Channel Calibration
System performance is further optimized by a feature called channel
calibration, in which the drive automatically customizes each read/write
data channel to compensate for variations in such things as the
recording channel's transfer function, the media, and characteristics of
the drive head.
Data Cartridge Capacity Scaling
The SET CAPACITY SCSI command enables a customer to capacity scale a
data cartridge to enable faster random access. As an example, a
customer could capacity scale a data cartridge to 20% of its normal
length which improves the average access time by almost a factor of 5;
however, it also reduces the native capacity of the tape to 500 GB.
Inhibit Firmware Down-leveling
The drive provides the capability to prevent loading and installing drive
microcode via a firmware update (FUP) tape if the firmware level
contained in the FUP tape is older than the code level already installed.
This option is controlled by the host application. No checking will be
performed if the firmware level is loaded via the host interface.
SAS Interface
The drive has a dual port 6 Gbps SAS (Serial Attached SCSI) host
interface.
