Protect Your SAP HANA Investment with HA and DR Options

Implementing an SAP HANA system involves more than just selecting a standalone server. Organizations must also consider the different options available in terms of high availability (HA) and disaster recovery (DR). Depending on the organization’s service level requirements, multiple servers, storage devices, backup devices, and network devices might be required. This article gives an overview of the different ways organizations can achieve SAP HANA HA and DR. Equipped with this information, you can develop the right SAP HANA architecture and business continuity strategy more easily.
Learning Objectives

Reading this article you will learn:

  • How to maintain high availability (HA) in SAP HANA
  • The disaster recovery (DR) options in SAP HANA
Key Concept

True SAP HANA high availability (HA) requires a scale-out configuration or system-to-system replication. System backups are critical to both the recovery and health of your SAP HANA system.

SAP HANA’s architecture has revolutionized how software, hardware, and in-memory storage can be combined to eliminate many of the data management issues that have historically plagued businesses and organizations. Introduced in 2010, it can serve as both an online transaction processing (OLTP) and online analytical processing (OLAP) engine in a single platform, which allows SAP HANA to operate an ERP system and simultaneously provide operational analytics to ERP users.

Because it holds data in-memory, data processing tasks are completed much faster when compared with relational databases that rely on disk drives for storage. SAP HANA can store data in a columnar orientation to bolster the speed of analytic queries and reduce the storage footprint of repeated column values. Because of these speed advantages, scalable real-time query access to data is a reality with SAP HANA. For many organizations, SAP HANA can meet data management needs by reducing data management complexity while simultaneously granting users actionable access to their data.

As organizations begin to adopt SAP HANA, it is important to take a moment to review its capabilities in the areas of high availability (HA) and disaster recovery (DR). If an organization fails to properly plan for SAP HANA business continuity, many of the excellent features of SAP HANA will be overshadowed if they cannot maintain its availability or provide recovery during a disaster. I provide you with an overview of the different HA and DR options that are available with SAP HANA as of Support Package stack 10 (SPS10). There are many options available. As I explain these options, my hope is that you discover a solution that accommodates the service level agreements (SLAs) that have been established by your organization.
