Camera original formats will maintain the most quality, but they are also often partially proprietary (even if they lean heavily on on the MXF standards, there always seems to be some proprietary extras mixed into the files on formats like XDCAM and P2). In all likelihood the essence video in these MXF camera formats will be playable long into the future owing to the MPEG codecs they employ. You need to be a little more cautious if you are dealing with strictly proprietary codecs like ProRes or DNxHD. These formats could one day become open standards, but only by the graces of Apple or Avid, respectively.
Unfortunately the nature of all file based content is relatively ephemeral since codecs change and improve over time. Then you compound that with how computer filesystems change and improve over time as well. Realistically, you can’t expect to encode some video to a contemporary codec and have that be a common codec a couple decades from now. You’re confronting an issue the industry is still at the beginning of trying to solve, so I recommend storing the camera original data along with perhaps an H.264 high bitrate proxy, but there are no guarantees.
The safest physical layer for the data would be an open-format LTO (the open formats for LTO being TAR and LTFS).

[David Roth Weiss] “Yes, someone did. One of our Creative Cow members said it as a joke, because today is his birthday and he said he “wants nothing more for his birthday.” That’s how rumors get started…”
I should have said “No one from Apple”. Random guesses from COW users should not be given the same weight!

Most likely you will need the same software, unless the LTOs were written with standard TAR (Cache-A does this by default) or the new LTFS (which, as far as I know, has been added as an option by both Tolis and Cache-A for LTO-5 setups). Almost anything else will require the same software that wrote the tape to read the tape. Check with individual vendors to know for sure.

No one ever said June 9th. At the February private event it is said Apple said “this Spring”, which technically gives them till 6/20. Then at the SuperMeet they said “June”. So I’d go by the more recent projection and look for a release the last few days of June. If we make it to July with no release, then it could be considered delayed.

Well you still need the HBA and the fibre channel switch, but for a small Xsan you could use a little Qlogic 1400 and I’m holding out hope there will be a sub-$1,000 Thunderbolt fibre channel HBA to go with this.
But dropping the $999 Xsan tax helps a lot!

Strike that, I confirmed with one of my little birdies in Apple- Xsan client is included at no additional cost with Lion. $29 buys you the OS and the Xsan client license. $50 buys Lion Server with Xsan Admin license.
Now we need to see what the Thunderbolt fibre adapters are going to cost….

Thanks, Steve! I figured you’d have the dirt on that one.

Good point made in the Xsan forum- does “built-in” necessarily mean “no additional charge”? I suspect it does, but we’ll see in July…

Great info – thanks Steve. I had no idea TCP had that much of a computational overhead. Are there ways to reduce it and speed up 10GigE to get it closer to its 10Gbs ceiling?
“Aside: has TOE ever been attempted on OS X? I know on Linux it requires kernel extensions as well as drivers…
