Success Story Dunham-Bush Dunham-Bush, a pioneer and industry leader in rotary screw compressor technology, selects Allied Telesis for a cost-effective and highly available network. The customer Dunham-Bush, a pioneer and industry leader in rotary screw compressor technology, is based in Kajang, Malaysia. The company builds refrigeration systems and air-cooled rotary screw flooded chillers. It also provides customized, leading-edge cooling systems to commercial buildings, schools, hospitals, airports, factories, and residences. Dunham-Bush was formed in the 1950s through the merger of the C.A. Dunham Company (est. 1894) and the Bush Manufacturing Company (est. 1906). With more than 100 years of combined research and development, it produces one of the broadest lines of air-cooled and liquid-cooled chillers in the industry. From their corporate headquarters in Kajang, Dunham-Bush operates a global network of sales and service offices. Dunham-Bush has manufacturing facilities in many countries including the United States, England, Malaysia, and China.

During normal operation with VCStack, all bandwidth and routing power in the network are fully available for use all the time. If a link or device fails, some of the bandwidth or forwarding power is lost, but the network remains fully operational and all remaining resources continue to be fully utilized. The key advantage of VCStack comes from configuring the links from the access switches to the core as an 802.3ad link aggregation.
