Abstract: A method of operation of a storage controller system includes: accessing a first controller having a synchronization bus; accessing a second controller, by the first controller, through the synchronization bus; and receiving a first transaction layer packet by the first controller including performing a multi-cast transmission between the first controller and the second controller through the synchronization bus.

Abstract: System, apparatus, arid method for automatically detecting power-down, disconnection, or other failure of a SCSI bus connected device and isolating the SCSI node from the rest of the computer environment. Sensing a problem at the device node and substituting a buss termination circuit for the termination that had been provided by the device. Sensing the reconnection or power-up of a device at a SCSI bus mode and simultaneously reconnects the device's own terminator and removes the termination provided at disconnection. Particularly useful in clustered computer environments, such as for example, for data base server systems in which a plurality of server computers share a common data base comprised of one or more disk drives on a SCSI bus. Permits any of the servers to be disconnected from the clusters system or network and be repaired or replaced without powering-down or otherwise disabling the entire system or other devices on the system.
