4-2 Compaq Parallel Database Cluster Model PDC/O5000 for Oracle8i and Windows 2000 Administrator Guide Site Planning You must carefully select and prepare the site to ensure a smooth installation and a safe and efficient work environment. To select and prepare a location for your cluster, consider the following: I The path from the receiving dock to the installation area I Availability of appropriate equipment and qualified personnel I Space for unpacking, installing, and servicing the computer equipment I Sufficient floor strength for the computer equipment I Cabling requirements, including the placement of network and Fibre Channel cables within one room (under the subfloor, on the floor, or overhead) and possibly between rooms I Client LAN resource planning, including the number of hubs or switches and cables to connect to the cluster nodes I Environmental conditions, including temperature, humidity, and air quality I Power, including voltage, current, grounding, noise, outlet type, and equipment proximity IMPORTANT: Carefully review the power requirements for your cluster components to identify special electrical supply needs in advance. Capacity Planning for Cluster Hardware Compaq ProLiant Servers The number of servers you install in a PDC/O5000 should take into account the levels of availability and scalability your site requires. Start by planning your cluster so that the failure of a single node will not adversely impact cluster operations. For example, when running a two-node cluster, the failure of one node leaves the one remaining node to service all clients. This could result in an unacceptable level of performance.
