In this paper, two storage area networks (SANs) extension scenarios are proposed in a wide area wavelength division multiplexing (WDM) mesh architecture. While in the first scenario storage resources are assumed to be located in two nodes serving as primary and secondary SANs, storage resources are assumed to be distributed over a number of nodes serving as primary and secondary SANs in the second...
This paper presents a new data mirroring technique for storage area networks (SANs) in a metropolitan area wavelength division multiplexing (WDM) ring. Two sectioning links are introduced to the ring to help deal with the hot-node scenario created by the SAN nodes and their mirrors. The performance is evaluated through simulation of a network of 24 nodes, 6 wavelengths with 1 Gb/s access node rate...
First-generation storage area networks (SANs) were designed to operate within limited distances. However, with the destructive effects of catastrophic events in a limited distance environment and the need of large organizations to connect their campuses over large geographic distances to share storage recourses among a larger number of users, the need of extending SANs has become essential. Several...
