   The NS6000 at SkyCache was supported.  By me.  Worked great.  It had 
a few problems here and there, and I fixed them.

   Despite the very well-trained nature of techs in our industry when it 
comes to buying overpriced, unnecessary "support" contracts, there's 
really nothing magical about vendor support...except for the fact that 
they care about the data on my machines a lot less than I do.

   The previous-generation NS6000 took 23GB drives with no problem, and 
the NS7000 does as well.  These machines are well-designed with very 
few artificial limits.  It will Just Work.

   Not even close.  Don't underestimate the power of hardware-assisted 
RAID, dedicated processors for RAID parity, dedicated processors for 
UDP checksums and XDR encoding, hardware-assisted.  PC toyz won't be 
able to touch that, unless you spend almost as much as you paid for 
those Auspex boxes.

   It's really a matter of how serious you are about performance and
