High availability (HA) is a characteristic of a system that aims to ensure an agreed level of operational performance, usually uptime, for a higher than normal period. [ 1 ] There is now more dependence on these systems as a result of modernization.
OpenHPI is an open-source software system providing an abstracted interface to managing computer hardware, typically for chassis and rack based servers. [1] [2] It is production ready implementation of the Hardware Platform Interface specification from Service Availability Forum, complimenting existing hardware management standards.
High-availability clusters (also known as HA clusters, fail-over clusters) are groups of computers that support server applications that can be reliably utilized with a minimum amount of down-time. They operate by using high availability software to harness redundant computers in groups or clusters that provide continued service when system ...
In information technology, high-availability application architecture is a process followed when implementing a new application into an existing business-wide computer system or ERP while minimizing downtime. ff The architecture contains three stages: development, quality assurance, and production.
High availability is a high percentage of time that the system is functioning. It can be formally defined as (1 – (down time/ total time))*100%. Although the minimum required availability varies by task, systems typically attempt to achieve 99.999% (5-nines) availability.
