A computer system assembly has a computer system and an external management device, as well as use of a storage unit in a computer system. Included in the computer system, is an energy supply device; as well as a management unit, which controls and/or manages system parameters based upon system parameter data; and, at least one separate interface for connecting an external management device (smartphone, tablet PC or a notebook, for example). The computer system also has at least one storage unit, which is connected to a management unit for the internal exchange of system parameter data. The at least one storage unit is connected to the at least one separate interface for the external exchange of system parameter data and is operable externally by the separate interface(s) independent from the energy supply device.

Devices and techniques are disclosed wherein an end user can remotely trigger direct data management activities of a data storage device (DSD), such as creating a data snapshot, resetting a snapshot, and setting permissions at the DSD via a remote mobile device app interface.

A system includes a cache and a cache-management component. The cache includes a plurality of cache lines that correspond to a plurality of device endpoints. The cache-management component is configured to receive a transfer request block (TRB) for data transfer involving a device endpoint. In response to a determination that the cache both (i) does not include a cache line assigned to the device endpoint and (ii) does not include an empty cache line, the cache-management component assigns, to the device endpoint, a last cache line that includes a most recently received TRB in the cache, and stores the received TRB to the last cache line.
