Data Set Allocation and Performance Management Under System Managed Storage
نویسنده
چکیده
Abstract: System managed storage (SMS) redefines data set allocation for the MVS operating system and provides new data set level performance management capabilities that exploit advanced cached control unit functionality. Unfortunately, the algorithms and measurement data sources that support these DFSMS functions are poorly defined in the available documentation. This tutorial will provide a detailed description of the execution of ACS (Automatic Class Selection) routines, SRM (System Resources Manager) interface, device selection, volume free space management, inter-system communication, data set level caching and interfaces with the 3990-3 control unit.

Evaluation of Object Placement Techniques in a Policy-Managed Storage System
Storage management cost is a significant fraction of the total cost of ownership of large, enterprise storage systems. Consequently, software automation of common storage management tasks so as to reduce the total cost of ownership is an active area of research. In this paper, we consider a policy-managed storage system—a system that automates various management tasks—and focus on the problem o...
متن کاملStorage Allocation for Multi-Class Distributed Data Storage Systems
Distributed storage systems (DSSs) provide a scalable solution for reliably storing massive amounts of data coming from various sources. Heterogeneity of these data sources often means different data classes (types) exist in a DSS, each needing a different level of quality of service (QoS). As a result, efficient data storage and retrieval processes that satisfy various QoS requirements are nee...
متن کاملPolicy-Based Autonomic Storage Allocation
The goal of autonomic storage allocation is to achieve allocation of storage resources, their performance monitoring, and hotspot elimination by specifying comparatively high-level goals, rather than by means of low-level manual steps. The process of automation should allow specification of policies as administrator specified constraints under which the resources are managed. This paper describ...
متن کاملStudy of the performance of a solar adsorption cooling system
This article presents a transient model of a solar adsorption cooling system. A computer program has been developed to simulate the operation of a two bed silica gel- water adsorption cooling system as well as flat plate collectors and the hot water storage tank. This program is then utilized to simulate the performance of a sample solar adsorption cooling system used for cooling a set of r...
متن کاملOASIS: Self-tuning Storage for Applications
This paper introduces OASIS, a self-tuning storage management architecture that allows applications and the storage environment to negotiate resource allocations without requiring human intervention. The goal of OASIS is to maximize the utilization of all the storage resources in the storage area network subject to fairness in the allocation of resources to applications. To achieve this goal, O...
