Abstract:
A method of managing a plurality of storage devices. The method comprises at a first device connected to the plurality of storage devices via a switch, receiving an indication of a plurality of logical disks, each logical disk being provided by a respective one of the plurality of storage devices. Each logical disk comprises a plurality of logical blocks. Data representing a virtual disk is generated, the virtual disk comprising a plurality of virtual blocks, each virtual block being provided by a logical block. Access is provided to the virtual disk to a second device different to the first device. A first virtual block is selected, the first virtual block being provided by a first logical block, and a re-mapping operation is performed after which the first virtual block is provided by a second logical block different to the first logical block.

Claim (Index 1):
A method of copying data from a first block provided by a first storage device to a second block provided by a second storage device, the method comprising:\n dividing the first and second blocks into an equal number of sub-blocks; performing a first copy operation, the first copy operation comprising copying at least one sub-block of the first block to a sub-block of the second block; receiving during the first copy operation a first write request indicating data to be written to the first block; and performing a first write operation, the first write operation writing the first data to the first block; marking as dirty each sub-block of the first block affected by the write operation; performing at least one re-copy operation, each re-copy operation copying one of he sub-blocks of the first block marked as dirty to a sub-block of the second block; determining whether a predetermined number of re-copy operations has been performed; if it is determined that the predetermined number of re-copy operations has not been performed, performing at least one further re-copy operation; if it is determined that the predetermined number of re-copy operations has been performed:\n determining whether a total number of remaining sub-blocks marked as dirty is below a predetermined threshold; and \n if it is determined that the total number of remaining sub-blocks marked as dirty is not below the predetermined threshold increasing a rate at which the re-copy operations are performed or increasing the predetermined number of re-copy operations.
