The switches are most likely Cisco kit so I guess it would be a Cisco 3560G-24TS-24 GbE switch which is a relatively new model with current IOS. A quick google shows they support LACP/IEEE 802.3ad so that looks good. The server brand is unkown to me (if that matters) but obviously it needs to have 2x GbE LAN ports. OS is CentOS 4.1. At the end of the day if Link Aggregation is the way to go, we will make the design use it. It's all IPv4 by the way, no IPv6 support required. Regards, Patrick
