A computer system, method and apparatus includes: centrally managing user identification names and passwords that are assigned to users, target names of storage devices, addresses, and logical units; acquiring target names of storage devices and logical unit names from the user identification names and passwords obtaining the addresses of the storage devices from the user identification names, passwords, and target names; and dynamically creating access control information of the logical units for each session in an iSCSI session establishment processing. The system, method and apparatus enable sharing of storage devices so as to enable users to use logical units assigned to the users in any computers in a system using storage devices complying with the iSCSI protocol, connected to networks, such as IP networks, through node devices, such as cache devices and gateway devices.

The system management server 10 makes a request to the virus detection and removal server 30 for virus detection processing on a specified primary volume of the storage system 20. The virus detection and removal server 30 executes virus detection processing on the requested primary volume and the secondary volume that forms the volume pair at the storage system 20. Even during virus detection processing on the storage system 20, it is possible for the centric PCs 40 and 42 to continue write and read processing on the requested primary volume.

A search system that can easily search documents while ensuring the security is provided. A computer system includes one or a plurality of client devices, a search server, and a storage server connected to each other via a communication channel, and conducts search in response to a search request from one client device. The storage server stores a disk image that allows the client device to perform a boot operation via a network, thereby providing data search service to the client device.

The present invention is to provide a remote boot technique for realizing a remote boot easily. A common storage system 100 comprises: when a demand for the remote boot is received from a terminal unit A 200A, means for sending a program for collecting hardware information and software information of the terminal unit, to the demanding terminal unit A 200A; when the hardware information and the software information are received from the demanding terminal unit A 200A, means for creating registry information by using those information; means for sending a program necessary for the boot processing to the demanding terminal unit A 200A according to the registry information; and means for managing a license of the program properly.

A computer 10a stores boot information OA1 and application information AP1 stored on a local disk 16a, the information being respectively stored as an OS1 shared file group in a shared LU1 and as a AP1 shared file group in a shared LUn+1. For personal information (including personal information of boot information or AP information), computer 10a stores the information as a user personal file group in an personal LU1. Computer 10a transmits image outline information, LU information and file information for the sets of information stored in shared LU1, shared LUn+1 and personal LU1 to an disk-image management server 30, where the information is stored in the storage device 31 of the disk-image management server 30.
摘要:
A storage device has a capability of learning access patterns by which a plurality of computers access to the device. The storage device stores a specific access history for each computer and causes a management computer to report a type of file access. This allows the storage device to save information in a cache memory before start of a file access to be executed by the computer.

In a fault monitoring system which monitors software faults in a computer to be monitored, transmits a fault notification to a different computer connected to the computer through a network when a fault occurs, and controls the monitored computer in accordance with a request command from the different computer connected through the network, a first software environment to be monitored and a second software environment for monitoring the first software environment are constructed on the monitored computer.
摘要:
A parallel processing method for use with a graphics processor wherein graphics processing is performed by each of configured command processors efficiently in a distributed manner, with a host CPU remaining unaware of the number of command processors. Each command group of a variable length from a host CPU is distributed from an FIFO queue to a plurality of parallelly arranged command processors for parallel processing through any free one of input FIFO queues corresponding to the command processors. Upon command group distribution, an identical serial number is added as a command group serial number to the commands constituting the same command group. The results of processing of individual graphics commands by the command processors are collected via output FIFO queues, which also correspond to the processors, in the order of the command group serial numbers added to the commands before the processed results are graphically drawn.
摘要:
An elongated toner box extending in a horizontal direction has a cylindrical portion where a toner discharge port is formed. A wrapping member serving as a shutter is rotatably disposed over the cylindrical portion for selectively shutting off the toner discharge port. The wrapping member has a circular shape concentrical with the cylindrical portion. A developing case is provided to which the toner box is detachably installable. The developing case has a wall confronting the toner box, and a toner inlet port is formed at the wall. A toner inlet shutter is slidably movably supported to the partition wall. When the wrapping member opens and closes the toner discharge port, the wrapping member is positioned close to the outer surface of the toner box and does not largely protrude from the toner box. Further, the discharge port shutter and the inlet port shutter are movable in interlocking relation with each other.
