  • Publication number: 20240134828
    Abstract: Techniques are described for a hierarchical caching mechanism enabling efficient cross-region replications. In some embodiments, replication-related information (e.g., key-value pairs) is stored in a particular layout in a binary tree (B-tree) of a file system for replication processing. A hierarchy of caches storing a first type of information (e.g., crypto keys associated with iNodes) may be arranged to match the particular layout in the B-tree to enable efficient parallel processing of a second type of information (e.g., files, file data, or symbolic links), where the replication-related information in the B-tree is partitioned into multiple key ranges for parallel processing. In some embodiments, the caches in different hierarchies may be shared by different parallel-processing key ranges and replication jobs in a file system.

  • Patent number: 11967994
    Abstract: An optical transceiver includes a built-in optical switch to switch between diverse fiber paths in switches in a datacenter or in switches between two datacenters. The built-in optical switch can be used to switch between racks in a datacenter to increase capacity for any rack that requests it. A controller, which receives a signal from a server computer in one of the racks, can be external to the optical transceiver or within the optical transceiver. In either case, the server computer can be provided with additional bandwidth when needed. For connections between datacenters, the built-in optical switch allows for optical line protection, but without the need for a splitter circuit, which incurs a significant power loss and requires a more expensive transceiver. Consequently, the built-in optical switch within an optical transceiver can be used in a variety of contexts to increase efficiency and reduce overall costs for network devices.

  • Publication number: 20240120837
    Abstract: Circuits and methods for selectable conversion ratio power converters that include low-dropout (LDO) power supplies adapted to select voltage inputs based on the selected conversion ratio while achieving high efficiency. The LDO power supplies limit current through power FETs of power converters, thereby mitigating or eliminating potentially damaging events. In some embodiments, first and second full gate-drive LDOs have “wired-OR” outputs which may power a target circuit such as a pre-driver (and optionally, a level-shifter) coupled to the gate of a power FET. In some embodiments, first and second reduced gate-drive LDOs have “wired-OR” outputs that may power a final driver coupled to the gate of a power FET. Some embodiments have dual full gate-drive LDOs that power a target circuit such as a pre-driver (and optionally, a level-shifter), while dual reduced gate-drive LDOs that power a final driver coupled to the gate of the power FET.

  • Patent number: 11954129
    Abstract: The present invention relates to a system and a method for updating data models. Input data received from a data source and/or prediction data obtained from a data model is reduced based on baseline reference data to obtain a plurality of representative points. The plurality of representative points are clustered to generate a plurality of clusters. An outlier cluster is detected from the plurality of clusters based on a maximum distance of the plurality of clusters from a highest density cluster and/or comparison of quantity and values of the plurality of representative points with predefined rules. Data drift is identified based on changes in densities of the plurality of clusters. The data model is updated using information corresponding to the outlier cluster and the data drift.

  • Publication number: 20240104062
    Abstract: Techniques are described for snapshot key inter-dependency resolution during cross-region replications. Dependency between a first type of replication-related information (e.g., crypto keys associated with a parent directory iNode or a file iNode) and a second type of replication-related information (e.g., files, file data/FMAPs, or symbolic links) during a cross-region replication may be resolved to enable non-blocking delta application in a target file system. In some embodiments, temporary dummy entries for the first type of information may be created in the B-tree of the target file system for the out-of-order download (e.g., the second type being downloaded before the first type) of these two types of information. In some embodiments, a consolidation process may be performed between the dummy entries and the later-arriving first type of information.

  • Publication number: 20240095127
    Abstract: The Fleetwide Adaptive Rate Limiting Gatekeeper Apparatuses, Processes and Systems (“FARLG”) transforms API call permission request, API call result request datastructure/inputs via FARLG components into API call permission response, API call result response outputs. An API call permission request datastructure associated with an API call of an application structured to identify an API and a set of scopes is obtained. A retry-after interval is determined for each scope in the set of scopes, in which existence of a retry-after interval for a scope indicates that the API previously returned a throttled response for the scope. A wait duration associated with the API call is determined as the maximum retry-after interval across retry-after intervals that exist for the set of scopes. An API call permission response datastructure structured to specify the wait duration is provided.

  • Publication number: 20240094937
    Abstract: Techniques are described for enabling concurrent and non-blocking replication object deletion during cross-region replications. In some embodiments, in a target file system, a target replication pipeline as part of a cross-region replication, and a deletion pipeline operate in parallel. The deletion pipeline deletes processed objects reaching the last pipeline stage of the target replication pipeline after each checkpoint in the target replication pipeline. In some embodiments, after a non-recoverable failure during the cross-region replication, the cross-region replication can be restarted from the beginning (i.e., fresh restart) without waiting for its unused objects in the Object Store to be deleted by utilizing a generation number associated with each object to delete the unused objects in a background process while allowing deleting processed objects as normal for the freshly restarted cross-region replication.

  • Patent number: 11936371
    Abstract: Circuits and methods that limit current through power FETs of power converter to reduce damaging current in-rush events, independent of switching frequency, device mismatches, and PVT variations. Embodiments utilize a closed-loop feedback circuit and/or a calibrated compensation circuit to regulate, substantially independent of frequency, the control voltage VGATE applied to a power FET gate. In a reduced gate-drive mode, connecting a feedback or compensation circuit to the gate of an LDO source-follower FET allows the gate voltage to be regulated to control the LDO output voltage to a final inverter coupled to the gate of a power FET so that VGATE is adjusted to provide a reduced gate-drive to the power FET; connecting to the output of the LDO allows the LDO output voltage to the final inverter to be directly regulated to adjust VGATE; connecting to the gate of the power FET allows VGATE to be directly set.

  • Publication number: 20240080028
    Abstract: Techniques are described herein to enhance capability of floating level translators. For example, increased headroom is accomplished by adaptively bypassing the protection elements of the voltage level translator. In an example, a floating level translator can translate an input signal from a low-voltage domain to a high-voltage domain. A bypass circuit is coupled across the protection elements. The bypass circuit selectively engages during low-voltage operation (e.g., thereby providing a lower loss path relative to loss caused by the high-voltage protection elements and thus increasing the headroom swing), and disengages responsive to the high-voltage reference rail of the high-voltage domain exceeding a threshold or otherwise being high enough (e.g., greater than the potential of the low-voltage domain power rail). The bypass circuit can be implemented in a relatively low-complexity manner (e.g., back-to-back high-voltage FETs) without additional signals to control low-voltage capability.
