Hi, regarding nova, I am not clear about fiber channel over ethernet functionality, if it is necessary to configure something more for fiber channel over ethernet on the compute side (we already configured fcoe utils, lldpd, etc),
 
Doubt:
In the compute node have to be installed cinder-volume and nova-compute?
For everything to work ok.

In our use example we use Dell SC4020 works:
For example with:

Installed cinder volume:
...
Default_volume_type = dellfc
Enabled_backends = dellfc
[Dellfc]
Volume_backend_name = dellfc
Volume_driver = cinder.volume.drivers.dell.dell_storagecenter_fc.DellStorageCenterFCDriver
.....

In the compute node we use nova-compute and cinder-volume to connect to the storage and it works OK with FC, with FCOE we are not yet using it because we are trying to solve the BCM57810 CNA functionality with Linux to be able to use DCB it does not work).

Using nfs, zfs, gluster, we use a dedicated volume cinder node, and it works fine. The doubt arises FCOE.

I would appreciate if someone has a similar configuration and tell us the experience.

Thank you
