EMC Powerpath Vs Veritas DMP
- Thread starter sai100
- Start date
My knowledge of DMP is going back a couple of years here but....
Basically the big difference is how the software handles load balancing between the paths. DMP does it through a round robin approach and Powerpath does it by knowing which path is the least loaded. Also Powerpath will fail back a path once it becomes avaliable. The older version of DMP that we were using on Solaris you had to manually bring back the other path. This could have just been the limitations of Solaris as well. We ran Powerpath on AIX and DMP on SUN. Hope this helps.
