摘要： Described herein is technology for, among things, a distributed transaction system. The distributed transaction system includes a number of computing entities and a data storage unit in communication with the computing entities. The data storage unit is operable to store a file system that is accessible by the computing entities. The data storage unit is also operable to store a number of transaction journals corresponding to respective computing entities. The transaction journals describe transactions of the computing entities on the file system. A particular computing entity is operable to maintain a respective transaction journal without communicating with the other computing entities.

摘要： The storage system exports logical storage volumes that are provisioned as storage objects. These storage objects are accessed on demand by connected computer systems using standard protocols, such as SCSI and NFS, through logical endpoints for the protocol traffic that are configured in the storage system. To facilitate creation and management of logical storage volumes, special application programming interfaces (APIs) have been developed. The special APIs include commands to create a logical storage volume, bind, unbind, and rebind the logical storage volume, extend the size of the logical storage volume, clone the logical storage volume, and move the logical storage volume.

摘要： The storage system exports logical storage volumes that are provisioned as storage objects. These storage objects are accessed on demand by connected computer systems using standard protocols, such as SCSI and NFS, through logical endpoints for the protocol traffic that are configured in the storage system. When a virtual machine is provisioned, logical storage volumes include a logical metadata storage volume and logical data storage volumes. The logical metadata storage volume stores metadata for the virtual machine such as configuration and log files, swap file, and disk descriptor files. Each disk descriptor file is provided for one logical data storage volume and stores metadata about the logical data storage volume such as size and unique identifying data.

摘要： The storage system exports logical storage volumes that are provisioned as storage objects. These storage objects are accessed on demand by connected computer systems using standard protocols, such as SCSI and NFS, through logical endpoints for the protocol traffic that are configured in the storage system. Prior to issuing input-output commands to a logical storage volume, the computer system sends a request to bind the logical storage volume to a protocol endpoint. In response a first identifier for the protocol endpoint and a second identifier for the logical storage volume is returned. Different second identifiers may be generated for different logical storage volumes even though the same protocol endpoint is being used. Therefore, a single protocol endpoint may serve as a gateway for multiple logical storage volumes.

摘要： The storage system exports logical storage volumes that are provisioned as storage objects. These storage objects are accessed on demand by connected computer systems using standard protocols, such as SCSI and NFS, through logical endpoints for the protocol traffic that are configured in the storage system. When traffic through a particular protocol endpoint is busy, the logical storage volume undergoes a rebind process pursuant to which the logical storage volume is bound to a new protocol endpoint, and the binding to the old protocol endpoint is removed upon completion of all pending input-output commands issued through the old protocol endpoint.

摘要： The storage system exports logical storage volumes that are provisioned as storage objects. These storage objects are accessed on demand by connected computer systems using standard protocols, such as SCSI and NFS, through logical endpoints for the protocol traffic that are configured in the storage system. When an input-output command (IO) is received at the storage system, an identifier is retrieved from the IO and translated into a logical storage volume identifier, and the IO is executed on storage locations referenced by a logical storage volume corresponding to the logical storage volume identifier.

摘要： Metadata of a shared file in a clustered file system is changed in a way that ensures cache coherence amongst servers that can simultaneously access the shared file. Before a server changes the metadata of the shared file, it waits until no other server is attempting to access the shared file, and all I/O operations to the shared file are blocked. After writing the metadata changes to the shared file, local caches of the other servers are updated, as needed, and I/O operations to the shared file are unblocked.

摘要： Replicated data storage units are autonomously identified and assembled into generationally related data storage volumes. A data storage manager, implementing a re-signaturing process executed at defined intervals or manually initiated on a server or client system connected to the storage area network, scans the collection of visible data storage units to identify those related as a data storage volume. Each replicated data storage unit includes metadata that embeds an identification of the replicated data storage unit and volume accessible to the data storage manager. To assemble a set of replicated data storage units into a generational volume, the data storage unit metadata is rewritten to establish a unique data storage volume identity including information to associate the data storage volume in a lineage with the source data storage volume.

摘要： Interfaces to storage devices that employ storage space optimization technologies, such as thin provisioning, are configured to enable the benefits gained from such technologies to be sustained. Such an interface may be provided in a hypervisor of a virtualized computer system to enable the hypervisor to discover features of a logical unit number (LUN), such as whether or not the LUN is thinly provisioned, and also in a virtual machine (VM) of the virtualized computer system to enable the VM to discover features of a virtual disk, such as whether or not the virtual disk is thinly provisioned. The discovery of these features enables better management of the LUN during near full and out-of-space conditions.
