• 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
