So, is there any 8 ports brocade switch that support fencing agent?
Pretty much all brocade switches are supported by the (included) fence_brocade agent.
can Qlogic switch work?
I think so. We have a fence_sanbox2 agent... not sure about all the models it supports - perhaps all, perhaps one. Help, anyone?
If I use a switch without fencing agent, can I use a manual fencing way to get system work?
Yes, but it will require manual intervention every time you have (or test) a failure.
In fact, what I want to study is the Symmetric lock principle, especially at the time concurrent write/read to the storage pool from both nodes, without considering one point failure.
If you had a third machine, you could use GNBD. The GNBD server would be a SPOF, but if it's just for testing, it would be fine. GNBD would turn your third box into a iSCSI-like device which has built in I/O fencing support.
