Hi

We have Cisco 2960 1GB to each device.

We have 1 SCCM server VM. We want to do 50 PC's at once. - We cant even get 2-3 done without saturating the bandwidth. - What can we do to improve this. - I can add another NIC to SCCM server - but how will this help. (without ether-channel on switches)  Is there a way to manage better performcance bandwidth to do bulk imaging in sccm.?

thanks

Sorry a bit confused - It may be at unicast (will check). - Are you saying multicast will significantly improve performance? - with the unicast set - it still sends to multi as i understand - as long as the IPs have not changed since the inventory /collection.

multicast will send the same packet to multiple recipients at once. This way there is only one packet going to multiple destinations at the same time.

let say there is 3 packets and 3 destinations
packet 1 dest 1
packet 1 dest 2
packet 1 dest 3
vs packet 1 -> dest1 / dest2 /dest 3
packet 2 -> dest1 /dest 2 /dest 3
packet 3 -> dest1 /dest 2 /dest 3

1/3 the number of packets over the network in this scenario
