This Adaptec SCSI Clustering Kit provides all of the hardware components necessary to cluster two servers together (separate clustering services software such as Microsoft Cluster Server Software must be purchased separately from software vendor). The Kit includes two Adaptec 29160LP SCSI cards, two 2-meter VHDCI-VHDCI cables with in-line termination, drivers and clustering manual. Clustering enables multiple servers to be connected to the same storage subsystem in a way that removes the server as a single point of failure, thereby providing higher storage availability. When one server goes down, the surviving server takes over - preserving availability to the attached storage.
