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.
