Described are techniques for determining temporary storage areas for logical volumes to be swapped. Logical volumes may be swapped in a computer system in connection with efforts to improve performance of associated data storage entities in the computer system. As part of the data swapping and physical relocation of logical volumes, temporary storage locations are used. A temporary storage location is associated and used with each logical volume being swapped. Determining a temporary storage area for a logical volume may be made in accordance with particular criteria. A temporary storage area is determined for each logical volume from a list of one or more possible candidate locations. The problem of matching a logical volume to a unique temporary storage area may be represented as a bipartite graph matching problem using solutions, such as the maximum flow, and other techniques to find a match for each logical volume.
