Abstract: Described herein are systems, methods, and software to manage multiple sellers of record in a cloud computing environment. In one example, a cloud management service can monitor resource usage in association one or more cloud service providers for each seller of record of a plurality of sellers of record for a customer organization. The cloud management service can further identify interface requirements for reporting the usage information to each of the sellers of record and can communicate the corresponding usage information to each of the sellers of record.

Abstract: The disclosure relates in some aspects to a design for a data storage apparatus with a non-volatile memory that includes a block of memory comprising N wordlines partitioned into a first sub-block comprising a first subset of the N wordlines and a second sub-block comprising a second subset of the N wordlines different than the first subset. In some aspects, the disclosure relates to detecting a failure in a first sub-block. The second sub-block is then marked, in response to a failure detection in the first sub-block, with an initial designation as an unusable sub-block, and a test of the second sub-block is performed to determine a usability of the second sub-block. Based on the test, the second sub-block is then marked with a second designation that is one of a tested usable sub-block or a tested unusable sub-block.

Abstract: The disclosure relates in some aspects to a read scrub design for a non-volatile memory that includes a block comprising N wordlines partitioned into a first sub-block comprising a first subset of the N wordlines and a second sub-block comprising a second subset of the N wordlines different than the first subset. In some aspects, the disclosure relates to detecting a trigger event associated with a read command performed on the first sub-block. A target sub-block test is then performed in response to a detection of the trigger event to determine whether to add the first sub-block to a read scrub queue. If the first sub-block is added to the read scrub queue, a sister sub-block test is then performed to determine whether to add the second sub-block to the read scrub queue.

Abstract: Techniques are provided for maintaining threshold voltages of non-data transistors in a memory device. The memory device has a stack comprising alternating horizontal conductive layers and horizontal dielectric layers. A control circuit is configured to test a threshold voltage criterion of non-data transistors in response to a trigger condition being met with respect to an erase of a data memory cells in a first tier of the stack. The control circuit is configured move valid data out of a data memory cells in a second tier of the stack in response to a determination that the threshold voltage criterion is not met. The control circuit is configured to adjust threshold voltages of the non-data transistors after moving the valid data out of the second set of data memory cells such that the threshold voltage criterion is met.

Abstract: A method and apparatus for the efficient dynamic allocation of additional bandwidth in an optical virtual private network (OVPN) are described herein. A software defined network (SDN) controller may receive a request from an end-user of an OVPN for active bandwidth. Then, the SDN controller may determine whether the OVPN requires additional bandwidth to satisfy the request. As of the request, the additional bandwidth may be pre-deployed, but not yet activated for use. In an example, a path computation element (PCE) of the SDN controller may make this determination. Further, the SDN controller, on a condition that additional bandwidth is required, may determine whether additional bandwidth may be activated based on a policy of the end-user. As a result, the SDN controller, on a condition that additional bandwidth may be activated, may transmit an activation message to one or more line cards of the OVPN to activate the additional bandwidth.

Abstract: A method and apparatus for peer-to-peer file sharing is provided. In some embodiments, the method includes receiving a request for a list of neighbor peers, where the request is made by a requesting peer device, and where the requesting peer device has a local internet service provider (ISP). The method may also include employing a server device to rank each neighbor peer in a plurality of neighbor peers based on whether the respective neighbor peer is external to the local ISP, and if the respective neighbor peer is external to the ISP, further based on a cost metric associated with a next ISP hop from the requesting peer device to the respective neighbor peer. The method may also include generating the list of neighbor peers based on the ranking of the neighbor peers, and enabling transmission of the list of neighbor peers to the requesting peer device.

Abstract: A method and system of analyzing a network to identify a network defect allows user selection of traffic subset to be recorded. After recording the selected traffic subset of the network traffic during network operation, the recorded traffic is then replayed at least in part to the network to replicate, and thus assist in identifying, the network defect.
