摘要： In one embodiment of the present invention, a data-backup method includes partitioning a fingerprint namespace among a cluster of backup servers, the fingerprint namespace comprising fingerprints for representing units of data, each backup server of the cluster of backup servers managing units of data having fingerprints corresponding to an assigned partition of the fingerprint namespace. The method further includes receiving backup information from a client computing device for a block of data comprising units of data, the backup information including at least a fingerprint for each of the units of data and client-specific backup information. In addition, the method includes, utilizing the fingerprint for each of the units of data, deduplicating the units of data in parallel at the cluster of backup servers in accordance with the partitioning step, the deduplicating step comprising identifying ones of the units data already stored by the cluster of backup servers.

摘要： A module for radio frequency signal circuits includes an electrically conductive housing. Coax connectors are secured to the rear face of the housing. A circuit board is contained within the interior spaced between sidewalls of the housing. A ground side of the circuit board includes a layer of electrically conductive material which is electrically connected to the housing. Coax cables extend within the interior of the housing from the coax connectors and between the ground side of the circuit board and an opposing sidewall. An opposite side of the circuit board contains circuit components interconnected with one another through a plurality of circuit paths.
