Software Update: Apple Xsan 1.4.1 Filesystem and Admin


This one is for the enterprise, pro video and pro audio readers out there. I'd be mighty surprised if any of you had a SAN setup in your living rooms, as appealing as that may be! Xsan is Apple's high-performance SAN file system for Mac OS X and Mac OS X Server. It's super fast and high in Fibre.

Apple has released an Xsan 1.4.1 Admin Update, as well as an Xsan 1.4.1 Filesystem Update. Both updates include performance tweaks and improved reliability. From the Read Me:

The Xsan 1.4.1 Admin update includes fixes for:

- labeling and initializing Fibre Channel LUNs larger than 2TB in size
- expanding storage pools and volumes
- working with multiple Xsan metadata controllers in a heterogeneous environment
- displaying progress messages while performing lengthy operations
- preventing custom configuration changes from being overwritten during a save
- accurately reporting Fibre Channel multipathing errors

The Xsan 1.4.1 Filesystem update includes specific fixes for:

- metadata controller failovers during power outages and network disconnects
- memory related errors that can result in slow system performance or hangs
- reducing fragmentation of large files and frame drops during ingest
- preventing file system metadata corruption
- hosting Xsan volumes on Intel-based metadata controllers
- defragmenting files after a volume bandwidth expansion
- compatibility with Apple and third party applications
