  • Patent number: 10705876
    Abstract: An SDS node adjusts a physical capacity included in a logical volume provided to a tenant and is to be allocated to the tenant, based on the size of data written from the tenant. An operation management system provides storage to the tenant and adjusts the provided storage to include a node and a capacity allocation and recovery system. The node provides the logical volume of the storage to the tenant, receives writing of data to the logical volume from the tenant, and writes the received data to a region included in the storage and having the physical capacity allocated to the tenant. The capacity allocation and recovery system determines a physical capacity to be interchanged based on the size of the logical volume, the size of the written data, and the physical capacity allocated to the tenant, and notifies information on the determined physical capacity to the node.

  • Publication number: 20200076681
    Abstract: In an SDS-PaaS management server, a configuration information collector includes a configuration information collector, a configuration manager, an allocation manager, and a performance predictor. The configuration information collector collects system configuration information about a past processing system using a past volume and performance information about a past volume in the past processing system. The configuration manager acquires system configuration information about a new processing system using a new volume. The allocation manager determines a past processing system similar to a system configuration of a new processing system based on the system configuration information about the past processing system. The performance predictor predicts load information about a new volume based on performance information about a past volume used by a past processing system determined to be similar.

  • Patent number: 8279878
    Abstract: A first computer stores a correspondence between a virtual channel and a physical channel (s) in physical channel information and transmits the correspondence between the virtual channel and the physical channel (s) to a second computer having a virtual network interface to which a data transmission instruction is addressed. Upon receiving the correspondence between the virtual channel and the physical channel(s), the second computer stores the received correspondence in the physical channel information. The first computer transmits data in accordance with the data transmission instruction, using one or more physical channels associated with the virtual channel, based on the correspondence stored.

  • Patent number: 8046521
    Abstract: A hypervisor prepares a guest region identifier (RID)-physical region identifier (RID) mapping table for dynamically registering and managing items and performs RID conversion using the guest RID-physical RID mapping table. When the mapping table is used, since it is unnecessary to provide a specific information area representing logical partitions (LPARs) corresponding to respective guests in an RID to be converted, there is no limitation concerning the number of LPARs and a problem in operation can be eliminated.
