It is a major new release which incorporates a large number of product improvements. A summary of changes follows:

Increased Operating System and Hardware Support. Support for the Windows Server 2003 family of operating system added. Support for additional tape libraries added.

Improved Performance. Performance is improved significantly. This was undertaken especially to take advantage of the high data transfer rates associated with SAIT.

Improved Compatibility. Improvements in integration with third party application software and with anti-virus software, open file managers and backup packages are included in Version 3.20.

Improved Device Handling. Support is added for devices within the library attached via multiple SCSI and fibre channel buses. 

Improved Usability. A large number of small improvements are included.

Bug Fixes and Reliability Improvements. A number of small bug fixes and reliability improvements are implemented.

A summary of changes follows:

Improved Hardware Support  Added mail-slot support for Breece Hill 10 PAK tape libraries (Breece Hill firmware version 1.47).

Bug Fixes and Reliability Improvements  Improved reliability of AIT-WORM initialization. Fixed bug that caused lock-up on file read with some multi-processor machines. Fixed bug that could cause spurious error messages with File Groups that were not saved to tape and which had ‘save history’ disabled.

A summary of changes follows:

Enhancements  File Group rules are now case insensitive by default. Improved support for email alerts on NAS servers. Improved support for DSM tape libraries

Bug fixes, including: Fixed potential Windows STOP error that can occur with versions 3.22 and 3.23 under extreme stress conditions. Fixed incorrect file sizes and attributes when upgrading from prior version. Fixed incorrect file size following Import Catalog or Import Data of large files > 4GB. Fixed bug that could cause spurious error messages with File Groups that were not saved to tape and which had ‘save history’ disabled.

It is a major new release which incorporates a large number of product improvements. A summary of changes follows:

Available in Two Editions  In addition to the Advanced Edition, the software is alternatively available in the Video Edition. The Video Edition is designed for digital video archiving applications and must be run on a higher performance server. The Video Edition optimizes data throughput at the expense of increased cache memory consumption. Consequently, the minimum RAM and other server hardware requirements are higher than for the Advanced Edition.

Increased Range of Supported Tape Drive and Library Types  This release now supports a broader range of libraries including those with LTO-2, LTO-3 and SDLT 600 drive types. Comprehensive support for HP’s LTO-3 WORM and Quantum’s DLTIce tape formats is included.

Increased Hardware Diagnostics and Support The following are added: (a) handling of tape alerts from drives; (b) pages of information about tape drives and libraries; (c) the ability to disable individual tape drives and the library; (d) the ability to open a library mail slot via the user interface; (e) automatic idle demount of tapes from drives; and (e) improved recovery from replication failures caused by drive hardware problems.

Increased Media Information  A "last alert" field is added to the information maintained about each tape cartridge.

Drive Cleaning  Support for handling of cleaning cartridges and automatic drive cleaning are added.

Quarantined Media  A quarantined media set is added for cartridges that cannot be identified or whose labels conflict with the database.

Change to POSIX TAR Tape Format  The data format written to new XenData Volumes is changed from GNU TAR to POSIX TAR which allows file fragments to be increased in size beyond the 8 GB limit of the GNU standard. This version 3.30 is fully backwards read compatible with previous versions of the software.

Improved Performance with Large Files  A number of performance improvements are included in this release, especially for large files. In particular, when a file is being read from tape, data is sent to the application as soon as it has been read rather than waiting for the complete fragment file to be read before returning any data.

Bug Fixes  A number of bug fixes are added including the following: (a) improved operation of the XenData Management Console UI; (b) support for path names longer than 256 characters; (c) improved handling of errors caused by hardware failures is added; (d) a bug is fixed that meant ‘import catalog’ operations would not always show the correct write time for a file.
