If the virtual disk that is hosted on the storage repo is too slow, you still have the option to use something like iSCSI for that. The performance penalty you get, when using the OCFS2 storage repos really is significant.
I do have achieved throughput of 90 MB/s on my SR inside my guests, but I do have dedicated storage for that (FC and iSCSI), so I can't state anything about the H700's performance. Note also, that I have benchmarked my OCFS2 SRs with fio, which you really should do first, since you won't get good performance it you've got a high-latency storage.
