Apple releases Xsan 2

Apple today announced Xsan 2, a brand-new edition of its popular Storage Area Network (SAN) software.

SAN software allows you to manage storage devices on a network. It manages the reading and writing to the volumes through one machine (a server), otherwise data corruption can occur if two machines are reading and writing to the same area at once. It also allows you to control access to the data on these volumes. It is commonly used for managing video editing storage networks (we use Xsan 1.4 here at Digital Rebellion) so while it's probably not particularly exciting for most people, it is a big deal.

New features include a completely overhauled Xsan Admin (yay) which offers greater speed, greater stability and more monitoring features. There is now an Easy Setup wizard, a new filesystem offering up to 2 PB per volume (1 petabyte = 1024 terrabytes), and templates that optimize the system for a particular task (e.g. HD video, SD video, file sharing, etc).

There's also a new MultiSAN feature that allows you to connect to other SANs on the same server, such as a SAN for dailies and a different one for stock footage for example. It also comes with Spotlight support.

My number one favorite feature though would have to be the ability to direct files to a specific location. You can automatically set certain types of files to go to certain volumes such as dailies in one place, audio in another, project files in a third. This is very cool and is a great way to keep everything organized without having to impose rules on everyone.

I am very much liking the sound of this. My major complaint about Xsan 1.4 (and the same goes for Color and Shake) is that it didn't feel very Apple-like. It was complex to set up, it didn't "just work" and it was difficult to manage. Apple is famous for its ease of use but it was lacking in the previous version of Xsan.

I would be upgrading in the near future were it not for the following caveat: it is Leopard-only. The system requirements for the server are much higher too - 2 GB RAM minimum, plus 2 GB per volume (up from 512 MB per volume). I would not advise the use of Leopard in a critical environment yet. Some people edit on Leopard and have no problems at all but I am waiting until at least 10.5.4 before I consider upgrading.

Despite this, this is a great upgrade. Xsan 2 is available now for $999 per machine.
