The following diagram shows the network architecture of this solution:
The following table describes the nodes in the network architecture:
Table 2. Network architecture nodes description
Node | Description |
PowerFlex compute-only node: bond0 | This bond interface is for OS management, CockroachDB management, and PowerFlex management. |
PowerFlex compute-only node: bond1 | This bond interface is for the PowerFlex data network. |
PowerFlex storage-only node: bond0 | This bond interface is for PowerFlex storage management and data network. |
PowerFlex storage-only node: bond1 | This bond interface is for the PowerFlex data network. |
At the physical layer, two supported Top of Rack (TOR) switches are used for redundancy and load-balancing purposes. A peer link is configured on both the TOR switches. VLANs are created to separate different traffic types on the network bonds.
The following table shows the different networks that are configured for this solution.
Network type | VLAN ID |
Operating System (OS) Management | 105 |
PowerFlex Management | 150 |
PowerFlex Data 1 | 152 |
PowerFlex Data 2 | 153 |
CockroachDB internal communication | 154 |
Note: The Operating System Management network must be routable to the PowerFlex Management network to access the PowerFlex cluster.
