The most powerful way available to quickly and automatically configure a replication and disaster recovery solution in just minutes! There’s no complex scripting, no training manuals or courses, and first-time setup is absolutely fool-proof.
Replication is configured between two SoftNAS Cloud Enterprise controllers – the “source” and the “target” nodes – which are configured with just a few mouse clicks. It’s so easy because of the 4-step wizard – just fill in a few blanks and setup takes place automatically.

Scales to handle millions of files efficiently.

Unlike clustered filesystems, SNAP HA uses block replication, which only sends the changed data blocks across the wire from source to target. There’s never a need to do wasteful, resource-intensive file comparisons, since anytime a file’s contents get updated, the copy-on-write filesystem keeps track of which data blocks have changed and only sends the changed blocks between two snapshot markers in time (once per minute).

No training required, normal operation is fully automatic.

SNAP HA relationships are quickly and easily created for disaster recovery, real-time backup and failover – ensuring your data is fully-protected at an off-site location or on another server or VM; e.g., at another data center, a different building or elsewhere in the cloud. SoftNAS Cloud Enterprise streamlines the entire replication setup process, making it fool-proof, quick and easy enough for anyone to do without training in less than a minute. Block replication occurs once each minute, transmitting only the latest data changes from the source to the target node. If an unrecoverable failure occurs in the source node, the target node is ready to take over.

Storage Pools

Aggregates of storage available for provisioning.

Storage pools are groups of disk drives that are aggregated together into “chunks” of disk space. A storage pool is built from physical and virtual disk storage. A pool is comprised of one or more RAID groups of disks. These disk aggregates are pools of storage available for allocating Volumes, File Systems and LUNs.
When additional disk capacity is needed, an existing storage pool can be readily extended with additional RAID arrays or creating new storage pools.
Optionally, SSD read cache and write log cache devices may be added to a storage pool to boost performance. Pools can be imported for moving storage from one instance or VM to another. Hot spares can be assigned to a pool, and ready in case of a device failure.
Pool scrubs scan the entire pool, detecting and automatically correcting any data errors due to bad sectors, bit rot or other errors that can slowly creep into storage media over time. Bad data blocks are detected by comparing to block checksums. Erroneous blocks are repaired using RAID redundancy.
Devices can be taken offline, replaced and new devices can be placed online to resolve RAID arrays that can become degraded over time due to device failures. These online operations ensure the storage pool does not go offline and continues to serve production data, even when a device has failed.

Flexible Volumes and LUNs

Flexible storage allocation.

Click to enlarge

Storage space is allocated from storage pools and assigned to volumes. A volume can be shared as a file systems or LUN (block devices for iSCSI targets).
An unlimited number of filesystem volumes and block device LUNs are supported.
Volumes can be thick or thin-provisioned.
Each volume can be assigned a snapshot schedule. An unlimited number of snapshots may be taken for each volume.

Storage Thin-Provisioning

Allocate storage space where it’s needed most.

Thin-provisioning automatically allocates storage space from storage pools as it is needed. Thin-provisioned volumes allow a single storage pool to provide storage to any number of volumes, so that an administrator can focus on managing pool space instead of available space for each separate volume.

Raid Array Disk Aggregates

Increased data integrity and performance

RAID (redundant array of independent disks) combines multiple disk drive components into a logical unit, to provide redundancy and increased disk performance. On Amazon EC2, EBS volumes are organized into RAID arrays.
RAID also enables you to “hot-swap” replace failed disk devices with the storage system online and uninterrupted. Hot spare devices can be set aside, ready to be put into immediate use when required.
All common RAID levels are supported, including RAID 0, RAID 1, RAID 5, RAID 6 and variations such as RAID 10. It’s easy to select and configure the RAID level that’s best for achieving the balance of performance and availability, including setting aside “hot spare” disks for rapid recovery in case of a disk failure.
Both hardware RAID and software RAID options are available, providing a full spectrum of options for protecting your data.

NFS File Sharing Services

SoftNAS Cloud Enterprise NFS provides Linux servers and NFS clients with the most powerful NFS server available.

NFS v3 and v4 are supported, including the full range of NFS export security and other options.
NFS and TCP have been tuned for optimal performance. The SoftNAS Cloud Enterprise NFS Server has been tuned and optimized for maximum throughput and performance, so web application servers and other NFS clients operate at maximum speed.
NFS filesystem snapshots, clones, caching, compression, deduplication and more. Underlying NFS data storage is managed by ZFS, extending snapshots, cloning, multi-tier caching, data compression, deduplication and other ZFS features to NFS.
Linux user and group identities can be mapped using standard Linux-based identity management, so NFS file and directory ownership and permissions operate as expected.

Linux user, group permissions and flexible authentication support. Security restrictions can be used to restrict NFS client access by host and IP address range, and using any Linux-supported authentication method.

NFS Firewall Support. NFS is configured to readily support traversal through static firewall ports, providing both convenience of configuration and increased network security and access control.

Windows File Sharing / CIFS

The SoftNAS Cloud Enterprise CIFS provides the advanced features of ZFS combined with the proven, flexible Samba server.

Click to enlarge
Windows file sharing via CIFS protocol provides file sharing with Windows servers and Windows clients including Windows 7/8, Windows XP and other Windows-compatible devices. An unlimited number of file shares are supported.
Samba can be configured to authenticate using Active Directory user accounts, and Windows users and groups can be mapped to Linux users and groups. Flexible access controls can be configured on a per share basis.
Underlying Samba filesystem storage is managed by ZFS, extending snapshots, cloning, multi-tier caching, data compression, deduplication and other ZFS features to CIFS shares.

iSCSI Targets Server

The SoftNAS Cloud Enterprise iSCSI Server provides advanced block level storage management with iSCSI targets and flexible LUN support.

High-performance iSCSI Server.  iSCSI Server has been optimized for maximum throughput and minimum CPU overhead. iSCSI benefits from multi-tier read caching, as well as write-cache options to boost write IOPS.
Thin-provisioned LUNs. LUNs can be thin-provisioned with “sparse LUN” allocation. Since the ZFS copy-on-write filesystem is used to manage thin-provisioned LUNs, there are no performance penalties for thin-provisioning.
LUN snapshots, clones, caching, compression and more.  Underlying iSCSI LUN storage is managed by ZFS, extending snapshots, cloning, multi-tier caching, data compression, deduplication and other ZFS features to all iSCSI targets.

Multi-Tier Caching

High-Performance RAM and SSD Caching. RAID 10 with RAM caching increases read performance up to 10,000 IOPS on Amazon EC2. Second level SSD caching can increase read performance to 50,000 or more IOPS to support database and other I/O intensive applications.

Click to enlarge
High-speed RAM Cache. RAM is automatically used as a high-speed cache. The RAM cache is comprised of ZFS Adaptive Replacement Cache (ARC), a page replacement algorithm with better performance than LRU (least recently used).
Second Level SSD Cache. A second level read cache (L2ARC) can optionally be configured with hundreds of GB of high-speed SSD or even local ephemeral disks to increase the local read cache.
High-speed SSD Write Cache. Write caching is also optionally available. Write caching is comprised of the “ZIL”, the ZFS Intent Log. A mirrored pair of high-speed SSD drives can be assigned as a write log or ZIL. The ZIL absorbs bursts or steady streams of incoming, synchronous write operations by rapidly recording the writes in high-speed, mirrored SSD storage, then returning quickly to the caller. This makes synchronous writes to NFS, iSCSI or CIFS operate at maximum speed.
Later, when there is less I/O overhead, the writes which are cached in the ZIL are written to long-term pool storage; e.g., to a RAID 10 array of EBS volumes using provisioned IOPS for maximum throughput and I/O.


SoftNAS Cloud Enterprise includes inline block deduplication, which identifies and eliminates duplicate data, increasing storage density and efficiency.

Deduplication is the process of eliminating duplicate copies of data blocks are checksummed using a hash function that uniquely identifies data.
When new data arrives with the same checksum hash value as a previously deduplicated data block, no data is written and the block’s reference count is simply incremented instead.
Deduplication is useful when data is known to have a large amount of duplicates; e.g., multiple backups of the same file servers, copies of data being shared but only slightly modified by multiple users, etc.

Save disk space and increase performance by compressing data for maximum efficiency.

Increase data storage efficiency. Compression can save between 20% to 90% disk space that would otherwise be required to store your data.
Increase Performance and Throughput. Compression not only saves space, but also improves performance by reducing read and write I/O. This is because the time required to compress and decompress the data is quicker than the time it takes to read and write the uncompressed data to disk. In addition, the system can manage even more compressed data in cache, so compression enables effective caching of more data, which increases performance even further.

Copy On Write Filesystem

The copy-on-write filesystem built into SoftNAS Cloud Enterprise ensures that data is always consistent on disk using a number of techniques, including copy-on-write.

SoftNAS Cloud Enterprise never overwrites data in place. What this means is that when data is changed, it is always written to a new block and checksummed before pointers to the data are changed. This eliminates the potential for data corruption due to inconsistency or failures during write operations.
Data blocks containing active data are never overwritten in place, and a new block is allocated before modified data is written to it, then any metadata blocks referencing it are similarly read, reallocated, and written. The copy-on-write process ensures data and metadata is always consistent on disk.
The old data may also be retained, creating snapshots of the file system through time as changes are made.

Scheduled Storage Snapshots

Snapshots preserve an image of a volume or filesystem at points in time, providing numerous recovery points without performance impacts.

Click to enlarge
Ability to recover to any recent point in time. Snapshot data is delayed from being permanently deleted from disk storage until the last snapshot in which that data exists finally expires. Snapshots are nearly instantaneous and consume no additional disk space within the pool.
However, as data within the active pool’s dataset changes, the snapshot consumes disk space by continuing to reference the old data blocks, thus preventing that disk space from being freed until all its references are deleted; i.e., the snapshots are deleted or pruned.
Unlimited scheduled snapshots with automatic pruning. Snapshots are automatically created and maintained on a scheduled basis. By default, SoftNAS Cloud Enterprise keeps 3-hour snapshots for the current business day starting from 6 a.m. to 6 p.m., plus 5 days of daily snapshots at midnight. This means you can go back in time and recover files and data most anytime. And unlike other systems, which limit the number of total snapshots you can have, with SoftNAS Cloud Enterprise, you can have an unlimited number of snapshots. An unlimited number of pre-defined snapshot schedules or custom schedules may be used. Snapshots beyond the user-configured retention period are automatically pruned.
Recover instantly, with confidence – without a backup restore. Snapshots provide the ability to instantly recover to any point in time for which a snapshot exists. You can roll back in time to recover files that were accidentally deleted, restore a file system prior to a data corruption event and quickly restore files that were accidentally deleted – without the time, storage space and hassles associated with restoring from a backup.

Writable File System Clones

File system clones provide a proven means of rapid recovery from virtually any kind of data corruption or deletion event.

File system clones are writable copies of your volume or file system created instantly from a storage snapshot.
Snapshot clones become writable copies of your volume or file system from an earlier snapshot, whose initial contents are the same as the snapshot from which it was created. These cloned copies take up no appreciable disk space and allow you to go back in time to retrieve data from past snapshots.
As with snapshots, creating a clone is nearly instantaneous and initially consumes no additional disk space. You can even modify the cloned copies as much as you want. When you are done using the snapshot clones, they can be safely deleted without affecting any other data.

Automatic Error Correction

Data integrity is designed into SoftNAS Cloud Enterprise – protecting data integrity 24 x 7 x 365.

Maximum protection for your business information and data.
SoftNAS Cloud Enterprise automatically detects and corrects unforeseeable data errors that arise from bad sectors, invisible “bit rot”, disk media deterioration over time caused my magnetism decay and cosmic ray effects, and other sporadic issues that can cause data storage or retrieval errors.
Proven ZFS data integrity measures have been implemented by SoftNAS Cloud Enterprise to detect errors, repair them automatically and ensure data integrity is maintained. Each read is validated vs. a 256-bit checksum code. When errors are detected, the system automatically repairs the block with the corrected data.
Periodic data scrubbing detects and corrects errors before it’s too late.
Data integrity scrub operations are also available to periodically traverse an entire storage pool, read every data block, validates it against its 256-bit checksum code, and repairs the block if any errors are detected. All this happens while the storage system is live and in production use – there is no downtime required. Data integrity scans can be triggered to run in the background during off-peak hours. Scrubs can be manually initiated, or optionally scheduled to run periodically as a cron task.
