xii Scalar AIT 440/480
The library's robotic cartridge handling mechanism (CHM) responds to
commands from the host application to move AIT data cartridges
between tape drives and storage slots, while the tape drives read and
write data. You can insert and remove cartridges through the entry/exit
port without opening the library door.
About the Scalar AIT 440 and Scalar AIT 480
The following illustrations and descriptions summarize the important
library features. For library specifications, refer to .
The Scalar AIT 440 contains 40 data cartridge slots, while the Scalar
AIT 480 contains 80 data cartridge slots. Both libraries can include up
to four 3.5” form factor Sony

AIT

tape drives. The libraries can
operate as five SCSI devices on up to five SCSI buses. When the library
is equipped with AIT-1 drives, the library is a differential SCSI-2 device
and the drives are differential Fast/Wide SCSI-2 devices. The library can
be a differential SCSI-2 device and the drives are differential SCSI-2
Fast/Wide devices. When equipped with AIT-2 drives, the library can
be configured as a high voltage differential (HVD) Wide Ultra SCSI
device, or as a low voltage differential (LVD) Wide Ultra SCSI device.
When operating with four AIT-2 tape drives and assuming an average
data compression ratio of 2:1, the Scalar AIT 440 can store up to 4.0
terabytes of information on 40 Advanced-Metal Evaporative (AME
™
)
data cartridges (SDX2-50C), while the Scalar AIT 480 can store up to
8.0 terabytes of information on 80 AME cartridges.
