see what feedback others have. We had our core switch go down a few weeks ago, taking down everything including our SAN and VMWare servers. Luckily we didn't lose any data, but it was a scary and stressfull situation! I'd like to add in some redundancy (using DT) to at least keep our SAN and servers online in the event of a switch outage. We have two VMWare hosts, and two mirrored SAN nodes in two different buildings on campus, connected via fiber. I'd like to add in two additional switches, one in each location for a total of 4 switches (all running K software). Here is my whiteboard sketch with key:
VMW 1&2: VMWare host servers (HP ProLiant)
SAN 1&2: SAN node (HP StoreVirtual)
1-4: HP ProCurve switches (one 5406zl, and three 3500yls)
DT Links: Distributed Trunks
ISC: Interswitch Connect Links
KA: Keepalive Links
Everything will have two links (trunked) to each device (as indicated by the two lines). Am I on the right track here? TIA!
