1. A computer-implemented method of managing a paging space device in a data processing system, the method comprising: managing a paging storage pool comprising one or more physical storage devices for holding logical memory pages external to physical memory of the data processing system, the managing, comprising: automatically defining a logical volume in the paging storage pool from block storage for use as said paging space device for a new logical partition, the automatically defining occurring absent use of a filesystem, wherein the said paging space device is other than a file in a filesystem; and automatically specifying the logical volume as the paging space device for the new logical partition and binding the paging space device to the new logical partition, wherein the logical volume is sized with reference to a defined maximum memory size of the new logical partition.
