Steve C,
You have a “people” problem, not a technical problem.
We operate 2 X-SAN systems with almost one hundred seats. They ALL are connected to the internet. While I understand the “island” approach of your IT person, I personally believe that his position is outdated and myopic. So many programs now rely on the internet for updates, authentication, etc. that we could NOT function easily without web access. And.. of course, there’s your original point about moving files.
As the IT world and Post production world are forced to interact, you’re going to see many more of these kinds of discussions. We’ve adopted a “mutual education” approach between post and IT. I teach them about timecode, video codecs, and FCP quirks, and they teach me about TCP, SMB, and DNS. The fact is that we can NOT exist without each other. Our X-SAN uses their ethernet switches for our “private network”, and of course, has to go through their system for internet access.
My best advice is to take your IT guy out to lunch, and have a heart to heart about this situation. Our world has definitely changed… and now so is his. He’s got to adapt too.
Good luck.
Mark
