The managed flash software seems very interesting. I think that SSDs are the next evolution for storage. From a physics perspective, I'm not sure how much more can be done to improve mechanical disks. But right now, it's hardly affordable and because of the life time of the more affordable MLC variety, I have questions about reliability and MTBF.
I think that RDMA would be awesome, but RDMA is going to be for IB and right now, there are some innovative things that can be done to improve iSCSI performance over native IP/Ethernet.
If you have access to this white paper, it talks about a different caching strategy to improve performance of iSCSI by 58 to 70ish percent. I'd like to see some innovation along these lines...
