摘要： Using a local storage device to read desired data stored on a remote storage device that receives chunks of data from the local storage device includes, if the desired data is entirely in a cache of the local storage device, the local storage device returning the data from the cache and, if the desired data is not entirely in a cache of the local storage device, reading data from the remote storage device to the local storage device and the local storage device merging the data from the remote storage device with data from the local storage device at the local storage device. Using a local storage device to read desired data stored on a remote storage device that receives chunks of data from the local storage device may also include, prior to reading data from the remote storage device to the local storage device, creating a temporary storage area at the local storage device if there is data from the local storage device that is to be read. The temporary storage area may be a scratch slot.

摘要： Reading desired data from a remote storage device that receives chunks of data from an other storage device includes determining if the desired data is part of a chunk of data committed by the other storage device, if the desired data is not part of a chunk of data committed by the other storage device, reading the desired data from a corresponding standard logical device, and if the desired data is part of a chunk of data committed by the other storage device, transferring the desired data to the standard logical device and obtaining the desired data from one of: the standard logical device after transferring the desired data thereto and the chunk of data committed by the other storage device. Reading desired data from a remote storage device may also include, if the desired data is part of a chunk of data committed by the other storage device, locking a corresponding slot of a cache only virtual device that points to the desired data. Reading desired data from a remote storage device may also include, locking a corresponding slot of the standard logical device, merging corresponding cache slots, and causing the corresponding slot of the cache only virtual device to point to the standard logical device.

摘要： Accessing stored data includes providing a virtual storage area having a table of pointers that point to one of: a disk storage area and a volatile memory area, wherein the virtual storage area contains no sections of data, in response to a request for accessing data of the virtual storage area, determining whether a corresponding one of the pointers points to the disk storage area or points to the volatile storage area and accessing the data from the disk storage area or from the volatile storage area. Accessing stored data may also include associating a first one of the other storage areas with the virtual storage area, wherein the virtual storage area represents a copy of data of the disk storage area. Accessing stored data may also include causing all of the pointers of the table to initially point to sections of the disk storage area when the virtual storage area is initially associated with the disk storage area. Accessing stored data may also include, in response to a write to a first section on the disk storage area, copying data of the first section to a second section that is part of the volatile storage area and causing a corresponding one of the pointers of the table to point to the second section.
