If you can afford them, RAID boxes on a Windows 2003 or Mac OS-X server are the best solution for processing and compressing. Inexpensive RAID arrays can be built from scratch using 500 or 700gig drives in SATA configurations. If RAID is out of the question, individual firewire or external SATA drives can be used. We use a combination of RAID and Firewire 800 drives most of them home-built. We keep track of these drives and replace them after about 80% of their life expectancy has been used up. We backup to DVDs - which is cheap and more reliable than tape. Gigabit ethernet (already mentioned in the earlier messages) is a requirement. It is almost impossible to edit project files on a server without that speed. Having portable drives is very useful. We can download a project file from a server into a drive, so a faculty member can take it home over the weekend and work on the editing. We have done several projects in the past that contained more than 60 hours of video each. In each case we created designated server space that could be accessed from the digitizing computers as well as from the editing computers via gigabit ethernet. A high quality switch and a robust network are essential for this type of production. We have found the latest version of OS-X servers very useful for our needs. They are reasonably easy to operate and can be used simultaneously as file servers, web servers, streaming servers and much more sophisticated applications.
