Abstract: The disclosure is directed to protecting data of a scalable storage system. A scalable storage system includes a plurality of nodes, each of the nodes having directly-attached storage (DAS), such as one or more hard-disk drives and/or solid-state disk drives. The nodes are coupled via an inter-node communication network, and a substantial entirety of the DAS is globally accessible by each of the nodes. The DAS is protected utilizing intra-node protection to keep data stored in the DAS reliable and globally accessible in presence of a failure within one of the nodes. The DAS is further protected utilizing inter-node protection to keep data stored in the DAS reliable and globally accessible if at least one of the nodes fails.

Abstract: A method for storage driven de-duplication of server memory comprises configuring a storage controller, as part of each IO operation, to generate a unique signature for each data page passing through the controller. The method associates the signature with the data page and stores the associated page and signature. The signature is added to a signature queue for signature match analysis with signatures stored in server memory. Signature analysis is limited to read-only pages to speed up analysis of pages more likely to be duplicates. Once a duplicate page is found, a page table is updated to point to the match page and the duplicate page is added to a free list.

Abstract: The present invention relates to a glass envelope for an illuminating device, the glass envelope comprising a gas channel, a pair of electrodes in communication with the gas channel and a glow-discharge lamp as a source of free electrons coupled to the glass envelope to assist the starting of the illuminating device in dark conditions, for example at night. Preferably, the glass envelope has a front and back surface laminated and integrated together to form a unitary body essentially free of any sealing materials.

Abstract: A semiconductor chip module for a semiconductor chip having an exposed front face with a two dimensional array of contacts is disclosed. A connector plate is located proximate the front face of the chip. The connector plate has a plurality of apertures which correspond to and are aligned with the contacts of the semiconductor chip. A plurality of transmission elements are located proximate the connector plate opposite from the semiconductor chip. A plurality of flexible conductors extend through the respective apertures of the connector plate. The flexible conductors are electrically coupled to the contacts of the chip and to the transmission elements.
