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

I dont follow - how do you want to share your fc storage over iscsi?
And what are these nodes? Storage nodes? Hypervisors?

And what are these nodes? Storage nodes? Hypervisors?
Nir
The initial idea was to share FC over IP network. All nodes are ovirt
nodes (hypervisors).
One node see the FC storage share as a block device. Take this block
device and share it over iscsi to node[2].
The node[2] will see the block device and create a new FC target to use
it itself...
I know, its science fiction...
After reading a bit on the subject another solution would be FCoE vn2vn
but this probably requires hardware.
Specific switches with DCB and FIP snooping which i don't have.
Any idea to extend FC to nodes without FC HBAs is welcome.

I still don't understand the problem you are trying to solve.
Can you explain the network topology?
- Do you have FC storage server, switch?
- How many nodes to do you have with FC HBA?
Do you want to add nodes without FC HBA, and you want to consume
the FC storage?
Or you want to add nodes with FC HBA, but you don't have an FC switch?

I have FC storage, FC switch and and with FC HBAs.
I want to add new nodes to the FC storage and to the ovirt datacenter
without using FC directly (no HBA, no switch).

We use FCoE in our setup. All the configs are in /etc/fcoe/ and fcoeadm is =
part of the ovirt-node iso. So this should work the same as setting up FCoE=
on CentOS or RHEL.

You need a NIC that supports it. We are currently using the Broadcom Corpor=

vendors sell a converged network adapter that should work.
