Hello,

I seek advices and examples of network design with virtualised nodes.

I have a brunch of Dell R710 (4 GigE NICs) and 2 Cisco 4948 switchs.

My plan was, for each server, to connect 2 interfaces on one switch and the two remaining on the other switch, then create a LACP trunk on each switch and activate STP.
Each LACP trunk will have the same vlans enabled.

In this configuration, one of the LACP trunk VLAN port will be disabled by STP and the other will pass traffic, giving me a fully redundant network.

First question: is it a good idea and a good network design ?
I read that STP can cause more problems than it resolves, is that right ? How can I prevent it ?

Second one: Can I "balance traffic" between trunks (aka have different VLANs enabled on both LACP trunks) ?

Thanks
