I'm in process of ordering two ACE appliances.
I have two core switches with layer 3 connectivity to the server farm switches (4506).
I'm suggesting installing the two appliances as layer3 mode. If I understood the layer3 mode well, one port of each ACE appliance will be connected to the core switch (trunk) with the same VLAN as the core and assign interface VLAN from the ACE appliance and the other port of the ACE will be connected to the server farm switches as kayer2 (access servers VLAN).
All the requests destined for virtual server IP will go to the ACE appliance and the ACE appliance will forward them to the real servers.
1-Is this a good suggested design?
2-What is the Layer2 mode?
3-Does the two appliances synchronizes each other in case one packet is forwarded to the first core switch and the second packet is forwarded to the second core switch for the same session?
Thanks in advance
