A XenData SX-500 Series Archive Server manages one or more LTO tape libraries and RAID. It provides a highly scalable network attached storage device where files are written to LTO tapes and disk. SX-500 Archive Servers run a Windows Server 2008 R2 operating system and combine two leading products: HP DL380 G8 server hardware and XenData6 Server software. The SX-500 Series is offered in three standard configurations, each optimized for video archive applications.
Standard File System Interface
The digital archive accepts all file types and presents them in a single Windows file system. Files are written to and retrieved from the archive as though from a standard magnetic disk drive.
Windows and Mac Compatibility
Windows and Apple OS X clients are natively supported without need for loading any client software.
Standard Network Protocols
The solution is optimized for CIFS/SMB and FTP file transfers.
Manages Nearline Disk, Nearline and Offline Tape
The administrator defines policies for RAID caching that can be tailored for different file types and folders.
Standard POSIX tar tape format
The archived files are written to LTO tape using the standard POSIX tar format. This means that, in addition to using XenData software, files may be restored using a wide range of Linux and UNIX operating systems.
The system restores a queue of files in the shorted possible time. The restore requests are processed in an order that minimizes unnecessary tape movement.
File Version Control
The archive server provides comprehensive file version control. Deleted files and old file versions may be restored from tape (unless the files have been purged using a repack operation).
The system automatically generates replica data tape cartridges that may be exported from the library for off-site retention. Furthermore the tapes may be rapidly imported into a replica DR system.
Industry Standard File Security
The archive server integrates fully with the Microsoft Windows security model based on Active Directory.
Partial Read of Large Files
With very large files there is often a need to read only a portion of the file. For example, this frequently occurs with multi-gigabyte video files when a short clip is requested. The SX Archive Servers support partial reading of large files.
Repack of Tapes
This copies only current files, excluding deleted files and old versions of files, to new tapes. Benefits: permits recovery of capacity from rewritable tapes; also provides ability to easily migrate to future generations of LTO.
Transfer of Content between Systems
Export and import functions allow content to be easily transferred from one location to another.
Supports WORM Tape
The system supports both standard rewritable data tape and unalterable WORM. The use of unalterable WORM tape cartridges is especially important for legal compliance applications.
Tape Contents and Search Reports
The files contained on any tape, including offline tapes, can be listed in a report which may be exported to Excel.
Metadata Backup and Restore
A file system metadata backup and restore utility provides rapid system restore in case of rebuild after RAID failure.
A software module is included which provides e-mail and on-screen alerts. These are tailored to the needs of archive system operators, system administrators and IT support personnel.
