RAID Migration
A feature in RAID subsystems that allows for changing a RAID level to
another level without powering down the system.
RAM
Random Access Memory, the "built-in" readable and writable data storage
that comes with (or can be added to) a computer.
RISC
Reduced Instruction Set Computing, architecture for an application-specific
processor.
RJ-11, RJ-45
Registered Jacks (sometimes described as RJ-XX), a series of telephone
connection interfaces (receptacle and plug) that are registered with the U.S.
Federal Communications Commission (FCC). The most common telephone
jack is the RJ-11 jack, which can have six conductors but is usually
implemented with four. The RJ-11 jack is likely to be the jack that your
household or office phones are plugged into from the ordinary "untwisted"
wire (sometimes called "gray satin" or "flat wire") that people are most
familiar with. The RJ-45 is a single-line jack for digital transmission over
ordinary phone wire, either untwisted or twisted; the interface has eight pins
or positions.
ROM
Read-Only Memory, built-in computer memory containing data that
normally can only be read, not written to. ROM contains the programming
that allows a computer to be "booted up" each time you turn it on. Unlike a
computer's random access memory (RAM), the data in ROM is not lost when
the computer power is turned off; a small long-life battery in your computer
sustains the ROM.
SAF-TE
SCSI Accessed Fault-Tolerant Enclosure, an “open” specification designed
to provide a comprehensive standardized method to monitor and report
status information on the condition of disk drives, power supplies, and
cooling systems used in high availability LAN servers and storage
subsystems. The specification is independent of hardware I/O cabling,
operating systems, server platforms, and RAID implementation because the
