摘要:
Systems and methods for reducing or eliminating use of read transactions by a message consuming device coupled through a shared bus to a message producing device to transfer a message from the producing device to the consuming device. Features and aspects hereof provide for use of only write transactions on the bus issued by the devices to transfer messages directly into the data memory of the consuming device. A memory manager on the producing device may manage allocation and freeing of buffer space within the data memory of the consuming device. The producing device notifies the consuming device when a message transfer is completed.

The present invention is directed to a system and method for eliminating race conditions in RAID controllers while utilizing a high bandwidth internal architecture for data flow. A remote memory controller of the present invention may ensure that an acknowledge signal is sent only after a memory operation has been actually completed. This may provide for remote direct memory access without coherency problems and data corruption problems while a high bandwidth data flow internal architecture is being utilized.

Apparatus, systems and methods for clustering multiple PCI Express hierarchies to enable access of components in different hierarchies. Each PCI Express hierarchy includes a root device as well as a cluster port for coupling each hierarchy to each other hierarchy of a physical cluster through a PCI Express switched fabric. Memory addresses and transaction IDs are re-mapped by the cluster port of each hierarchy to partition the PCI Express space of the system of multiple hierarchies. A first portion of the partitioned space is reserved for access to local components within a hierarchy. A second portion of the space is used to access remote components of other hierarchies from within a different first hierarchy. The address and transaction ID values exchanged in such remote transactions are re-mapped and used by the cluster port of each hierarchy to route exchanges between hierarchies using standard PCIe root devices, endpoint devices, and switches.

The present invention is directed to a host interface bypass on a fabric based array controller. An apparatus of the present invention may include an external electronic device suitable for performing a function, a controller and a fabric connection. The controller includes at least one internal module, the internal module providing a controller function. The fabric connection communicatively connects the external device to the controller, wherein the module of the controller is directly accessible by the external electronic device.

A method and system for performing a policy-based backup and recovery operation in a storage network is disclosed. In one embodiment, a method of performing a backup and restore operation in a storage network includes detecting each application entity in the storage network and configuring a backup and restore policy associated with the storage network for said each application entity. The storage network includes at least one host server and at least one storage array. The method also includes performing a backup operation of data associated with said each application entity based on the backup and restore policy using application utilities and operating system (OS) utilities configured to interface with said each application entity and a corresponding operating system of the at least one host server respectively, and using a storage array interface configured to directly interface with the at least one storage array.

Systems and methods for handling I/O requests from a host system to a storage system. A system includes an I/O module for processing I/O requests from a host system, a virtualized storage element, and a communication medium coupling the I/O module to the virtualized storage elements. The virtualized storage element includes a mapping table for translating virtual storage locations into physical storage locations and a plurality of physical storage locations. The virtualized storage element generates base virtual addresses using the mapping table to communicate the base virtual addresses to the I/O module. The I/O module generates specific virtual addresses using the base virtual addresses and using information derived from the I/O requests. The I/O module uses the specific virtual addresses in communication with the virtualized storage element to identify the physical storage locations in the virtualized storage element.

System and methods for managing requests of a host system to physical storage partitions. A storage system includes a plurality of storage elements with each storage element configured for providing data storage. A communications switch is communicatively connected to the storage elements for transferring requests to the physical storage partitions. A host system includes a storage router for mapping a portion of the physical storage partitions to logical storage partitions such that the host system can directly access the portion via the requests. Each of the storage elements includes a storage controller configured for processing the requests of the host system. The storage elements also include any of a disk storage device, tape storage device, CD storage device, and a computer memory storage device.
