Assessing Server Fault Tolerance and Disaster Recovery Implementation in Thin Client Architectures

摘要

This thesis will focus on assessing server fault tolerance and disaster recovery procedures for thin-clients being implemented in smart classrooms and computer laboratories aboard the Naval Postgraduate School campus. The successful discovery of fault tolerance limits and a disaster recovery plan not only benefits the Naval Postgraduate School (NPS), but also provides the same for other commands that have implemented or plan to employ thin clients as part of their Information Technology (IT) infrastructure. Since the backbone of thin client/server-based computing (TCSBC) is the reliance on the server as the hub of processing power and data storage, it is imperative that some plan to restore the server be effected to save from the loss of valuable data. In the case of NPS, the absence of the main server not only contributes to data loss, but deprives students of hours of invaluable classroom instruction. The fault tolerance issues and disaster recovery solutions addressed in this thesis may not be suitable in all thin client architectures, but perhaps the knowledge gained can aid some commands in avoiding a catastrophic server failure.
