  • Publication number: 20120311120
    Abstract: In a multi-tenant information processing system, when initially constructing a tenant, design items depending on the tenant are specified for each device constituting the tenant, and design values of the design items are calculated without overlapping with those of other tenants. In a tenant design item management table, the design items set for the devices and information indicating whether the design items depend on the tenant, are stored for each device. In a design algorithm management table, calculation formulae for making the design values to be different for each tenant are stored corresponding to the design items. A tenant design unit refers to the tenant design item management table, specifies the design items depending on the tenant among those corresponding to the devices constituting the tenant, calculates the design values of the design items according to the calculation formula, when initially constructing the tenant.

  • Patent number: 7890669
    Abstract: Provided is a computer system in which an I/O card is shared among physical servers and logical servers. Servers are set in advance such that one I/O card is used exclusively by one physical or logical server, or shared among a plurality of servers. An I/O hub allocates a virtual MM I/O address unique to each physical or logical server to a physical MM I/O address associated with each I/O card. The I/O hub keeps allocation information indicating the relation between the allocated virtual MM I/O address, the physical MM I/O address, and a server identifier unique to each physical or logical server. When a request to access an I/O card is sent from a physical or logical server, the allocation information is referred to and a server identifier is extracted from the access request. The extracted server identifier is used to identify the physical or logical server that has made the access request.
