    6Gb/s MegaRAID SAS RAID Controllers User Guide Glossary August 2012 Glossary BIOS Acronym for Basic Input/Output System. Software that provides basic read/write capability. Usually kept as firmware (ROM-based). The system BIOS on the motherboard of a computer boots and controls the system. The BIOS on your host adapter acts as an extension of the system BIOS.
  • Page 89 A piece of hardware (such as a video monitor, drive, printer, or CD-ROM) used with a computer and under the control of the computer. SCSI peripherals are controlled through a MegaRAID SAS RAID controller (host adapter). The interface required to transmit and receive data packets transferred across the serial bus.
  • Page 90 6Gb/s MegaRAID SAS RAID Controllers User Guide Glossary August 2012 SATA Acronym for Serial Advanced Technology Attachment. A physical storage interface standard, SATA is a serial link that provides point-to-point connections between devices. The thinner serial cables allow for better airflow within the system and permit smaller chassis designs.
