What is SAP HANA Hardware
Recommended by 0 users
SAP HANA is delivered as a ﬂexible, multipurpose appliance that combines SAP software components optimized on hardware provided by SAP’s leading hardware partners such as Cisco, Dell, IBM, HP, Hitachi, NEC, and Fujitsu, using the latest Intel Xeon E7 processors. SAP HANA servers are sold in “t- shirt” sizes ranging from Extra-Small (128GB RAM) all the way up to Extra Large (>2TB RAM). Because RAM is the key technology for SAP HANA, SAP uses the amount of RAM to determine the server’s t-shirt size as well as its price. SAP’s underlying philosophy is “the more processors (cores), the better,” so it does not impose a per-processor charge for SAP HANA.
With the current certiﬁed Scale-Out options from SAP HANA hardware providers, companies can deploy up to 16 Extra Large server nodes into on logical database instance, which equates to a maximum of 32TB of RAM and 128 CPUs with 1280 total cores. SAP is currently testing a 60 node SAP HANA instance in the labs.
The hardware vendor provides factory pre-installation for the hardware, the OS, and the SAP software. It may also add speciﬁc best-practices and conﬁguration. The vendor ﬁnalizes the installation with on-site setup and conﬁguration of the SAP HANA components, including deployment in the customer data center, connectivity to the network, Solution Manager setup, SAP router connectivity, and SSL support. The customer then establishes connectivity to the source systems and clients, including the deployment of additional replication components on the source system(s) and, potentially, the installation and conﬁguration of SAP BusinessObjects business analytics client components.
Although the term “appliance” suggests a “black box” that plugs into an outlet, in reality installing SAP HANA requires on-site activities and coordination on a high technical level. The appliance approach for SAP HANA systems reduces the implementation and maintenance eﬀort signiﬁcantly, but it does not eliminate it completely. Furthermore, as of SP7, SAP HANA can be deployed in another way, through the SAP HANA tailored data center integration, which is aimed at large customers with a substantial investment in storage.
SAP HANA Use Cases
Because SAP HANA is both a database (in the traditional sense) and a database platform (in the modern sense), it can be used in multiple scenarios and deployed in several ways. SAP HANA performs equally well for analytic and transactional applications. Due to its hybrid table structure, however, it really shines in scenarios that involve both types of data. It’s important to remember that SAP has developed SAP HANA to be a non-disruptive addition to existing landscapes. With this point in mind, we’ll discuss the key use cases that are most typical for SAP HANA deployments today, and we’ll consider some potential future scenarios.
In its current form, SAP HANA can be used for four basic types of use case: agile data mart, a primary database for the SAP Business Suite, a primary database for SAP Business Warehouse, and a development platform for new applications. As SAP HANA matures and SAP renovates its entire portfolio of solutions to take advantage of all the horsepower in SAP HANA, you can expect to see nearly every product that SAP provides supported natively on SAP HANA as a primary database, as well as many more new “native-HANA” applications.
For a listing of hundreds of permutations of these core use cases and details on current SAP HANA live customers by industry and function, please visit the SAP HANA Use Case Repository.
Agile Data Mart
A data mart is an industry term for a repository of data gathered from operational data originating in transactional systems (and/or other sources), designed to serve a particular community of information workers by forming a basis for analytics, reporting, or a specific use in another type of application. The emphasis of a data mart is on meeting the specific needs of a particular group of users in terms of analysis, content, presentation, and ease-of-use.
The earliest scenarios where SAP HANA has been deployed in production are as a stand-alone data mart for a speciﬁc use case. In this scenario, SAP HANA acts as the central hub to collect data from a few SAP and non-SAP source systems and then display some fairly simple and focused analytics in a single-purpose dashboard for users.
This use case has the advantages of
(1) being completely non-disruptive to the existing landscape and (2) providing an immediate, focused solution to an urgent business analytics problem.
These projects are also typically completed very quickly, sometimes in just a few weeks, because the business problem is well known and the relevant data and source systems are easily identiﬁed. SAP HANA is set up as a stand-alone system in the landscape, which is then connected to the source systems and displayed to a small number of users in a simple Web-based or mobile user interface. This process involves zero disruption to the existing landscape, and companies get instant value because they can now do things that were impossible before they acquired SAP HANA.
Additionally, the development cycles for these use cases are typically very short, because most of these scenarios use a standard SAP BusinessObjects front end with self-service analytics or Microsoft Excel. We label these systems as “agile data marts” because they perform a few of the same functions as a traditional data mart — ETL, data modeling, analytic front end — but they are very fast to set up and flexible to use.
The key advantage of SAP HANA for the agile data mart scenarios is that these scenarios were either completely impossible to build in a traditional database architecture or they were so cost prohibitive that companies could not justify building them. The scenarios might be straightforward, but the deficiencies of the “old” database world made them “unfixable.”
You can access the videos listed below to listen to a few highly satisﬁed customers talking enthusiastically about their agile data mart scenarios with SAP HANA.
Nongfu Spring, the largest producer of bottled water in China, has successfully gone live on the largest customer implementation of the SAP HANA platform in China.
SAP provides a special licensing bundle to build an agile data mart use case with SAP HANA that includes the extractors and connectors needed to obtain data from source systems and the front-end tools needed to build analytical applications on top of the data.
SAP Business Suite
The second major scenario where SAP HANA is being used is to accelerate transactions and reports inside the SAP Business Suite.
SAP Business Suite software, a set of fully integrated applications such as SAP ERP, SAP CRM, SAP SCM, and SAP SRM, enables enterprises to run their core business operations more efficiently.
As of mid-2013, SAP HANA can now be used as the primary database under every application in the SAP Business Suite (excl. SAP SRM). SAP HANA can be set up as either a stand-alone system in the landscape, side-by-side with the database under the SAP Business Suite applications or as the primary database for the entire SAP Business Suite. In this scenario, however, SAP HANA is being used to “oﬀ load” some of the transactions or reports that typically take a long time (hours or days) to run, but it is not being used as the primary database under the application.
We explained earlier that certain transactions or reports inside the SAP Business Suite can be very slow, primarily due to the slow I/O of the disk- based database underneath the system and the huge requests for data generated by these transactions and reports. Budgeting and planning transactions in SAP require the system to call data from many diﬀerent tables in order to run its calculations and present a result. Reports are also very data-intensive, involving vast amounts of data contained in multiple tables. For both transactions and reports, then, the application must request the data from the database, load it into a buﬀer table in the SAP application server, run the algorithm or calculation, and then display the results. Sometimes, that completes the process. Other times, however, the user needs to make some adjustments to the results and then save the changes back to the database. Quite often, this process is iterative, meaning that the user must run the report or transaction, review the results, make some changes, and then run the report or transaction again to reﬂect the changes. Imagine a scenario where every time the transaction or report runs, it takes one hour to ﬁnish (from when you press “Enter” until the results are displayed on the screen). What if it took several hours or even a day or two to run that transaction or report? Clearly, system latency can seriously slow down the entire company.
Eliminating System Latency: The Case of Hilti
To illustrate severe system latency, let’s consider the case of Hilti, the global construction tools manufacturer. Hilti is used to generate a list of 9 million customers from 53 million database records in its SAP ERP system in about three hours. A salesperson used to hit “Enter” and then return three hours later to obtain the results. Signiﬁcantly, 99% of the time the system took to generate that list came from simply retrieving the records oﬀ the disk-based database. Once the data were conveyed to the SAP application, the algorithm only took a few fractions of a second to calculate. This major — and unnecessary — delay was the epitome of “latency.”
To eliminate this latency problem, Hilti set up an SAP HANA system next to their production SAP ERP system and then copied the relevant tables into SAP HANA. The results? Hilti can now run the exact same report in about three seconds. In addition, installing SAP HANA was totally non-disruptive. It required no changes to the algorithm, no changes to the production database, and no changes to the user interface. In fact, the users didn’t even realize there had been any change to the system until they ran the report for the ﬁrst time. They expected the process to take several hours — as always — so they got up from their desks to do something else. To their complete surprise, the completed report appeared on their screen before they could get out of their chairs.
Technically, there is very little that needs to be done to accelerate a few problematic transactions or reports in an SAP Business Suite application. In summary, SAP has already delivered the content for most of the truly problematic transactions and reports as part of the latest service packs for the SAP Business Suite — for free. Once the relevant tables have been replicated to the SAP HANA system, there is a quick change in the conﬁguration screen to redirect the transaction to read from the SAP HANA database instead of the primary database — and that’s about it. Users log in as they normally do, execute the transaction or report, and the results come back incredibly fast. SAP has also set up special ﬁxed-price, ﬁxed-scope SAP rapid deployment solutions (RDS) to assist customers in the rapid implementation of these “accelerated” transactions and reports.

SAP HANA is the ﬁrst SAP solution that has been built to be speciﬁcally run as an appliance and optimized for a very speciﬁc combination of processor, memory, and operating system. This approach represents a departure from SAP’s long history of broad platform support. SAP implemented this new policy to still provide customers with multiple choices in hardware platforms while avoiding the TCO implications of multiple OS and processor support combinations. In order to understand why, we need to look back historically at some of the hardware platform changes that led SAP to adopt this policy, this strategy and explore why this path oﬀers SAP customers the best balance of broad hardware partner options and focused innovation around a stable set of key components.
When SAP shifted from mainframe to client-server architecture with SAP R/3, two of the critical beneﬁts were the lower costs and the more standardized options associated with the UNIX-based servers that had just become available. When the mass-adoption of SAP R/3 took oﬀ, customers began asking SAP to certify more and more new combinations of operating system and database on various hardware platforms. This made sense because many companies were employing existing landscapes from a preferred hardware vendor and had developed expertise in certain versions of operating system and database that they wanted to leverage for their SAP environment.
SAP happily obliged, building out a robust certiﬁcation laboratory in its headquarters to constantly test and validate new hardware and software combinations that were being released by its partners for customer use. At the time, SAP believed that providing customers with such a broad choice would help them achieve lower TCO of their SAP solutions by reusing technology and resources that were already in place. SAP also felt that being the hardware and OS/DB “agnostic” would be the best strategy to set itself apart from the other enterprise app vendors. This “technology-neutral” strategy worked very well for SAP for more than 30 years. At a certain point in the mid-2000s, however, the small number of combinations that SAP began with had exploded into a truly dizzying collection. Customers no longer beneﬁted signiﬁcantly from such a broad list of hardware and technology choices, and the costs for SAP and its customers of this broad coverage was becoming unsustainable.
After SAP R/3 was released, the UNIX platform began to splinter into multiple dialects, with each hardware vendor putting its eﬀorts behind its preferred variant (HPUX, AIX, Solaris, etc.). In addition, x86 platforms from Intel and AMD began to displace the RISC-based platforms of the early UNIX hardware vendors due to their lower costs and their support for industry standards. Later, Linux began to displace the original UNIX operating systems due to its lower costs and the advantages of open-source code. Soon, the Product Availability Matrix (PAM) for SAP ERP exceeded 200 combinations of OS and database, with a vast number of hardware platforms for those combinations. At a certain point, the choice became a liability for SAP and its customers rather than the benefit that it was originally intended to be.
So, when SAP began development on the precursors of SAP HANA, the company made a strategic decision to avoid all of the costs and complexity of supporting so many variations of hardware and technology platforms. SAP was primarily concerned with the three pieces of technology that had the greatest impact on performance and would be the largest drivers of TCO reduction: operating system (OS), RAM, and processors. SAP decided to bet on open-source and industry standards as the core platform for SAP HANA. By supporting only ONE combination of OS and processors, SAP could invest all its development and testing resources into a single platform while still allowing customers to choose which hardware vendor would deliver and support the appliance.
SAP had been working with Novell/SUSE for many years to support Novell SLES Linux as a certiﬁed operating system for SAP applications. Because Linux is so technically similar to UNIX, almost any UNIX engineer could transition his or her skills easily. Moreover, because Linux was open-source and easily supported by third parties, it was clearly the lowest TCO option for running an SAP system.
In addition to selecting a single OS, SAP had to settle on a single processor family for the new solution. Although there were many chips on the market that could handle SAP’s traditional application-processing requirements, there weren’t any processors that had been designed to handle in-memory processing tasks (because enterprise-scale in-memory computing didn’t exist yet). The initial SAP HANA conversations that SAP’s executives held with anyone outside the company were with Intel because SAP realized that shifting to in-memory computing would require a new breed of processors that were optimized for the new architecture, and Intel has a long history of innovating for the future needs of the enterprise.
SAP laid out its strategy for the shift to in-memory computing to Intel’s executives, and the two parties discussed the level of co-innovation that would be needed to jointly engineer both an in-memory database and optimized processors that could handle the unique needs of this new architecture. The top executives from each company agreed that then they would have to establish a new level of co-innovation partnership and starting in 2005, Intel sent a team of their best software and chip engineers to SAP HQ to begin the work of jointly optimizing each successive version of the industry-standard Intel Xeon chips for the needs of SAP’s evolving in-memory database. Since that time, SAP has beneﬁtted from early access to each new generation of Xeon processor from Intel, and Intel has incorporated SAP’s unique in-memory processing requirements into its chip capabilities.
Intel and SAP: A History of Co-Innovation
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 SAP HANA, which is delivered on the Intel® Xeon® processor.
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:
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 translates into favorable ROI and TCO, for increased business value.
Having created an optimized “core” (operating system, RAM, and processors) for SAP HANA, SAP needed to reach out to the server manufacturers to package the software and hardware into industry-standard appliances in a way that would remove as much conﬁguration and integration work from the customers as possible (again, lowering TCO). SAP realized that even though the core components of the SAP HANA servers would be nearly identical (OS, RAM, and processors), the hardware vendors provide a great deal of additional value in the implementation, management and operations of the hardware. Plus, customers typically have a preferred hardware vendor for their enterprise landscapes. This is really where SAP felt that customer choice would have the most value. So, they engaged seven of their primary hardware vendors (see the next paragraph) to build certiﬁed SAP HANA appliances and create packaged services to implement SAP HANA quickly and easily at customer sites.
In early 2011, Cisco, Dell, Fujitsu, IBM, and HP all jumped on the SAP HANA bandwagon and had their ﬂagship Intel-based servers certiﬁed and in production. Hitachi joined the list later that year, and NEC was certiﬁed in early 2012. Huawei, VMC and Lenovo joined in 2013. This broad support from industry-leading hardware vendors provide customers with a choice of seven hardware partners to deploy their SAP HANA solution, each with unique service and support oﬀerings to ﬁt their customers’ needs. SAP’s strategy of “solid core,” multivendor hardware support for SAP HANA has been received extremely well by customers because it eliminates the confusing number of hardware combinations and focuses on the value-added solutions that each vendor can offer on top of the “solid core.”
In May of 2013, SAP made a major step forward in providing an even lower cost, higher-value deployment option for customers by announcing the SAP HANA Enterprise Cloud. The SAP HANA Enterprise Cloud oﬀering is a comprehensive RAM-optimized cloud infrastructure combined with managed services. Customers can now run their SAP HANA applications, including SAP Business Suite powered by SAP HANA and SAP Business Warehouse powered by SAP HANA, in a managed cloud environment. It delivers the power of real- time in-memory technology with cloud simplicity and elastic economics.
SAP HANA Enterprise Cloud is a fully scalable, enterprise-ready, mission critical, secure, and high availability cloud oﬀering with a fully-managed services approach.
