A Monte-Carlo Approach to Lifespan Failure Performance Analysis of the Network Fabric in Modular Data Centers
Data centers have been evolved from a passive element of compute
infrastructure to become an active, core part of any ICT solution. In
particular, modular data centers (MDCs), which are a promising design approach
to improve resiliency of data centers, can play a key role in deploying ICT
infrastructure in remote and inhospitable environments in order to take
advantage of low temperatures and hydro- and wind-electric capabilities. This
is because of capability of the modular data centers to survive even in lack of
continuous on-site maintenance and support. The most critical part of a data
center is its network fabric that could impede the whole system even if all
other components are fully functional, assuming that other analyses has been
already performed to ensure the reliability of the underlying infrastructure
and support systems. In this work, a complete failure analysis of modular data
centers using failure models of various components including servers, switches,
and links is performed using a proposed Monte-Carlo approach. The proposed
Monte-Carlo approach, which is based on the concept of snapshots, allows us to
effectively calculate the performance of a design along its lifespan even up to
the terminal stages. To show the capabilities of the proposed approach, various
network topologies, such as FatTree, BCube, MDCube, and their modifications are
considered. The performance and also the lifespan of each topology design in
presence of failures of their components are studied against the topology
parameters.Comment: 29 Pages, 14 figure
