Dell and SAP provide Competence Centers located in Austin (Texas), Walldorf (Germany), and Kawasaki (Japan) that serve as central points-of-contact for customers who want to run their SAP applications on Dell™ systems. Experienced engineers at these centers can provide custom sizings
of the best-suited platform architectures for your SAP implementation needs. Dell also conducts SAP benchmarks and publishes technical papers about SAP to assist its customers when deploying SAP software.

Similar to the certification there is
- An SAP Adaptive Compliance Test
You will only require this if you plan to use the ACC (Adaptive Computing Controller). More information on https://service.sap.com/adaptive.
- A HANA Validation
You want to virtualize your SAP environment? Here are some hints that have made life easier:
- SAP-supported virtualization solutions for X64 hardware are VMware, Xen and Hyper-V. Consider the SAP notes
* 1409608 for Windows: VMware and Hyper-V
* 1122387 for Linux: up to the hardware vendor. For Dell, VMware and Xen is supported, see Dell/SAP note 300900. Be aware that SAP only supports Xen from Novell, Red Hat and Citrix with limitations
- Consider your backup strategy
Do you use fibrechannel tape drives for your backups? Please consider that you cannot attach fibre channel cable to every virtual machine. There will soon be a solution from VMware for that, VMDirectPath.
- Consider your database
Do you want a virtualized database server? Do not forget some databases do not support virtualization or demand that you be able to reproduce a support issue on "bare metal". Info on

As discussed in the SAP Portal InfoBrief
, the prefetcher setting in the BIOS has a major influence on SAP performance. On ABAP, switching OFF the prefetcher (in a benchmark scenario) increased the system throughput (in Dialogsteps per second) by about 8 percent, and even more could be observed in Java-stack-based SAP software. To switch OFF the prefetcher (as in a Dell PowerEdge™ R900's example):
- Reboot your PowerEdge server.
- Enter your system BIOS by pressing F2.
- Chose CPU Information -> Adjacent Cache Line Prefetch.
- Set this option to "disabled."
Note: This option may also be called "Sequential Memory Access". It is not available on every server.
Setting HT Tech to HT 3 (where available) showed a performance increase of more than 10% in an SAP-specific load scenario. Here is an example from the PowerEdge M905:
Note: This performance hint was only tested in a 4-processor-configuration.
