A growing concern among corporate information technology (IT) managers is the elevating gap between the increasing system maintenance and administration cost of the IT infrastructure and the decreasing hardware/software acquisition cost. This gap is escalating because system administration and management is still heavily labor-intensive and does not scale very well with system size and complexity, despite extensive research efforts to automate the process. One promising approach to drastically reduce this cost is to adopt a computing utility model, in which a centrally managed computing infrastructure is shared among multiple enterprise applications in a way that preserves their high-level business objectives. The primary technical challenge in the computing utility model is how to provision and schedule system resources to support the desired quality of service (QoS) of individual business applications that share the same physical infrastructure without human intervention. This project proposes to develop a multi-dimensional resource virtualization system called Iguacu, which multiplexes multiple system resources among a set of enterprise applications on a large-scale PC cluster such that the delay and/or throughput requirement of each such application is satisfied. Iguacu features three key innovations. First, unlike most previous QoS efforts that focus on a single system resource, Iguacu coordinates the allocation and scheduling of multiple system resources, including CPU, disk, and network link, to meet application-specific QoS requirements while significantly improving individual resource's utilization efficiency. Second, Iguacu supports a unified and reusable implementation framework that could quickly convert, with zero or minor modification, a given database-intensive enterprise application into a form that provides guarantees based on service-specific performance metrics. The development of such a framework greatly mitigates the efforts required to deploy QoS-aware enterprise applications in a complicated IT environment. Third, Iguacu features a novel procedure that automatically translates high-level QoS specifications into physical system resource requirements for distributed enterprise applications running on a cluster environment.Besides its intellectual contributions, this project is expected to make a major impact on the undergraduate and graduate education of the Computer Science department at Stony Brook University by introducing a series of system management and administration courses, which will use the Iguacu prototype as a case study on the functionality and implementation details of an enterprise-scale system management system for scalable PC clusters. Finally, the technologies developed in this project are expected to influence the future product directions of a major system management solution vendor, Computer Associates International, through an on-going research collaboration in the network/system management area.

公司信息技术（IT）管理人员日益关注的是，IT基础设施的系统维护和管理成本不断增加，而硬件/软件采购成本不断下降，两者之间的差距越来越大。这一差距正在扩大，因为系统管理和管理仍然是劳动密集型的，并且不能很好地扩展系统的规模和复杂性，尽管广泛的研究工作，以自动化的过程。一个有希望的方法，以大幅降低这一成本是采用计算实用程序模型，其中集中管理的计算基础设施之间共享的方式，保持其高层次的业务目标的多个企业应用程序。计算实用模型中的主要技术挑战是如何提供和调度系统资源以支持共享相同物理基础设施的各个业务应用的期望服务质量（QoS），而无需人为干预。本项目提出开发一个多维资源虚拟化系统Iguacu，它在一个大规模的PC集群上的一组企业应用程序之间复用多个系统资源，以满足每个应用程序的延迟和/或吞吐量要求。伊瓜苏有三个关键的创新。首先，与以前大多数专注于单个系统资源的QoS努力不同，Iguacu协调多个系统资源（包括CPU，磁盘和网络链路）的分配和调度，以满足特定于应用程序的QoS要求，同时显着提高单个资源的利用效率。其次，Iguacu支持一个统一的、可重用的实现框架，它可以快速地将给定的数据库密集型企业应用程序转换为一种形式，这种形式可以基于特定于服务的性能指标提供保证，而不需要进行任何修改或进行微小的修改。这样一个框架的开发大大减轻了在复杂的IT环境中部署QoS感知企业应用程序所需的工作。第三，Iguacu的特点是一个新的过程，自动转换高层次的QoS规范到物理系统资源需求的分布式企业应用程序运行在集群环境中。除了其智力贡献，该项目预计将作出重大影响的本科生和研究生教育的计算机科学系在斯托尼布鲁克大学通过介绍一系列的系统管理和行政课程，它将使用Iguacu原型作为案例研究，研究可扩展PC集群的企业级系统管理系统的功能和实施细节。最后，在这个项目中开发的技术预计将影响未来的产品方向的主要系统管理解决方案供应商，国际计算机协会，通过正在进行的研究合作，在网络/系统管理领域。
