Hey Nux, Something like ScaleIO might fit your use case (there is a community version as well the commercial version owned by EMC now) We've had a couple of customers who swear by it for awesome performance.

Hi Lucian, What is your use case for this project, and what are your concerns around network limiting your storage speed? If you put a storage front end server (NFS, iSCSI) on top of the DAS and link up with 10gig networking you should get decent performance - there’s plenty of large scale production environments using IP based storage. Personally I’ve ran XenServer with an iSCSI backend over 10gig in the past and even during ACS boot storms never managed to push the network links past 20-30% utilisation.
