[URL]  Before adding paths or moving VMs, I would change this parameter if it is not already.  If you still have issues, I think going to 6 or 8 paths would be a better option than splitting the servers.  To me it would be easier to manage.
We have a VM infrastructure where we are supposed to provide luns of large sizes ranging from 1.2TB - 2TB.  Now my question is:   I am trying to understand whenever some one asks me to provide a lun size of 1.2 TB or 1.5 TB or 2 TB, how would i select my options (since symmetrix provides me with a range of options to form meta devices) for the best performance.Also if some one can help me out with any white papers which explains best practice for virtual provisioning.
