Abstract
For accomplishing an interruption-free power supply operation of a system unit (HDD) in a computer system with a plurality of system computers (Sa; Sb) sharing the system unit (HDD) without having the limitation to a local location, a method and an arrangement is [sic] proposed in accord wherewith the operation of the respective station computers (Sa; Sb) respectively ensues with their own interruption-free power supplies (USVa; USVb) and, for the power supply of the shared system unit (HDD), the shared system unit (HDD) is always connected to an active interruption-free power supply (for example, USVb) by an automatically switching switchover (PCS) that monitors the voltage of its inputs.
Claims7
A method for providing an uninterruptible power supply operation of a shared system unit in a computer system with a plurality of station computers using said shared system unit in common, comprising the steps of:
- providing station computers with their own uninterruptible power supplies;
- and
- co-connecting and maintaining said shared system unit to an active uninterruptible power supply which is one of the station computer uninterruptable power supplies by an automatically switching voltage-monitoring unit.
An arrangement for providing an uninterruptible power supply operation in a computer system, said arrangement comprising:
- a system unit;
- a plurality of station computers using said system unit in common;
- a plurality of uninterruptible power supplies, each of which is separately respectively connected to each said station computer;
- and
- a switchover unit having a plurality of input terminals and an output terminal, each of said input terminals being connected to said uninterruptible power supplies, said switchover unit monitoring a voltage at said input terminals, and automatically switching to a voltage-carrying input terminal and thereby connects said voltage-carrying input terminal to said output terminal which is connected to said shared system unit.
