The SnapServer DX2 is a high performance, scalable NAS server; and the first storage system in its space that you do not have to provision. With DynamicRAID, hard drives can be added or replaced at any time to grow existing storage pools. Volumes grow automatically as drives are added, simplifying the management and reducing the time required to adapt to changing storage requirements.

Ideal for storing both block and file data. This 2U 12-bay SnapServer DX2 storage array supports up to 12 SATA, SAS, or SSD hard drives and integrates out of the box with Windows, Linux, UNIX and Macintosh environments. Consolidate multiple servers into the SnapServer using the data import tool, or host virtual servers and database applications utilizing the iSCSI SAN feature. The SnapServer DX2 supports Microsoft VSS/VDS integration to simplify management and ensure application consistent snapshots. For data protection, the SnapServer DX2 has the ability to replicate to one or multiple SnapServers, take snapshots for point-in-time recovery, and perform backups to disk, VTL, or tape.

With the ability to scale up to 384TB with seven SnapExpansion chassis, the SnapServer DX2 enables you to create a customized storage server with simple management and advanced features for any business environment.

With This Product You Can...

  • Add high performance storage for file sharing, backup and virtualization initiatives
  • Easily expand storage with DynamicRAID by mixing and matching different hard drive sizes and set up provision-free volumes
  • Share data across Windows, UNIX/Linux, and Macintosh Platforms
  • Replicate data between multiple locations for disaster recovery
  • Backup to disk, VTL, or tape



DynamicRAID® – A Brand New Spin on Managing Disks

Don’t limit yourself to the features of traditional RAID. With the combination of DynamicRAID and SnapServer your protection is automatically optimized for redundancy and capacity without manual intervention. Add or replace SnapServer hard drives at any time to expand existing storage pools and take advantage of drive size mismatches without wasting space.

High availability is further delivered with fully redundant, hot-swappable components such as power supplies, fan modules, battery backup modules, and SAS expansion ports.

  • Mix and match drives of different sizes to dynamically grow storage pools
  • Choose from single or dual parity protection with the click of your mouse
  • Automatically optimizes RAID levels as drives are added to the storage pool
Why You Need It...
  • DynamicRAID allows you to add storage your SnapServer DX by adding or replacing hard drives without downtime

Revolutionary Volume Management – Let GuardianOS® Do the
Heavy Lifting

Forget about provisioning. Create limitless volumes on your SnapServer DX Series and they will automatically share the available space in the disk storage pool; this means that volumes will only occupy as much space as their data requires, leaving space available to other volumes on demand. Storage volumes can also automatically grow and shrink as needed, and administrators can assign optional quotes to control volume sizes across the storage pool.

  • Create volumes without size limits
  • Dynamically grow and shrink volumes independently and on demand with no downtime
  • Grow volumes automatically by adding or replacing hard drives to increase the storage pool capacity
Why You Need It...
  • The SnapServer NAS volumes share a common storage pool and can grow or shrink on demand with no IT intervention

Unified Storage – Freedom of Choice

Consolidate your storage by hosting both block and file level data on your SnapServer NAS system. Utilize common networking protocols for file sharing, collaboration and backup, or host database storage and virtualized servers on SnapServer iSCSI LUNs simultaneously.

  • File level access with SMB, NFS, AFP, HTTP, FTP protocols or block level access with iSCSI
  • Store your block and file-based data on a single SnapServer
  • Support your server consolidation and virtualization initiatives
Why You Need It...
  • Unified Storage allows you to store block and file-based data on a single SnapServer

Advanced Security – Intelligence Matters

The SnapServer can provide local security for small infrastructures or join larger networks that include complex security policies. With full integration into Windows Active Directory domains, UNIX domains, and cross-compatibility for mixed security environments, the SnapServer allows you to maintain consistent permissions for users with multiple system types, with minimal intervention, across your business infrastructure.

  • Fully integrates with your existing Windows Active Directory Domain or UNIX NIS user and group database
  • Automatically stays synchronized with the full set of 30 distinct AD permission attributes
  • Windows-to-UNIX ID mapping and local permission management
Why You Need It...
  • Advanced security allows your SnapServer to fully integrate within any corporate security infrastructure

Expansion – to 384TB

Grow your SnapServer storage pools by adding drives to existing DynamicRAID sets, or expand by attaching the external, 2U, 12-bay SnapExpansion chassis. Pay as you grow without buying more storage than you need at any given time with SnapServer NAS. Scale a single SnapServer up to 384TB while maintaining simple, provisioning-free management.

Writable snapshot supports allows for a flexible test environment without putting your critical data at risk and without the need to do a complete volume copy of the data to test applications under development or for piloting purposes.

  • Expand existing DynamicRAID arrays within individual chassis
  • Attach SnapExpansion chassis to scale beyond the SnapServer head units
  • Create an additional storage pool within each expansion chassis and allocate as needed
Why You Need It...
  • Expand your SnapServer storage internally by adding or replacing hard drives, or externally by attaching the SnapExpansion chassis
