In one embodiment, a system for managing a virtualization environment includes a set of host machines, each of which includes a hypervisor, virtual machines, and a virtual machine controller, and a data migration system configured to identify one or more existing storage items stored at one or more existing File Server Virtual Machines (FSVMs) of an existing virtualized file server (VFS). For each of the existing storage items, the data migration system is configured to identify a new FSVMs of a new VFS based on the existing FSVM, send a representation of the storage item from the existing FSVM to the new FSVM, such that representations of storage items are sent between different pairs of FSVMs in parallel, and store a new storage item at the new FSVM, such that the new storage item is based on the representation of the existing storage item received by the new FSVM.

Technologies are provided to ensure integrity of erasure coded data that is subject to read and write access from distributed processes. Multiple processes that access erasure coded data can be coordinated in an efficient, scalable and fault-tolerant manner so that integrity of the original data is maintained. The Technologies include a fault-tolerant access coordination protocol that ensures exclusive write access by a client. The coordination protocol achieves scalability by not relying on centralized components, and achieves efficiency and performance by piggy-packing access coordination messages on operations of the underlying erasure coding protocol.

Methods and apparatuses are described for secure compliant storage of server access data. A server computing device generates one or more access logs based upon data access requests executed on a first compliant data storage container comprising a plurality of files. The server computing device stores the one or more access logs in a non-compliant data storage container and establishes a second compliant data storage container. The server computing device retrieves, from the non-compliant data storage container, the access logs stored therein and stores the access logs in the second compliant data storage container.

In one embodiment, a system for managing communication connections in a virtualization environment includes a plurality of host machines implementing a virtualization environment, wherein each of the host machines includes a hypervisor, at least one user virtual machine (user VM), and a distributed file server that includes file server virtual machines (FSVMs) and associated local storage devices. Each FSVM and associated local storage device are local to a corresponding one of the host machines, and the FSVMs conduct I/O transactions with their associated local storage devices based on I/O requests received from the user VMs. Each of the user VMs on each host machine sends each of its respective I/O requests to an FSVM that is selected by one or more of the FSVMs for each I/O request based on a lookup table that maps a storage item referenced by the I/O request to the selected one of the FSVMs.

An electronic device includes: a memory storing a database, a journal file for the database, and instructions; and a processor electrically connected with the memory. The instructions are configured to, when executed by the processor, cause the electronic device to: record a result of processing a transaction in the journal file through a thread of a process associated with the database; identify a size of the journal file through the thread; perform a lock for the journal file during a reference time through the thread, based on the identified size of the journal file through the thread; and transfer the result of processing the transaction to the database through the thread, based on a success of the lock for the journal file, the result of processing the transaction being recorded in the journal file.

A versioned file system comprising network accessible storage is provided. Aspects of the system include globally locking files or groups of files so as to better control the stored files in the file system and to avoid problems associated with simultaneous remote access or conflicting multiple access requests for the same files. A method for operating, creating and using the global locks is also disclosed. A multiprotocol global lock can be provided for filing nodes that have multiple network protocols for generating local lock requests.

An interface server (e.g., Web Application Open Platform Interface (WOPI) server) is communicatively connected to an information management (IM) server and to an online application server which acts as a client of the interface server. When a user wishes to open, create, or edit a document in an online application hosted by the online application server, the interface server is called, instead of the IM server which manages the document at the backend of an enterprise computing network. The interface server is configured for obtaining a working copy of the document from the IM server and providing the working copy to the client. The client provides the working copy to the online application for display on the user device. When the work is done, the working copy is sync'd back through the interface server to the IM server as a new draft and deleted by the interface server.

A method of synchronously executing input/output operations (IOs) for a plurality of applications using a storage device with a file system includes the steps of: receiving a first write IO including an instruction to write first data at a first address of the file system; determining that, within a first range of the file system comprising the first address, there are no pending unmap IOs for deallocating storage space of the storage device from files of the plurality of applications; after determining that there are no pending unmap IOs within the first range, locking the first range to prevent incoming unmap IOs from deallocating storage space within the first range from the files of the plurality of applications; after locking the first range, writing the first data to the storage device at the first address; and after writing the first data, unlocking the first range.

File system management is disclosed. File system metadata is stored in local memory of a client. The portion of local memory storing the file system metadata is under control of the metadata server. The construction and management of the metadata stored in the local memory of the client is driven, initiated and managed by the remote metadata server.

Disclosed are mechanisms for sharing content through content consumption systems. A sharing module publishes content in a share and metadata associated therewith to a content consumption system external to a managed repository. The share represents a folder or directory in the managed repository. The publication can be made through application programming interface (API) calls handled by a first sharing module API, a repository API, a second sharing module API, and a content consumption system API. These APIs together provide a one-to-one mapping of communications protocols used by the managed repository and the external system. The share in the managed repository and the share published to the content consumption system are synced and any conflict between the two is detected and resolved. The shared content can be repatriated back to the managed repository and the shared version deleted from the content consumption system.
