Claim 0:
1. A method comprising:
monitoring condition of optical transceivers at ports of a first data storage node, where the condition comprises at least one of remaining lifespan and signal strength;
monitoring condition of optical transceivers at ports of a second data storage node, where the condition comprises at least one of remaining lifespan and signal strength, ones of the ports of the first data storage node being connected to ones of the ports of the second data storage node as port pairs; and
responsive to a command to migrate data from a source volume of the first data storage node to a target volume of the second data storage node in a future time window:
projecting the condition of the optical transceivers during data migration;
selecting one of the port pairs for transmission of the data based on the projected conditions of the optical transceivers of the ports of the port pair; and
migrating the data via the selected port pair.
