ADAPTIVE COMPRESSION WITH PRE-FILTER CHECK FOR COMPRESSIBILITY TO IMPROVE READS ON A DEDUPLICATION FILE SYSTEM
Improving the performance of read operations in a restore path of an inline deduplication system utilizing a DDBOOST interface by providing an adaptive compression component for use with DDBOOST applications. A built-in compression mode transfers read data if there are sufficient CPU resources in the server and client to compress and decompress the read data without destabilizing the system. CPU usage is tracked to generate predicted respective client and server CPU usage. These respective predictions are compared to defined maximum threshold usage values. If the predicted values do not exceed the thresholds, compression is used, otherwise the data is transmitted over the network as non-compressed data. A pre-filter is used to first determine whether or not the data would benefit from the built-in compression mode.

The technology described herein is directed towards an autonomous reconfigurable intelligent surface (of a node) that is capable of detecting the node's surrounding environment and adjusting the redirection of impinging electromagnetic beams based on the detected environment. Real-time control of the reconfigurable intelligent surface is achieved from within the node itself, while the node consumes relatively little power. A LiDAR-based or other sensor coupled to the node provides a three-dimensional map of the environment's current state. Within the node, an AI module works with a controller to determine the phase of each reconfigurable unit-cell that forms the reconfigurable intelligent surface. The phase response of each cell redirects the impinging electromagnetic wave in the desired direction, e.g., to avoid an obstacle. This can significantly reduce coverage problems in the millimeter-wave band and even higher frequencies for beyond 5G and 6G applications.

The described technology is generally directed towards replicating a filesystem namespace from a source system such as a source node cluster to a target system such as a target node cluster. Directory transfer tasks processed at the source are sent to the target build a replica of a hierarchical namespace on a target cluster, in which the namespace contains the directories and files, with the file content temporarily absent. Files transfer tasks processed at the source are sent to the target to write the content into the files, generally after namespace creation is complete. Directory transfer is recursive, as one directory transfer task creates another directory transfer task for each of its child directories, and can be concurrent and sent as bulk transfer requests for efficiency in reducing overall latency overhead. File content transfer can transfer the content of multiple small files in a single transfer task request.

SYSTEMS AND METHODS PROVIDING SEAMLESS ACCESSIBILITY ACROSS PRE-BOOT AND RUNTIME ENVIRONMENTS
An operating system (OS) software service detects an accessibility change event and takes a snapshot of the accessibility settings before sending and receiving memory-mapped input/output (MMIO) commands with an embedded controller (EC) to establish trust using existing security hardening methods. The software service may send an MMIO command that includes the profile as a payload to the EC. The EC extracts the profile payload and saves it to an NVRAM variable before signaling a basic input/output system (BIOS) during early boot of an available accessibility profile. The EC publishes an accessibility profile presence to a BIOS pre-EFI initialization (PEI) layer, which sends a command to the EC to return the response. The BIOS creates a new hand off block (HOB) command indicative of the accessibility profile and passes this to an early Driver Execution Environment (DXE) stage, which reads the HOB data and locates the accessibility layer within a serial peripheral interface (SPI) firmware volume and loads into memory. This extracted profile information is passed onto the accessibility layer, which applies the profile data to user interface (UI) control attributes.
Memory management processes allocate and recycle pages of replication data pointer (RDP) metadata space in shared memory. When the RDP page currently allocated to an IO thread becomes full, that RDP page is released, and a new RDP page is allocated to the IO thread. The released page eventually becomes fragmented and is added to a list of RDP pages that are ranked based on partial fullness. An IO thread that needs a new RDP page is allocated a mostly empty RDP page from the ranked list, if such a page is available. Otherwise, a new completely empty RDP page is allocated to the IO thread. Use of the ranked lists reduces latency associated with allocation of new RDP pages. Contention between IO threads for RDP metadata space is reduced because each IO thread has exclusive rights to the free RDP metadata space in its currently allocated page.

Ransomware activity detection and data protection is implemented by a remote R2 storage array on an asynchronous remote data replication facility, on which data from a primary R1 storage array is replicated to the remote storage array. Write operations on storage volumes in a remote data replication group are collected in a capture cycle on the primary storage array, along with IO pattern metadata describing both read and write operations on the storage volumes. At the end of the capture cycle, the update and metadata is transmitted to the remote storage array. The remote storage array receives the update and metadata and temporarily stores the update prior to applying it to its copy of the storage volumes. Ransomware anomaly detection is implemented using the update and metadata, and if ransomware activity is detected, the data on the remote R2 storage array is protected, and the update is not applied.

A client-side deduplication library receives from a backup application at a client a job request for a file-copy operation involving one or more files managed by a backup server. A server-initiated communication channel is established between the backup server and client-side deduplication library. A callback from the backup application specifying one or more types of status updates that the application wishes to receive is registered. The backup server is directed to start a job for the file-copy operation. A status update on the job is received over the server-initiated communication channel without having to prompt the backup server for the status update. If the status update is of the type that the backup application wishes to receive, the callback is called to notify the backup application of the status update. If not, the callback is not called.
