Re: [dm-devel] Req: Details on Multipath-i/o FX-HBA



Hi,

> release their own products like (powepath- from EMC.).

afaik EMC doesn't develope powerpath for 2.6. The companies usually support 
their own stuff, something that you usually won't get from them for 
multipath. But afaik you'll get the support from Redhat and Novell/Suse for 
their Enterprise server edition.

> 2. What is main difference between these two?

multipath is open source (which means it is free), the others not - you'll 
have to pay money for them usually.
