The present invention provides a sever which includes a network interface, a processor and a first storage device, wherein the processor is arranged for communicating with an electronic device via the network interface, and the first storage device stores data. In the operations of the server, the processor determines whether the data is cold data; and when the data is determined as the cold data, the processor moves a second portion of the data to a second storage device, and a first portion of the data is remained in the first storage device, wherein the data amount of the first portion is less than data amount of the second portion, and the access speed of the first storage device is higher than the access speed of the second storage device.

Server and associated computer program product using different transmission speed for different portions of cold data

A device and a method for virtual storage are provided. The device includes a physical processor, a hypervisor and a physical storage. The hypervisor is executed on the physical processor and configured to create at least one client virtual machine and a controller virtual machine. The physical storage is clustered with physical storage of at least another device via the controller virtual machine to form a storage cluster. The controller virtual machine is further configured to define a virtual storage pool in the storage cluster and create at least one virtual storage controller virtual machine to interface the at least one client virtual machine with the virtual storage pool so that the at least one client virtual machine accesses the virtual storage pool via the at least one virtual storage controller virtual machine and the controller virtual machine. The method is applied to the device to implement the operations.

Techniques to perform root volume encryption in a para-virtualized virtual machine are described. A disk layout supports the root volume encryption, set key flow, and normal boot flow of the para-virtualized virtual machine. An implementation for performing encryption for a cloud-based service is disclosed.

A secure real-time data replication system includes a key management server that provides keys to hosts that store encrypted data. Data to be written in one host is encrypted using a key received from the key management server; the encrypted data is stored in the host. A copy of the data is provided to another host for real-time data replication. In the other host, the copy of the data is encrypted using another key received from the key management server; the encrypted copy of the data is stored in the other host. Keys are provided by the key management server based on policy rules governing the keys.
