Link Aggregation and LACP

Hi there

I have a requirement to provide failover to our customer boxes in case of interface / switch failure, I have been looking at Solaris Link Aggregation with LACP and I wanted to ask a question

Ive seen multiple websites that say the following

Quote:

You cannot use link aggregation if you are using two separate switches. As per IEEE 802.3ad, an aggregation connects two end-points. Some switch vendors implement their own extensions which allows a single "logical" aggregation to span multiple switches, but these solutions are not yet common and don't always explicitly
support 802.3ad.

Does this also mean that if the switches are trunked together that you still cant use 2 switches ??. One absolute requirement of this project is that I use 2 seperate switches, so if this isnt possible, then Ill have to look into IPMP or something else

Any help would be greatly appreciated
Gary
