On monday the Core Storage Fabric was extended from the ECS building to our second data center in the Public Policy building.
Two Qlogic SANbox 5200 switches are there and they were connected to our two switch clusters in ECS with two single mode fiber optic runs, one ran from the sw1/sw4 cluster in ECS B8 straight to sw5 in PP11 and the other was ran from sw2/sw3 in ECS H5 to sw6 in PP11 via the Physics building... so at least part of the way the fiber paths diverge.
This provides our fiber channel network an aggregate of 8Gb/s betwen ECS and PP (that's 4Gb/s each way) and an additional failover route.
Also, an additional switch was installed and actvated in ECS E2 for putting the Blackboard database and app servers onto the SAN.
With all these switch additions (those 3 switch additions consitituted a 75% growth) zoning is starting to get tricky. Documentation alone isn't going to cut it when it comes to management anymore. I'm looking at ESM apps to help with the management, as Qlogic's management app is not very whole-fabric centric.
