Power Distribution
To ensure high availability, it is recommended that the power source be configured in a way such that there
should not be power loss to 50% or more of nodes in the cluster, including the quorum server.
Implementing the recommended power configuration will improve the availability of the cluster. In many
cases failure of a server or storage component can be prevented due to loss of AC power. This prevents
Package Failover and restart or storage re-mirroring. This section can also be used as a guideline in case
the recommendations cannot be followed.
Local Regulations
• Local codes and regulations that relate to power must be followed, even if they differ from these
recommendations.
Redundant Power Supplies
•
Most servers and storage equipment have optional redundant power supplies. These should be used
and configured as described below.
Site power circuits
•
It is recommended that the cluster use two or three power circuits. This will prevent loss of one circuit
from impacting more than 50% of the nodes of the cluster.
