Data Rate Matching
A physical library has limitations. A customer may have mixed backup software environments where
sharing the library becomes difficult. To manage this currently, the operator will create partitions (virtual
libraries) and have each application assigned to one or more partitions. These partitions are fixed, and
Applications mapped into one partition can't claim media and storage space from partitions not assigned
to them.
This method can be inflexible and require a good deal of management overhead to reconfigure and
support.
However, with the ESL G3 Automated Media Pool (AMP) a "ghost" partition acts as a flexible media pool
where media can be assigned to or removed from partitions as needs change - all without forcing
application reconfigurations.
An extended import/export station creates a logical bulk load/unload capability inside the library for faster
imports and exports. A 72-media slot mailbox provides one of the largest bulk load/unload in the industry
offering the ability to load or unload media without having to take the library offline or stop currently-
running backup jobs (as would be required when opening the whole front door).
The library I/E Station configuration can accommodate:
1 to 8 24-slot Import/Export (I/E) stations in the control module and first 7 expansion modules.
OR
1 24-slot I/E in the control module and up to 7 72-slot I/E stations in first 7 expansion modules.
HP LTO (Linear Tape Open) Ultrium Tape Drives use best of breed technology. By taking the best features
from other tape technologies and combining them into a single new technology, Ultrium tape drives are in
a league of their own. Inclusion of innovative features such as Adaptive Tape Speed (ATS) ensure that
Ultrium drives can meet the performance and reliability demands of a library environment. LTO technology
is an open industry standard format; thus data written on HP Ultrium Tape Drives can be interchanged
directly with Ultrium Tape Drives from other vendors.
Data Rate Matching combines sophisticated buffer management with HP's exclusive variable Adaptive
Tape Speed (ATS) technology, to allow the tape drive to match its transfer rate to the host speed
dynamically and continuously across the wide range of transfer rates. This feature ensures that the tape
drive continues to stream data regardless of the environment, and brings two big advantages:
It optimizes backup performance and maximizes overall efficiency allowing the drive to respond
immediately to any speed changes from the host
It minimizes rewinding and repositioning of the tape, significantly reducing physical wear and
increasing reliability
It minimizes the power requirements for the drive by reducing the number of repositions needed
