摘要： In a case where a master virtual machine, which is constructed on the basis of master information for configuring either part or all of a virtual machine, and an individual virtual machine, which is constructed on the basis of individual information that is configured partially or entirely in accordance with the master information, exist as the types of virtual machines that a physical client provides to a user terminal, a security check of a plurality of virtual machines is selectively executed, with respect to each check item, for a virtual machine of the type corresponding to the contents of the check item.

摘要： An object is to efficiently solve a quadratic programming problem having a k-hot constraint (k is a positive integer) for binary variables. A preferred aspect of the invention is an optimization method for, using an information processing apparatus, solving a quadratic programming problem in which one or more independent k-hot constraints are imposed on binary variables, the information processing apparatus including a processor, a storage device, an input device, and an output device. The information processing apparatus relaxes the binary variables into continuous values by adding correction values to a nonlinear coefficients of the binary variables on which the k-hot constraints are imposed, and the information processing apparatus executes a solution search while satisfying the k-hot constraints by executing a state transition such that a sum of a set of continuous variables on which the k-hot constraint is imposed is constant.

摘要： In the computer system, a storage system provides a storage level virtual volume based on thin provisioning technology, to a physical server on which a virtual machine is defined. The storage system releases the area of the logical volume corresponding to the storage level virtual volume accessed by a virtual machine which is specified to be deleted, on the basis of storage level virtual volume conversion information which is managed by the storage system.

摘要： To manage a storage system for storing write data of I/O (Input/Output) command to a storage volume, a computer program comprises: code for analyzing performance information of I/O operation for a period of time on a storage volume basis; code for deriving a periodic time window having a same type of I/O performance characteristic; code for determining a type of Service Level Objectives (SLO) on a periodic time window basis; code for calculating a threshold value of the SLO; code for providing a user with a type of SLO for a periodic monitoring window and a threshold value of SLO for the periodic monitoring window on a storage volume group basis; and code for monitoring, on a storage volume basis, whether or not a service level value for the periodic monitoring window violates the SLO based on the threshold value of SLO for the periodic monitoring window.
