An Introduction to SAN Capacity Planning
نویسنده
چکیده
Emerging technology that allows the construction of high performance storage area networks (SANs) requires extending existing analytic frameworks that can accurately predict the performance of complex disk subsystems. This paper focuses specifically on two elements of emerging SAN technology: (1) the performance of Fibre Channel links and connecting hubs and switches, and (2) the performance of in-band and out-of-band SAN data management protocols. Traces and timings from benchmarking tests conducted with an in-band SAN data manager product are analyzed and discussed. Understanding this measurement data should enable existing disk modeling approaches to be extended to encompass this new storage technology.

متن کاملSANFS Maestro: Resource Planning for Enterprise Storage Area Network (SAN) File Systems
Manual planning of storage infrastructures that are large and that utilize heterogeneous devices has become a time consuming and error prone process. This problem becomes even more complex when one is designing storage area network file system (SAN FS) based storage solutions. SAN FS systems that combine the benefits of both SAN and network attached (NAS) systems have been proposed as a mechani...

متن کاملCapacity planning in the hospital queueing network with blocking: simulation-based optimization approach
Introduction: Hospital administrators have always faced the challenge of providing the best possible health services in a resource-limited environment. The patient flow throughout the hospital is affected by lack of the capacities that can lead to bed-blocking among the hospital units. In this research, the patient flow in the hospital is modeled as an open queueing network with blocking. Then,...
متن کاملPolicy Capacity Is Necessary but Not Sufficient; Comment on “Health Reform Requires Policy Capacity”
Policy capacity focuses on the managerial and organizational abilities to inform policy decisions with sound research and analysis, and facilitate policy implementation with operational efficiency. It stems from a view of the policy process that is rational and positivistic, in which optimal policy choices can be identified, selected, and implemented with objectivity. By itself, however, policy...
