2-32 Compaq ProLiant Clusters HA/F100 and HA/F200 Administrator Guide Load Balancing Load balancing helps to attain enhanced performance from the cluster by balancing the system's workload. With cluster configurations, applications and data can be shared by all components so that no one component is working at its maximum capability. There are two means of load balancing. One way balances a system's workload across the cluster. The other balances a server's workload across multiple data paths. The dual redundant loop of the Compaq ProLiant Cluster HA/F200 and an added RA4000 storage system spread a system's applications and data across the data paths through an active/active host bus adapter. This configuration can increase the functionality of the cluster. IMPORTANT: Disk load balancing cannot be done when using a single RA4000 in a Compaq ProLiant Cluster HA/F200. Add another RA4000 to your HA/F200 configuration for host bus adapters in a single server to be active/active. Figure 2-17 shows a Compaq ProLiant Cluster HA/F200 configuration with only one RA4000. Because there is only one RA4000, the host bus adapters are in active/standby mode, which means that they do not have load-balancing capability.

Compaq ProLiant Clusters HA/F100 and HA/F200 Administrator Guide
Load Balancing
Load balancing helps to attain enhanced performance from the cluster by
balancing the system’s workload. With cluster configurations, applications and
data can be shared by all components so that no one component is working at
its maximum capability.
There are two means of load balancing. One way balances a system’s
workload across the cluster. The other balances a server’s workload across
multiple data paths. The dual redundant loop of the Compaq ProLiant
Cluster HA/F200 and an added RA4000 storage system spread a system’s
applications and data across the data paths through an active/active host bus
adapter. This configuration can increase the functionality of the cluster.
IMPORTANT:
Disk load balancing cannot be done when using a single RA4000 in a
Compaq ProLiant Cluster HA/F200. Add another RA4000 to your HA/F200 configuration for
host bus adapters in a single server to be active/active.
Figure 2-17 shows a Compaq ProLiant Cluster HA/F200 configuration with
only one RA4000. Because there is only one RA4000, the host bus adapters
are in active/standby mode, which means that they do not have load-balancing
capability.
