HP performance Evaluation for server Consolidation
Server consolidation has become an integral part of IT planning to reduce cost and improve efficiency in today's enterprise datacenters. The advent of resource virtualization allows consolidation of multiple applications into virtual servers hosted on a single or multiple physical servers. However, despite its salient features, this poses new challenges, including selection of the right virtualization technology and consolidation configuration for a particular set of applications. In this paper, we evaluate two representative virtualization technologies, Xen and OpenVZ, in various configurations. We consolidate one or more multi-tiered systems onto one or two nodes and drive the system with an auction workload called RUBiS. We compare both technologies with a base system in terms of application performance, resource consumption,scalability, low-level system metrics like cache misses, and virtualization-specific metrics like Domain-0 consumption in Xen. ………more
System management in Server based Computing with Virtualization
Server Based Computing (SBC) is a model where all the applications are installed, managed and executed on a server. Users’ computers are considered as thin clients that exchange keyboard, mouse and screen information with the server. Depending on the implementation, no actual programs are executed on the client machine……more
Applications of a Feather-weight Virtual Machine
A Feather-weight Virtual Machine (FVM) is an OS-level virtualization technology that enables multiple isolated execution environments to exist on a single Windows kernel. The key design goal of FVM is efficient resource sharing among VMs so as to minimize VM startup/shutdown cost and scale to a larger number of concurrent VM instances. As a result, FVM provides an effective platform for fault-tolerant and intrusion-tolerant applications that require frequent invocation and termination of dispensable VMs. This paper presents three complete applications of the FVM technology: scalable web site testing; shared binary service for application deployment and distributed Display-Only File Server (DOFS).…….more
