New white paper available: Providing High Availability to the OpenStack Cloud Controller on Oracle Solaris with Oracle Solaris Cluster
By T.F.-Oracle on May 17, 2015
Oracle Solaris delivers a complete OpenStack distribution which is integrated with its core technologies such as Oracle Solaris Zones, the ZFS file system, and its image packaging system (IPS). OpenStack in Oracle Solaris 11.2 helps IT organizations to create an enterprise-ready Infrastructure as a Service (IaaS) cloud, so that users can quickly deploy virtual networking and compute resources by using a centralized web-based portal.
Of course any enterprise-class OpenStack deployment requires a highly available OpenStack infrastructure that can sustain individual system failures.
Oracle Solaris Cluster is deeply integrated with Oracle Solaris technologies and delivers high availability to Oracle Solaris based OpenStack services through a rich set of features.
The primary goals of the Oracle Solaris Cluster software are to maximize service availability through fine-grained monitoring and automated recovery of critical services and to prevent data corruption through proper fencing. The services covered include networking, storage, virtualization used by the OpenStack cloud controller and its own components.
Our team has created a new white paper to specifically explain how to provide high availability to the OpenStack cloud controller on Oracle Solaris with Oracle Solaris Cluster.
After describing an example for a highly available physical node OpenStack infrastructure deployment, a detailed and structured walk-through over the high availability cloud controller configuration is provided. It discusses each OpenStack component that runs on the cloud controller, with explicit steps on how to create and configure these components under cluster control. The deployment example achieves secure isolation between services, while defining all the required dependencies for proper startup and stopping between services which is orchestrated by the cluster framework.

Another new feature of Oracle Solaris Cluster Geographic Edition
A few weeks ago I wrote about a new feature for Geographic Edition: DR Orchestration, which we added in Oracle Solaris Cluster 4.2. With the latest update to 4.2, SRU1, we've completed the testing of another Geographic Edition feature which can make DR Orchestration even more useful - we can now support Oracle Data Guard replication control for a remote database.
As I described before, a multigroup can combine several protection groups so that they can be switched together in a coordinated manner. That enables a service constructed out of multiple tiers, on multiple clusters, to be managed as a unit.
Since each tier is represented by a protection group it might seem necessary that each tier be running Oracle Solaris Cluster, which could be inconvenient if one of the tiers is running only an Oracle RAC database. There is no absolute requirement to use Oracle Solaris Cluster in that configuration; the systems might not be running any cluster software, or perhaps running Oracle RAC Clusterware. An example of such a configuration is the Oracle SuperCluster Engineered System.
In practice, however, we can use some features of Oracle Solaris Cluster and the Oracle Database to include such a tier in an orchestrated Geographic Edition configuration. The two features we're using are:
- The Oracle Solaris Cluster data service for Oracle External Proxy (HA for Oracle External Proxy)
- Remote database connectivity
HA for Oracle External Proxy
This is a data service which can be used to reflect the status of an Oracle database which is running on a remote system, so that local Oracle Solaris Cluster resources and resource groups can associate dependencies with it. You can find more information about it at: http://docs.oracle.com/cd/E39579_01/html/E52343/index.html
Remote Database Connectivity
This is a standard feature of the Oracle Database. A service name that is configured in the TNSNAMES.ORA file can identify a database that is running on a remote system, so that control operations from local sqlplus and dgmgrl (Data Guard broker) commands will operate on the remote database instance. To take advantage of this you don't even need to install a full Oracle database locally, you can just install the Oracle Database Client software, see: http://docs.oracle.com/database/121/SSCLI/toc.htm
Put these together, and...
By using these two features together you can now create a local Geographic Edition protection group (PG) that uses Oracle Data Guard replication, but which manages a database instance on a remote system. You just need to provide the name of a resource group that contains an external proxy resource, instead of an Oracle RAC or failover database resource. As far as the cluster configuration is concerned, this behaves just like an ordinary local protection group, and so it can be included in a multigroup as part of a DR Orchestration configuration. When you switch over that multigroup, the software will contact all the systems configured in the protection group, local and remote.
Now you can fully orchestrate all tiers of a service and control them from a system that is part of an Oracle Solaris Cluster configuration, even if the database tier is on a system that isn't running Oracle Solaris Cluster.
