    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 are disclosed for distributing entries among lookup units and selectively enabling less than all of the lookup units when performing a lookup operation. Each of the lookup units is assigned a subset of the possible values of the entries and is programmed with the corresponding entries. In performing a lookup operation on a lookup word, only the lookup units possibly containing a matching entry are enabled which saves power and dissipates less heat. A lookup operation is then performed in the enabled lookup units to generate the lookup result. A lookup unit may correspond to an associative memory device, an associative memory bank, sets of entries within one or more associative memory devices or banks, a lookup control and a memory device, and/or any other lookup mechanism. In one implementation, the partitioning of elements is based on a Patricia tree representation of the possible entries.

    摘要: Zone information is automatically and dynamically configured and managed in a fibre channel storage area network upon detection of network events. Some examples of events that trigger automatic dynamic zone updates include virtual port creation, intrusion/anomaly detection, arbitration decision completion, misconfiguration detection, and device malfunction. The newly created/updated zones are propagated through the fibre channel fabric and provide access control.

    摘要: A technique is provided for facilitating information management in a storage area network. The storage area network may utilize a fibre channel fabric which includes a plurality of ports. The storage area network may also comprise a first volume which includes a first mirror copy and a second mirror copy. The storage area network may further comprise a mirror consistency data structure adapted to store mirror consistency information. A mirror consistency check procedure is performed to determine whether data of the first mirror copy is consistent with data of the second mirror copy. According to one implementation, the mirror consistency check procedure may be implemented using the consistency information stored at the mirror consistency data structure.

    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: Techniques and a network appliance apparatus are provided herein to extend local area networks (LANs) and storage area networks (SANs) beyond a data center while converging the associated local area network and storage area network host layers. A service flow is received at a device in a network. It is determined if the service flow is associated with storage area network or with local area network traffic. In response to determining that the service flow is storage area network traffic, storage area network extension services are performed with respect to the service flow in order to extend the storage area network on behalf of a remote location. In response to determining that the service flow is local area network traffic, local area network extension services are performed with respect to the service flow in order to extend the local area network on behalf of the remote location.

    摘要: Disclosed is a session modification mechanism for altering a data tapping process in a storage area network (SAN). In general, a data tapping mechanism is set up so that an appliance receives SAN data that is tapped from a particular SAN session. That is, the data tapping mechanism provides to a particular appliance a copy of the SAN data that is being written from a particular host to a particular storage device. The session modification mechanism allows the appliance to alter various aspects of the SAN session that is to be (or is being) tapped. Examples of various modification features includes (i) redirecting READ commands initiated by the host to the appliance and not sending such command to the storage device, (ii) redirecting both READ and WRITE commands initiated by the host to the appliance and not sending such commands to the storage device, (iii) halting redirection and thereby causing READ commands initiated by the host to be sent to the storage device and WRITE commands initiated by the host to be mirrored to both the storage device and appliance, (iv) quiescing and unquiescing all data I/O's for the particular storage device and appliance, and (v) stopping and starting the data tapping mechanism.
