PCA Fiber Channel Support for External Storage
(Doc ID 1985109.1)
Last updated on JULY 14, 2020
Applies to:Private Cloud Appliance - Version 2.0.1 and later
Oracle PCA introduces the concept of "storage clouds" that group together the FC ports used to connect the Fabric Interconnects to your own FC switch or switches. Two FC ports on each of the Fabric Interconnects are assigned to a cloud. A vHBA is created on each server for each storage cloud. A total of four storage clouds are defined when the Oracle PCA is provisioned, resulting in four vHBAs on each of the compute and management nodes.
Storage clouds allow you to cable and configure your external storage in such a way as to improve overall throughput or to build a fully HA enabled infrastructure. The storage clouds are created and configured automatically, so that all you need to do is choose the type of HA configuration that you wish to use and then cable accordingly. The design of the storage cloud configuration reduces complexity in configuration and allows the greatest possible flexibility in terms of your HA requirements.
In order to use external FC storage with your Oracle PCA, you need to be running version 2.0.1 of the Oracle PCA software. Earlier versions do not support storage clouds or FC storage. Users intending to configure external FC storage should be familiar with how to operate their VCA, how to configure and administer the storage they are intending to use with PCA, and should have an understanding of how to configure and zone FC switches and FC fabrics.
