  • Patent number: 6874060
    Abstract: A virtual disk subsystem and method for providing a virtual local drive are disclosed. The virtual disk subsystem includes a channel bridge, such as an Advanced Technology Attachment (ATA) bridge, that receives disk commands from a disk controller, as well as a disk emulator in communication with the channel bridge and a network interface. The disk emulator includes control logic that receives disk commands from the disk controller via the channel bridge and, in response, retrieves data from a remote data storage device and forwards the data to the disk controller, such that the disk controller perceives the remote data storage device as a local device. In an exemplary embodiment, the virtual disk subsystem allows a standard operating system (OS) in a data processing system to function as if the data processing system included the emulated drive.

  • Patent number: 6487613
    Abstract: A system and method for indicating the availability of a controller channel are disclosed. A system incorporating teachings of the present disclosure may include a controller operable to manage an array of data storage devices. The devices may include, for example, disk drives with both read and write functionality. Preferably, the controller will have at least one channel, which may have both an internal and an external connector. The system may also include an indicator operable to indicate when a data storage device is attached to an internal connector of a given channel. As such, employing teachings of the present disclosure may allow a user to accurately and expeditiously determine whether a given controller channel is available.

  • Patent number: 6078979
    Abstract: A shared data storage subsystem having a system controller embedded in a backplane of the shared data subsystem. The system controller monitors the TERMPWR signals of SCSI server busses physically coupled to the shared data subsystem to operably couple and isolate a server SCSI bus with the share data subsystem SCSI bus provides. The system can be used to isolate a server from a data storage subsystem without affecting the operation of other servers operably coupled to the data storage subsystem. The servers and shared data subsystem are implemented in a cluster system. The system controller also monitors environmental conditions of the shared data subsystem. The shared data subsystem includes a plurality of data storage devices such as hard disk drives which can be organized in a RAID configuration.
