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. 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. 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： 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 the hypervisor or the VM to instruct the underlying storage device to carry out certain operations such as an operation to deallocate blocks previously allocated to a logical block device, so that the storage device can continue to benefit from storage space optimization technologies implemented therein.

摘要： Provided are methods, apparatus and computer programs for identifying vulnerabilities to viruses of hacking. Hash values are computed and stored for resources stored on systems within a network. If a first resource or a collection of resources (such as files comprising an operating system, Web Browser or mail server) is associated with a vulnerability, hash values for the first resource or collection of resources are compared with the stored hash values to identify systems which have the vulnerability. Messages may be sent to the people responsible for the vulnerable systems, or the vulnerability may be removed by automatic downloading of patches or service packs.

摘要： Provided are methods, apparatus and computer programs for identifying matching resources (data files and executable files) within a data processing network, by comparison of hash values computed for each of a set of resources. A match between a newly computed hash value and a previously computed hash value for a resource indicates that the resource has not changed since the previous computation. A match between hash values for different resources indicates that they are identical. The result of the comparison can be used to determine whether a virus scan is currently required for a resource, on the basis that a resource which is unchanged since it was classified virus-free remains virus-free and a resource which is identical to a virus-scanned resource does not require duplication of the virus scan. The methods, apparatus and computer programs enable more efficient use of antivirus scanning or management of a backup copy process.

摘要： Provided are methods, apparatus and computer programs for enhanced access to resources within a network, including for controlling use of bandwidth-sensitive connections within a network and/or for automated recovery. Hash values are used as ‘unique’ identifiers for resources distributed across a network, and each one of a set of pool servers store the hash values for a set of computers within a LAN. When a resource is required, a hash value representing the resource can be retrieved and compared with hash values stored at a pool server to determine whether the pool server holds a matching hash value. Any such matching hash value found on the pool server represents an identification of a local copy of the required resource, because of the uniqueness property of secure ash values. The information within the pool server can be used to access the required resource. If a large resource such as a BLOB or new version of a computer program can be obtained from another computer within a LAN, a reduction in reliance on bandwidth-sensitive Internet connections and reduced load on remote servers becomes possible.
