US 10,705,876 B2 · Operation management system and operation management method

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.

Dependent claims

An operation management system for providing a function of storage to a tenant and adjusting the provided function of the storage, comprising:

a node that provides a 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 a physical capacity allocated to the tenant;
and
a capacity allocation and recovery system that 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, wherein the node transmits the size of the logical volume and the size of the written data to the capacity allocation and recovery system, and wherein the capacity allocation and recovery system receives the size of the logical volume and the size of the written data from the node and stores the size of the logical volume and the size of the written data.

An operation management method for adjusting a function included in storage and provided by a capacity allocation and recovery system and a node that provides the function of the storage to a tenant,

wherein the node provides a 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 a physical capacity allocated to the tenant, and
wherein 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, wherein the node transmits the size of the logical volume and the size of the written data to the capacity allocation and recovery system, and wherein the capacity allocation and recovery system receives the size of the logical volume and the size of the written data from the node and stores the size of the logical volume and the size of the written data.
