Also, if you do choose to use multi-cast you really can't use cheap switches. We tried it with some and they totally choked. There is some overhead they need to process and the cheap switches really didn't have the guts to handle it.

I have been able to image 10-12 machines at a time on a 1GB link with a cheap switch (small backplane) with no issues, as during the 30-40 minute imaging process, data is only being transferred for a small portion of it. By the time you get all of the machines launched and running, where they are in the process is usually staggered enough that you only have 1-2 downloading the WIM file at any given time.

I've found the results to be less than stellar. Others said the same thing at the time we tried using this. Mark Kent (MCP) Sr. Desktop Systems Engineer Computing & Technology Services - SUNY Buffalo State From: [email protected]<mailto:[email protected]> [mailto:[email protected]] On Behalf Of Corkill, Daniel Sent: Wednesday, February 3, 2016 6:22 PM To: [email protected]<mailto:[email protected]> Subject: [mssms] Setting up multicast I'm looking into implementing multicast on all DPs where PXE is enabled. So far I'm reading the following information: http://blogs.technet.com/b/charlesa_us/archive/2015/06/25/setting-up-multicasting-in-configmgr-2012.aspx https://technet.microsoft.com/en-us/library/hh397406.aspx Some questions I have for those who have implemented it: 1. Are there any recommendations/best practices for the maximum clients and transfer rate settings? 2. Autocast vs scheduled - I'm leaning towards autocast because my understanding is that with scheduled in place, I won't be able to image single machines (unless I decrease the scheduled start delay to 2 mins or something like that). 3. After implementing it, if I'm imaging two, three, four machines at once, how do I verify multicast is actually being used? Any other guidance people who have implemented it can recommend? Any gotchas? Daniel. ********************************************************************* This email, including any attachment, is confidential to the intended recipient.
