Redundant Power Supply (Feature Code 1900); Feature Licenses - IBM System Storage TS3310 Setup And Operator Manual

Speed Matching
To improve system performance, the Ultrium 3 Tape Drive uses a technique called
speed matching to dynamically adjust its native (uncompressed) data rate to the
slower data rate of the attached server.
Channel Calibration
The channel calibration feature of the Ultrium 3 Tape Drive customizes each
read/write data channel for optimum performance. The customization enables
compensation for variations in the recording channel transfer function, media
characteristics, and read/write head characteristics.
Power Management
The Ultrium 3 Tape Drive's power management function controls the drive's
electronics so that part of the electronics completely turn OFF when circuit
functions are not needed for the drive's operation.

Redundant Power Supply (Feature Code 1900)

The optional redundant configuration power supplies may be hot swapped
without interrupting library operation. Each supply in a control module and
expansion module includes its own input AC line cord. During redundant
operation, each supply carries one-half the power load. If a line cord or power
supply fails, the second supply sources the complete power load. Optionally, a
single power supply and line cord may be installed if redundant power is not
required. The second power supply slot is physically covered in this configuration.
The library may be upgraded to redundant power at a later time.

Feature Licenses

A feature license controls the setting of feature-enabled flags that are based on a
user input key and the library serial number that is stored in the library vital
product data (VPD). A unique key exists for each library based on an encryption of
the chassis serial number and a feature code.
After a feature is enabled, it cannot be disabled. The library's serial number can
only be assigned at the factory.
The library uses feature licenses to enable the Capacity Expansion feature and the
Path Failover feature.
Capacity Expansion (Feature Code 1640)
At any time, the Capacity Expansion feature (Feature Code 1640) allows you to
enable the unused storage slots within a library via a firmware license key.
To see your library's current configuration:
v From the Operator Panel: view the Capacity View home screen.
v From the Web User Interface: Monitor System → System Summary
