Modeling and Availability Analysis of Internet Data Center With Various Maintenance Policies

In this paper, the authors have focused on the stochastic analysis of an internet data center (idc), which consists of a database main server connected to a redundant server. observing the different possibilities of functioning of the system, analysis has been done to evaluate the various reliability characteristics of the system. the system can completely fail due to failure of redundant server before repair of database server, router failure and switch failure. the system can also fail completely due to a cooling failure or some natural calamity like earthquake, fire; etc. all the failure rates are assumed constant while the repairs follow two types of distributions namely general and gumbel-hougaard family copula.
