I am new to the openstack. I have question regarding to
This design shown a two controller nodes, one brand iSCSI DAS and a
lot of compute nodes. Controller nodes has small local storages and
connectivity to iSCSI DAS. Compute nodes, according to "Rule of
Thumb): 4 to 8 GB RAM and 1 Spindle Per Core", has a lot of local
spaces each one.
So how work Nova-volumes here? It is running on controller node and
use VG "nova-volumes" which based on disk via attached iSCSI DAS?
After that euca-create-volume create volume and will expose it to the
compute node via iSCSI again? If it is correct, what is the point to
use huge local storages at compute nodes, for boot image of instances
