Site Planning

Capacity Planning for Cluster Hardware

Compaq ProLiant Servers

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.
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.
