The XenData SX-250 archive server manages a robotic LTO tape library and creates a cost effective digital video archive that is ideal for professional video applications.

The SX-250 runs XenData6 Server software on a Windows Server 2012 R2 platform and scales to 540 TB of near-line LTO. It is available in 16 standard configurations – supporting up to a 90 slot LTO tape library with up to two internal LTO-7 drives.

The SX-250 typically connects to a network as illustrated below. Files can be archived and restored in two ways: as a standard file system where files and folders are written and read just like writing to and reading from disk; or alternatively as Object Storage using a XenData XML API.

Key Benefits

Native Compatibility with Most Applications

The digital archive has a file/folder interface for both archiving and restoring. Furthermore, there is no need to load any special software on client computers. This means it works with most applications – from MAMs to Windows Explorer or Finder.

Alternatively the SX-550 Series has an Object Storage interface, accessed via an API. A growing number of MAMs are using this Object Storage interface.

Supports Multiple Simultaneous Applications

Create multiple LTO cartridge groups and use for different applications. For example combine a MAM archive and a simple file-folder archive – all with one XenData system.

Designed for Networks

A built-in 6 TB to 18 TB disk cache delivers high performance in a network and the NAS architecture makes it easy to deploy. Provides two 1 GigE ports. Options add either two 10 GbE ports or two fibre channel ports for SAN connectivity.

The solution is optimized for both CIFS/SMB and FTP network protocols. You can use either protocol – or both simultaneously.

Supports Windows, Mac and FTP Clients

Windows, Apple OS X and FTP clients are natively supported.

Fast Archiving

Files are written at disk speed. The system does not wait for LTO cartridges to be mounted and moved to the end of data.

Fast Restores

The system restores a queue of files in the shortest possible time. The restore requests are processed in an order that minimizes unnecessary tape movement.

Partial Restores with LTO

Allows a clip to be restored from LTO without the need to restore the whole file.

Built-In LTO Data Protection

The system will automatically create extra backup copies of LTO cartridges for offsite retention.

LTFS Prevents Vendor Lock-In

LTO cartridges are written in either the LTFS interchange format or the open standard TAR format. The use of a standard format prevents vendor lock-in – proprietary formats mean that it is very costly to ever convert to another vendor.

Industry Standard File Security

The archive server integrates fully with the Microsoft Windows security model based on Active Directory. There is no need to configure proprietary user access.

Manages Unlimited Externalized Cartridges

The system manages any number of externalized cartridges, providing an unlimited total capacity. There are no license fees for externalized capacity.

When offline files are accessed, the system prompts with email alerts and on-screen notifications, identifying the cartridge that should be imported back into the system.

A range of different reports helps manage the entire archive including all externalized cartridges.

Strong File Version Control

Accidentally over-wrote or deleted a file? No problem; just select the file and restore deleted files or previous versions.

Scales to 540 TB of Near-line LTO Capacity

Supports a wide range of robotic libraries with up to 90 slots, including models from from Dell, HP, IBM, Oracle, Overland, Quantum and Qualstar.
