Ethernet over Fibre Channel
Posted on 2013-05-27
Not FCoE... ethernet over fibre channel.
I have two geographically separate sites... they're quite happily connected by fibre.
At present, I have FC GBICs plugged into Cisco Catalyst switches on either side, and it essentially gives me one big LAN.
The SAN at each site is FC, and I do application-based replication across this WAN from production to DR (ethernet based communication).
I just had a realization, but it may be one of those "no that's dumb" ideas. I've not tried it, and testing it would involve disconnecting about 100 users from internet and production services... so not a good idea without a maintenance window.
Could I connect my Catalyst ethernet switches to the SAN fabric, connect the fibre between the sites to the fabric, maintaining my multi-site LAN and gaining one big multi-site SAN?
In case it matters, they're HP SAN Switches (Broacade Silkworm 200e).
