Small Tree Communications today announced the availability of a free 30-day trial version of its IEEE 802.3ad Link Aggregation product for Mac OS X, which was referenced by Apple during the Xserve Deployment session at WWDC last month. Link aggregation “enables enterprise-class network solutions by bonding or trunking multiple Ethernet ports on a single computer into one virtual interface. This virtual interface provides higher bandwidth, higher availability, and more efficient utilization of the physical links than is otherwise possible.”
