    摘要: Disclosed are methods and apparatus for data tapping within a storage area network (SAN) and providing tapped data to a third party device, such as an appliance. In general, mechanisms are provided in a SAN to allow a data tap of data flowing between an initiator and a target. In one implementation, a data virtual target (DVT) in created in a network device to intercept data sent by a specific initiator to a specific logical unit of a specific target. The data or a copy of the data is sent to both the specific logical unit of the specific target and to an appliance. The data routing may be accomplished by use of a virtual initiator (VI), which is configured to send the data (or a copy of the data) to the specific target and the appliance. In a transparent mode of operations, the DVT has a same PWWN (port world wide name) and FCID (fibre channel identifier) as the specific target. In a first proxy mode of operation, the DVT has a different PWWN and FCID than the specific target. In a second proxy mode of operation, the DVT has a same PWWN and different FCID than the specific target.

    摘要: Disclosed is apparatus and methods for enabling an appliance to receive data being sent between any host of a host cluster to a specified storage device's logical unit (LUN) in a single stream or session. In one embodiment, a data virtual target is initially set up for a specified storage device LUN so that data written from a host to the specified storage device LUN is received by the DVT. An appliance then sends a session request to mirror data that is sent to the DVT (and specified storage device LUN) to a specified LUN of the appliance. The session request is not host specific. That is, data that is sent by any host to the DVT is mirrored to the same appliance LUN.

    摘要: Methods and apparatus for processing a reserve request requesting a reservation of at least a portion of a volume in a system implementing network-based virtualization of storage are disclosed. More particularly, multiple ports and/or network devices together implement the virtualization of storage. When a network device or port receives a reserve request from a host requesting that at least a portion of a volume be reserved, a notification is sent indicating the at least a portion of the volume being reserved. The notification may be sent to one or more network devices or ports. A lock corresponding to the reserve request may then be obtained such that a lock of the at least a portion of the volume is acquired. When another network device or port receives a reserve intention notification, the network device or port stores information indicating that a lock of the at least a portion of the volume has been obtained. Using this information, network devices and/or ports may appropriately handle subsequent reserve requests.
