Policy Based Zoning on the 2.1 code level is pretty slick. The FC ports have to be set to “FC Switch Mode” and that makes connecting to an existing fabric problematic but possible. Setting the FC ports to “Compatibility Mode” is suggested against strongly. Not going to try it out since that is the case. But for direct attached SAN devices this is a great system. Brocade would do well to have some form of policy based zoning. Unfortunately “Policy Based Zoning” isn’t going to get along with Brocade Neighbors.
Zoning as a Policy in a “Service Profile Template” means only LUN masking on storage device has to be done! Not having to add zoning to two switches per “Service Profile” is quite the luxury.

Configuring Fibre Channel Zoning
If you have experience with this or have questions feel free to send me email in the contact section or comment this post.
Making it happen from the bottom up:
Fibre Channel uplink ports on Cisco UCS 6248 fabric interconnects
Set each FC port to be used as a “FC Storage Port” under equipment tab
Create VSAN’s under “Storage Cloud”. This will be a different location from the usual “SAN Cloud” if used to FC End-Host mode. This will be needed so the VSAN can be assigned to a “FC Storage Port”.
Assign VSAN’s to corresponding “FC Storage Port’s”
Create vHBA Templates
Create Storage Connection Policy. This is where the Policy Based Zoning happens. Here you set your Targets. Always go “Single Initiator Single Target” if you are cool.
Create SAN Connectivity Policy. Here you select vHBA’s and “Storage Connection Policy” for those vHBA’s. UCS will is smart enough to route the traffic corresponding to FIA and FIB to targets via vSAN.
Add Storage Connectivity Policy to Service Profile Template

Would be nice if each FC port could be set to End-Host or Switching mode. UCS’s with directly connected SAN devices and attached to a Brocade would be common if possible. For port cost a SAN switch between FI and several SAN storage devices and FC End Host mode is a must. That is why a mix or End Host an Switch Mode would be great. Cisco, make this happen! Overall this is officially a “Kick-Ass” feature.
