GLOSSARY

R

RAID Controller A Redundant Array of Independent Disks Controller is a collection of disk drives that employs two or more drives in combination for fault tolerance and performance.

Read-After-Write (RAW) 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.

RoHS The RoHS Directive mandates that electrical and electronic products put in the market within the European Union (EU) shall contain restrictive levels of the following substances:

Lead (Pb) Cadmium (Cd) Mercury (Hg)

Hexavalent Chromium (Cr6+)

Polybrominated Biphenyls (PBB) Polybrominated Diphenyl Ethers (PBDE)

S

SCSI Small Computer System Interface. A device interface that has been certified as an American National Standard by ANSI. The standard contains the electrical specifications, communication protocol, and command structure necessary to connect various computer peripherals to a host computer.

SCSI ID A unique address assigned to each device attached to a SCSI bus. See also Bus.

Segment The format structures contained within the data buffer. Each segment contains 1,220 packets of data, ECC, and CRC information.

Setmark A mark written by the tape drive to allow fast searching to a point on the tape without having to know the number of records or filemarks that precede the point. A setmark is a special recorded element within a partition, that contains no user data, and provides a segmentation scheme hierarchically superior to filemarks for use in addressing or fast positioning on high-capacity storage devices (also called Save-Set Mark).

Streaming An operational mode that occurs when the data transfer rate to or from the host closely matches the tape drive’s data transfer rate, allowing the tape drive to read or write data in a continuous stream.

T

Termination In SCSI, termination refers to placing a resistor (terminator) at both physical ends of the SCSI bus to prevent signal reflection.

Transfer rate The transmission speed of a communications line. The tape drive transfer rates are measured in megabytes per second (MB/sec).
