Today, roughly 75 percent of SAP software installations are deployed on Intel® processor-based servers, including many large enterprise implementations. In most cases, these implementations are deployed on relatively large numbers of distributed four-socket or smaller servers. How can this install base benefit from the latest technology trend, including more powerful hardware, virtualization, and lower-cost open source operating systems?

SAP co-innovation Lab has just completed a PoC with 4 partners, HP, Intel, SUSE (a business unit of the Attachmate Group), and VMWare to investigate on this topic. The findings are documented in a 5 company joint whitepaper (link:  http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/e0eb1f0b-15b6-2e10-69ad-f5f54c43222c?quicklink=index&overridelayout=true )   

The paper describes key hardware and software advances that are especially relevant for supporting mission-critical SAP software deployments, as well as the key results of the COIL PoC.   The following figure shows the high level deployment architecture of the COIL enviroment.

scalability

The PoC showed Near-linear scalability for a heavy ERP workload deployed to virtual machines (VMs) running on a single physical server. A two-socket server based on the Intel Xeon processor 5600 series was shown to support up to 2,100 concurrent users
with an average response time of less than one second. An eight-socket HP ProLiant™ DL980 server based on the Intel Xeon processor 7500 series was able to support
up to 8,000 concurrent users with a sub-second average response time.

scalability: 2 vs 8 sockets

Much more details about the environment, the test setup, and the results are available in the paper. Check it out, and let us know what you think.

    Kevin,

    set up 15 SAP instance, including Production[PI711 and ERP604] on RHEL5.5 + MaxDB7.7/7.8 on VMWareESX4.1 last year on IBM H/w + storage. Still running smooth, with a little hiccup on the I/O side “very rarely” by keeping close to 1TB.

    Would you tell, the storage vendor for this PoC. I see there were multipath options mention in the doc for DL980.

    I read it as a more of XEON75xx series intro to the virtual side; though we have 8vCPU/VM.

    What I wonder here in this PoC setup, we don’t even get one 75xx “Physical-CPU’s” value per VM; say for a 1TB+ DB in a distributed installation. This is Super “Process” virtualized for 176GB or just after installation DB plus CI VM.

    Thanks!

      Thanks for the comments, Vipin.

      Our storage vendor is NetApp.

      in the case of the 8-socekt server tests, only the CI+DB has 176GB RAM and 8vCPU, all the DIs were allocated 4vPCU and 16 GB RAM.

      Best Regards,
      Kevin
