Hi,
I Have an App server in my company that is the heart and brain for our business. I wanted to implement load balance between nic’s to make server available to users even if one of the nic’s fail, switch port fail or even switch fails. I was reading some stuff on internet and found that I should use IEEE 802.3ad Dynamic Link Aggregation. On Server I have both integrated Broadcom nic’s and installed their Broadcom Advanced Control Suite (BACS) and configured those two nics to 802.3ad DLA. Both nics were on different switches. Everything worked ok. When I plug out cable from Active nic, other one takes job without interruption. Server was working a OK.
But…
When I ping server every 20th or 50th ping doesn’t come back. Which wasn’t like before “operation”. After month of usage those lost pings were increasing.
And I noticed that nics are not working simultaneously. Which was my wish to speed up receiving and sending packets.
So my question is – Am doing something wrong or when you implement load balancig you just have to lose some packets? And to mention I didn’t change anything on switches (Both Cisco 2960G) which by the way aren’t managed at all.
