Abstract: A system and method for managing the multipath failover protocol of a storage area network that includes storage systems that include multiple ports and multiple storage controllers. A number of available storage paths between each server and each storage unit of the storage system are identified. A storage path is selected. In the event that the storage path becomes inoperable, an alternate storage path is selected in replacement of the inoperable storage path. The alternate storage path will be selected so that it does not include a storage controller that was part of the inoperable storage path.

Abstract: The system and method is described herein for preventing HBA port logins to a networked target device unless the HBA has been authorized to perform a port login to that networked device. The HBA driver selectively performs a port login with a target device based on whether the unique hardware address of the target device is included on the HBA driver's unique hardware address access table. During the storage assignment step of the login process, the user selects the target devices that will be assigned to the host. The unique hardware addresses of these target devices will be stored on a unique hardware address access list. During the device discovery step of the login process, the HBA driver compares the unique hardware address of the target device with the unique hardware address access list. If the target device's unique hardware address is listed on the unique hardware address access list, then the HBA driver will proceed with a port login with that target device.

Abstract: A system and method for correlating the command queue depth of the servers of a storage area network to the command queue depth of the storage controllers of the computer network are provided. For each storage controller, the servers are identified that have logical ownership of the logical storage units managed by each respective storage controller. For each storage controller, the execution throttle levels for those servers that have logical ownership over logical storage units of the storage controller are verified according to rules governing the command throughput of the servers and the storage controllers.

Abstract: In the present disclosure, a method and system is provided for generating worldwide names. The method and system includes reading a media access control (MAC) address associated with a network interface card (NIC). A fiber channel device associated with the NIC is then identified. A world wide name for the identified fiber channel device is then generated by appending a vendor specific identifier assigned to the fiber channel device to the MAC address obtained from the NIC.
