This section does not cover in detail the procedures for setting up Oracle ZFSSA. For more information about the appliance including configuration steps, refer to the following sources:
Oracle ZFSSA product documentation in the Oracle Help Center storage documentation page
Using the Oracle ZFS Storage Appliance as Storage Back End for OpenStack Cinder. This white paper details how to set up the storage appliance for use in the cloud.
Prior to the procedures to set up OpenStack with Oracle ZFSSA, make sure that you have already created the subnet that would host data storage traffic. The scenario in this chapter uses Figure 2 as a basis for this starting point but with a difference. Here, storage data traffic is hosted over two subnets, with net2 and net3 as the interfaces for that traffic. The two subnets ensure efficient performance and availability of the data storage service.
Oracle ZFSSA uses iSCSI for exchanging SCSI commands over the network. To set up communication between iSCSI nodes, you must have the following information available:
SCSI node DNS name or IP address. The SCSI node consists of both the initiator and target nodes.
TCP iSCSI Internet port on the target node. By default the port number is 3260.
iSCSI Qualified Names (IQNs) of both the initiator and target nodes.
Optional authentication information using Challenge Handshake Authentication Protocol (CHAP authentication)
To obtain relevant iSCSI information for this preparatory step, use the Oracle Solaris iscsiadm command.
This document does not describe the steps to configure the appliance. For procedures to prepare the appliance for operational use, refer to the appropriate release documentation in Oracle's Storage Documentation.
The OpenStack ZFSSA Cinder driver creates and manages volumes by creating the related LUNs on the appliance, setting up the appropriate properties of these LUNs, and managing the LUNs' visibility to the OpenStack compute nodes and guest instances on which the volumes are being used.
After setting up the Oracle ZFSSA, you can then configure the ZFSSA iSCSI Cinder driver.
