摘要： Embodiments of the invention provide methods and systems for improving the reliability of data stored on disk media. Logical redundancy is introduced into the data, and the data within a logical storage unit is divided into sectors that are spatially separated by interleaving them with sectors of other logical storage units. The logical redundancy and spatial separation reduce or minimize the effects of localized damage to the storage disk, such as the damage caused by a scratch or fingerprint. Thus, the data is stored on the disk in a layout that improves the likelihood that the data can be recovered despite the presence of an error that prevents one sector from being read correctly.

摘要： A computer system (a method) for providing storage management solution that enables server virtualization in data centers is disclosed. The system comprises a plurality of storage devices for storing data and a plurality of storage management drivers configured to provide an abstraction of the plurality of the storage devices to one or more virtual machines of the data center. A storage management driver is configured to represent a live disk or a snapshot of a live disk in a virtual disk image to the virtual machine associated with the driver. The driver is further configured to translate a logical address for a data block to one or more physical addresses of the data block through the virtual disk image. The system further comprises a master server configured to manage the abstraction of the plurality of the storage devices and to allocate storage space to one or more virtual disk images.

摘要： Embodiments provide permanent storage space for data available via network file access protocols. Client machines connect to the permanent storage appliance. The permanent storage appliance stages data to create an optical image according to a policy. The optical images are recorded on media and stored in a permanent media library that is accessible via the network.
