The software, designed to be used on a headless server-grade PC, sorts all your media (photos, music, etc), stores it centrally, provides remote access to the inside of the network and controls automated backups.
Home Server is available both as OEM software for build-your-own enthusiasts and system builders, or as part of a badging programme from partners including HP, Gateway et al.
No word on pricing yet. Charlie Kindel, GM of the Home Server product, said in a release that "It started with a vision that an always available device on the home network was an essential ingredient of a Microsoft platform for the home," building on the idea that many homes currently have more than one PC in them and that many more will enter that phase of techo-progression in the next five years.
The product is another example of Microsoft's desire to make everything available everywhere, with a central media store providing content to PCs, Zunes and Xbox 360s. The machine can be put in a suitably plumbed cupboard - the entire interface is accessible via the web, avoiding the need for a keyboard or monitor to be plugged in locally.
Beta testers have commented that the product is better than you might imagine, a sentiment echoed by early press previews. Will backup software and a network storage device become the must-have product this Chrimbo? Stranger things have happened. µ
