Is Sun StorageTek Traffic Manager supported on servers connected to VMAX and CX4?
Hello All,
I am having some performance issues on a Solaris server using VMAX and CX4 disks , the server is using Sun StorageTek Traffic Manager as Multipath software, I am wondering If this could be the problem.
Thanks.

Do you see any errors related to i/o in /var/adm/messages file?
With performance issues it's always good if you can rule out the environment and make sure that there are no aborts, timeouts or any other transport errors.
Then is it possible for you to narrow down which device(s) the performance issue is related to? It's possible that the devices are not equally utilized but this information will also help determine the origin of the issue, or at least rule out a few possibilities.
