[Xen-users] DRBD, Heartbeat and Infiniband

["Robert Dunkley" <Robert@xxxxxxxxx>]

Hi Everyone,

 

I’m a bit of a beginner with this so please let me know if the questions are stupid (I have played with Xen under Centos for a little while and have some working images).

 

I’m about to try setting up a pair of servers with Server A cloning the disks on Server B using DRBD. As far as I can tell DRBD has native support for Xen using the drbd: disk type (Lots of outdated documentation out there it seems) but there are a couple of things I’m unsure of:

How do I configure heartbeat to work with this?

Is DRBD 8.0 recommended? (8.2 seems to cause problems from what I’ve read)

Is Xen NUMA aware? (If so does it need separately enabling/compiling?)

 

I also want to use a dedicated Infiniband connection to clone the disk data using DRBD. Is IP over Infinband with DRBD the best way to do this or is there a more efficient method?

 

Thanks,

 

Rob
