Optimize Your SAP HANA Deployment with Scalable, Flash-Based Storage

How Flash Technology Is Transforming SAP HANA Economics and Performance

Enterprises can deploy SAP HANA infrastructure in a number of ways, but need to balance cost, complexity, and performance to determine which solution is right for their SAP HANA use case. As their SAP HANA capacity requirements increase, they need an architecture that can keep up with their growing needs while also maintaining cost-effective transaction performance. Read this article to discover how deploying SAP HANA on a shared storage architecture is simple, cost effective, and fast.

 

Enterprises are increasingly considering flash technology as a way to improve their data centers. SanDisk has been helping customers transform their data centers by flash-enabling databases and other transactional workloads to create greater levels of technical and cost efficiencies and drive higher application performance and densities. Adding the right flash in the right places is key to optimizing not just performance, but also reliability and scale. This is good news for SAP HANA environments, which are ripe for this type of optimization.

Working with SAP, SanDisk has created a portfolio of products that help enable enterprise customers to deploy high-performance infrastructure for SAP applications and scalable systems. A primary focus for this partnership has been the SanDisk ION Accelerator appliance, an SAP-certified all-flash appliance that provides unique capabilities for deploying highly scalable, high-performance SAP HANA deployments as part of the SAP HANA tailored data center integration offering. The SanDisk ION Accelerator appliance allows enterprises to use storage area network (SAN) architectures for SAP HANA for centralized data management processes such as data center backup and disaster recovery. Shared storage is useful to consider as a way to move log and data volumes off of individual SAP HANA appliance nodes as a shared resource. Let’s look at SAP HANA tailored data center integration in more detail, and what it means for your infrastructure options.

Provided that the server and storage systems are SAP certified, SAP HANA tailored data center integration enables customers to meet their deployment requirements in a more flexible manner than was previously thought possible.

What Is SAP HANA Tailored Data Center Integration?

SAP HANA began as a clustered appliance model that required that the server, software, networking, and storage were all contained within an SAP HANA node. These nodes could then be scaled across multiple appliances as the SAP HANA database capacity requirements increased, with data shared across the cluster.

With SAP HANA tailored data center integration, SAP HANA software can now be deployed across multiple SAP HANA nodes while moving the persistent storage to an external set of certified storage solutions. This architecture allows customers to tailor their SAP HANA infrastructure to use existing and new SAN infrastructure and introduces flexible deployment options for SAP HANA infrastructure. With more choice and flexibility, companies are no longer limited to a small set of options.

Provided that the server and storage systems are SAP certified, SAP HANA tailored data center integration enables customers to meet their deployment requirements in a more flexible manner than was previously thought possible.

While this flexibility can increase the complexity of the overall installation, deployment, and management of SAP HANA infrastructure, it can also simplify data management processes by taking advantage of shared storage resources and existing data management policies. Companies deploying SanDisk ION Accelerator appliances with SAP HANA tailored data center integration can dramatically reduce the per-node storage costs while also ensuring high transactional performance.

A single pair of SanDisk ION Accelerator appliances deployed in a high availability configuration, each using as few as four units of rack space, can meet the required performance for up to 32 SAP HANA nodes. The precise number of SanDisk ION Accelerator appliances required to support a given SAP HANA configuration is a function of the memory size of each SAP HANA node and the number of such nodes deployed in an SAP HANA cluster, but with up to 32 nodes supported on one high availability pair, deployments of multiple terabytes of SAP HANA database can easily be achieved with plenty of room for growth — and without additional cost (see Figure 1).

Speed and Reliability

The all-flash SanDisk ION Accelerator appliance has been designed from the ground up to focus on high-performance, efficiency, and highly scalable shared storage. It offers up to:

  • 1.7 million input/output operations per second (IOPS)
  • 56 microsecond access latency
  • 23 gigabits per second of bandwidth for OLTP (transactional) and OLAP (analytics) workload acceleration

This makes the SanDisk ION Accelerator appliance one of the fastest options for SAP HANA tailored data center integration deployments and ensures maximum performance for SAP HANA data management, including transaction logs that can be a bottleneck for performance.

Depending on the configuration, a SanDisk ION Accelerator appliance can contain up to 51.2 terabytes of flash storage, controlled by four storage processors and optimized for throughput, bandwidth, and ultra-low latency. The SanDisk ION Accelerator appliance can be deployed in a high availability clustered pair, providing additional data integrity and protection with redundancy at the component, appliance, and software levels.

Scalability

With the SAP HANA enterprise storage certification, the SanDisk ION Accelerator appliance is one of the fastest, most reliable, and most scalable shared storage platforms for SAP HANA databases.1 Supporting up to 32 SAP HANA nodes on a single SanDisk ION Accelerator appliance high availability pair, it is possible to deploy multiple terabytes of SAP HANA database capacity and leverage the performance of the SanDisk ION Accelerator appliance for all data snapshots, transaction logs, and shared file system resources.

This means you can deploy your current SAP HANA workloads on a minimal number of SanDisk ION Accelerator appliance pairs and even have room to scale your SAP HANA compute nodes without having to deploy additional shared storage. The SanDisk ION Accelerator appliance provides fast overall transaction speeds, especially for write-intensive transactional workloads, fast recovery from SAP HANA node failures, while maintaining overall performance and reliability for your SAP HANA environment.
