the problem with an appliance (which concept I actually like... it pushes
clusters to the masses) is the interaction with the IT support organizations..
If it's perceived as a piece of IT infrastructure or equipment, they're
going to want to manage it, and if it's at all unusual, then they're going
to either resist, or charge you a bunch for handling the anomaly. Or,
they'll wash their hands of you, and require that YOU manage it and take
full responsibility (and most likely, not allow you to interconnect to the
rest of the corporation).
If it hangs on the network, then the corporate network security folks are
going to want to have a warm and fuzzy feeling that it's secure and not
going to be a portal or tunnel for attack. That generally means having
some form of automated patch management, etc., which gets you back to
having to deal with the IT support organization.
If you're contemplating going it alone, and self supporting, the corporate
governance and audit folks might also throw an oar in. After all the data
you're processing on that beast is probably "internal distribution only"
potentially being trade secret or even worse, containing "Personally
identifiable information", in which case they're going to want to
understand how you are controlling the data and making sure that
confidential data stays confidential AND that you don't inadvertently
violate someone else's data rights.
And, then, you still have the interoperability of data products..
(although, I think that one is the most solvable.. it's a matter of file
formats, mostly).. trying to paste the output of gnuplot into ppt.
If you have a MS based cluster, then dealing with the IT management folks
and the network security folks becomes orders of magnitude easier (and
potentially cheaper). All the icky problems of network and data security
have already been solved (at least to the satisfaction of the organization).
