Authors: Olaf Weiser
SAP HANA on IBM® POWER® is an established HANA solution with which customers can run HANA-based analytic and business applications on a flexible IBM Power-based infrastructure. IT assets, such as servers, storage, and skills and operation procedures, can easily be used and re-used instead of enforcing more investment into dedicated SAP HANA only appliances.
In this scenario, IBM Spectrum Scale™ as the underlying block storage and files system adds further benefits to this solution stack to take advantage of scale effects, higher availability, simplification, and performance.
With the IBM Elastic Storage™ Server (ESS) based on IBM Spectrum Scale, RAID capabilities are added to the file system. By using the intelligent internal logic of the IBM Spectrum™ Scale Raid code, reasonable performance and significant disk failure recovery improvements are achieved.
This IBM Redpaper™ publication focuses on the benefits and advantages to implement a HANA solution on top of IBM Spectrum Scale storage file system.
This paper is intended to help experienced administrator and IT specialists to plan and setup an IBM Spectrum Scale cluster and configuring an ESS for SAP HANA workloads. It provides important hints and best practices about how to manage IBM Spectrum Scale’s availability and performance.
If you are familiar with ESS, IBM Spectrum Scale, and IBM Spectrum Scale RAID and you need only the pertinent documentation about how to configure an IBM Spectrum Scale cluster with an ESS for SAP HANA, see Chapter 5, “IBM Spectrum Scale customization for HANA” on page 27.
Before reading this IBM Redpaper publication, you should be familiar with the basic concepts of IBM Spectrum Scale and IBM Spectrum Scale RAID.
This IBM Redpaper publication can be helpful for architects and specialists who planning an SAP HANA on POWER deployment with the IBM Spectrum Scale file system. For more information about planning considerations for power, see the SAP HANA on Power Planning Guide.
