Abstract: A file server includes a plurality of stream server computers linking data storage to a data network, and at least two controller servers for controlling the stream server computers. The controller servers are programmed so that at a given time one of the controller servers is active in controlling the stream server computers, and another of the controller servers is inactive. The inactive controller server is programmed to respond automatically to a failure of the active controller server by becoming active. For example, each of the controller servers has a respective flag for indicating whether or not the controller server is active. Each controller server is programmed so that, upon booting, it will read the flag of the other stream server, and if the flag of the other controller server indicates that the other controller server is active, then the controller server becomes inactive. Otherwise, the stream server assumes an active or inactive state based on a predetermined arbitration method.

Abstract: A process for controlling the etch of a silicon dioxide layer at a high etch rate and high selectivity with respect to silicon nitride, particularly in a multilayer structure, by maintaining various portions of the etch chamber at elevated temperatures.

Abstract: The present invention relates to a solid herbicidal composition comprising:a) oxyfluorfen herbicide dissolved in at leasti) a surfactant selected from alkoxylated acetylenic diol surfactants;ii) a surfactant selected from polyoxyalkylene alkyl ether surfactants, andiii) an alkoxylated organosilicone based surfactant,iv) a phosphate solvent of low water solubility, the ratio by weight of phosphate solvent to oxyfluorfen being lower than 3 to 1; andb) a water-soluble salt of N-phosphonomethylglycine, and optionallyc) an inorganic carrier,and to a process for the production thereof.
