Abstract: Examples of file analytics systems are described that may obtain metadata data and events data from a virtualized file server. The file analytics systems may detect one or more events from the events data matching a criteria indicating malicious activity. The file analytics systems may validate the detection of malicious activity. The validation may be performed by comparing the file type, such as the MIME type, of sample files before and after the suspected malicious activity. The systems may recover a share of the distributed file server including the one or more affected files by replacing the one or more affected files with stored versions of the one or more affected files from a snapshot of the share taken prior to the detected malicious activity.

Abstract: Examples described herein are generally directed towards file share access, and more specifically towards a mechanism to connect file shares at the protocol level in a distributed file server environment. In operation, a first FSVM hosting a first file share may receive a request by a client to access a location in a name space. The first FSVM may determine the location is at a second file share linked to the first file share. The first FSVM may provide access to the second file share to the client. In some examples, the first file share and the second file share may be linked at the directory level.

Abstract: An example file server manager updates a selected share of a destination distributed file server based on a snapshot of at least a portion of a selected share of a source distributed file server. The selected share of the destination distributed file server is updated while the source distributed file server serves client requests for storage items of the selected share of the source distributed file server. The file server manager receives a request to failover from the source distributed file server to the destination distributed file server and configures the destination distributed file server to service read and write requests for storage items of the selected share of the destination distributed file server. The file server manager further redirects client requests for storage items of the selected share of the source distributed file server to the destination distributed file server by updating active directory information.

Abstract: An elastic request handling technique limits a number of threads used to service input/output (I/O) requests of a low-latency I/O workload received by a file system server executing on a cluster having a plurality of nodes deployed in a virtualization environment. The limited number of threads (server threads) is constantly maintained as “active” and running on virtual central processing units (vCPUs) of a node. The file system server spawns and organizes the active server threads as one or more pools of threads. The server prioritizes the low-latency I/O requests by loading them onto the active threads and allowing the requests to run on those active threads to completion, thereby obviating overhead associated with lock contention and vCPU migration after a context switch (i.e., to avoid rescheduling a thread on a different vCPU after execution of the thread was suspended).

Abstract: A technique extends a file system infrastructure of a storage system to provide a custom namespace within a pathname of a logical construct configured to invoke semantically interpretative context as a command embedded in a data access protocol request issued by a client and directed to the logical construct served by the storage system, without alteration to the data access protocol. The extension includes a “plug-in” engine of a data access protocol server executing on a network protocol stack of the storage system. The engine operates to extract a pathname from the request to determine whether the custom namespace incorporating the command is present and directed to the logical construct. If so, the engine semantically interprets the command within a context of the custom namespace to essentially convert the command to one or more predefined operations directed to the logical construct. The storage system then performs the operations and returns the results to the client.
