SAP on Power

IBM Power servers are purpose built for data-intensive applications such as SAP HANA and S/4HANA that require large amounts of in-memory computing but still let you maintain the high availability and flexibility required for your hybrid cloud.

SAP removed HANA on POWER restrictions for vPMEM and shared processor pool support

By Walter Orb posted 05/17/21 10:56 AM

  
SAP has updated the following two notes and removed the previous restrictions for running SAP HANA on Power Systems in a shared processor pool LPAR and the usage of virtual persistent memory (vPMEM):

2188482 - SAP HANA on IBM Power Systems: Allowed Hardware

2055470 - HANA on POWER Planning and Installation Specifics - Central Note


You can now run all SAP HANA workloads (OLAP, OLTP, and mixed workloads) in a shared processor pool LPAR up to the maximum size of the system, as for example 16 sockets on an E980.

The restriction that vPMEM was limited to 8 sockets has been removed as well.

These changes now allow you to exploit the full flexibility of Power Systems to run your HANA systems in a dedicated or shared pool LPAR configuration that fits your business needs.
