Sometimes availability is expressed in qualitative terms. For instance, it might measure the extent to which a system can continue to work when a significant component or set of components is unavailable or not operating. System and software availability are measured by several different metrics. See...
Closed-form expressions are derived for the steady-state availability, mean rate of failure, mean duration of downtime and lower bound reliability of a general system with randomly and independently failing repairable components. Component failures are assumed to be homogeneous Poisson events in time ...
281-852-3749 hpaul@ Availability, reliability, maintainability, and capability are components of the effectiveness equation. The effectiveness equation is a figure of merit which is helpful for deciding which component(s) detract from performance measures. In many continuous process plants the reliabilit...
Coverage of most of Reliability, Availability, Maintainability, Risk and Safety analysis tasks by the wide range of RAM Commander modules RAMS engineer-oriented user experience necessary for system design Multi-user capabilities: simultaneous work on the same project for a number of users across the ...
The purpose of this paper is to describe the method used to calculate the Reliability and Availability estimations of the Uninterruptible Power Supply (UPS) systems using Monte-Carlo simulation method. In this method, the failure rates (λ), and availability (A) of the major components in the ...
System reliability depends not only on the reliabilities of components in the system but also on their interactions. Generally, in a system, not only s-ind... T Zhang,M Horigome - 《IEEE Transactions on Reliability》 被引量: 124发表: 2002年 The Availability and Reliability of Wireless Multi...
Availability analysis of repairable redundant system with three types of failures subject to common cause failure This paper deals with the availability analysis of a redundant system consisting of N-non-identical components and S warm standby components under the care...

High availability components and workflowTransaction completionApplication transaction-triggered writes and commits are first logged to the WAL on the primary server. These are then streamed to the standby server using the Postgres streaming protocol. Once the logs are persisted on the standby server ...
System availability is greatly enhanced by the ability to configure redundant components. All hot-swap components in the system can be configured redundantly, if the customer desires. Each system board is capable of independent operation. The Sun Fire 15K/12K systems are built with multiple system ...
Examine the potential high-availability capabilities of your application relative to your SLA, and identify where you have proper coverage and where you need to make improvements. Your goal is to add redundancy to components of the architecture so that you're less likely to experience an outage....
