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.

Certified Hardware

Find a list of SAP-certified Dell hardware: 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
  • 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
  • DB2: SAP note 1130801
  • MaxDB: SAP note 1142243
  • Oracle: SAP note 1173954
  • SQL Server: Microsoft knowledge base article 956893

Performance Advice

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):
  1. Reboot your PowerEdge server.
  2. Enter your system BIOS by pressing F2.
  3. Chose CPU Information -> Adjacent Cache Line Prefetch.
  4. 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.
