GLOSSARY

Adaptive Lossless Data Compression (ALDC) An advanced data compression

algorithm that provides an average compression ratio of 2:1 across multiple data types. See also Compression.

Advanced Metal Evaporated (AME) media A state-of-the-art tape technology designed for data storage. VXAtape cartridges use AME media.

American National Standards Institute (ANSI) Organization that sets standards for SCSI and the safety of electrical devices.

B

Bit error rate (BER) The probability that a transmitted bit will be received in error. The BER is expressed as a ratio of error bits to total number of bits.

Buffer A temporary storage area, usually in Random Access Memory (RAM). The tape drive’s read and write buffers act as holding areas that enable the tape drive to balance the rate at which it transfers data to or from tape with the data transfer rate of the host. The VXA-320 tape drive has a 16-MB buffer.

Bus In a network, the electrical pathway between a computer and other devices.

C

CAW-After-Write (CAW) A process that improves data integrity by reading data immediately after it is written and writing the packet again if an error is found. Individual packets are rewritten as necessary, optimizing speed and capacity.

Compression The reduction in size of data to save space. Either the backup application or the tape drive can perform compression. See also Adaptive Lossless Data Compression (ALDC).

Cyclic redundancy check (CRC) The error detection technique that checks for uncorrected data during a read operation.
