We are looking to buy new FAS8040 and configure it with CDOT. I am looking for network recommendation with Cisco 6509 VSS. 8040 has four 10G ports per controller and I want to use all four ports to create an interface group with two VLAN, using VLAN tagging. I want 2 ports to go to one VSS switch and 2 ports to go to other VSS switch so I have switch redundancy also. I am not sure if it is doable since I am going to two different switches. Any recommendation is appreciated.

A pair of Catalyst 6500 switches configured with VSS appear to be a single switch. So configure all four ports as a Port-Channel, with two on one switch and two on the other.
You should watch that the interswitch links used by VSS do not get overloaded though. You need to allow for up to 20 Gbps across the interconnect, plus whatever else you are running through the switches.

As Tom mentioned, the switches you're using can be configured to allow for LACP pairs across switches. For each head, you want to create two ifgroups with one leg on each switch. From those ifgroups, you should create vlan tagged interfaces, and then define LIFs on those. Each vlan should have its own failover group, and you should associate each LIF with a failover group for the vlan it's part of.
With this setup, if any cable or switch goes down, all your interfaces remain up. If any 8040 controller fails, all the LIFs on that controller will fail over to the other one.

You can also tie the four links into a single interface group and carve it up into multiple VLANs.
What ports are you going to use for the cluster interconnect? I assume you’re ordering a switchless cluster of two nodes?

No that won't work. If you are configuring cDOT, at least two ports per controller are reserved for the cluster network (e0a & e0c) This leaves e0b and e0d available for normal network access
The recommended configuration is to use all four ports for the cluster network (e0a, e0b, e0c & e0d). In this case, if you need/want 10gig network connections you would need an extra 10gig card
AS indicated earlier in this thread, from each controller: a0a should be a multimode_lacp VIF and contain: e0b -> switch 1 e0d -> switch 2
Then you can create your VLANs: a0a-123, a0a-456
Place your LIFs on the tagged VLANs
Create a failover group for node-01:a0a-123 and node-02:a0a-123 Create a failover group for node-01:a0a-456 and node-02:a0a-456
Assign the failover group to the appropriate LIF
PS: DO NOT FORGET to disable spanning tree on the switch ports. --> spanning tree protocol should only be enabled on ports connected to other switches. --> it is not needed on ports connected to en hosts --> in a cluster failover event it could take an extra 45 seconds for a port to become available.(not good) --> remember to use the right version of the command. if it is a trunk, you usually need that on the line
