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： 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.
摘要翻译：服务器包括SVP 206，其是能够独立于CPU执行处理的控制装置，并且中断314周期性地应用于CPU。由中断314触发的SVP设备驱动器303获取使用的服务器资源量，例如CPU操作时间和存储器容量，以及使用由OS提供的API使用的用户信息，并将这些信息传送到SVP 206. 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。

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.
