SSA disk layout question

I have a 4 SSA disk drawers (no raid) shared between 5 servers and over time as disk gets shuffled from one server to another the disks assigned to a server are not next to each other (ie. disks in drive bay 1, 5 & 6 are assigned to one server while disks 2,3 & 7,8 are assigned to another server for example). The question is should I take the time to move those disks together (I guess it depends on IO load I'm seeing now and if that's an issue or not)? I know ideally they would be in the proper location depending on where the ssa cable connects also. I was thinking of doing some migratepv stuff by using an unassigned disk but that's kind of time consuming so I was thinking a physical drive bay swap is probably the fastest way of doing this during a downtime. I guess the real question is should I bother and if I do am I missing anything if i think I can just swap the drives around without any problems. I know I'll have some diocumentation to update to show what hdisks are assigned to which servers... MS
