Abstract: A physical host machine determines that a storage device from a network storage system is available to the host machine as a pass-through disk. Virtualization software running on the host machine assigns the pass-through disk to a temporary resource group on the host machine. The pass-through disk is logically attached to the virtual machine running on the host machine and made available to an operating system and application running on the virtual machine.

Abstract: The techniques introduced here provide a storage server migration that is non-disruptive to client applications. The techniques described here allow the migration of data from a source storage server to a destination storage server without the need for planned downtime typically associated with storage server migration. Using the techniques described here, data migration operations are performed while client applications continue to run and access data from the source storage server. Once data migration operations are complete, all applications and clients are transitioned to the destination storage server without disruption to the client applications.

Abstract: A system and method for application aware de-duplication of data blocks in a virtualized storage array is disclosed. In one embodiment, in a method of de-duplication of data, a master list of metadata is created based on a number of occurrences of data blocks within a storage array. A first sublist of metadata is created from the master list of metadata. The first sublist of metadata is provided to a first component of a networked storage system. It is determined whether the data block being written has a corresponding entry in the master list of metadata based on a determination that a data block being written does not have any corresponding entry in the first sublist of metadata. The data block being written is replaced with a pointer based on a determination that the data block being written has a corresponding entry in the master list of metadata.

Abstract: A system for controlling power usage in a storage cluster by dynamically controlling membership in the storage cluster is disclosed. The storage cluster includes multiple storage servers that provide access to one or more storage subsystems. The power management system uses a power management policy to set parameters for controlling membership in the storage cluster and monitors the storage cluster based on the policy. Based on the monitoring, the system detects when the number of storage servers in the storage cluster should be reduced or increased. To reduce the number, the system selects a storage server to deactivate and directs the selected storage server to migrate storage resources (e.g., data, metadata) associated with the server to a different storage server. The system then deactivates the selected storage server by directing it to transition to a low power mode. The system may increase the number of servers in the storage cluster by reversing these steps.

Abstract: Systems and methods for performing a fast resynchronization of a mirrored aggregate of a distributed storage system using disk-level cloning are provided. According to one embodiment, responsive to a failure of a disk of a plex of the mirrored aggregate utilized by a high-availability (HA) pair of nodes of a distributed storage system, disk-level clones of the disks of a healthy plex may be created external to the distributed storage system and attached to the degraded HA partner node. After detection of the cloned disks by the degraded HA partner node, mirror protection may be efficiently re-established by assimilating the cloned disks within the failed plex and then resynchronizing the mirrored aggregate by performing a level-1 resync of the failed plex with the healthy plex based on a base file system snapshot of the healthy plex. In this manner, a more time-consuming level-0 resync may be avoided.

Abstract: A method, non-transitory computer readable medium and storage server computing device that stores an identifier for a file system block evicted from a buffer cache in an entry in a table. The file system block is inserted into a victim cache hosted by an ephemeral block-level storage device by invoking a function provided by an application programming interface (API). The API exposes the ephemeral block-level storage device to a virtual storage appliance via an operating system of the storage server computing device. The entry in the table is updated to include location(s) on the ephemeral block-level storage device at which one or more portions of the file system block are stored, the location(s) returned in response to the function invocation. By this technology, performance of the virtual storage appliance is significantly improved, resulting in lower latency for client devices requesting data in a cloud storage environment.

Abstract: Described herein are systems, methods, and software to provide ransomware detection using variable levels of encryption. In one implementation, a computing device identifies a set of files, wherein the set of files each comprise a label indicative of whether the file is representative of a safe file or a file attacked by ransomware, and wherein the set of files comprises unencrypted files, partially encrypted files, and fully encrypted file. The computing device further identifies features associated with the set of files and generates a machine learning model that outputs a determination of whether a new file has been attacked based at least on the features in relation to whether a file in the set of files was labeled as attacked.
