Book excerpt: This IBM® Redpaper® publication is a blueprint for configuration, testing results, and tuning guidelines for running SAS workloads on Red Hat Enterprise Linux that use IBM Spectrum® Scale and IBM Elastic Storage® System (ESS) 3000. IBM lab validation was conducted with the Red Hat Linux nodes running with the SAS simulator scripts that are connected to the IBM Spectrum Scale and IBM ESS 3000. Simultaneous workloads are simulated across multiple x-86 nodes running with Red Hat Linux to determine scalability against the IBM Spectrum Scale clustered file system and ESS 3000 array. This paper outlines the architecture, configuration details, and performance tuning to maximize SAS application performance with the IBM Spectrum Scale 5.0.4.3 and IBM ESS 3000. This document is intended to facilitate the deployment and configuration of the SAS applications that use IBM Spectrum Scale and IBM Elastic Storage System (ESS) 3000. The information in this document is distributed on an "as is" basis without any warranty that is either expressed or implied. Support assistance for the use of this material is limited to situations where IBM Spectrum Scale or IBM ESS 3000 are supported and entitled and where the issues are specific to a blueprint implementation.
