Appliance Cluster Configuration
Appliance Cluster Configuration
The Oracle ZFS Storage Appliance supports cooperative clustering of appliances. This strategy
can be part of an integrated approach to availability enhancement that may also include client-
side load balancing, proper site planning, proactive and reactive maintenance and repair, and the
single-appliance hardware redundancy built into all Oracle ZFS Storage Appliances.
Note - If you are configuring clustering for two new controllers, follow the procedure
“Configuring the Appliance for the First Time” in Oracle ZFS Storage Appliance Installation
Guide.
