摘要： Provided is a method of managing a network system including a computer device which processes data, a storage system which is used in the computer device to store data, and a switch which connects the computer device and the storage system to each other. The storage system sets VLANs and the priority of each of the VLANs on the switch, VLANs including at least one of a control VLAN transferring mainly control data, and at least one of a user VLAN transferring data other than the control data. The switch transfers data in a manner that allows the VLANs of higher priority to precede the VLANs of lower priority. Therefore the storage system manages a network in accordance with the level of load or the like of respective VLANs.

摘要： A method of controlling cache allocation to be executed by a server computer is arranged to realize resource management for securing a proper cache size. The server computer is arranged to have a memory unit and a CPU. The memory unit stores a memory allowable size of a memory to be secured as a disk cache by each of the programs to be executed by the server computer. In a case that a new disk cache is allocated to the memory unit when accessing a disk drive under the control of the program being executed, the CPU reads from the memory the memory allowable size corresponding with the program and allocates the disk cache to the memory unit so that the disk cache may stay in the range of the memory allowable size.

摘要： A data transfer method for a computer system in which a computer is logically divided into a plurality of logical processing units and a logical coupling unit. A correspondence between a start of physical addresses of a memory of each logical processing units in a memory of the computer is stored in advance. If a first logical processing unit issues a write command to the logical coupling unit by designating a logical address of data, the logical coupling unit stores an identifier and the logical address of the first logical processing unit. If a second logical processing unit issues a read command of the data, a physical address of data storage corresponding to the logical address of the first logical processing unit is calculated in accordance with the identifier and the logical address of the first logical processing unit and the address correspondence. The data is read by using the calculated physical address.

摘要： Consistency of a shared disk is secured in system switching in a hot standby system. In the standby system in which an active computer and standby computer share the shared disk, when a write I/O request is issued from the active computer, information about a start of the I/O is recorded in, for example, a memory. When the I/O is completed, the information is deleted from the memory. When a failure occurs in the active computer, the active computer transmits the record of the information about the start of the I/O, to the standby computer. The standby computer verifies the record to recover a disk in which the I/O is to be executed.

摘要： A server system has servers that can be operated through switching as a primary system and a standby system, and a shared disk unit for storing data accessed by the servers. Each of the servers has a driver that acquires information on a configuration inside the shared disk unit after starting of the system. The driver sets the shared disk unit in an active state in which an access request can be sent to the shared disk unit. Access control determines whether the access request issued by an application should be sent on the basis of a management table indicating inhibited types of access requests for each access destination. The access control sends the access request to the driver when the access request is not inhibited for an access destination of the access request. By this arrangement, hot standby switching processing can be performed at high speed.

摘要： A parallel computer system and a block transfer method and computer program for use with the parallel computer system which includes at least one processing unit divided into a plurality of logical processing units and a connecting device which exchanges commands and acknowledgements with the processing unit. The connecting device edits into a single command or acknowledgement individual commands or acknowledgements to be sent to the logical processing units and sends the single command or acknowledgement to the processing unit. The single command or acknowledgement includes a header, a command or acknowledgement code, logical processing unit numbers and pieces of command or acknowledge information corresponding to the logical processing units. The processing unit divides the single command or acknowledge into the individual commands or acknowledgements for the logical processing units and notifies the latter of these commands or acknowledgements. The invention operates in a similar manner when sending commands or acknowledgements from the logical processing units to the connecting device.
