Abstract: Techniques for performing fine-grained metadata management in a distributed file system (DFS) are provided. In one embodiment, each node in a plurality of nodes implementing the DFS can execute a namespace metadata service that is dedicated to managing file system metadata pertaining to one or more namespaces of the DFS. Each node can further execute a data metadata service that is distinct from the namespace metadata service, where the data metadata service is dedicated to managing file system metadata pertaining to properties of data and free space in the DFS.

Abstract: A method for allocating storage for a virtual machine includes receiving a request to allocate a block of disk storage on a physical disk to a virtual disk associated with the virtual machine. The method also includes identifying a plurality of available blocks on the physical disk, each of the plurality of available blocks defining a radial distance from a center axis of a platter of the physical disk. The method further includes determining which of the plurality of available blocks has a greatest radial distance from the center axis of the platter and, based on the determining, selecting an allocation block from the plurality of available blocks, the allocation block having the greatest radial distance from the center axis of the platter. The method also includes allocating the allocation block to the virtual machine.

Abstract: Processing in an asymmetrically distributed file system may include storing first data representative of the content of the files in a file system volume among a plurality of storage nodes. Second data representative of attributes of the files in the file system volume may be stored in only one of the storage nodes. Time-limited leases allow clients direct access to the plurality of storage node in order to access portions of the file system volume. The time-limited leases may be provided to client lessors. Snapshots of the file system volume may be generated after sending a revocation to the client lessors to revoke time-limited leases provided to the client lessors and having received the acknowledgements of the revocations or after the leases have expired for non-responding lessors, to ensure that changes are not made to the file system volume during snapshot processing.

Abstract: Examples perform input/output (I/O) requests, issued by a plurality of clients to an owner-node, in a virtual storage area network (vSAN) environment. I/O requests are guaranteed, as all I/O requests are performed during non-overlapping, exclusive sessions between one client at a time and the owner node. The owner node rejects requests for simultaneous sessions, and duplicate sessions are prevented by requiring that a client refresh its memory state after termination of a previous session.

Abstract: An example method to allocate a virtual disk for a virtual machine in a virtualized computing system includes allocating a plurality of virtual machine disk file (VMDK) candidates in a virtual machine file system (VMFS) volume, selecting a subset of VMDK candidates from the plurality of VMDK candidates for having performance scores indicative of higher I/O throughputs associated with the one or more physical hard disks than rest of the plurality of VMDK candidates, and configuring the virtual disk based on the subset of the VMDK candidates. The VMFS volume is supported by one or more physical hard disks in a storage system in the virtualized computing system.
