TM-L Series configurations - Mirroring Tape Libraries & Autoloaders
Solutions include: real time tape mirroring, real time data replication, tape mirrroring for UNIX, Windows, Linux, Netware, Mac; Formats include: LTO mirroring, DLT mirroring, SDLT mirroring, AIT mirroring... Multiple Tape Autoloader mirroring, Single Tape library mirroring, Multiple Tape library mirroring.
Unylogix's virtual tape library storage backup solutions complement existing tape technologies, tape autoloaders, and tape libraries. These tape library mirroring solutions are plug and play compatible and provide 100% transparent operation with all platforms, OS and backup management software.
Unylogix's virtual tape library storage solutions are based on fourth generation Tape RAID (Redundant Array of Independent Drives) ASIC technology, also known as RAIT (Redundant Array of Independent Tapes), to provide the highest tape performance, backup/restore automation, and fault tolerant data protection.
These series can be configured with one (TM-L models) or more (TM-LM models) tape libraries or autoloaders, to provide up to 4 times the performance of a single drive with unlimited flexibility; these models are specifically designed to address today’s backup concerns and increase data reliability and productivity with seamless scalability.
Please see the sections below for more details.
 |
The single tape library mirroring system transparently automate mirrored tape sets within a single tape library. Backup and restore operations perform up to 4 times the speed of a single tape drive providing reliable tape library operation. |
 |
The multiple tape library or autoloader mirroring system transparently automate mirrored tape sets across multiple tape libraries, thus providing data mirroring across 2, 3, 4 or 5 tape libraries or autoloaders with seamless scalability. |
Benefits
 Transparently Automate Mirrored Tape Sets
100% Transparent Operation with all backup
management software
Performs up to five copies of the same backup in the time of a single backup
Provides Fault Tolerant Tape Operation by
Simultaneously Creating a Parity Tape
Each Mirrored Tape Drive Set Connects to the Host via a TM-L Series Controller
Mirroring Solutions Provide Unlimited Flexibility and Scalability
Specifications
Supported RAIT Levels
Level 0 Striping two drives (2+0) or four drives (4 + 0)
Level 3 Striping two drives or four drives plus a parity drive (2+1 or 4 +1)
Level 1 Mirroring two, three, four, or five drives
Host and Array Interface
The host interface provides connection between the array controller and SCSI host system.
The array interface provides connection between the array controller and SCSI tape drives.
