Abstract: A method for expanding in a balanced manner storage capacity in a cloud without disruption of services provided by the cloud to users includes setting a capacity expansion target of a storage pool of memory devices according to disk space occupation of service currently provided by the storage system when an additional storage node is added to the storage pool of the storage system, expanding the capacity of the storage pool according to the capacity expansion target and adjusting capacity expansion parameter of the storage pool in different periods of time. An electronic device and a non-volatile storage medium performing the above-described method are also disclosed.

Abstract: A virtual desktop system includes a thin client, a virtual desktop managing device, a domain managing device, and a virtualization server. The virtualization server includes at least one virtual machine and virtual desktop. The thin client receives input from a user, and communicates with the virtual desktop managing device by network. The virtual desktop managing device communicates with the domain managing device and virtualization server by network. The domain managing device verifies a domain account of the user according to the inputted information and returns a verification or non-verification to the virtual desktop managing device. The virtual desktop managing device obtains an internet protocol (IP) address of the virtual machine from the virtualization server and returns such IP address to the thin client to enable log-in. A virtual desktop control method is also provided.
