Question | Answer |
dd command | A Linux command that can be used to write image files to a device such as a USB flash memory drive or hard disk. |
disk imaging software | Software used to copy sectors between devices. For example, you can use disk imaging software to copy an ISO image to a disk device sector-by-sector, preserving the image’s boot sector. An ISO image copied in this way can be used to start the system BIOS. |
disk mirroring | A RAID configuration consisting of two identical hard disks to which identical data is written in parallel, thus ensuring fault tolerance. Also known as RAID 1. |
disk striping | A RAID configuration in which a single file is divided into sections, which are then written to different hard disks concurrently to speed up access time; this type of RAID is not fault tolerant. Also known as RAID 0. |
disk striping with parity | A RAID configuration that incorporates disk striping for faster file access, as well as parity information to ensure fault tolerance. Also known as RAID 5. |
fault tolerant | Term used to describe a device that exhibits a minimum of downtime in the event of a failure. |
File Transfer Protocol (FTP) | The most common protocol used to transfer files across the Internet. |
firmware RAID | A RAID system controlled by the computer’s BIOS. |
hardware RAID | A RAID system controlled by hardware located on a disk controller card within the computer. |
Hypertext Transfer Protocol (HTTP) | The protocol used to transfer information over the Internet. |
installation log files | The files created at installation to record actions that occurred or failed during the installation process. |
Internet SCSI (iSCSI) | A SCSI technology that transfers data via TCP/IP networks. |
iSCSI initiator | The software and hardware components that can be used to transfer files to and from an iSCSI target. |
iSCSI target | An external iSCSI storage device that hosts one or more hard disks. |
ISO image | A file that contains an ISO filesystem. |
Kickstart Configurator | A graphical utility that can be used to create a kickstart file. |
kickstart file | A file that can be specified at the beginning of a Fedora Linux installation to automate the installation process. |
Logical Unit Number (LUN) | A unique identifier for each device attached to any given node in a SCSI chain. |
Network File System (NFS) | A distributed filesystem developed by Sun Microsystems that allows computers of differing types to access files shared on the network. |
overclocked | Term used to describe a CPU that runs faster than the clock speed for which it has been rated. |
Parallel SCSI | The traditional SCSI technology that transfers data across parallel cables. |
Redundant Array of Independent Disks (RAID) | The process of combining the storage space of several hard disk drives into one larger, logical storage unit. |
SCSI ID | A number that uniquely identifies and prioritizes devices attached to a SCSI controller. |
segmentation fault | An error that software encounters when it cannot locate the information needed to complete its task. |
Serial Attached SCSI (SAS) | A SCSI technology that transfers information in serial mode rather than the traditional parallel mode. |
software RAID | A RAID system that is controlled by software running within the operating system. |
spanning | A type of RAID level 0 that allows two or more devices to be represented as a single large volume. |
Storage Area Network (SAN) | A group of computers that access the same storage device across a fast network. |
terminator | A device used to terminate an electrical conduction medium to absorb the transmitted signal and prevent signal bounce. |
