802.3ad connection from server to 2 switches

I am trying to find a solution for Windows-based server NIC connectivity redundancy using 2 different Cisco switches. The NIC mfg (Intel) states their NICs support dynamic 802.3ad, which allows the creation of a single EtherChanneling group from a server to 2 different switches. I have tried this in a lab environment & it does appear to work but can't find reference from Cisco to say it is supported. Does anyone know the answer to this or alternative Cisco-supported solution? Thanks. TN

Thanks for the reply. Does anyone know if this will be supported in the future? TN

One way you can achieve redundancy is if the switch the servers are connecting to is a modular switch with redundant power supplies and multiple 10/100 blades. (ie, 4000,4500,6000,6500). You can then configure the Intel NIC's to connect to the switch via EtherChannel. NIC #1 of server going to say blade 2 and NIC #2 of server going to blade 3. Not only do you get redundancy this way but you also get 200Mbps server connectivity.
