a. This applies to the drives; the limits for the library are given in the library user guide.
b. This is a per-drive value. Total sustained transfer rate for the library depends on the number of drives installed in the library.
c. The sustained transfer rate can increase by an average of 2.6 times with compression, dependent on the type of data.
d. The actual burst transfer rate is limited by the performance of the SCSI HBA, the controller, and the buffer control hardware.
