HP IA-32 Server Long Distance Cluster Interconnect for Windows Phase 1: Up to 500m
Source: Hewlett-Packard (HP)
The goals for the Long Distance Cluster Interconnect project are to investigate, select and evaluate technologies that are appropriate to extend distances for the Microsoft cluster interconnect within the Windows 2000 operating environment. Cluster interconnect in this paper applies to the dedicated private network in the Microsoft Cluster Server (MSCS) cluster also known as heartbeat link. This paper documents the first phase of extending heartbeat link distances. Stretching the dedicated private network is one component to achieving resilience in the event of a disaster. The other necessary component is stretching the storage component. HP has accomplished this by multiplexing the IP traffic over the same long haul interconnect that the storage traffic uses.
