What is Infiniband®?
Infiniband® is a network communication and storage system that uses high -speed serial links and processors to solve the performance and reliability for high -performance computer technology. It is able to reach 64,000 nodes and can provide speeds of up to 2.5 gigabites per second (GBPS). This speed is about 2,500 million bits per second (MBPS), which can download 1 gigabit file in less than 4 seconds. In early calculations, serial communication was considered too slow for fast data transfer and computer buses, which were mostly parallel, were the only choice. Fast serial links and serial buses are very practical and the points of hardware failure are smaller. For example, in a 32 -bit parallel bus, at least 32 sets of bit drivers are and most often pressure contacts connected between the interface cards. The probability of failure is then higher in the paral device in this regard.
Infiniband® also offers redundant for increased reliability. Storage Device and Hosts in Infiniband®They can be geographically distributed for optimized protection. For example, a massive database application that requires 24 x 7, or 100%can consider many techniques, including page redundancy, server redundancy and repository redundancy.
TheRedundance of the website replicates the entire website that acts at the same time as the main website of the application that may seem to be wasting computing and computer networks at first. Wisdom in the approach is observed when the operation at the point of primary application is partially or completely disrupted. The backup site that always works with the primary website is then promoted as the main site and constantly processes until the main site is active and online.
Redundance of Replicates Server Primary Server to ensure ongoing operation in case of failure. Whether coloring or remote from primary, secondary server can be in parallel operation so any major failureEating on the primary server disrupts the service. When mirroring the disk, the local server storage is written on two storage systems, while in the mirrors of the site, the backup website performs the primary server and synchronizes with it.
Connected textile communication link is able to supply the required overall width of the device zone of the necessary supercomputers. Fabric refers to a relatively huge network of hosts and network devices that are interconnected. In the switched substance, the remote high -speed storage and the fast remote host services are improved by switching technologies that reduce the overhead costs of computer technology and precipitation when data packets are sent to the network.
