Abstract: A method and apparatus for recovering the failed disk of a virtual machine in a virtualization system are disclosed. The apparatus includes a system performance analysis unit, a failed disk recovery unit, and a disk exchange unit. The system performance analysis unit calculates recovery resources, that is, network and disk I/O bandwidths, to be assigned to the recovery of a failed disk by analyzing the performance of the virtualization system. The failed disk recovery unit performs the discovery of the failed disk by recovering a copy disk, that is, a copy of the failed disk, using a mandatory disk stored in the virtualization system while ensuring the performance of virtual machines based on the recovery resources. The disk exchange unit deletes the failed disk and assigns the recovered copy disk to a virtual machine corresponding to the failed disk.
Abstract translation: 公开了一种在虚拟化系统中恢复虚拟机的故障磁盘的方法和装置。 该装置包括系统性能分析单元，故障盘恢复单元和盘交换单元。 系统性能分析单元通过分析虚拟化系统的性能来计算恢复资源，即网络和磁盘I / O带宽，以分配给故障磁盘的恢复。 故障磁盘恢复单元通过使用存储在虚拟化系统中的必需磁盘来恢复复制磁盘（即，故障磁盘的副本）来执行故障磁盘的发现，同时确保基于恢复资源的虚拟机的性能。 磁盘交换单元删除故障磁盘，并将恢复的复制磁盘分配给与故障磁盘对应的虚拟机。

Abstract: An apparatus and method for processing sensitive data. The apparatus includes one or more processors and executable memory for storing at least one program executed by the one or more processors. The at least one program is configured to, in an unprotected data area, read sensitive data from a storage device and transmit the same to a protected data area using the sensitive-data storage endpoint of the protected data area; to, in the protected data area, process the sensitive data using at least one endpoint when a command for a sensitive-data service requested by a client device is received from the unprotected data area; and to, in the unprotected data area, transmit the result of processing the sensitive data to the client device.
