Bandwidth maxed out at 10 MB/s



  • New to Fog. I have a virtual Ubuntu 12.04 server on VMware ESXi 5.0.0 hosting Fog. The server is 1000 MB/s to the switch and 100 MB/s out to the computers to be imaged. I have been able to pull and image and push it out to another computer. When I pushed out to a group of 4 computers I notice slow progress with an image time of 7+ hours at 63 MiB/min, I did not take not but I think the single image was going at 400+ MiB/min. The Fog Dashboard Transmit Bandwidth is maxed out at 10 MB/s. Is there a configuration setting someplace I missed that would allow faster transmit speeds to a group of computers?

    [SIZE=3][FONT=Times New Roman][COLOR=#000000]I assume it was Multicast. I did it from Group Management - Basic Tasks - Deploy.[/COLOR][/FONT][/SIZE]

    [SIZE=3][FONT=Times New Roman][COLOR=#000000]I did resolve it this morning by putting the computers to be imaged on the same gigabit switch as the ESXi server and its guest servers. I don’t have much control over the network configuration so why there was such a drastic difference when I had the computers to be imaged off another 100 MB switch further down the line is not much of a concern. Most of the time we get a batch of new computers in and image them before deploying them to other sites. The occasional reimage will be OK at the slower speed.[/COLOR][/FONT][/SIZE]

    How did you push out to the systems? Unicast or Multicast?

    i think you will find that the problem is somewhere in your network configuration. I run virtual Ubuntu 12.04 server on VMware ESXi 5.0.0 with gigabit to the clients, and i get 3GiB/min to the client. ~400 to the server from client, but that’s mainly compression slowing it down.
