This is an overview of the DCN deployment process that can be utilized for planning purposes:
- Rack and stack
- Cabling
- iDRAC setup
- PXE NIC configuration
- Server BIOS and RAID configuration
- Switch configuration
2. Software setup at each DCN site:
- Install a DCHP relay(s) used to forward DCHP traffic to Neutron running on the central cloud control plane
- At least one DCHP relay is required for provisioning compute nodes at the DCN site
- Where the DHCP relay(s) are installed is up to the customer
- Discover edge site nodes
- Import discovered nodes into Red Hat OpenStack Director
- Configure Overcloud files for each DCN site
- Provision DCN site
- Validate DCN nodes' networking
Environment tests
- Once Red Hat OpenStack Director has completed a DCN site deployment, a typical set of validation tasks will include:
-
Create a flavor, with the supporting metadata to target the DCN site when launching an instance,
for example:$ openstack flavor create --property dcn-site-1=true dcn-site-1- flavor +----------------------------+--------------------------------------+ | Field | Value | +----------------------------+--------------------------------------+ | id | 4bc6c3e7-42be-4620-ae84-819459baf496 | | name | dcn-site-1-flavor | | os-flavor-access:is_public | True | | properties | dcn-site-1='true' | +----------------------------+--------------------------------------+
- Launch an instance using the new flavor and DCN site provider network, for example:
$ openstack server create --flavor dcn-site-1-flavor \ --network dcn-site-1-provider-net dcn-site-1-vm-1 ... +-----------+---------------------------------------+ | Field | Value | +-----------+---------------------------------------+ | flavor | dcn-site-1-flavor (4bc6c3e7-42be-...) | | hostId | 2ef6c3e7-32ae-2120-ae84-819459baf488 | | name | dcn-site-1-vm-1 | | addresses | dcn-site-1-provider-net=192.168.1.123 | | ... | ... | +--------+------------------------------------------+
- Validate instance is running and that networking and addressing is correct.
