Trunking on Server NIC

As Dell and Sun provide PCI-x or PCI-e only, with just 2 build-in NICs, while server admins are quite reluctant to add additional NIC to run in traditional way, like Front-end NIC, Backup NIC, Load-Balancing-NIC, Mgmt NIC cause the PCI-x or PCI-e are quite expensive, not sure you encounter such issue or not, and how would you like deal with such issue and cater server's requirement, because we are quite reluctant to offer 802.1q trunk to server NIC either in our data center where we have hundreds of servers which are sitting behind FWSM(s). thanks.

Best Regards.

Re: Trunking on Server NIC

From a networking perspective, there is not too much difference between trunking and adding additional adapters in hardware.

With more adapters in a server it also becomes more complex to control routing.

A more preferrable method (at least in my opinion) is to assign the servers into relatively small VLANs. These VLANs can be set up for servers belonging to the same customer or (load)sharing the same application.

With smaller vlans you are able to use a single or teamed adapter for all traffic flows and you are still unlikely to run into network-load issues.
