  • Publication number: 20060064689
    Abstract: One or more derived timers based on a source timer are provided to accommodate a plurality of periodic tasks while maintaining the high resolution of the source timer. To accommodate a number of periodic tasks, a number of derived timers can be selected utilizing a novel method based on the number of periodic tasks that are most time-critical, the number of tasks that are less time-critical, and the number of tasks that can be performed during the source timer interval. The interval and start time for each derived timer is selected based the source timer and number of the derived timer. After establishing the derived timers, the most time-critical tasks can be assigned to the source timer and the less time-critical tasks arranged amongst the derived timers.

  • Publication number: 20060047850
    Abstract: Systems and methods in accordance with various disclosed embodiments are provided for multi-chassis, multi-pathing solutions in storage area networks. A physical target connected to a first storage switch can be virtualized as a member of a virtual logical unit at a second storage switch to which the physical target is not connected. An inter-chassis link can be provided between the storage switches. If the first storage switch becomes inaccessible, the physical target can be accessed via the second storage switch. A virtual logical unit can also be provisioned at the first switch with a member corresponding to the same physical target. The virtual logical units provisioned at each storage switch can be assigned the same identifier to create a clustered virtual logical unit apparent to host devices. Multiple paths to the same logical unit are thus provided to host devices via either switch.

  • Publication number: 20060036648
    Abstract: Systems and methods in accordance with various disclosed embodiments can manage a mirrored virtual target to synchronize the members of the virtual target and/or to verify that the members of the virtual target are synchronized. In one embodiment, a mirrored virtual target is synchronized by first provisioning at least one first internal virtual logical unit (IVLU) corresponding to at least one destination target of the mirrored target and a second IVLU corresponding to a source target of the mirrored target. A write command is first issued, via one or more internal virtual logical units, to each of the destination target members of the mirrored target. When each destination target is available to receive data, as evidenced by a returned transfer ready signal, a read command is provided to the source target via the second internal virtual logical unit. In this manner, a data path between the source and destination targets is established prior to reading data from the source target.
