Re: Static IP addressing? with Mellanox

[Mark Shuttleworth]

Hi Ed

You might want to look into abusing the mechanisms we provide to record
additional MAC and IP addresses for containers on a machine. The machine
(Juju really) tells MAAS to associate a particular MAC and IP address
with that machine in a way which will then be garbage collected if the
machine is repurposed later.

I think the full fix must be to teach MAAS about Infiniband, which would
mean:

 * the ephemeral image needs to have the necessary drivers to see it
 * we need to record it in the MAAS database as an infiniband device
 * we need to also record if you're going to do IPoverIB
 * the installation needs to set that up

If you're up for this, we'll help steer the patches home. Otherwise, can
put it on the list for 16.10.

I believe this work is in progress between Mellanox and Canonical.

Re: Static IP addressing? with Mellanox

[Narinder Gupta]

Indeed, the IPoIB is part of the Mellanox charm work, as well as the driver
work underneath it all.
We are also pursuing Ceph/RDMA with Mellanox and I'm sure it will also
appear in our Intel relationship.

charms are available at https://code.launchpad.net/~mellanox-canonical
