A method, apparatus and system for providing access to data comprising launching an image of a virtual machine, determining a file system or a storage container being unsupported by an operating system coupled to the virtual machine, mapping the file system or the storage container onto the operating system and accessing data within the file system or the storage container through the operating system.

Method and apparatus for providing access to data in unsupported file systems and storage containers

A method and apparatus for pre-fetching data to be streamed from a data storage to a user computer comprising the steps of determining information regarding a file type of a data file, establishing pre-fetch parameters in response to the information, accessing the data file and pre-fetching data blocks from the data file in accordance with the pre-fetch parameters is described.

Method and apparatus for prefetching data

A method and apparatus for controlling access to a storage area network among a group of hosts in a distributed computing environment. A host requests access to the storage area network by issuing an input/output request, and the input/output request is intercepted at the dynamic multipath (DMP) layer. The DMP layer checks the input/output request against an access control list. The DMP layer can grant or deny the input/output request from the host system. If the input/output request is granted, then the DMP layer passes on the input/output request to the HBA driver layer and the host is allowed to access the storage area network. If the request to access the storage area network is denied, the DMP management layer can initiate an appropriate response, such as a security procedure or generation of an error message alerting a user the request has been denied.

Method and apparatus for controlling access to a storage area network

A method and apparatus for a virtual storage device is provided. In one example, data to be stored at a removable storage device is received. A virtual storage agent is executed on the removable storage device. An interlace is established with at least one remote storage location. The data is stored at the at least one remote storage location. In another example, a request to access data associated with a removable storage device is received. A virtual storage agent on the removable storage device is executed. An interface is established with at least one remote storage location. The data is fetched from the at least one remote storage location.

Method and apparatus for a virtual storage device

A method, apparatus, system and computer program product that provide a virtual worldwide name (vWWN) nameservice in a Fiber Channel storage area network (SAN) are provided. Embodiments of the vWWN nameservice can receive a request for a vWWN from a node in the SAN, where the request includes a identifier associated with resources in the SAN, then determine if the identifier matches contents of a field in one or more entries in a vWWN table or database, and provide the vWWN associated with a matching entry to the requesting node.

Flexibly provisioning and accessing storage resources using virtual worldwide names

A system and method for writing and reading blocks of a data volume are disclosed. The method provides continuous data protection (CDP) for a data volume by backing up blocks of the data volume in real time to a local CDP log and transmitting the blocks over the Internet for storage in a remote CDP log on a server computer system in response to write requests that change the blocks of the data volume. In response to a read request for a particular block the method attempts to read the block from the data volume. If the block is not present in the data volume the method attempts to read the block from the local CDP log. If the block is not present in the local CDP log the method request the server computer system to read the block from the remote CDP log and return the block.

Continuous data protection and remote block-level storage for a data volume

A method and apparatus for providing flexible access to storage resources in a storage area network is provided. One aspect of the invention relates to managing hosts and storage resources on a storage area network. At least one logical relationship among the storage resources is associated with each of a plurality of virtual identifiers. At least one of the plurality of virtual identifiers is then associated to an interface of each of the hosts.
