The following figure shows the architecture of an HCP system that uses internal storage. This system has four storage nodes, two back-end switches (on the left), and two front-end switches (on the right).
The following table describes the cables in this figure.
| Cable | Connects from | Connects to |
|---|---|---|
| Red and blue Ethernet | Back-end network interface cards (NICs) in each node | Back-end switches |
| Green and yellow Ethernet | Front-end NICs in each node | Front-end switches |
| Purple Ethernet | Back-end switches | Each other |
| Black power | Each node | Two PDUs |
| Each back-end switch | One PDU |
