Yeah, copy/paste error. I knew what I wanted but did not proof read. thanks for the catch.

e0e/e0g are NOT on the same ASIC. They should go to switch #1, if possible, different blades on the same switch

e0f/e0h are NOT on the same ASIC. They should go to switch #2, if possible, different blades on the same switch

That is what I described.
re-wording:

a0a should consist of four ports on each controller: e0e, e0f, e0g & e0h

be use to use mode active on the switch (to force LACP)

Thank you for your response. I verified we have the X6599A SFP. Just to clarify what I meant to ask is that can we have two ports go to one pair of Catalyst 6500 switch and 2 ports go to another pair of Catalyst 6500 switch and tie all four ports into one interface group so I have 40GB and also have switch redundancy. If not possible what is the best configuration I can have to have 40GB throughput.

Yeah, keep looking back at the FAS8020 for some reason...only has the four ports.

 

Make sure you have the X6599A (the 10-GIG SFP) and not the X6596(FC SFP).

For each controller:

a0a should consist of 

e0e/e0g which should go to the same switch, if possible, different blades on the same switch and

e0f/e0h which should go to the same switch, if possible, different blades on the same switch

--> if you cannot split across blades, at least split across ASICs on the same blade.

Each 8040/60/80 controller has 4 10GbE ports (e0a-e0d) and 4 UTA2 ports (e0e-e0h).  Ports e0a-e0d, in a cDOT configuration, are used for the private cluster network while ports e0e-e0h are used for data communications.  No extra 10G card is needed at this time.

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

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?

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.
