This question relates to brocade fibre channel switches and Fabric OS.
I've got 16 blade servers, each with 2 HBAs. On each server, HBA1 connects to fibre channel switch1 and HBA2 to fibre channel switch 2. The storage array has 2 storage processors (SPs), and each switch is connected to both SP, so fibre channel switch 1 connects to SPA and SPB and fibre channel switch 2 also connects to SPA and SPB. Therefore servers have 4 paths to each LUN.
I need to add 2 new fibre channel switches in between the storage array and the existing switches so lets call these fibre channel switch 3 and 4 in order to give some more servers access to the storage array.
So currently we have this:
Storage array > Fibre Channel switch 1 > Blade server
and I am looking at doing this:
Storage array > Fibre Channel switch 3 > Fibre Channel switch 1 > Blade server
I would then connect new servers to the storage array via fibre channel switch 3 and 4. My question is if I want to connect two ports on switch 3 to two ports on switch 1 to create a trunk group (i.e. to increase the available bandwidth between the two switches), is there any additional configuration I need to put in place or would this happen automatically so long as I set up the zoning correctly? Also would I need any additional licences for this?
I hope I've described the current set up and proposed change clearly, but if not please let me know and I can add clarifications.
Many thanks for any help
