SAP HANA on … #ChooseRight

Window of Opportunity

IBM Power systems started late in the SAP HANA market, on standby if you will when IBM still had their System X business. Once they sold off their x86 business, it opened the door for IBM to work with SAP to offer clients a 2nd platform choice especially with many ECC shops coming from Enterprise platforms and now their only option is to deploy their most critical business application on Intel.

With thousands of clients running SAP ECC using Oracle or DB2 on AIX or running IBM I, there is a large and experienced install base. IBM’s move to support Linux little endian natively beginning with POWER8 eased any development concerns SAP may have had. IBM Power has been fastest adoption for a platform after the initial SAP Ramp-up Program.

Rapid Growth

After the initial Ramp-up program, SAP announced the first GA of HANA for IBM Power in 2015. Since then, it has been the fastest adopted platform by clients to run SAP HANA.

Whether deploying a Greenfield or Brownfield SAP HANA solution, what makes IBM Power such a better platform for SAP HANA over Intel based systems? It starts with its DNA. IBM Power was born an Enterprise system, in the data center running mission critical workloads. Read the Forrester Total Economic Impact of IBM Power Systems for SAP HANA study how they rate the platform.

Clients will deploy fewer systems, while able to host more workloads per system, whether those are legacy SAP ECC, SolMan or non-SAP workloads such as legacy Oracle workloads or possibly new Cognitive workloads.

Bringing it ALL together

SAP HANA; whether Suite or BW on HANA or S/4HANA or BW/4HANA, businesses tend to focus on the application, discounting the infrastructure as commodity – it’s all the same. With SAP HANA, designed as a scale-up in-memory technology, IBM Power is the optimal platform to host it.

  • Primary benefits such as fewer systems with greater utilization.
  • Secondary benefits such as less infrastructure and data center services required, i.e. fewer network & SAN ports, fewer power plugs with lower electrical consumption requiring less to cool.
  • Tertiary benefits, often more difficult to quantify such as the downtime the business did NOT have to take to perform a maintenance action such as updating firmware or adding an adapter for additional capacity.
  • Other actions such as downstream activities impacting the I/O paths like a network switch service event can all be accommodated with a properly architected and deployed Power solution.

These foundational capabilities allow the business to remain on schedule, consultants continue to work and not be idle.

#ChooseRight

There are only two options for SAP HANA. One option is the platform forcing you to choose one feature for another making every decision a compromise. The other option is the platform offering complete flexibility, scalability and resiliency with no compromises as even IDC states in this whitepaper. No one wants to go back to their board asking for more money admitting they made a mistake, undersized or failed to anticipate something, so #ChooseRight!
