Whether you’re working in video and film, editing audio, or creating effects and motion graphics, take full advantage of the high performance of Xsan 2 from ingest and capture to final output.
Digitize with zero dropped frames
With Xsan, you’ll get the consistent, high-bandwidth drive performance that capturing video or audio data from tape to a digital storage system — the ingest or capture process — demands. Your SAN can accurately capture video or audio data from an ingest station (or multiple ingest stations) without frame drops.
Flexible editing
With Xsan, every editor on a project has concurrent access to source media files and never needs to transfer this data between stations. If your company lands another project, simply install Xsan on additional systems to let new editors use the SAN. Each Mac accesses shared files on the SAN as if the storage were directly attached. Thus, working from a SAN eliminates data duplication between systems and reduces your storage needs.
Effective storage
Xsan makes it easy for you to set storage policies and allocate different classes of storage to different purposes without forcing your editors to adhere to onerous rules. Affinities let you set up folders in a volume that direct files to specific storage devices. For example, a scratch data folder can direct files to RAID 0 storage, the finished works folder can direct files to RAID 1 storage, and a capture or ingest folder can direct data to RAID 5 storage for a good balance between speed and protection.
Simple solutions for complex networks
Xsan provides powerful SAN benefits with Apple ease of use. Xsan Admin helps you with storage area network setup, putting complex network topology in a simple graphical user interface. You can control access to sensitive files with user and group privileges, as well as set up usage quotas on a per-user or per-group basis. Xsan Admin will notify you via pager or email if a particular event occurs. Event notification options include the following: your capture/ingest or finishing station nears its storage quota, a controller failover occurs, a Fibre Channel connection fails, free space falls below a set percentage of available space, or a user or group exceeds its soft quota.
Working with bandwidth
Xsan lets you work well within the bandwidth required per video stream for the most common editing formats.

Simultaneous Final Cut Pro Streams Promise VTrak E-Class with Xsan 2
- Select your system:
Testing conducted by Apple in February 2008 using preproduction Promise VTrak E-Class units, preproduction Xsan 2, a shipping 3.0GHz 8-core Xserve metadata controller, and shipping 3.2 GHz 8-core Mac Pro clients. Testing was conducted using simultaneous unique 10-minute clips for each content type. Performance tests are conducted using specific computer systems and reflect the approximate performance of Promise VTrak E-Class and Xsan 2.
