Would Snap Deploy Multicasting bog down Network for 1 PC ?

Thread needs solution

Should I use Unicast if Imaging 1 PC on the Domain ? Will Multicasting bring down the Network ?

Is it best to Image on a seperate switch for just a few PC's?

What is everyone is doing ?

Thanks,

Joe

Hello Joe,

Thank you for using [[http://www.acronis.com/enterprise/ | Acronis Corporate Products]]

Just to be sure that we are using the same terms: multicast and unicast modes are related to the deploy (not for the backup) operation.

With the Multicast transfer mode, Acronis OS Deploy Server sends data to a group of recipients simultaneously. Using the Unicast transfer mode, the server sends a copy of the data to each recipient (this can significantly reduce the deployment speed.) For example, you have 128 KB/sec bandwidth and want to deploy a system on 10 target computers.
- With Unicast mode, the server divides 128 KB/sec among 10 computers, therefore the data transfer speed will be 12.8 KB/sec for each target machine.
- With Multicast mode, the server sends one copy of data to a multicast address, and each client will receive data at 128 KB/sec speed.

Since you want to deploy the image to a single or a few computers, you should leave the default, multicast value.

Thank you.

I have 200PC but i never deploy all at the same time (only about 70-80 at a time). Multicasting causes the rest of the network backup to a crawl as the multicast packets are getting sent to every PC on my network including the ones i am not deploying to. How do i go about preventing this from happening. Unicasting is not an option for me as my master image is over 130GB.

For the time being i am unicasting till i can figure this out. Just unicasting 20PC at a time takes about 8hrs.

Hello Viet Duong,

Thank you for using Acronis Corporate Products

Acronis Snap Deploy has the ability to disable deployment on computers with specified MAC addresses (Mac filtering). The disabling (exclusion) list has to include all computers that are not allowed to be the deployment targets. Deployment through any network interface that is not in the list will be permitted.

The option can be found when editing the default options only.

If this doesn't help, could you please let us know if your hardware is IGMP-capable? Acronis Snap Deploy uses Internet Group Management Protocol (IGMP) for the multicasting.

Thank you.

LOL go with unicast its slower but you wont take your network down !! It will come to a crawl with Multicasting from Acronis !
Or you can stick with Mulitcasting and setup filtering like Oleg suggested but I think its still going to flood your LAN !

This seems to be an issue has anyone else come across a faster fix for this?

We are still seeing this being an issue has anyone come up with a solution to allow multicast?

We have set up Dell Latitudes D830 with MULTICAST and MAC address filtering and I am doing 2 machines right now and it is going to take over an hour to drop the image. I am on a Gig port why is this taking so long. When I do a standard deploy it only takes about 20 minutes. Is there something we can do to speed this up?
