Physical Disk Drive
A single hard disk drive. Each physical disk drive is assigned a unique
identification address.
Platform
An underlying computer system on which application programs can run. A
platform consists of an operating system, the computer system's
coordinating program, and a microprocessor, the microchip in the computer
that performs logic operations and manages data movement in the computer.
Plug and Play
The ability to install peripheral cards or other devices without requiring
manual configuration by the user.
RAID
Redundant Array of Independent Disks, a collection of two or more disks
working together in an array. Mylex RAID controllers implement this
technology to connect up to 15 SCSI devices per channel. The different
forms of RAID implementation are known as “RAID levels.” See also
Berkeley RAID Levels, Disk Array, and RAID Levels.
The system manager or integrator selects the appropriate RAID level for a
system. This decision will be based on which of the following are to be
emphasized:
• Disk Capacity
• Data Availability (redundancy or fault tolerance)
• Disk Performance

RAID Advisory Board (RAB)
An association of companies whose primary intention is to standardize
RAID storage systems. Mylex is a member of RAB.
