Abstract: Techniques are provided for failing over an aggregate from one file system instance to a different file system instance of a distributed scale-out storage system. The aggregate may be stored within distributed storage that is accessible to a plurality of file system instances of the distributed scale-out storage system. When the aggregate is failed over from a first file system instance to a second file system instance, the first file system instance may still have a valid read lease that allows the first file system instance to serve client I/O, directed to the aggregate, using a cache. In order to prevent the first file system instance from serving stale data from the cache before the read lease expires, state machines and a set of control data are used to ensure that the second file system instance attaches to the aggregate only after the read lease has expired.

Abstract: The invention relates to a data center system, comprising at least the following components: a data center, a power source module comprising a gas-powered electricity generator, and an energy conversion module, wherein the data center is connected to at least two prime-rated electricity sources, wherein a first electricity source is a grid and a second electricity source is the power source module that is connected to a gas network, to the data center and to the grid, wherein the energy conversion module is connected to a regenerative energy source and to the gas network, wherein the energy conversion module generates synthetic gas using electricity from the regenerative energy source, and to feed the generated gas into the gas network, wherein the system is configured to provide electricity from the power source module to the data center, such as to export power to the grid for stabilizing the grid.

Abstract: A method for enabling enable use of multiple active paths for TDM traffic over a packet switched network, comprises: receiving at least two copies of a replicated packet including TDM information via at least two paths through the packet switched network, the at least two copies of the replicated packet including at least a first copy of the replicated packet received via a first of the at least two paths, and a second copy of the replicated packet received via a second of the at least two paths; selecting a copy of the replicated packet from among the at least two copies of the replicated packet; inputting the selected copy of the replicated packet to a jitter buffer; discarding unselected ones of the at least two copies of the replicated packet; and outputting the selected copy of the replicated packet from the jitter buffer to a TDM endpoint device.

Abstract: This disclosure describes systems for cooling one or more data halls of a data center that include one or more sections of a cooling spine. Each section of the cooling spine includes a riser module, a manifold module, and one or more arrays of cooling units. The riser module includes riser piping configured to fluidically couple to a liquid cooling system. The manifold module includes manifold piping fluidically coupled to the riser piping. Each array of cooling units is positioned toward a data hall of the one or more data halls of the data center and includes a heat exchanger assembly and a circulation assembly. The heat exchanger assembly is fluidically coupled to the manifold piping and configured to cool return air from a hot aisle adjacent a row of cabinets. The circulation assembly is configured to discharge supply air to a cold aisle adjacent the row of cabinets.

Abstract: A method and an arrangement for air-conditioning a cold aisle which is partially bounded by heat-generating devices and is arranged in a hot room, the hot room being separated from a second room by a boundary wall, and a region of the boundary wall is formed by a heat exchanger, such that air that is conveyed through the heat exchanger by the fan is supplied to the cold aisle. An opening with a fan is provided in the boundary wall. The cold aisle is connected to the boundary wall so that the opening is surrounded by the cold aisle.

Abstract: A system is disclosed that protects private data of users while permitting the monitoring or tracking of electronic devices that are shared for both business and private purposes. The electronic devices may be configured to selectively encrypt location data, and/or other types of data, before such data is transmitted to a monitoring center. For example, data collected or generated on a user device outside of work hours may be encrypted with a private key of the device's user prior to transmission to the monitoring center, so that the data is not accessible to the employer. Data collected or generated during work hours may be transmitted without such encryption.
