[ovirt-users] integrate iSCSI and FC on the same oVirt datacenter

Hi,

Not sure if this is the right place to ask but maybe someone can provide 
directions for my problem.

I have a full FC setup with FC switch and FC HBAs on Linux (Centos) to 
access my storage.

However we cannot afford expanding our FC infrastructure thus making it 
hard for us to add more nodes in the oVirt setup.
FCoE requires compatible switches and adapters (correct?) which is also 
out of budget.
Our storage supports only FC.

I thought something like this might work:

node[1]: FC - ISCSI <-> node[2]: ISCSI - FC

share the FC block device over iscsi and then create a new FC 
target+initiator on the new node with same FC lun as the original?

Could this work? How? Other ideas?

regards,

Giannis
ps.
a) a solution would also be to migrate completely to iSCSI but I'm 
trying to avoid that atm.
b) another one would be to create a second datacenter for iSCSI but also 
trying to avoid that if I can
