A method and apparatus for transferring data from a host to a node through a fabric connecting the host to the node. A chip architecture is provided in which a protocol engine provides for on ship processing in transferring data such that frequent interrupts from various components within the chip may be processed without intervention from the host processor. Additionally, context managers are provided to transmit and receive data. The protocol engine creates a list of transmit activities, which is traversed by the context managers, which in turn execute the listed activity in a fashion independent from the protocol engine. In receiving data, the context managers provide a mechanism to process frames of data originating from various sources without requiring intervention from the protocol engine. When receiving data, the context managers are able to process frames from different sources, which arrive out of order. Additionally, the context managers also determine when all frames within a sequence have been received.

A reply descriptor for transmission over an I/O message passing medium in response to a corresponding request message, the descriptor comprises at least one indication field that can function as a ‘flag’ to identify its type, and a content field; whereby a reply message is generated only if at least one predefined condition is not met and the content field will, accordingly, comprise information of that reply messages storage location. The content field to comprise data copied from the I/O request message if each predefined condition is met. A method of responding over an I/O message passing medium to a request message comprising the steps of: generating a reply message to the request message only if at least one predefined condition is not met; generating a reply descriptor having at least one indication field and a content field; whereby the content field comprises information of the reply messages storage location if so generated. Also, a program code on a computer readable storage medium comprising: a first program sub-code for generating a reply message to a corresponding I/O request message only if at least one predefined condition is not met. The first program sub-code comprising instructions for generating a reply descriptor having at least one indication field and a content field that comprises information of the reply messages storage location if said reply message is so generated.

A method for back-off retry with priority routing in a single, cohesive SAS expander includes routing a data transfer between an input of a single, cohesive SAS expander and an output of the single, cohesive SAS expander, wherein the single, cohesive expander includes a first SAS expander, and at least one additional SAS expander via at least one inter-expander link (IEL). The routing of data may further include routing a first OPEN request on a direct path through the first SAS expander to a port of a device and routing a second OPEN request on an alternate path from the first SAS expander and through a second SAS expander to the port of the device. The method further includes determining link availability between the second SAS expander and the port of the device, and, upon determination of a failed link or a busy link, re-routing the data transfer from the second SAS expander to the first SAS expander or a third SAS expander, or retrying the data transfer through the second SAS expander.

The present invention provides an apparatus and a method for embedding information from a first configuration data set having data structures into an embedded processing system, wherein embedding the information maintains user-defined variables. Embedding information includes comparing a first identifier from the first configuration data set with a second identifier from a second configuration data set having data structures to determine if the first identifier differs from the second identifier. In response to a determination of the first identifier differing from the second identifier, a decision is made to merge the first configuration data set with the second configuration data set to form a merged configuration data set. Afterwards, the merged configuration data set is written to the embedded processing system, wherein the merged configuration data set includes maintained user-defined variables.

Methods and systems for generating storage related load factor information for load balancing of multiple virtual machines operable in a cluster of multiple physical processors (such as a blade center). Load factor information is generated within a storage system relating to operation of the storage system as a whole and relating to each of multiple storage controllers in the storage system. The information so generated in the storage system is communicated to a load balancing element associated with the multiple virtual machines. The load balancing element then utilizes the storage related load factor information, optionally in combination with other load factor information, to distribute or redistribute the operation of the multiple virtual machines over the plurality of physical processors.

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.

A first SAS expander including at least phys is operably coupled to a first and a second SAS wide port. A second SAS expander including at least two phys is operably coupled to the first and the second SAS wide port. The first and the second SAS wide port each include at least two lanes, one of each at least two lanes designateable as a connection request lane. The connection request lane of each SAS wide port is operably coupled to a different SAS expander.
