Embodiment Construction

[0029] Figure 1 is a block diagram of a computer network 10 that includes an embodiment of the present invention. Generally, the computer network 10 includes: a network-attached storage or system 14 (hereinafter referred to as NAS device 14); a host computer 16 with respect to which any block storage in the NAS device 14 is considered remote; a network infrastructure Structure 18 for transferring data between NAS device 14 and host computer 16 .

[0030] NAS device 14 includes storage network interface 22 for sending / receiving communications to / from network infrastructure 18 according to a packet protocol (eg, TCP / IP). As a result, interface 22 is capable of packetizing communications to be sent over network infrastructure 18 and reassembling related packets received from network infrastructure 18 . Also included in NAS device 14 is block storage interface 24, which in the illustrated embodiment takes the form of a block storage controller. Block storage interface 24 manages...

Abstract

The present invention provides the ability to transfer data between a initiating computer system and a target computer system with a block data storage device, where the target computer system is remote relative to the initiating computer system, that is interface independent relative to the type of the block data storage device employed. In one embodiment, a virtual device driver is employed that implements a command set that is interface independent relative to the block data storage device.

Description

technical field [0001] This invention relates to computer data storage, and more particularly to data storage on block storage within a computer network. Background technique [0002] A typical computer system includes: a processor for executing instructions; memory for storing the instructions executed by the processor and the results of the execution of the instructions; input peripherals for allowing the user to interact with the system (e.g., keyboard, mouse, etc.); Output peripherals, which also allow the user to interact with the system (eg, monitor, printer, etc.); storage peripherals (eg, disk drives, tape drives, etc.), which provide data storage in addition to that provided by memory. When a computer system is running, memory typically includes at least two program sections, an operating system program and an application program (such as a spreadsheet program) section. The operating system program provides several functions, including functions related to input an...
