Windows Storage Server 2008

Single instance Storage

Among the additional storage-centric capabilities provided in Windows Storage Server (WSS) appliances over a traditional Windows Server is file deduplication through Single Instance Storage (SIS). SIS delivers built-in file de-duplication to optimize storage capacity by actively comparing and eliminating identical files on file sharing volumes. Duplicate files are transparently replaced with file system links to the single copy retained in the SIS Common Store -- saving significant amounts of capacity. As a result, file serving performance is improved because more files can be cached by the operating system. In addition, protection and recovery by SIS-aware backup solutions can significantly reduce backup windows and recovery times.

Optimizes Storage Capacity

Single Instance Storage (SIS) provides data deduplication for Windows File Services. It can significantly impact the amount storage consumed within an organization. It’s not uncommon to recover between 25-40% of existing disk space once the file consolidation has completed. Easy-to-use tools and a transparent operation means the technology is relatively easy to use and requires very little maintenance.

Improves File Server Performance

SIS minimizes the amount of physical data allowing for quicker backups and recoveries. Loads from file caching and file accesses are reduced and everything operates without users even being aware that many of their files are centrally stored.
