  • Hi,

    Thank you for the post.

    You may perform the following steps to troubleshoot/nail down the root cause of the perf. Issues.

    1. Verify that SNP features (Chimney, RSS and NetDMA) are disabled on a Windows server2003 system

    More information is documented in KB articles

    948496 An update to turn off default SNP features is available for Windows Server 2003-based and Small Business Server 2003-based computers

    http://support.microsoft.com/default.aspx?scid=kb;EN-US;948496

    950224 A Scalable Networking Pack (SNP) hotfix rollup package is available for Windows Server 2003

    http://support.microsoft.com/default.aspx?scid=kb;EN-US;950224

    If all SNP features are deactivated already proceed with

    2. Update NIC driver + update NIC Teaming driver to the latest available version

    3. If step two makes no difference, break teaming, which is de-Installing the NIC teaming software.

    Regards,

  • If you disable teaming, does it still exhibit high queue lengths?

  • Thats one path we are planning to take though it hasnt been finalized. Dell PowerEdge 6850 & from what I am told by Dell tech support is that these servers are no longer manufactured so I am thinking that its EOL product (no Dell link/document available to verify this). The server is an active node in cluster environment & hosts SQL DB.
