There’s a product out there called SANFusion that can allow Media Composer to read disk images on Xsan as though each were a separate workspace in AvidFS. This allows environments to leverage existing pools of storage sitting on Xsan as though they were sitting on an Isis or a Terablock. Check it out at SANFusion:
SAN Fusion is an easy and cost-effective solution that allows you to use Avid Media Composer with your existing Xsan infrastructure.
By using an existing Xsan volume as a backing-store for SAN Fusion’s virtualized workspaces, editors can experience authentic Unity-style bin sharing and locking from within Media Composer 5.5.3 or later. Unlike other solutions that purport to make Avid work with Xsan, SAN Fusion is a client-side application with no additional server or minimum number of seats to buy.
SAN Fusion clients mount and unmount workspaces on demand through our intuitive GUI to provide Media Composer a real-time translation layer between it and Apple’s Xsan filesystem. The end result is the best of both worlds: Avid’s first class bin and media sharing combined with Apple’s storage-agnostic low (or no) cost cluster filesystem.
The $1,500 price tag shouldn’t scare you off. Just compare the cost of a Promise X30 to the same amount of storage from Avid and you’ll get the idea why. And if you need any help with such things, give us a shout at email@example.com.
