Abstract: A storage switch in accordance with an embodiment of the invention is a highly scalable switch that allows the creation of a SAN that is easy to deploy and that can be centrally managed. Moreover, such a storage switch also allows the deployment of a global infrastructure, allowing the resources of the SAN, such as storage devices, to essentially be positioned anywhere on the globe. Further, such a storage switch allows a multi-protocol SAN, e.g., one that includes both iSCSI or Fibre Channel, and processes data packets at “wire speed.” To further enable wire-speed processing, a switch in accordance with the invention has “intelligence” distributed to each of its linecards, through which it classifies packets into data and control packets, it performs virtualization functions, and it performs protocol translation functions. A switch in accordance with the invention further performs serverless storage services such as mirroring, snapshot, and replication.

Abstract: A data storage system is coupled to a host computer system for the transfer of data between the host and a plurality of data storage devices. The data storage devices are coupled to a plurality of data transfer channels with each data storage channel be coupled to at least a respective one of the data storage devices. Each data transfer channel includes a data buffer and an autonomously operating controller for transferring between the channels data buffer and data storage device. A non-volatile random access storage memory is provided to store cached pages of data. An interface couples the data storage system to the host and through which data is transferred. A reconfigurable data path permits selective data transfer couplings between the data transfers channels, the non-volatile memory, and the interface. A controller directs the configuration of the data path and controls a direct memory access controller for burst transferring data between the interface and the channel data buffers, between the interface and the non-volatile memory and between the non-volatile memory and the channel data buffers.

Abstract: A single instance of a device driver is used to control multiple peripheral devices in a computer system having a central processor for executing an operating system, a memory, and first and second interface buses permitting interconnection of peripheral adapters with the central processor. The interface buses each correspond to different classes of peripheral adapters. The device driver includes an initialization routine for scanning the interface buses to identify predetermined functionally related peripheral adapters. A communications path is provided between the operating system and each of the peripheral adapters of a form appropriate for the particular interface bus connected to each adapter. A control path is also provided between each of the peripheral adapters and the operating system of a form appropriate for the particular interface bus connected to each adapter. The device driver provides for the common control and management of the communications and control paths between the operating system and each of the peripheral adapters.
