Abstract
A virtual storage unit from one data storage system may be migrated to another data storage system. Utilization impacts on system resources by one or more virtual storage units on multiple data storage systems may be quantified, for each data storage system as a whole, or for a functional component of each data storage system. Based on these quantifications, multiple “what-if” scenarios may be considered to determine the consequences of migrating one or more virtual storage units from one of the data storage systems to another one of the data storage systems. If it is determined that a virtual storage unit is to be migrated, a live migration may be performed such that one or more hosts maintain access to the data of the virtual storage unit while the virtual storage unit is being migrated.
