High Availability
Xsan is a 64-bit cluster file system that provides concurrent data access over high-speed Fibre Channel to multiple systems on the network. For better performance and higher availability, you can pool storage across multiple RAID devices, and each Xsan client can use this centralised data as if it were directly connected.
Support for 2PB files and volumes
Xsan lets your users share multiple files and volumes; each can be as large as 2 petabytes, or more than 3 months’ worth of uncompressed 1080i high-definition (HD) video at 30 frames per second. Xsan supports billions of files per volume, with each metadata controller hosting multiple volumes at the same time.
File sharing over Fibre Channel
Xsan storage networking eliminates the bottlenecks of traditional network file servers that use Gigabit Ethernet and that are not fast enough to transfer dense formats such as HD video. Fibre Channel gives you a 4Gb-per-port connection for increased data transfer and can be used with Fibre Channel multipathing for greater aggregate throughput. This is perfect for multiple editors working on a video project or a compute cluster that needs fast data access for maximum utilisation of processing power.
File-level locking
Fine-grained file-level locking enables simultaneous access to shared files. All clients can access all the files on the volume, but only the client that has read/write privileges can edit a locked file. This contrasts with volume-level locking, which enables only one computer at a time to write to an entire volume. File-level locking provides enormous productivity advantages in post-production workflows where multiple editors are using a single large file.
File system access controls
Xsan supports flexible file permissions that not only work with Mac clients, but are fully compatible with Windows Server, Windows Vista and Windows XP. With file system ACLs, any file object can be assigned multiple users and groups, including groups within groups. Each file object can also be assigned both allow and deny permissions, as well as a granular set of permissions for administrative control, read, write and delete operations. For added security, Xsan supports a file permission inheritance model, ensuring that user permissions are inherited when files are moved to the SAN and rewritten when files are copied to the SAN.
