We are "all in" with Brocade as our vendor to replace all of our HP switches. We are also replacing our ageing Fiber channel switches with Brocade's new 16GB ASIC models which will double or triple our storage throughput depending on what the host HBA we are replacing was running at. We are also using Brocade's BR 1860 converged HBA which is dual personality ethernet/FC so in addition to boosting the storage speed, I am also getting 10 GB ethernet.
We pitted them against Cisco (Cisco has a TRILL like technology) and price and support wise they were really not close. A lot came down to the price of the optics and the price of the hardened switches. We need 37 temperature hardened switches and Cisco's were $1K more expensive than Brocade. We could have looked at Juniper but we wanted the same manufacturer on the storage and IP side so it was down to Cisco and Brocade.
Brocade Virtual Cluster Switching 2-Minute Explainer - YouTube
Virtual cluster switching is pretty cool. In essence, it lifts the switching architecture from the FC side and lays it into the ethernet side. We bought 6 VCS capable switches for our datacenter core where our virtual hosts will be on the 10 GB fabric. We invested in 10 GB long range optics (10 KM) to go out to our DR site so our VM replication, backup, and failover SAN can be accessed more quickly. We are also bonding together, we have 8 fiber strands to our DR location, 2 16 GB FC links so the storage traffic has lots and lots of bandwidth for its replication.
Our IT Director was nervous about not using Cisco, but a $100K price difference helped change her mind. Plus, we learned that Lockheed Martin's internal IT dropped Cisco in favor of Brocade ethernet and FC with Juniper at the switching core.
