摘要： The present invention makes coordination of I/O access operations of operating systems independently running in logical partitions. In a data processing system comprising processors, a main memory, I/O slots, and a node controller, wherein the processors, the main memory, and the I/O slots are interconnected via the node controller and divided into a plurality of partitions in which individual operating systems are run simultaneously, the node controller includes a logical partition arbitration unit which stores information as to whether each logical partition is using an I/O slot and controls access from each logical partition to an I/O slot by referring to the information thus stored.

摘要： Arbitration of IO accesses and band control based on the priority of virtual servers is enabled while curbing performance overhead during IO sharing among the virtual servers. A virtual machine system includes a CPU, a memory, a hypervisor that generates plural virtual servers, and an IO controller that controls an IO interface. The IO controller includes: a DMA receiving unit that receives DMA requests from the IO interface; a decoder that decodes received DMA requests and locates the corresponding virtual servers; a DMA monitoring counter that monitors DMA processing status for each of the virtual servers; a threshold register set in advance for each of the virtual servers; and a priority deciding unit that compares the DMA monitoring counter and the value of the threshold register, and based on processing priority obtained as a result of the comparison, decides the priority of processing of the received DMA requests.

摘要： When a subject of access of a transaction from an IO device is not any resource allocated to a logical partition to which the device having issued the transaction belongs, a report as an error is sent to a CPU, while the transaction is finished on the IO bus. To prevent a transaction between IO devices from gaining access to any resource in another logical partition, one access permission bit is provided for each combination of all the IO devices, and the access is permitted only when the bit has a predetermined value. A reset signal is provided by IO slot so that only an IO slot allocated to a specific logical partition can be reset without affecting any other logical partition. A transaction issued from an IO device in one logical partition is prevented from gaining access to a resource in another logical partition, while proper error handling can be performed.

摘要： Disclosed herewith is a composite type computer system that can assure that a PCI tree to be allocated to a computer is configured completely before the computer is powered. The composite type computer system includes a PCI switch that connects plural computers through PCI interfaces; plural PCI devices connected to the PCI switch; a system controller that controls the computers; and a PCI manager that controls allocation of the PCI devices to the computers. The system controller carries out processings in the steps of (a) powering an object computer to start up its OS; (b) acquiring the identifier of a PCI tree allocated by the system controller to the computer and PCI tree management information denoting the status of the PCI tree; (c) retrying the powering or canceling the powering of the computer if the acquired PCI tree management information denotes the status “not initialized”; and (d) carrying out the powering for the computer if the acquired PCI management information denotes the status “initialized”.

摘要： When the entire system is split into plural partitions on chipsets connecting plural processors, IO hubs, and memory controllers, and an OS is operating on each of the partitions, the present invention prevents a failure in a partition from propagating to other partitions. Based on address information or issuer information included in a packet inputted to a chipset, a partition from which the packet was issued is identified, and an identified partition identifier is added to the packet. Based on the added partition identifier, a partition initializing part selectively deletes the packet issued from the partition in which a failure occurred, thereby preventing the influence of the failure in the failure-causing partition from propagating to other partitions.

摘要： A sever includes an SVP 206 which is a control device capable of executing processing independent of a CPU, and an interrupt 314 is periodically applied to the CPU. An SVP device driver 303, being triggered by the interrupt 314, acquires an amount of server resources used, such as CPU operating time and memory capacity, and user information used by using an API provided by an OS, and delivers such information to an SVP 206. The SVP 206 transmits resource information thus delivered to an accounting server via an NIC 211. The accounting server accounts an amount of server resource used on a user basis and bills the users according to the quantity of server resource used. With such arrangement, it is possible to accurately grasp the usage status of server resource regardless of server loading, and further, it is possible to execute accounting of server resources and billing based on such accounting regardless of types of OS or CPU.

SVP 206经由NIC211发送这样传送给计费服务器的资源信息。计费服务器根据用户的用户数量来计算使用的服务器资源量，并根据所使用的服务器资源的数量向用户收费。通过这样的配置，无论服务器负载如何，都能够准确地掌握服务器资源的使用状态，而且，无论OS或CPU的种类如何，都可以基于这样的计费来执行对服务器资源的计费和计费。
