Description: Topic: Reliability Analysis of Storage Area Networks with Cascading Failures

ZOOM Teleconference: https://umassd.zoom.us/j/98720525649

Abstract:
During the coronavirus pandemic, telecommuting is widely required, making remote data access grow significantly. This requires highly reliable data storage solutions. Storage area networks (SANs) are one of such solutions. To guarantee that SANs can deliver the desired quality of service, reliability modeling and analysis are crucial. A challenge to analyze the reliability of SANs is to address cascading failures that occur when a single initial incident (e.g., the malfunction of one device, overload, extreme weather) triggers a cascade of unexpected failures of other devices. The existing works of considering cascading failures have been mostly centered around traditional power systems and smart grids. In this work, we model the effects of cascading failures triggered by the data overload of devices in SANs. The proportional hazards model and accelerated failure time model are used to describe the relationship between the load and failure behavior of an SAN device. A detailed case study of a mesh SAN system is performed to illustrate the proposed method for the SAN reliability analysis considering cascading failures.
