Makes sense. > IPMI. I see. I wonder...adding an IPMI controller - which has to remain up and running constantly - may end up using as much power as some of the low power ARM boards that you'd be managing in my proposed scenario. Does MAAS only work with IPMI? I'm assuming if you power up a node by some other means, it'll still respond to the net boot request. But really all you need is an ability to power cycle a specific node. Eventually someone will hack together a computer controlled power supply...a bunch of USB jacks, each with its own individually addressable transistor, all controlled by a Pi or Arduino with an Ethernet shield. > - PXE support on ARM hobbist level boards is poor or non-existent...

MAAS can be used to deploy other operating systems to the nodes, no? Do you need to be able to run Ubuntu on the node at least once to enroll it in MAAS? (I see the setup menu for Ubuntu Server has an option to join the machine to a MAAS network.) > "Managing" to MAAS means controlling a pool of PXE-driven devices > that were enlisted under its control, and provisioning what is > installed on them. I didn't get what actually happened when a node was enrolled. I gather there is some communication between the node's IPMI controller and the master node to capture the target node's address? Maybe also capturing the MAC of the node so it can be mapped to the desired OS boot image? > Usually "deployment" or "provisioning" is used in > this context, rather than managing. Sure, MAAS is just dealing with the power up/OS boot/power down aspects, and not management of the node while it is running, like a cloud management tool would. No doubt someone will (or has already) integrate MAAS into a cloud management tool. In some cases it could be used to deploy hypervisors to the bare metal. On other cases you might transparently manage services across a mix of VMs and bare metal. > Hope this helps -Federico Yup, thanks. -Tom _______________________________________________ Hardwarehacking mailing list [email protected] http://lists.blu.org/mailman/listinfo/hardwarehacking
