Brocade 300 and logical partitions

are you talking about VIO ?

If you are just talking LPARs, we have each LPAR assigned it's own physical HBAs. As far as anything outside the server is concerned the multiple LPARs appear to be separate physical servers. This goes for switches and arrays. I'm not sure if there is any other way to do it with Physical LPARs.

If you are talking about VIO... the VIO LPARS each get their own physical HBAs (just like physical LPARs (which they are). The client LPARs get their storage through the VIO LPARs so don't actually need to know anything about the SAN (and the SAN doesn't need to know about them). The SAN allocations are done to the VIO LPARs, then the storage is passed on to the Client LPARs.

Hope this helps.

Thanks for all the answers.

Definitely, I was talking about VIO.

If I have well understood, the SAN knows the physical LPAR (HBA),

the zoning as well. The clients LPARs get their storage through VIO.

Absolutely :-)

So in our case we use PowerPath on the VIO LPARs (always with two VIO LPARS to ensure uptime). The client LPARs just use MPIO because the load balancing is already handled at the VIO LPAR level. They just need basic failover at the client LPAR level. This works very well for us.
