It's my understanding that in order to support HSC devices, SI reverse engineered the SDI and STI boards and came up with their own board that will plug into an HSC and support their disks and tapes. That is why DEC took them to court. Other vendors have made protocol converters that plug into DEC's SDI or STI boards in the HSC, so there is no patent infringement. If you buy an SI disk that plugs into a BI bus controller, then that disk can be available cluster wide and no HSC patent infringements will exist. However that disk is available to the cluster, only if the node it is plugged into is up and running (ie. no failover or volume shadowing). It all depends on your needs and goals. Hope this helps. -- ____________________________________________________________________________ Mike Cooling Internet: cooling@csus.edu Manager, Operating Systems & Network Support California State University, Sacramento
