This is an overview of the DCN deployment process that can be utilized for planning purposes:
- Hardware setup:
- Rack and stack
- Cabling
- iDRAC setup
- PXE NIC configuration
- Server BIOS and RAID configuration
- Switch configuration
- 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
- Install a DCHP relay(s) used to forward DCHP traffic to Neutron running on the central cloud control plane
- Environment tests
- Once Red Hat OpenStack Director has completed a DCN site deployment, a typical set of validation tasks will include:
- Create a flavor ,
- 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' |
+----------------------------+--------------------------------------+
- Create a flavor with the supporting metadata to target the DCN site when launching an instance, for example:
- Launch an instance ,
- 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 |
| ... | ... |
+--------+------------------------------------------+
- Launch an instance using the new flavor and DCN site provider network, for example:
- Validate instance ,
- Validate instance is running and that networking and addressing is correct.
