| 1. A method comprising:
receiving topology information for a storage area network, the storage area network associated with a virtual logical unit
number (VLUN) including a plurality of host initiators, a plurality of targets, and a plurality of candidate virtualization
engines;
determining latency characteristics for performing input/output (I/O) operations between the plurality of host initiators
and the plurality of targets using the candidate virtualization engines;
determining mirroring and striping characteristics associated with the VLUN; and
selecting a virtualization engine from the plurality of candidate virtualization engines for the VLUN based on the average
latency and the mirroring and striping characteristics.
