3,990 | A Redundant Array of Inexpensive Servers (RAIS) or Redundant Array of Independent Nodes (RAIN) is the use of multiple servers to maintain service if one server fails. This is similar in concept to how RAID turns a cluster of ordinary disks into a single block device. RAIS was designed to provide the benefits of a symmetric multiprocessor system (SMP) at the entry cost of computer clusters | Redundant Array of Inexpensive Servers |
3,991 | In computer networking, Rate Based Satellite Control Protocol (RBSCP) is a tunneling method proposed by Cisco to improve the performance of satellite network links with high latency and error rates.
The problem RBSCP addresses is that the long RTT on the link keeps TCP virtual circuits in slow start for a long time. This, in addition to the high loss give a very low amount of bandwidth on the channel | Rate Based Satellite Control Protocol |
3,992 | In computing, the term raw disk, often referred to as raw, is used to refer to hard disk access at a raw, binary level, beneath the file system level, and using partition data at the MBR.
A notable example is in the context of platform virtualization, and a feature of certain virtualization software is the ability to access a hard disk at the raw level. Virtualization software may typically function via the usage of a virtual drive format like OVF, but some users may want the virtualization software to be able to run an operating system that has been installed on another disk or disk partition | Rawdisk |
