Abstract:
Storage Area Networks (SANs) have become an essential part of today's enterprise computing. SAN technologies are starting to be widely ~sed for data backup, recovery, and storage consolidation. INSTANT is a DTI-funded collaboration between two British universities: the University of Wales Swansea and the University of Cambridge and one industrial collaborator, ALPS. The principal objectives of the project are to devise a new form of fibre based high capacity distributed, dynamic, reconfigurable SAN and to enhance the performance and reconfigurability of the network using recently developed low cost Wavelength Division Multiplexing (WDM) technologies. In this thesis, we present results relating to a new metro WI?M storage demonstrator project, the INtegrated STorage Area NeTwork (INSTANT). Comprehensive literature review on SANs and WDM technologies was conducted. Based on the reviews, we propose novel SAN architecture and MAC protocols for SANs in metro WDM networks setting. Several possible solutions are proposed: storage area networking with fixed packet size, with variable packet size based on the real IP datagram distribution and with sectioned ring. \Ve then discuss and evaluate the network performance of the MAC protocol utilised in the proposed architectures. Performance analysis in real world scenarios and under realistic network traffic is performed. Two different traffic models were developed and implemented to simulate realistic traffic patterns. Both symmetric and asymmetric traffic scenarios are considered. Network performance in terms of throughput, delay and packet dropping probability are presented and studied. A novel data mirroring technique for metro WDM SANs in ring network architectures is also proposed and evaluated. Finally, traffic statistics in metro WDM SANs is also studied and discussed. Our approach considers all traffic happening during the conversation as a unique bidirectional flow of data, which we divided into upstream and downstream traffic. We separately study upstream and downstream traffic, building for each of them, estimates of number of packet and packet's inter-arrival time (IAT).
