Small Tree Communications has released IEEE 802.3ad Link Aggregation networking software for the Apple Xserve and Power Mac computers. 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,” according to Small Tree President Corky Seeber. Pricing starts at US$299 for a two-port, one-group solution.
