Understanding the Infrastructure Requirements of SAP HANA

Accurately sizing the infrastructure for HANA implementation is critical as it has a direct impact on both cost and performance.

Enabling the digital enterprise and developing business analytic solutions like SAP HANA are the key to understanding challenges and responding to them proactively. To develop successful strategies in today’s challenging environment, you need more access to critical enterprise insights than ever before. That fact is validated by a 2017 Gartner CIO Agenda survey which revealed analytics and enterprise resource planning (ERP) are top CIO priorities. In addition, Forrester estimate that 70% of data in the enterprise goes unused. Here is how you can understand the infrastructure requirements of SAP HANA.

It is of critical importance for buyers to make the right infrastructure choice while keeping an eye on costs at the same time. IT decision makers need to consider their existing and new infrastructure requirements, the architecture and design for SAP HANA and also choose the right migration strategy.

  • Infrastructure Requirements of SAP HANA
    The performance characteristics of SAP HANA are closer to the supercomputing world than to conventional IT environment. It’s also essential to remember that transferring enterprise data from disks to server RAM requires a fundamental rethink of infrastructure, especially the server. It requires a robust infrastructure that can run massive transactional & analytical workloads from the same underlying system. It needs high speed, multi-core, high memory servers with highest RAS capabilities. Hence, the processor power & memory capacity become critical.
  • Requires Performance, Reliability & Availability
    If the reliability and performance of the hardware infrastructure is not up to the desired level, it will put the whole HANA implementation into jeopardy. Similarly, the impact of outages affecting core ERP systems are quite well known. And real-time analytics systems are also proving to be equally sensitive to downtime. Hence, it is critical that the infrastructure is both highly reliable and available as even brief interruptions of service may impair decision making.
  • Should Be Scalable for Future Data Growth
    Scalability is another essential prerequisite for protecting investment, while optimising TCO. If the infrastructure has no built-in scalability, it can lead either to fragmented developments and increasingly complex IT setups or to wasted investment. Failing to take these measures upfront can lead to disastrous structural and financial impact. Hence, a successful HANA implementation depends on having the right SAP certified infrastructure that is scalable as per the needs of the organisation.

Overprovisioning the hardware means playing more for HANA license

  • Infrastructure Sizing
    In a SAP HANA implementation, it is critical that the infrastructure sizing is done correctly as the license fee on HANA is based on per GB of memory used in the hardware appliance. If the appliance is too big, buyers will end up paying extra for hardware and software, thus pushing up costs. And an appliance that’s too small may not meet the requirements, thus hampering the performance.
  • Architecture and Design
    While deciding on the infrastructure, buyers need to take into account the hardware architecture and design that will give maximum performance and scalability, while at the same time providing high reliability and availability. In a HANA environment, which combines both OLTP and OLAP systems, the need for high-availability architectures is even greater.
  • Keeping an Eye on Costs
    While the hardware infrastructure and software licensing costs account for a majority of the total costs, one can’t ignore the costs used to host the infrastructure. These include the datacenter costs for hosting the servers, the energy consumption of the IT equipment, and cooling costs which account for anywhere between 15 and 20 percent of the total cost over a three-year period. Overprovisioning the hardware means paying more for HANA license.
  • Migration
    Choosing the right migration strategy is a critical challenge as most existing SAP applications will require a database migration to HANA. Hence, buyers need to partner with someone trusted and who has the experience of having implemented such migration projects.
