System D: A Distributed System for Availability
نویسندگان
چکیده
System D is a distributed transaction-processing system which addresses the problems of data integrity, system availability, and incremental growth. It is an experimental research vehicle and has been prototyped on a local network of loosely coupled minicomputers. This paper describes the architecture of the system. Novel features of System D include the distributed Resource Manager that provides high availability by diagnosing and taking corrective actions against software-induced crashes, the two-phase Direct Commit protocols that require fewer messages and I/OS than conventional two-phase commit protocols, the datagram-based communications architecture, and the modular storage system.

Performance Analysis of a Repairable Robot Safety System with Standby, Imperfect Coverage and Reboot Delay
The present study deals with a robot safety system composed of standby robot units and inbuilt safety unit. When the main operative unit fails, it is replaced by the standby robot unit available in the system. The concept of reboot delay is also incorporated in this study according to which the robot unit is rebooted if it is not successfully recovered. The recovery and reboot times of failed u...
متن کاملMathematical modeling and fuzzy availability analysis for serial processes in the crystallization system of a sugar plant
The binary states, i.e., success or failed state assumptions used in conventional reliability are inappropriate for reliability analysis of complex industrial systems due to lack of sufficient probabilistic information. For large complex systems, the uncertainty of each individual parameter enhances the uncertainty of the system reliability. In this paper, the concept of fuzzy reliability...
متن کاملReliability Analysis of Redundant Repairable System with Degraded Failure
This investigation deals with the transient analysis of the machine repair system consisting of M-operating units operating under the care of single repairman. To improve the system reliability/availability, Y warm standby and S cold standby units are provided to replace the failed units. In case when all spares are being used, the failure of units occurs in degraded fashion. In such situation ...
