It is an object of the present invention to conduct data transfer or data copying between a plurality of storage systems, without affecting the host computer of the storage systems. An excitation winding, a vice-output winding and an active snubber circuit are connected to a primary side of a flyback-based transformer. The openingclosing means is a fastener. The value of the counter is then hashed to produce an assignment table index. The invention also relates to corresponding devices and computer program products. More specifically, the mercury ionic gas standard generator uses a reservoir being coated with an inert silicon-based coating for transporting a volume of an aqueous ionic mercury solution to a liquid mass flow controller and vaporizer.
