I would not purchase an NFS server from Network Appliances if I were
you. We made the mistake of buying one of their F540 boxes with
50GB of disk for approx $70K US. It has locked up so many times
this past week, we are regretting moving away from a sparc 20
with DiskSuite as a fileserver. They are overpriced, unreliable,
their support is non-existent. In short, they are one of the
worst investments you could possibly consider making. I will
agree that when the box is up and running, the performance
numbers are impressive as all hell...but balancing that against
having the box lock up 15 times a night (and when I say lock
up, I mean the box no longer responds to anything on the console,
you have to UNPLUG all the disks while they're spinning, and power
off the main controller, wait 30 seconds, and power it back on
again.) tends to make its numbers considerably less impressive.

True--but are you going to want your proxy to run on a box that
needs to be power cycled 15 times per night?

Another very good reason to stick with squid... :-)
