Glossary

Elements

SCSI designation for any device or bin in the library that can hold a cartridge. SCSI elements include storage bins, tape drives, load port bins, and the picker.

EMI

Electro-Magnetic Interference refers to unwanted electrical noise present on a power line. This noise may leak from the power lines and affect equipment that isn't even connected to the power line. Such leakage is called a magnetic field. Magnetic fields are formed when unwanted noise voltages give rise to noise currents. Such noise signals may adversely affect electronic equipment and cause intermittent data problems.

ESD

Electrostatic Discharge

Host

The device or devices to which the library is connected.

IEC

The International Electrotechnical Commission is based in Geneva, Switzerland.

Load port

The revolving assembly on a front door of enterprise libraries that incorporates a revolving drum and tape cartridge bins for loading and unloading tape cartridges.

LTO-2

Linear Tape-Open is a tape drive specification backed by HP, IBM and Seagate. Ultrium 460 tape drives (LTO-2) are HP’s second generation of LTO tape drives.

LVD

Low Voltage Differential or LVD is a type of electrical signaling for parallel SCSI and can reach distances up to 12 meters. All HP Ultrium 460 tape drives are LVD devices. SDLT tape drives can be LVD or HVD devices.

MSBF

Mean Swaps Before Failure

MTBF

Mean Time Between Failures

MTTR

Mean Time To Repair

NEMA

National Electrical Manufacturers Association

Network interface Card (NIC)

A NIC is a device that handles communication between a device and other devices on a network.
