[1] [2] [3] By utilizing device-mapper, the multipathd daemon provides the host-side logic to use multiple paths of a redundant network to provide continuous availability and higher-bandwidth connectivity between the host server and the block-level device. [4] DM-MPIO handles the rerouting of block I/O to an alternate path in the event of a ...
Multipath TCP (MPTCP) is an ongoing effort of the Internet Engineering Task Force's (IETF) Multipath TCP working group, that aims at allowing a Transmission Control Protocol (TCP) connection to use multiple paths to maximize throughput and increase redundancy.
Multipath access to a RAID using Linux DM Multipath (Legend: "HBA" = Host bus adapter, "SAN" = Storage area network). In computer storage, multipath I/O is a fault-tolerance and performance-enhancement technique that defines more than one physical path between the CPU in a computer system and its mass-storage devices through the buses, controllers, switches, and bridge devices connecting them.
Linux Mint began in 2006 with a beta release, 1.0, code-named 'Ada', [13] based on Kubuntu and using its KDE interface. Linux Mint 2.0 'Barbara' was the first version to use Ubuntu as its codebase and its GNOME interface. It had few users until the release of Linux Mint 3.0, 'Cassandra'.
Modern Linux distributions include a /sys directory as a virtual filesystem (sysfs, comparable to /proc, which is a procfs), which stores and allows modification of the devices connected to the system, [20] whereas many traditional Unix-like operating systems use /sys as a symbolic link to the kernel source tree.
A 32-bit PC BIOS will search for boot code on an ISO 9660 CD-ROM. The standard allows for booting in two different modes. Either in hard disk emulation when the boot information can be accessed directly from the CD media, or in floppy emulation mode where the boot information is stored in an image file of a floppy disk , which is loaded from ...
XDP (eXpress Data Path) is an eBPF-based high-performance network data path used to send and receive network packets at high rates by bypassing most of the operating system networking stack. It is merged in the Linux kernel since version 4.8. [2] This implementation is licensed under GPL. Large technology firms including Amazon, Google and ...
By contrast, any failure along a series path causes the entire series path to fail. [2] [3] An RBD may be drawn using switches in place of blocks, where a closed switch represents a working component and an open switch represents a failed component. If a path may be found through the network of switches from beginning to end, the system still ...
