[Lustre-discuss] bonding and multiple OST per OSS

[Brock Palen]

Hello,
In reading the manual about bonding (we will need to bond our Gige)   
I get the impression that we should let lustre take care of it and  
not use the linux bonding drivers.  Am I correct in this assumption?   
If so I would have 2 interfaces each with their own IP,  how does the  
client know to use both interfaces?  Is this just advertised by the  
MGS to the client when mounted?  Or does a client choose a random  
interface and does all IO to that OSS though that interface for that  
transaction?

Also our OSS will have 2 separate devices,  I would like to be  
separate stripe targets for lustre.  (ie if using 1 OSS lfs  
getstripe, would show a large files striped over 2 OST's)  Is this  
fine?  or should we software raid them together and make one large  
OST on top?

Thank you
