|The newer units are actually quite a bit faster. Also, I highly recommend connecting your Coraids in a dual-network / not-cross-connected fashion.|
In other words, given machines A,B,C each with eth2 and eth3; switches Alpha and Beta; and Coraids Aleph and Beth each with internal connections Uno and Dos, that you connect them as follows. For switch Alpha, plug in A-eth2, B-eth2, C-eth2, Aleph-Uno, Beth-Uno. For switch Beta, plug-in A-eth3, B-eth3, C-eth3, Aleph-Dos, Beth-Dos. Do not cross-connect Alpha and Beta! In this configuration, with Jumbo frames, we get pretty good performance.
I've experimented with Quorum Disks and find that I quite like them, although we've just never needed them as we also fence with APC power bars. We use GFS extensively and it works quite well.
