Multi site Fog deployment



  • I have some questions on the proper way to configure Fog to work in a multi site setup. We have one main campus that includes three buildings all on the same subnet 10.0.0.0. Then we have 20 branches that are on 192.168.x.x third octet is the branch ID then the fourth being the range of IP’s given out to machnes.

        I setup Fog to replace a botched Ghost install that has been running for five years or so and only images machines at the helpdesk. We are mainly a windows shop and DHCP scopes are controlled here at the main campus for all branches. My thoughts after reading the forums on how I can set this up so we can image from a local storage node at each location would be to set them up as TFTP/PXE and point the scope for each location to the local storage node and leave the client on each machine configured to the main Fog server at the main campus.
    
        Will this allow us to control the imaging process from the main Fog server while only pushing images and Snap-ins from the local storage node? If there are steps to control the local machines so that they will accept commands from the main server while only pull images from the local node I'm not seeing any but if you guys could point me in the right direction I would be very grateful. Fog is the best free solution I have ran across and you guys kick ass.
    

    Sorry for the wall of text. I try to remember to format it for easy reading next time.



  • Can someone point me in the right direction please? I cannot find any help on this, basically I am new to fog and Linux, I have been tasked with deploying fog, we have 4 sites all on extremely slow links so would like to have the main fog server at head office and a storage node at each site, when a client pxe boots it needs to look at the database at head office for task assignments but pull the images from its local storage node, is there a numpty’s guide to acheive this please?



  • Well since your using a flat network you could try this multi site patch. Lee is the man on this but the downside is you have to .031 for it to work as there are changes to the coding on .032 that keep this from working. So long story short you create locations and tie them to FOG servers with each computer then add the secondary FOG servers to the main FOG server as part of the default storage group and use DHCP to control which FOG server the computers boot from and the location make the computer pull from that machine.

    Then you can setup the replication to happen in off hours or throttle it so that the link between the two sites isn’t overloaded. Look this over and hit me up or ask Lee since he made the patch and hes really nice and walked me through getting it hammered out.



  • Well we have two sites but no router (all on the subnet)
    So the network see’s it as one.

    I wanted to add a 2nd server into our setup because the pipe between sites is 100Mps.
    if we where to image site 2, this would render then useless.

    Did think of just adding another FOG server and having done with it. But then due to them using the same DHCP they would boot off the site 1 FOG. we would have to amend DHCP record when we wanted to use site 2. Did find a link http://www.fogproject.org/wiki/index.php/Multiple_TFTP_servers

    But that seems to do a lot of sync. we are trying to reduce bandwidth.

    Any idea’s?



  • Yes with the help of Lee and his Multi site setup I have my 26 branches running off FOG and deploying software to all of them with snapins.



  • how did you chaps get on with this?



  • There is this information here: http://www.fogproject.org/wiki/index.php/Multiple_TFTP_servers[/B]

    I tried it, but am having some trouble, so if you found something that worked for you, I would be glad to hear about it.

    You’re posts would be easier to read and understand, and thus more likely to get a response if you organized it into paragraphs. Right now it’s just a wall of text and is very off putting.
