An apparatus comprises at least one processing device coupled to memory. The at least one processing device is configured to obtain a secured disk image comprising an encrypted manifest file, an encrypted install binary and a plurality of other files. The at least one processing device is further configured to obtain a certificate corresponding to the secured disk image and to derive a public key based at least in part on the certificate. The at least one processing device is further configured to decrypt the manifest file and the install binary based at least in part on the public key and to validate checksums for respective ones of the plurality of other files against corresponding checksums contained in the decrypted manifest file. The at least one processing device is further configured to execute the decrypted install binary responsive to validation of the checksums for the respective ones of the plurality of other files.

Virtual host upgrade using a secured disk image

A method of retrieving data blocks in a storage area network, the method comprising selecting a first one of a plurality of paths to a storage device; retrieving a first number of sequential data blocks from the storage device along the first path; and selecting a second one of the plurality of paths for retrieving subsequent sequential data blocks from the storage device. One or both of the selected paths may be the path with the lowest average turnaround time of all of the available paths.

Data processing method and system

The invention relates to a system and method for prioritizing one or more data processing operations in a computer storage system, the computer storage system including a plurality of modules, the method comprising receiving a command indicating one or more data processing operations to which priority is to be assigned and interfacing with each of the modules so as to prioritize the one or more data processing operations over other data processing operations.
