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 8):
A storage system comprising a first device, a second device, a first storage device providing a first block and a second storage device providing a second block, the first device, the second device, the first storage device and the second storage device connected to a switch;\n wherein the first device stores computer readable instructions arranged to cause the first device to perform a copy operation comprising:\n dividing the first and second blocks into an equal number of sub-blocks; \n copying at least one sub-block of the first block to a sub-block of the second block; and \n wherein the computer readable instructions are further arranged to cause the first device to:\n receive through the switch from the second device during the copy operation a first write request indicating first data to be written to the first block; and \n perform a first write operation, the first write operation comprising writing the first data to the first block; \n mark as dirty each sub-block of the first block affected by the write operation; \n perform at least one re-copy operation, each re-copy operation copying one of the sub-blocks of the first block marked as dirty to a sub-block of the second block; \n determine whether a predetermined number of re-copy operations has been performed; \n if it is determined that the predetermined number of re-copy operations has not been performed, performing at least one further re-copy operation; \n if it is determined that the predetermined number of re-copy operations has been performed:\n determine 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 increase a rate at which the re-copy operations are performed or increase the predetermined number of re-copy operations.
