Disclosed herein are an apparatus and method for managing integrated storage. The apparatus includes a data distribution and storage unit for distributing data in order to store the data in integrated storage, including on-premises storage and cloud storage; a storage management unit for connecting to the integrated storage in order to store the data and providing information about storage tiering pertaining to the data; a data manipulation unit for providing the integrated storage as virtual data storage regardless of a location at which the data is actually stored; and a storage connection unit for providing a user with an interface for the created virtual data storage as a single virtual storage unit, wherein the information about storage tiering varies depending on the performance of storage, the time during which the data is used, and the frequency with which the data is accessed.

Apparatus and method for managing integrated storage

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.

An automatic para-virtualization apparatus of an OS kernel is provided. The automatic para-virtualization apparatus includes a kernel profiler that detects profile information from a native OS kernel, and a virtualization unit that automatically generates a para-virtualized OS kernel that operates on a para-virtualization virtual machine monitor by combining the native OS kernel and the profile information.

Apparatus and method for automatic para-virtualization of OS kernel

Disclosed herein are an apparatus and method for virtualizing Input/Output (I/O) devices. The apparatus includes a hardware device control unit, a guest Operating System (OS) unit, a virtual machine monitor unit, and a host OS unit. The hardware device control unit controls the I/O devices of a terminal. The guest OS unit runs a guest OS via a virtual machine. The virtual machine monitor unit includes shared memory and an event channel, stores an instruction and data, and transfers the stored instruction and the data to a host OS. The host OS unit performs the operation of assigning the shared memory to the virtual machine monitor unit, the operation of generating the event channel, and an operation corresponding to the I/O instruction, stores the results of performance of the operations, and performs control so that the results of the performance of the operations are sent to the guest OS unit.

Apparatus and method for virtualizing input/output devices using shared memory in host-based mobile terminal virtualization environment

Provided are a cluster system, which can reduce power consumption by controlling power at a cluster level according to loads, and a power management method of the cluster system. The cluster system includes a plurality of management target nodes for performing an actual task which the cluster system is supposed to perform, a load balancer/switch for distributing a user's request received through an external network into the management target nodes, and a power management master for monitoring a load of an entire system and performing a power management by controlling the load balancer/switch.
