SAP Application Server certified instances on IBM Power Virtual Server
SAP Application Server certified instances on IBM Power Virtual Servers are available with fully adjustable CPU Cores and Memory (RAM GiB). It is permitted to define a custom size of the IBM Power Virtual Server instance to use for SAP Application Servers or SAP NetWeaver, in accordance with existing SAP Application Server, SAP NetWeaver or SAP AnyDB for IBM best practices and guidance from SAP.
For SAP applications the following virtual server configurations are supported. Flexible SAP Application Server certified instances on IBM operate in SMT8 mode. Simultaneous Multithreading (SMT) on IBM Power enables multiple independent threads to execute within a single physical processor core. In SMT8 mode, eight parallel threads can run on a single physical processor core. The operating system sees eight logical processors per physical processor core. Given SAP Application Server instance sizing is flexible, it must follow the standard SAP sizing guidelines by using the following SAPS benchmark calculation:
| Power System type | SAPS per CPU Core (using SMT-8) |
|---|---|
| S1022 | 7,600 |
| E1080 | 7,600 |
| S922 | 5,570 |
| E980 | 6,000 |
SAP NetWeaver certified instances on E1050 are currently not supported.

Predefined SAP Application Server instances on IBM Power Virtual Servers
SAP Application Server certified instances on IBM Power Virtual Servers are also available as predefined configurations. A predefined SAP Application Server certified instance or profile on IBM Power Virtual Server defines attributes, such as physical CPU cores and RAM, which determine the size and performance capabilities of the virtual server instance.
SAP Application Server Profile Naming Convention
SAP Application Server profile names follow a contextual and sequential naming convention. The following table illustrates an example of an SAP Application certified instance profile:
| Profile name | Naming convention component | Description |
|---|---|---|
| sr2-2x32 | sr2 | Profile prefix |
| - | separator | |
| 2 | 2 physical CPU Cores | |
| x | separator | |
| 32 | 32 GiB RAM |
sr2 – Predefined SAP Application Server Profiles
The following predefined SAP Application Server profiles with prefix sr2 on IBM Power Virtual Server are available. Profiles with sr2 prefix are custom profiles that may be deployed through CLI or API only.
| Profile name | CPU cores | Virtual CPUs | Memory (GiB) | SAPS | SMT Mode | Workload Type |
|---|---|---|---|---|---|---|
| sr2-2x32 | 2 | 16 | 32 | 15,200 | SMT8 | SAP Application Server/SAP NetWeaver |
| sr2-3x64 | 3 | 24 | 64 | 22,800 | SMT8 | SAP Application Server/SAP NetWeaver |
| sr2-4x64 | 4 | 32 | 64 | 30,400 | SMT8 | SAP Application Server/SAP NetWeaver |
| sr2-6x128 | 6 | 48 | 128 | 45,600 | SMT8 | SAP Application Server/SAP NetWeaver |
| sr2-8x128 | 8 | 64 | 128 | 60,800 | SMT8 | SAP Application Server/SAP NetWeaver |
| sr2-12x256 | 12 | 96 | 256 | 91,200 | SMT8 | SAP Application Server/SAP NetWeaver |
| sr2-16x256 | 16 | 128 | 256 | 121,600 | SMT8 | SAP Application Server/SAP NetWeaver |
