Solaris Commands Interview Question:

What is the difference between Vxdmp and EMC powerpath?

Submitted by: Administrator

vxdmp: The way the load balancing done is using round
robin approach
EMC Power path: It does it by knowing which path is
least loaded.
Powerpath will fail back a path once it becomes available.
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 Power
path on AIX and DMP on SUN.
