SAP HANA Co-innovation for Real-Time Computing
For more than 10 years, Intel and SAP have worked together to deliver industry-leading performance of SAP solutions on Intel architecture, and a large proportion of new SAP implementations are now deployed on Intel platforms. The latest success from that tradition of co-innovation is available to customers of all sizes in the SAP HANA, which is fully supported only on the Intel Xeon® processor E7 family.
The relationship between Intel and SAP has become even stronger over the years, growing to include a broad set of collaborations and initiatives. Some of the most visible include the following:
Joint roadmap enablement. Early in the design process, Intel and SAP decision-makers identify complementary features and capabilities in their upcoming products, and those insights help to direct the development cycle for maximum value.
Collaborative product optimization. Intel engineers located on-site at SAP work with their SAP counterparts to provide tuning expertise that enables SAP HANA and other software solutions to take advantage of the latest hardware features.
Combined research eﬀorts. Together, researchers from Intel and SAP continually explore and drive the future of business computing. As a result of these eﬀorts, customer solutions achieve performance, scalability, reliability, and energy eﬃciency that translate into favorable ROI and TCO, for increased business value.
Operational Success and Management of Real-Time Events
In-memory computing based on SAP solutions on the Intel Xeon® processor E7 family enables greater business agility and innovative usage models that let companies respond to changing conditions in real time.
Scenarios such as monitoring customer and supplier activity can generate petabytes of data, the value of which depends on the ability to distill it into actionable intelligence.
SAP HANA and the latest Intel Xeon® processor E7 v2 family with up to 15 cores per socket deliver rapid data analysis that discerns patterns and trends, so you can adjust your just-in-time supply chain rapidly. You can also model “what if” scenarios to structure sales and promotions for optimal outcomes based on the latest sales and pipeline information.
Features of the Intel Xeon processor E7 v2 family, such as 37.5MB of L3 cache, Intel® QuickPath Interconnects, and quad-channel integrated memory controllers with the max memory speed of up to 1600MHz deliver extraordinary capabilities for businesses of all sizes that implement SAP HANA for functionality such as business intelligence and data analytics.
Especially the up to 24 DIMMs per socket with 64GB max DIMM density, which allow up to 6 TB in 4-socket, up to 12 TB in 8-socket or 24 TB in 16-socket servers provide SAP customers signiﬁcant improvements for large transactional workloads e.g. BusinessSuite on HANA.
Performance Optimizations of SAP HANA with the Intel Xeon® Processor E7 Family
SAP HANA beneﬁts dramatically from high-speed Intel® QuickPath processor-to-memory interconnects and the latest processor instructions, Streaming SIMD Extensions e.g. Intel® AVX. Those features eliminate many I/O bottlenecks, so processor headroom is available to generate excellent throughput and responsiveness. SAP HANA is also engineered to take particular advantage of RAS (reliability, availability, and serviceability) features of the Intel Xeon processor E7family, especially error correction through Machine Check Architecture Recovery, for mission-critical implementations.
As a result of the high level of performance optimization for servers based on the Intel Xeon processor E7 family, SAP HANA can provide businesses of all sizes with superior results for data warehousing implementations such as business intelligence and data analytics.
Assured Performance with Mission-Critical Advanced Reliability of the Intel Xeon Processor E7 Family
Machine Check Architecture Recovery, a reliability, availability, and serviceability (RAS) features built into the Intel Xeon® processor E7 family, enables the hardware platform to generate a Machine Check Exceptions. In many cases, these notiﬁcations enable the system to take corrective action that allows SAP HANA to keep running where an outage would otherwise occur.
Hardware based on the Intel Xeon® processor E7 family enables SAP HANA to fail over from one processor socket to another in the event of a processor failure and to handle memory errors with as little impact to workloads as possible.
Cisco Systems SAP HANA Solutions
As part of the “Uniﬁed Appliance Environment,” Cisco has developed a full portfolio of SAP HANA appliances based on Cisco Unified Computing System™ (Cisco UCS™) spanning from the smallest T-shirt sizing, supporting as low as 64 GB memory, up to large scale-out solutions which can support up to 8 TB of usable memory. Depending on the compression factors, the Cisco appliances can support databases up to 56 TB, the largest currently supported by SAP. However the Cisco technology can support up to 20 TB of usable memory, which corresponds to uncompressed databases up to 100 TB or more.
Cisco UCS: A Unique SAP HANA Solution
Cisco UCS is a single uniﬁed system entirely programmable through uniﬁed, model-based management to simplify and speed deployment of enterprise-class applications and services. All Cisco UCS SAP HANA appliances are intelligent infrastructure that can be managed through the embedded, single management plane across multiple Cisco UCS rack and blade servers (Figure 1). This radically simpliﬁes operations and lowers costs. The model-based management applies personality and conﬁgures server, network, and storage connectivity resources. Using Cisco service proﬁles, which deﬁne the model, it is simple to provision servers by applying a desired conﬁguration to physical infrastructure. The conﬁguration is applied quickly, accurately, and automatically, improving business agility, staﬀ productivity, and eliminating a major source of errors that can cause downtime.
The Cisco Fabric Extender Architecture reduces the number of system components to purchase, conﬁgure, manage, and maintain by condensing three network layers into one. It eliminates both blade server and hypervisor-based switches by connecting fabric interconnect ports directly to individual blade servers and virtual machines. Virtual networks are now managed exactly as physical networks are, but with massive scalability. This represents a radical simpliﬁcation over traditional systems, reducing capital and operating costs while increasing business agility, simplifying and speeding deployment, and improving performance.
Cisco UCS helps organizations go beyond eﬃciency: it helps them become more eﬀective through technologies that breed simplicity rather than complexity. The result is ﬂexible, agile, high-performance, self-integrating information technology that reduces staﬀ costs and increases uptime through automation, providing a more rapid return on investment.
The excellent performance combined with the broad range of usable memory makes the Cisco UCS SAP Appliances an excellent, easy-to-manage choice for analyzing massive amounts of business data.

SAP HANA T-Shirt Sizes Offered
The Extra Small (XS) and Small (S)-size appliances are based on the Cisco C260 M2 rack mount server with 2 Intel® Xeon® Processor E7-4870 (2.4 GHz) and up to 256 GB of usable memory for BW and 512 GB for SAP business suite on HANA. This conﬁguration is primarily used for development, test, and small production SAP HANA systems with uncompressed datasets up to 1.75 TB. The Cisco UCS appliance incorporates a persistency layer, based on internal SSD drives that require no additional drivers tainting the Linux kernel.
The Medium (M) -size appliance is based on the Cisco C460 M2 rack mount server with 4 Intel® Xeon® Processor E7-4870 (2.4 GHz) and up to 512 GB of usable memory for BW and 1024 GB for SAP business suite on HANA. This conﬁguration is ideal for use in mid-sized and larger production environments such as the one used by Medtronic, a large, worldwide manufacturer of medical devices. The persistency layer is provided by two Fusion IO cards to avoid possible bottlenecks in duo card configurations sharing the same PCI slot.
SAP HANA Scale-out offering
The Cisco UCS solution that has been certiﬁed for large SAP HANA implementations is a uniquely scalable appliance. It allows customers to easily adapt to the growing demands of their individual environment by incrementally adding Cisco B440 M2 blade servers with 4 Intel® Xeon® Processors E7-4870 (2.4 GHz) and up to 512 GB usable memory each, as needed. For every four Cisco UCS blade servers, the persistency layer is provided by an EMC VNX 5300 or a NetApp FAS 3240, depending on customer preference.
The “basic conﬁguration” of the Cisco scale-out oﬀering is made up of redundant fabric interconnects with embedded infrastructure management, a Cisco UCS C200 server for SAP HANA studio, a Cisco 2911 for secure remote management, and one enclosure with support for up to 4 Cisco B440 blades. The basic conﬁguration can easily scale by adding up by a literally inﬁnite number of Cisco B440 M2 blade servers each and the correspondent storage from EMC or NetApp. The beauty of Cisco’s scale out architecture that it can be extended by additional blades and storage units without shutting down the HANA system as we have proven at eBay, where an existing HANA system with 4 TB was extended to 12 TB on the ﬂy without any downtime.
High Availability SAP HANA Solution
Cisco UCS SAP HANA appliances have redundancy designed-in providing no single point of failure. However, in the event of a hardware failure on a blade or rack server, any spare Cisco UCS server can take over the role of the failed server in minutes by simply applying the service proﬁle to the spare server. Synchronous Disaster recovery (DR) scenarios up to 50km and asynchronous over inﬁnite distances can be easily implemented by using service proﬁles to quickly provision servers at the DR site in conjunction with the “classical” replication technologies of EMC and NetApp or the SAP HANA system replication feature.
SAP HANA Support infrastructure
All Cisco UCS servers are interconnected with a low-latency, high-bandwidth 10-Gbps uniﬁed Ethernet fabric. The uniﬁed fabric supports both IP and Fibre Channel over Ethernet (FCoE) connections through redundant, high performance, low-latency Cisco Fabric Interconnects. The Cisco Fabric Interconnect, with embedded management, is the core of the Cisco UCS and reduces both the number of network “hops” and network latency, critical to SAP HANA performance. The uniﬁed fabric radically reduces the number of cables, interchassis switches, and network adapters required by legacy platforms. This reduces energy consumption and operational costs resulting in much lower total cost of ownership.
The operating system, Cisco UCS drivers, and Cisco UCS management software are all part of the appliance; therefore no additional software is necessary to manage the entire system. However Cisco Intelligent Automation for SAP HANA is highly recommended. The Cisco Intelligent Automation software solution supports the daily operation of a SAP HANA appliance by:
- Monitoring the CPU and memory workload, and the average index read time at the blade level
- Automating quarterly maintenance, including ﬁrmware updates and ﬁle system validation
- Ensuring conﬁguration management assurance for all appliance components
- Monitoring data services availability
- Proactively monitoring SAP HANA subsystem components status
- Monitoring query execution response times using the SAP HANA index for the query execution SAP HANA Query Response Time
- Executing sample queries and recording total execution time and query component performance breakdown
- Proactively monitoring the SAP TREX services statistics based on thresholds
- Alerting CPU, memory, or throughput thresholds for SAP TREX services
- Automating Cisco UCS blade and rack server provisioning for use in the appliance in minutes, instead of days

Customer Success Story
Customer testimonials can act as very powerful marketing content and messaging.
Medtronic dramatically improved reporting performance, increasing the value of its customer information, with the SAP HANA™ platform and Cisco Uniﬁed Computing System™ (Cisco UCS™) server platform.
Medtronic needed to increase its ability to analyze large amounts of data, such as customer feedback. BI reporting on its fast-growing data warehouse was straining the capabilities of the company’s computer infrastructure. Because employees couldn’t generate some types of reports (particularly using unstructured data), their ability to draw conclusions from existing data was limited.
The company deployed the SAP HANA platform on the Cisco UCS server platform based on the Intel® Xeon® processor E7 family. In preliminary testing, users of an “un-tuned” system observed query times just one-third as long as those with existing production systems. With the fully scaled and optimized implementation now in place, Medtronic hopes to cut response times even further.
BI operations at Medtronic will use the SAP HANA platform to report on structured and unstructured data, wherever it resides, whether on SAP or non-SAP systems. The added performance, scalability, and ﬂexibility of this new architecture will increase the value of company data as it continues to proliferate, increasing employee eﬃciency and enabling the smarter decision making.
