摘要： At least one first numbered phy of a first SAS expander is grouped with at least one second numbered phy of a second SAS expander physically separate from the first SAS expander into at least one common SAS wide port. An identical SAS address is assigned to the first SAS expander and the second SAS expander for operating the first SAS expander and the second SAS expander to behave and respond as a single, cohesive SAS expander. The first SAS expander is directly connected to the second SAS expander for inter-expander communications.

摘要： A system and method are described for increasing performance of operations implemented in a storage system utilizing fibre channel, such as by enabling full duplex opens when a JBOD/bridge is involved. In an aspect of the present invention, a method of performing a full duplex open in a fibre channel network having an initiator and a bridge may include initiating an open by the initiator with the bridge. The bridge has a primary physical address and an alias physical address. The alias physical address represents a target device communicatively coupled to the bridge, wherein the open is initiated utilizing the primary physical address. The initiator communicates with the target device.

摘要： The invention relates to an improved Fiber Channel data management technique. More specifically, this patent relates to an improved scheme for managing the related data in related frames that form a sequence. This patent also generally relates to the management of multiple, active sequences which are simultaneously in transit on a Fiber Channel. This invention provides a means for efficiently locating the sequence status block associated with an arbitrary Fiber Channel sequence by using the source identifier field, the originator exchange identifier field and/or the sequence identifier fields of a Fiber Channel frame header to construct a hash table lookup search.

摘要： A method of using a frame sequence to transmit a data block from a transmitting device to a receiving device is disclosed. One step of the method includes generating a first frame of the frame sequence that includes a last portion of the data block and a relative offset which indicates a relative displacement between a first portion of the data block and the last portion of the data block. Another step of the method includes generating a second frame of the frame sequence that includes the first portion of the data block. The method also includes the step of transmitting the first frame of the frame sequence from the transmitting device to the receiving device before transmitting the second frame. Yet another step of the method includes receiving the first frame of the frame sequence from the transmitting device before receiving the second frame. Moreover, the method includes allocating a storage area for the data block, the storage area having a storage capacity that is based on the relative offset of the first frame. A network device which allocates storage for a data packet based upon a relative offset for a last portion of the data block is also disclosed.

In an aspect of the present invention, a system for storing electronic data may include a host and a data storage apparatus communicatively coupled to the host. The host has cache coherency functionality. The data storage apparatus includes a first storage controller communicatively coupled to at least one storage device, the first storage controller further coupled to a first cache. A second storage controller is also included, which is communicatively coupled to at least one storage device, the second storage controller further coupled to a second cache. The cache coherency functionality of the host provides coherency of the first cache coupled to the first storage controller with the second cache coupled to the second storage controller.
