Currently, ACE 4710 Appliance has 4 10/100/1000 Ethernet network ports. In my new network project design, ACE is required to be in at least 5 networks (5 Vlans). What is the best way to configure the ACE appliance? Can I configure each phycial port as a trunk and assign multiple VLANs allowed on each trunk? Or should I consider using ACE module instead? Thank you in advance.

that is correct - you don't need a dedicated phyiscal cable for the FT link.
I also just uploaded a ACE_HA configuration documet.

Take a look at figure 1 - vlan 999 is the FT vlan.

The recommended approach is to create a port channel and Q trunk the 4 physical ports together.
take a look at the following URL.
Physical Topology
• It allows the creation of a single very high-bandwidth logical link, helping ensure the highest level (4 Gbps) of throughput possible on the Cisco ACE 4710 appliance.
• It gracefully handles asymmetric traffic profiles typical of web architectures.
• It simplifies the interface configuration since the single PortChannel and IEEE 802.1q trunk need only be configured once and applied to each physical interface.
• Future upgrades, for example from 1 Gbps to 4 Gbps, can be accomplished in real time by installing a license for increased throughput without the need to physically recable the appliance interfaces.
• Individual Cisco ACE contexts are not limited by the throughput of a single 1-Gbps interface. Traffic can be shaped according to the available throughput at the context, virtual-IP, or real-server level rather than at the interface level.
• It allows the Cisco ACE to reach throughput license limits, including throughput limits additionally reserved for management traffic. By default, the entry-level Cisco ACE appliance has a 1-Gbps through-traffic bandwidth limit and an additional 1-Gbps management-traffic bandwidth limit, resulting in a maximum bandwidth of 2 Gbps. Similarly, with the 2-Gbps license, the Cisco ACE has a 2-Gbps through-traffic bandwidth limit
and a 1-Gbps management-traffic bandwidth limit, for a total maximum bandwidth of 3 Gbps.
• The PortChannel provides redundancy should any of the four physical interfaces fail.
• The single logical link can support all the common deployment modes, including routed, bridged, one-arm, and asymmetric server return, while also addressing high availability and stateful connection replication without problems.

Unfortunately, the ACE 4710 Appliance will not be connecting to 6509 in this design. It will be placed behind a pair of firewall & failover, in which connect to 3750G-48TS. Can I still create port channel and trunk 4 physical ports together?

sure the 6500 is just used in the documation to show a "typical" DC switch that ACE4710 could connect into. The switch could be anything.

According to the ACE 4710 data sheet, ACE 4710 appliance can support up to 1024 VLANs, I can create management VLAN and Fault Tolerance/High Availability (FT/HA) VLAN and allow these VLANs in the trunk, correct? I don't need to have a dedicated physical network connection for FT/HA, correct?

Hello,
If I need to pass multiple vlans through the trunk, then is it correct that the directly connected switch should be L3 and not L2.
For e.g. if the topology were ASA -> 2960 -> ACE 4710, I would not be able to pass multiple vlans onto ACE due to L2 switch on single ASA interface/subnet.
Thanks.
