Re: Mixing Netapp and EMC in a SAN environment - toasters

16 Feb 2006


      Doesn't netapp use Veritas DMP for its multipathing?  Is this environment using EMC Powerpath for multipathing?  I've never heard of anyone trying it, but I've always wondered if there is any kind of conflict between using Veritas DMP and powerpath on the same host, even if using different HBAs for accessing the two different vendor's storage

The one thing to be careful of is having conflicts with the multipath drivers. Sometimes they can battle over the FC card if a failure occurs. 
The safest bet is to have a dedicated HBA pair per storage subsystem.

Never heard of anyone doing that, per se.
Performance issues? I can't really think of any that would be 
different than striping across two EMC or NetApp arrays. If the 
back-end storage is behaving as it should, all should be fine J

All,
Did anyone use both EMC and Netapp in a combined SAN environment where 
one solaris host mounts luns from both EMC and Netapp..
It does work but iam more concerned about any performance issues wrt 
to Veritas volume manager stripping across luns from EMC and Netapp..
Really appreciate your input..
