Sun cluster setup question

I have 2 sun blade 1500 with Qlogic card and T3 storedge. I can connect to the T3 storedge through my boxes. Now I want to setup cluster, in order to setup I need to buy a Fiber Channel switch. Can I buy any fiber channel switch? Can you recommend some old switches? I can get it from ebay.

Thank You,
Mokkan

Brocade 300

It is pretty expensive. Is there any other switches which is suitable for this project? Does it need to be specific switch?

is Brocade SilkWorm 3800 fiber 16- port switch ok for it?

if this is a system for testing... you won't need a fc-switch or storage... you can use iscsi luns and a quorum server for example.

Thank you, It is not for testing actually. If all work fine, we will use it for some our development testing. Any fiber channel switch should work?
