The following figure shows the architecture of an HCP system that uses a Fibre Channel SAN array. This system has four storage nodes, two modular storage trays, two back-end switches (on the left), and two front-end switches (on the right). Each node has multipathed access to the shared SAN storage.
The following table describes the cables in this figure.
| Cable | Connects from | Connects to |
|---|---|---|
| Red and blue Ethernet | Back-end 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 |
| Orange Fibre Channel | Each node | SAN array |
| Black power | Each node | Two PDUs |
| Each back-end switch | One PDU | |
| Each storage tray | Two PDUs |
Note:
- Nodes in HCP with SAN-attached storage systems are either individual servers or individual blades in blade servers. The figure shows individual servers.
- Some HCP with SAN-attached storage systems include Fibre Channel switches between the nodes and the SAN arrays.
