摘要： A system and computer program product for automatically managing copies of source data volumes are provided. A copy management agent receives a message that target volume copies of source volumes are available. The copy management agent accesses the target volume copies of the source volumes. The copy management agent analyzes metadata for the target volume copies. The copy management agent determines whether any of the target volume copies is a boot volume copy based on the analyzed metadata. In response to a determination that one of the target volume copies is a boot volume copy, the copy management agent directs a provisioning agent to provision a new host for the target volume copies. The copy management agent directs the storage subsystem to present the target volume copies to a storage area network port associated with the new host. Then, the new host is booted using the boot volume copy.

摘要： A method of etching a semiconductor substrate. The method includes the steps of applying a photoresist etch mask layer to a device surface of the substrate. A select first area of the photoresist etch mask is masked, imaged and developed. A select second area of the photoresist etch mask layer is irradiated to assist in post etch stripping of the etch mask layer from the select second area. The substrate is etched to form fluid supply slots through a thickness of the substrate. At least the select second area of the etch mask layer is removed from the substrate, whereby mask layer residue formed from the select second area of the etch mask layer is significantly reduced.

摘要： A method and apparatus for estimating channel characteristics in a multicarrier wireless receiver such as an OFDM wireless receiver. The method includes determining a channel estimate for each of a set of subcarriers by receiving multicarrier data as a result of a wireless transmission of data that includes a known signal, wherein the determining uses a part of the received data that corresponds to the known signal. The method further includes smoothing the channel estimates according to a smoothing filter to form smoothed channel estimates. The smoothed channel estimate for a particular subcarrier includes a contribution from the channel estimates of one or more subcarriers nearby the particular subcarrier take advantage of correlation that may exist between the particular subcarrier's channel and the channels of the one or more nearby subcarriers. In one version, the transmitted data includes at least one additional known signal, and each smoothed channel estimate is a smoothed version of the average of sets of channel estimates. In such a version, each set of channel estimates is determined using a respective part of the received data that corresponds to a corresponding one of the known signals.
