We are using or have used McData 3232, McData i10k, and Cisco 9513 switches for zSeries Fiber Channel connectivity to our SAN storage. We have used these to communicate with EMC Clariion, DMX3, VMAX, and HDS TagmaStore disk subsystems.
Currently we are using the Cisco 9513 switches with EMC VMAX for the zLinux and z/VM disk LUN connectivity. We use NPIV and have some of the LUNs defined directly in the zLinux guests as FBA devices and others defined as EDEVs in z/VM which we then assign to the zLinux guests as minidisks. For ease of definition related to disaster recovery scenarios we have decided to migrate all of our servers over time to using the EDEV minidisks, knowing that there could be performance implications but our IO rates are low enough that we are not concerned. Just to clarify, there is no FICON involved in these connections as they are all Fiber Channel. The zSeries channels can be used for native FC or FICON connections. If you want to use NPIV, which I highly recommend, then you need to set the NPIV on for each LPAR where you are using it through the HMC with the channel offline to all LPARs.
