XenData Software

Functionality


Interface:


All managed tapes and the disk cache are virtualized as one standard Windows logical drive letter.

The Windows offline attribute identifies when a file is no longer on disk cache. This prevents network timeouts.


Interface:


The XenData software creates a single logical drive locallywhich may be shared as one or more network shares.

Advantage: the archive may have multiple uses without need for special interface software, for example:

► Archive for MAM ► P2 Raw Footage Archive ► Archive for FCP users


File group Rules for OS X Clients

Automatically implements file group rules forManagement of Resource Fork files and .DS_Store files.

Mac clients are automatically supported.


Strong Adherence to Standards:

Standard Tape Format

XenData software writes to the data tapes in industry standard TAR format. This means that files may be read with third party utilities.


Strong Adherence to Standards:

Standard Security

XenData software adheres to the standard Microsoft security model based on Active Directory.


Hierarchical Storage Management:

XenData Supports Three HSM Tiers

Online refers to files in disk cache. Policies determine how long files are retained online.

Nearline refers to files on a tape within a library or in a stand-alone drive.

Offline refers to files held on tapes on the shelf.


Hierarchical Storage Management:


HSM and Offline Files:

Offline Files

When a file is no longer on disk or on a tape within a library or stand-alone drive, it is offline. However, XenData software maintains offline files in the file system. If there is an attempted access of an offline file, the XenData Alert Module will identify which tape should be inserted into a drive or library to bring it back to nearline status. Notification is via on-screen messages or email alerts.


Data Protection:

Tape Cartridge Replication

Tape cartridge duplicates are generated automatically, creating a copy for offsite retention.


Data Protection:

Rapid Restore of File System

XenData’s metadata backup program provides a rapid restore of the system in case of total disaster or RAID failure.


Additional Software Features:

Supports Multiple Tape Sets

The Administrator may allocate groups of files or folders to specific groups of tapes.

Consequently, related files can be grouped together on the same set of tapes.



Partial Restore based on Byte Offset

File fragmentation allows rapid restore of a portion of a file.



Configurable Disk Retention

The Administrator may configure the disk retention policy by folder and/or file type.


Data Transfer:

Easy export from one system and import to another

Each full tape contains a tape catalog that provides rapid import of file contents to another file system. A tape may be finalized at any time, creating the tape catalog and preventing additional writing to the tape.


Tape Cartridge Repack:

Allows Recovery of Space from Deleted Files

The administrator is able to repack a tape which causes all current files (i.e. excluding files that are deleted or are old versions) to be re-written. The original tape is then shown as quarantined, ready for reformat.

First check Tape VolumeStatistics to determinespace that Repack wouldrecover.





Then initiate a repack operation.





After the repack operationhas completed, the original tapes may be reformatted.


Explorer Extensions – Smart Copy & Paste

Allows Optimized Restore

Files are restored in tape order.


Explorer Extensions – Pre-fetch

Files are transferred to disk cache

Files are pre-fetched to disk and restored in tape order.


Explorer Extensions – Flush

Allows rapid flushing of files from disk
