    A toolkit for storage QoS provisioning for data-intensive applications

    This paper describes a programming toolkit developed in the PL-Grid project, named QStorMan, which supports storage QoS provisioning for data-intensive applications in distributed environments. QStorMan exploits knowledgeoriented methods for matching storage resources to non-functional requirements, which are defined for a data-intensive application. In order to support various usage scenarios, QStorMan provides two interfaces, such as programming libraries or a web portal. The interfaces allow to define the requirements either directly in an application source code or by using an intuitive graphical interface. The first way provides finer granularity, e.g., each portion of data processed by an application can define a different set of requirements. The second method is aimed at legacy applications support, which source code can not be modified. The toolkit has been evaluated using synthetic benchmarks and the production infrastructure of PL-Grid, in particular its storage infrastructure, which utilizes the Lustre file system.

    The dissertation proposes a concept a JIMS monitoring service, which is selfconfigurable, scalable, and equipped with elements of adaptability. The thesis is organised as follows. Chapter 1 contains the motivation for the dissertation, introduces key terms and contains the thesis statement. Chapter 2 is a critical survey of existing standards, technologies, and projects related to grid monitoring. Chapter 3 characterizes the grid as a whole, provides functional and non-functional requirements for the grid monitoring service and contains the thesis statement. The concept of the JIMS system, built according to the given requirements and assumptions, is described in Chapter 4. This chapter describes key solutions applied in the system, such as the component model and a uniform approach to resources representation, cluster- and grid-level self-configurability as well as elements of adaptability. The design and implementation details of this prototype are presented in Chapter 5. This chapter also introduces the concept of sensors for chosen elements of the grid infrastructure and middleware. Chapter 6 covers system evaluation and verification of results, where the author presents results of JIMS system usage in real grid installations and test results dealing with system intrusiveness, performance, and functionality. Chapter 7 presents results and summarizes the dissertation. The dissertation concludes with a list of common abbreviations, acronyms, definitions and indexed words, which should assist readers of this document.
