The perils of downtime
IT organizations today are under pressure to keep a large number of complicated systems available for both employees and customers, 24/7. This is especially true for those systems that support business-critical applications and processes. For example, the SAP HANA* platform is commonly used across multiple industries to process data and transactions, and then run advanced analytics on them to deliver real-time insights. These are increasingly data-heavy, complex advanced analytics workloads like predictive or prescriptive analytics, and AI.
With so much riding on these systems operating reliably, any unforeseen downtime or admin mistakes (such as unplugging the wrong server during maintenance, or the power supply to the data center being interrupted) can have a big impact.
In these high-pressure situations, you need to get things back up and running as quickly as possible—for the good of the business and your own peace of mind. However, today’s increasing data volumes mean that re-starting a server or loading terabyte-scale databases into a traditional memory system can take hours (or even longer).
This is because a server’s main memory is typically volatile, meaning data is lost if the power supply is interrupted. It must then be loaded back into the memory before redundancy can be restored, creating more downtime. This is not only expensive, but it pulls database admins’ focus away from other important tasks.
SAP and Intel: A combined approach to optimizing advanced analytics workloads
Overcoming this challenge requires innovation in the way data is managed and stored, at both a database and a hardware level. Happily, recent developments by both SAP and Intel have aligned to enable a revolutionary leap forward in these capabilities.
Intel® Optane™ DC Persistent Memory represents an entirely new way of managing data for demanding workloads like the SAP HANA platform. It is non-volatile, meaning data does not need to be re-loaded from persistent storage to memory after a shutdown. Meanwhile, it runs at near-DRAM speeds, keeping up with the performance needs and expectations of complex SAP HANA environments, and their users.
At the same time, the latest version of the platform itself—SAP HANA* 2.0 SPS 03—contains innovations that are designed to enhance support for complex challenges like advanced analytics, development and data management. For example, it provides improved performance through parallel processing improvements for the training and scoring of predictive models, as well as high-availability and load balancing with TensorFlow* integration. When paired with powerful compute capabilities such as those provided by Intel® Xeon® Scalable processors, the platform can be further optimized.
Enterprises can now take advantage of these enhancements to rethink the way they approach data tiering and management. With more flexibility in how memory and storage are used, a number of compelling benefits for the IT team and the business emerge:
- Downtime is significantly reduced, with testing showing that restart time for SAP HANA 2.0 going from 50 minutes using traditional DRAM to just four minutes using Intel® Optane™ DC Persistent Memory—a 5x improvement.1
- Greater non-volatile memory capacity means more data can be analyzed at a time, helping speed time to results or decisions.
- Total cost of ownership for memory for an SAP HANA environment can be reduced by replacing expensive DRAM modules with non-volatile persistent memory.
- It’s now possible to place your entire storage area network (SAN)-based warm data tier in data modules that act like main memory, which helps boost performance for analytics and other complex workloads.
