That doesn't suprise me.  Our "high end" arrays are Nexsans.  If the 
Promise arrays are pure crap, the Nexsans are only one step above crap.

The only difference between the Promise and the Nexsan is that the Nexsan 
doesn't crash quite as much and you can grow the size of the volumes.

So far the most fun thing I did to a Nexsan is to crash the web UI by 
polling it with Smokeping 5 times every 5 minutes.
