Hi,
There are no such systems available commercially as far as I am aware.
I developed a custom solution for my company to achieve this but at
this point in time your best bet is a SAN that support SRP. Have a
look at the devices from Scalable Informatics - I always recommend
them to others using Infiniband fabrics.
