RAID Recovery - Disk enclosure
A disk enclosure refers to a chassis designed to hold disk drives. Drive enclosures also provide power to the drives. They feature a mechanism to communicate to one or more separate computers. External hard disk drives, external DVD-ROM drives, and other devices are built around disk enclosure.
Disk enclosures convert the data [...]
RAID Recovery - Disk Array controller
A disk array controller (DAC) controls the physical disk drives. Each DAC detects whether the respective drive it is connected to is an ATA drive or SCSI drive and communicates with that drive using appropriate protocol. DAC preferably supports Serial ATA and Serial Attached SCSI interface specification.
ATA RAID controller
A simple [...]
RAID Recovery - Host adapter
Fiber Channel
There are two types of WWN: a node WWN (WWNN) and a port WWN (WWNP). A node WWN is shared by all ports on an HBA, where as a port WWN is unique to each port.
Some of the Fiber Channel HBA manufacturers include Brocade Communications Systems, Emulex, QLogic, LSI, and [...]
RAID Recovery - Host adapter
A host adapter, also known as host bus adapter (HBA) is one of the components that connect a host system to other network or storage devices. Host adapters mostly connect SCSI, Fiber Channel and eSATA devices.
SCSI host adapter
An SCSI host adapter is used to connect an SCSI bus to a computer. [...]
RAID Recovery - ESCON
Enterprise Systems Connection (ESCON) is a fiber optic channel created by IBM to connect mainframe computers to peripheral storage devices such as disks and tapes. Developed in 1990, ESCON was the successor of copper-based parallel Bus & Tag channel technology. Bus & Tag used a parallel environment, but ESCON uses serial bit-by-bit [...]
RAID Recovery - Fiber Connectivity (FICON)
Cable Support
FICOM has the ability to employ FC fiber optic cables- both short wavelength and long wavelength. Long wavelength cables are popular because of their superior optical power budget and bandwidth capabilities. FICON does not support copper FC cables.
Uses
FICON is used in IBM mainframes mainly due to its compatibility with [...]
RAID Recovery - Fiber Connectivity (FICON)
FICON (Fiber Connectivity) is a high-speed I/O interface developed by IBM to connect mainframes to storage devices such as disk storage and tape drives. Mainframes are computers based on IBM z/Architecture. FICON uses a mapping technology developed for Fiber Channel (FC) protocol. It has a fabric topology that utilizes FC [...]
RAID Recovery - InfiniBand
InfiniBand is a type of communication link used in high-performance computing (HPC). The InfiniBand architecture is based on the Virtual Interface Architecture, and it allows data flow between processors and high performing I/O devices such as storage disks. InfiniBand is highly scalable. It delivers high quality of service and failover. Because of [...]
RAID Recovery - Journaling file system
A journaling file system is file system that before submitting the changes to the main file system logs them to a journal with the objective of protecting the file systems against any probable form of corruption in the event of power failure or system crash. These logs are usually circular [...]
RAID Recovery - RAIN
Redundant/Reliable Array of Inexpensive/Independent Nodes or RAIN is a type of computer storage. RAIN is advancement over Raid and the former is an open architecture approach to computer storage. In open architecture, commodity or low cost computing hardware and high end and intelligent management software are brought together or combined so that [...]
