Network throttling doesn't work RRS feed

  • Question

  • We have DPM 2007 setup across a WAN.  I would like to throttle the bandwidth usage during the day.  I've researched a good bit and think I have it all setup correclty.  However, when it backs up during the day (which occurs occasionally due to failures or other reasons), it is transferring at the fastest possible rate.  This is bringing my remote office user productivity to a standstill during working hours.

    Here's the setup:

    • DPM 2007 server on Windows Server 2008 Standard.  Protection Agent Version: 2.0.8844.0.  Protected servers are also Windows 2008 Standard.
    • Throttle Computer under Management is set to 128Kbps during hours of 8am to 5pm Monday through Friday.  I have non-work hours set to 9999Mbps.  I do not have this reversed in any way and I am sure of this because often backups will complete overnight and they wouldn't be able to do this over 128Kbps.
    • NICs are Intel PRO/1000 PT Dual port adapters. I put this NIC on the DPM server because I found that it supports 802.1p (where the onboard Broadcom adapters do not seem to support that protocol.  These NICs are also used on the 2 protected host servers (some VMs are using the Broadcom adapters, though).
    • For all NICS (protected and DPM server) QoS Packet Scheduler is enabled.
    • I have tested various combinations of NICs and virtual machines to backup.  All is with the same result of maximum bandwidth usage and no throttling.

    As I have spent countless hours on this issue and irritated my remote office exceedingly, I covet words of wisdom. 

    Thank you.
