and how do you avoid single-point-of-failure?    if that COTS goes down, 
your storage is offline, and you've lost any writes in progress.

enterprise storage has fully redundant *everything*, a dual filer HA 
NetApp box will not even blink if any subsystem fails.    cached write 
data is mirrored in both controllers so if one controller croaks, the 
other can flush the buffers for it, and client storage connections 
continue without a hiccup.    yes, you pay for this.
