A flawed RAID 5/6 also exists, but can result in data loss.) [10] For RAID 1, the devices must have complementary sizes. For example, a filesystem spanning two 500 GB devices and one 1 TB device could provide RAID1 for all data, while a filesystem spanning a 1 TB device and a single 500 GB device could only provide RAID1 for 500 GB of data.
RAID 6 – Like RAID 5, but with two parity segments per stripe. RAID 10 – Take a number of RAID 1 mirrorsets and stripe across them RAID 0 style. RAID 10 is distinct from RAID 0+1, which consists of a top-level RAID 1 mirror composed of high-performance RAID 0 stripes directly across the physical hard disks.
RAID (/ r eɪ d /; redundant array of inexpensive disks or redundant array of independent disks) [1] [2] is a data storage virtualization technology that combines multiple physical data storage components into one or more logical units for the purposes of data redundancy, performance improvement, or both.
Diagram of a RAID 1 setup. RAID 1 consists of an exact copy (or mirror) of a set of data on two or more disks; a classic RAID 1 mirrored pair contains two disks.This configuration offers no parity, striping, or spanning of disk space across multiple disks, since the data is mirrored on all disks belonging to the array, and the array can only be as big as the smallest member disk.
In software engineering, a WAR file (Web Application Resource [1] or Web application ARchive [2]) is a file used to distribute a collection of JAR-files, JavaServer Pages, Java Servlets, Java classes, XML files, tag libraries, static web pages (HTML and related files) and other resources that together constitute a web application.
This command is often used to obtain the IP of an abusive user to more effectively perform a ban. It is unclear what, if any, privileges are required to execute this command on a server. This command is not formally defined by an RFC, but is in use by some IRC daemons. Support is indicated in a RPL_ISUPPORT reply (numeric 005) with the USERIP ...
In video games, a raid is a type of mission in Massively multiplayer online role-playing games (MMORPGs) where a much larger number than usual of people specifically gather in an attempt to defeat either: (a) another number of people at player-vs-player (PVP), (b) a series of computer-controlled enemies (non-player characters; NPCs) in a player-vs-environment (PVE) battlefield, or (c) a very ...
This information includes the method name, the object that owns the method and values for the method parameters. Four terms always associated with the command pattern are command, receiver, invoker and client. A command object knows about receiver and invokes a method of the receiver. Values for parameters of the receiver method are stored in ...
