The sophisticated ARC/L2ARC is highly optimized and works on datablocks.
#OPENZFS SAN SOFTWARE FREE#
In addition to the ARC Read Cache that caches data in free RAM you can use SSDs as L2ARC cache. This improves write and general I/O performace. Small random writes are collected in a RAM write cache and transformed to large and fast sequential writes. Optionally you can add a highspeed dram (ZeusRAM) or SSD based logdevice (ZIL) to ensure secure writes without a performance degration. Secure sync write on filesystem level selectable to avoid dataloss on powerloss. Case (in)sensitive or mixed filesystems selectable. #OPENZFS SAN SOFTWARE WINDOWS#
Windows compatible NFS4 ACL with inheritance. Transparent compression without performance degrations due the LZ4 compressor and realtime deduplication. Management is done with reservations and quotas. 
Poolbased Storage Virtualisation with dynamically sized filesystems. This allows safe long term storages with ZFS. With redundancy all errors are repaired during read or on regular online scrubs. Always verified data with end to end checksums on OS Level on data and metadata. Nearly unlimited snapshots can be created without significant delay or initial space consumption due CopyOnWrite allowing revision safe storages. Data versioning with read-only snapshots. #OPENZFS SAN SOFTWARE OFFLINE#
Always consistent filesystems due CopyOnWrite (even on a crash during a write, no offline chkdsk needed). ZFS is designed for best of all data security and performance with hundreds od disks and Petabyte storage. No relevant limits regarding capacity, number of disks or filesystems or files or folders. Realtime replication of filesystems over the network. Modified datablocks are transferred based on snapshots. 
Network.with zfs send/ netcat in wirespeed with all relevant attributes
Blockbased highspeed filesystem replication locally or over the. Network virtualisation with Crossbow for virtual switches and virtual network adapters on vlans. Blockbased shares (MPIO, iSCSI, FC) either with the universal Comstar framework or as filesystem zvol property. (SAMBA is optional but does not support Windows SID as a file-attribute) Security id's (SID) as ZFS file attributes. Support for Windows ACL with Windows SMB groups and AD or Server based Level ACL, Snaps as Windows previous version and AD integration. Kernelbased SMB high performance server with Windows Share/File. Filebased sharing (AFP, FTP, NFS, SMB or WWW) as a filesystem property. Oracle from Illumos and included in OmniOS quite fast. With the commercial use for many years this results in a very stableĪnd sophisticated ZFS storage system. Solaris and free derivates like OmniOS are specialized and developed around ZFS for bootsystem and datapools. A napp-it ZFS Storageserver includes many features of expensive High-End storagesystems like realtime checksums on data and metadata with online scrubbing, CopyOnWrite with snaps and sophisticated readcaches in RAM and on SSDs (Hybridstorage).įeatures of napp-it (overview): Featuresheet.pdf
