About the SnapServer XSR Series

SnapServer XSR is the first data storage system that integrates the revolutionary Dynamic- RAID, a standards-based technology that gives you the ability to automatically expand storage pools and storage volumes independently, optimize your data protection levels and increase capacity with zero downtime. DynamicRAID provides the flexibility you need to manage your storage infrastructure without manual intervention, so that your business can grow without interruption. SnapServer XSR is the simplest unified NAS and iSCSI SAN storage for modern business applications — from virtualized server and Microsoft Exchange environments to backup and storage consolidation. Built on the proven GuardianOS platform with integrated features like snapshots and replication, SnapServer XSR lets any business run its storage like an enterprise, at one-tenth the cost. It's storage as it should be.

DynamicRAID – Automatic Capacity Growth with Thin Provisioning

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.

  • 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
BitTorrent Sync

BitTorrent Sync™ – Secure, Unlimited File-Syncing. No 3rd Party Cloud Required

It’s time to get rid of your expensive cloud storage provider. BitTorrent Sync™ is preinstalled on the SnapServer XSR 40 series NAS. Automatically sync files between directories on geographically distributed SnapServer systems. Access those files with any BitTorrent Sync™ client, server or mobile application. There are no limits on file sizes or file transfers so you can build your own high performance private cloud that is accessible from anywhere.

  • Full encryption with secret keys
  • Incremental peer-to-peer file transfers
  • Syncing performance increases as more devices are added
  • iOS, Windows Phone, Kindle, and Android Device Support
Why You Need It...
  • Synchronize and access your files from anywhere, from any device by simply exchanging secret keys or scanning QR codes.
RDX Integration

RDX Integration – Rugged, reliable disk-to-disk backup

SnapServer administrators can take advantage of Overland Storage RDX direct to disc backup. Plug an RDX QuikStor device into the SnapServer USB ports and selectively copy data from disk-to-RDX. Utilize RDX media as a form of backup and offsite disaster recovery. Copy data and remove for remote archiving, or as an easy way to move data between devices.

  • Format RDX media directly with XFS or NTFS
  • Fast reads and writes over USB3
  • Up to 2TB per RDX cartridge
Why You Need It...
  • Quickly backup individual files and directories to removable RDX media for archiving, backup and disaster recovery
Revolutionary Volume Management

Dynamic Volume Management – Let GuardianOS Do the Heavy Lifting

Forget about provisioning. Create limitless volumes on your SnapServer 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

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

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
High Performance Snapshots

High Performance Snapshots – Fast File Recovery

Protect SnapServer data by taking point-in-time virtual copies of the filesystem. Snapshots in GuardianOS are filesystem aware and are optimized to minimize write performance penalties. Recover files as needed by browsing mountable snapshot volumes. When properly implemented, snapshots enable faster operational recovery with little IT intervention. Snapshots also allow for flexible test environments 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.

  • Create snapshots volumes to track changes on thinly provisioned SnapServer data volumes
  • Mount snapshot volumes for drag-and-drop recovery of files
  • Unique snapshot implementation decreases write performance penalty
Why You Need It...
  • Protect from accidental file deletion and automatically track previous file states for fast file reversion
Expansion – to 288TB and Beyond

Expansion – to 288TB and Beyond

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 240TB while maintaining simple, provisioning-free management.

  • 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
Replication with SnapEDR

Replication with SnapEDR – Across the Hall or Across the Globe

Prepare for disaster recovery with Snap Enterprise Data Replicator (Snap EDR). With Snap EDR you can automatically replicate files between SnapServers, Windows, Linux, UNIX and Macintosh servers. Built for globally distributed businesses, Snap EDR will ensure that your files are moved off-site safely and securely.

  • Supports byte-level incremental replication, bandwidth throttling, compression and encryption
  • Share data with the distribute feature to remotely send documents
  • Remotely backup servers across the globe from a single management interface
Why You Need It...
  • Securely and efficiently replicate files off-site with Snap Enterprise Data Replicator to protect from disaster
