Adding another Cluster into existing CSS LB

Question

Hi,
Im in the process of adding a new cluster into the existing LB. I understand the concept of configuring a new LB but adding a new network to it is a question.
I have preconfigured the LB with a new service called SPWeb 1-4 and an assign this to the content owner Central_Platform using VLAN 144 and 145.
I have one physical connection to the PIX and all port on the PIX is taken. Do I have to setup another physical connection for the new server SPWeb to the PIX?
Both owners Servcorp and Central_Platform are using separate public IP Subnets.
Also, please advise if I miss anything and if you have any suggestions.
Thansks

Answer 1

It would help if you could attach a picture of the network. I really can't understand why you have 2 VLANs on the same network ? Or am I missing the ide ?
Generally I would just do VLAN tag towards the PIX and have several networks that way. If speed isn't a issue I see no problems with that.
