  • Coalescing change notifications in an I/O virtualization system
    Patent number: 8458306
    Abstract: Efficient and effective mechanisms for coalescing change notifications such as Registered State Change Notifications (RSCNs) are provided. Multiple hosts are connected to an I/O director that allows virtualization of I/O resources including Host Bus Adapters (HBAs) for the various hosts. The I/O director is connected to a Fiber Channel switch. When an RSCN is received by the I/O director, the I/O director queries to Fiber Channel fabric to identify the state change and maintains information about the RSCN so that subsequent redundant RSCNs can be discarded. Change notification information is forwarded to the appropriate hosts connected to the I/O director.
