The new Sun file system ZFS represents a previously unseen breakthrough in file system performance and management. All HELIOS UB based products and tools have successfully passed performance and reliability testing using the new Sun ZFS file system. Important tasks like working with many small files and re-indexing the HELIOS Desktop database work many times faster compared to the standard UFS file system.
In addition, ZFS offers disk / file system / reliability features that are missing in other standard server operating systems. Our engineers are delighted and we feel that the latest Sun options like supporting AMD-CPUs, offering OpenSolaris on multiple platforms – and especially the new ZFS – bring unmatched performance benefits for customers. Sample ZFS performance. Jmp free version.
128-bit file system(s); no practical size limit. Transactional semantics (like journaling, disk is always consistent). Dynamic storage management.
Allows growing file system size. Allows adding disks. Allows striping and mirroring. No dedicated file system space reservation required, e.g. Two file systems can grow until ZFS pool is full. File system snapshot support. Allows backup of the frozen system without service interrupt.
Allows backup snapshots to allow easy access of older files, e.g. Snapshot at 10 a.m., 12 a.m., 2 p.m., 4 p.m., etc. Allows replicating a ZFS snapshot (e.g.
To a remote disk / server). Allows rolling back the file system to an older snapshot version. Snapshot cloning allows read-write access of a snapshot.
