Do you have it running?  If so, how many nodes (targets) do you
have connected?  If you have it running in redundant mode, have you
measured the performance difference between RAID0 and RAID5?

It's now called Rapidscale.  I heard that when they were bought out by 
Rackable, they had a name conflict in the US and had to change it.
