1.2. spine-leaf network topology
spine-leaf 场景利用 OpenStack Networking(neutron)功能定义单个网络段内的多个子网。每个网络都使用充当 Leaf 0 的基础网络。director 将 Leaf 1 和 Leaf 2 子网创建为主网络的片段。
这种情境使用以下网络:
表 1.1. leaf 0 Networks(基础网络)
| Network | 附加角色 | 子网 |
|---|---|---|
| provisioning / Ctlplane / Leaf0 | controller, ComputeLeaf0, CephStorageLeaf0 | 192.168.10.0/24 |
| 存储 | controller, ComputeLeaf0, CephStorageLeaf0 | 172.16.0.0/24 |
| StorageMgmt | controller, CephStorageLeaf0 | 172.17.0.0/24 |
| InternalApi | controller, ComputeLeaf0 | 172.18.0.0/24 |
| 租户 [1] | controller, ComputeLeaf0 | 172.19.0.0/24 |
| 外部 | Controller | 10.1.1.0/24 |
[1]租户网络也称为项目网络。
表 1.2. leaf 1 Networks
| Network | 附加角色 | 子网 |
|---|---|---|
| provisioning / Ctlplane / Leaf1 | ComputeLeaf1, CephStorageLeaf1 | 192.168.11.0/24 |
| StorageLeaf1 | ComputeLeaf1, CephStorageLeaf1 | 172.16.1.0/24 |
| StorageMgmtLeaf1 | CephStorageLeaf1 | 172.17.1.0/24 |
| InternalApiLeaf1 | ComputeLeaf1 | 172.18.1.0/24 |
| TenantLeaf1 [1] | ComputeLeaf1 | 172.19.1.0/24 |
[1]租户网络也称为项目网络。
表 1.3. leaf 2 Networks
| Network | 附加角色 | 子网 |
|---|---|---|
| provisioning / Ctlplane / Leaf2 | ComputeLeaf2, CephStorageLeaf2 | 192.168.12.0/24 |
| StorageLeaf2 | ComputeLeaf2, CephStorageLeaf2 | 172.16.2.0/24 |
| StorageMgmtLeaf2 | CephStorageLeaf2 | 172.17.2.0/24 |
| InternalApiLeaf2 | ComputeLeaf2 | 172.18.2.0/24 |
| TenantLeaf2 [1] | ComputeLeaf2 | 172.19.2.0/24 |
[1]租户网络也称为项目网络。
