Clustered Platform 280/3 Hardware Installation

This chapter contains the following topics:

• Power and Heating Requirements
• Clustered Platform Component Location
• Connectivity
• Connecting the Hardware

Power and Heating Requirements

The Clustered Platform 280/3 hardware must have two dedicated AC breakers. The cabinet should not share these breakers with other, unrelated equipment. The system requires two L30-R receptacles for the cabinet, split between two isolated circuits. For international installations, the system requires two Blue 32AIEC309 (international) receptacles.

---

Note - To eliminate any single point of failure (SPOFs), you must provide two independent primary power sources. For details on power sources and power sequencers, refer to the Sun StorEdge Expansion Cabinet Installation and Service Manual. This document is supplied to you as a printed manual.

---

If the cabinet is installed on a raised floor, cool conditioned air should be directed to the bottom of the expansion cabinet through perforated panels.

The Clustered Platform 280/3 system consumes power and dissipates heat as shown in TABLE 2-1.

Clustered Platform Component Location

FIGURE 2-1 shows how the Clustered Platform 280/3 is arranged in the expansion cabinet. The hardware components are placed in the dual-power sequenced 72-inch expansion cabinets.

System components are cabled in the expansion cabinet to provide power and connections between the hardware components.

---

Note - The expansion cabinet arrangement complies with weight distribution, cooling, electromagnetic interference (EMI), and power requirements.

Connectivity

The Clustered Database Platform 280/3 system provides maximum connectivity in your enterprise network using the following network implementations:

• Production network connectivity--You connect the cluster nodes to your main network using the Sun Fire 280R server qfe0 connectors. Network automatic failover (NAFO) is provided on separate Sun Quad FastEthernet controllers (qfe4) to avoid a single point of failure (SPOF).
• Administration network connectivity--After you connect the management server and the terminal concentrator to your administration network, the management server has the connectivity needed to give you access to the administration software (Sun Management Center, Component Manager, and SunRay server software). This network configuration isolates the administrative functions from your production network. If your environment does not have an administration network, you can connect the management server and the terminal concentrator to your production network, maintaining the same cluster platform functionality, without the network isolation.
• Internal administration network--The management server, cluster nodes, and cluster storage are connected to each other through the built-in Ethernet hub. Internal administration connections are configured at the factory. This network is referred to as the internal administration network to distinguish it from the administration network (described above).
• Cluster interconnect--The cluster connectivity between nodes uses Ethernet patch cables (no Ethernet switch required), with multiple qfe 100BASE-T ports (qfe1 and qfe5) on two separate controllers to avoid a controller SPOF.

Clustered Database Platform 280/3 System Cabling

The Clustered Database Platform 280/3 system is shipped with the servers, hubs, and each of the arrays already connected in the cabinet. You do not need to cable the internal system components. The next chapter describes how to connect the Cluster Platform to your enterprise network.

For factory configured cable connections, see Appendix A.

Connecting the Hardware

This section contains a procedure for connecting the hardware at the customer site.

To Install the Clustered Database Platform 280/3 Hardware

1. Connect the Clustered Database Platform 280/3 electrical cords to two separate power sources, but do not turn on the power to the Cluster Platform at this time.

See Power and Heating Requirements.

2. Connect the Clustered Database Platform 280/3 to your network(s) as described in the following steps and shown in FIGURE 2-3:

a. Connect the eri0 port of the management server to your administration network.

If you do not have an administration network, connect eri0 to your production network.

b. Connect the Ethernet port on the terminal concentrator to your administration network.

If you do not have an administration network, connect the Ethernet port to your production network.

c. Connect the qfe0 port on node 2 to your production network.

d. Connect the qfe4 port on node 2 to your production network.

This connection provides connectivity for network automatic failover (NAFO).

e. Connect the qfe0 port on node 1 to your production network.

f. Connect the qfe4 port on node 1 to your production network.

This connection provides connectivity for network automatic failover (NAFO).
