Understanding the Performance Implications of PAVs and Multiple Allegiances for Storage Subsystems
نویسنده
چکیده
Abstract: This paper presents the results of a paired-sample evaluation of the benefits of parallel access volumes (PAVs) and multiple allegiances for reducing logical volume IOSQing delays. A simple back-of-the-envelope technique is provided for estimating the potential performance benefits of moving an existing workload to an IBM 2105 Enterprise Storage Subsystem or other storage subsystem which implements these features.

The present system of thermal plant under study consists of four subsystems with...
متن کاملBenchmarking storage subsystems at home using SPC tools
Storage vendors routinely benchmark their products in a lab for marketing or internal development. Realizing enterprise storage procurements can run into the millions of dollars, how can an end user organization evaluate various storage subsystems in their environments before signing on the bottom line? Using Storage Performance Council (SPC) benchmarks, this organization tested multiple storag...
متن کاملAvailability Optimization of a Series Repairable System with Multiple k-out-of-n Subsystems
An availability model is developed to optimize the availability of a series repairable system with multiple k-out-of-n subsystems in this paper. There are two types of decision variables that determine the system designer’s decision to allocate the number of repairmen and to allocate the number of redundant components in each subsystem in the presence of weight, volume and cost constraint...
متن کاملMulti-Objective Optimization of Solar Thermal Energy Storage Using Hybrid of Particle Swarm Optimization and Multiple Crossover and Mutation Operator
Increasing of net energy storage (Q net) and discharge time of phase change material (t PCM), simultaneously, are important purpose in the design of solar systems. In the present paper, Multi-Objective (MO) based on hybrid of Particle Swarm Optimization (PSO) and multiple crossover and mutation operator is used for Pareto based optimization of solar systems. The conflicting objectives are Q net...
