Subject RE: Question for storage traffic

Hi Chip,

You are absolutely right, configuring a Management Interface on XenServer, using a Primary
Storage CIDR, which is different to the main Management Interface CIDR, will send traffic
destined for Storage over that interface (Bond).

We typically create the Storage Bond with XenCenter before adding the Host to CloudStack,
then after adding the Host, add Primary Storage using the CloudStack API specifying the Primary
Storage IP or FQDN and Cloudstack takes care of the rest.

Regards

Someone feel free to correct me if there is a newer answer...

But yes, if you want to send traffic from the host to primary storage via a dedicated NIC,
I've found that you have to implement the datastore on the host before telling CloudStack
about it.
