1.2.2 DWZZH-09

The DWZZH-09 is made up of two large Hubs connected by a 0.5m VHDCI cable (BN 37A-0E). A tri-link attached to the DWZZH-A5 portion of the Hub allows the attachment of a storage device up to 25 meters away from the Hub. The Hub provides radial connectivity by allowing the user to connect up to eight host bus adapters from any number of distributed systems to the DWZZH-09. Termination is provided by each of the host ports. (See Figure 1-2.)
