Price it out carefully; but remember, the more expensive netapp/emc
will be a lot more reliable, however, if it works for your application,
just building 2 yourself (and keeping one spare) is quite often a lot
cheaper. Do a nightly rsync, and you are ready for most disasters
with a half-day rollback worst-case. Of course, if restoring from
your last backup is millions of dollars of lost profits, you might
want to go with the emc/netapp- but if restoring from your last backup
is more like a couple thousand (or even a couple tens of thousands
of dollars) building one yourself with one in reserve and a good
(tested!) backup setup may be the best solution.
The other thing to consider is just engineering your application so that it
stores the data on local disks; In terms of hardware (rather than engineering
time) the cheapest (and probably highest performance) solution would be
to just put one or two local disks internal to each computer, and have
your application distribute the data in a redundant fashon... of course,
depending on your application, this can be a lot of work- but if you
have more Engineering power than dollars, you can get a good deal this way.
