DNS
The Domain Name System is a hierarchical naming system built on a distributed database for
computers, services, or any resource connected to the Internet or a private network. Most impor-
tantly, it translates domain names meaningful to humans into the numerical identifiers associated
with networking equipment for the purpose of locating and addressing these devices worldwide.
Disk
Refers either to a HDD unit or the direct block addressing scheme used to store and retrieve digital
data on the HDD. When the RDX 8000 unit is in disk mode direct block addressing is used to access
the contained RDX media.
ESD
Electro Static Discharge is the sudden and momentary electric current that flows between two
objects at different electrical potentials The term is usually used in the electronics and other indus-
tries to describe momentary unwanted currents that may cause damage to electronic equipment.
HDD
Hard Disk Drive refers to the core storage device using rotating magnetic media to store digital
information. RDX cartridges make use of embedded HDD’s to store data.
iSCSI
Internet Small Computer System Interface, an Internet Protocol (IP)-based storage networking
standard for linking data storage facilities. By carrying SCSI commands over IP networks.
iSNS
Internet Storage Name Service, protocol that allows automated discovery, management and con-
figuration of iSCSI devices on a TCP/IP network.
LED
Light Emitting Diode is a semiconductor light source. The RDX 8000 uses LED’s to provide power
switch, eject button, and cartridge status indication. LED technology is also used to provide the
backlighting for the LCD display used in the OCP.
MTU
In computer networking, the Maximum Transmission Unit of a communications protocol of a layer is
the size (in bytes) of the largest protocol data unit that the layer can pass onwards. MTU parameters
usually appear in association with a communications interface (NIC, serial port, etc.).
OCP
Operator Control Panel includes display, buttons and LED’s and enables the user to operate the unit
from the front
RDX
Is a removable disk technology originally developed by ProStor.
