New White Paper: Practicing Solaris Cluster using VirtualBox

For developers it is often convenient to have all tools necessary for their work in one place, ideally on a laptop for maximum mobility.

For system administrators, it is often critical to have a test system on which to try out things and learn about new features. Of course the system needs to be low cost and transportable to anywhere they need to be.

HA Clusters are often perceived as complex to setup and resource hungry in terms of hardware requirements.

This white paper explains how to setup a single x86 based system (like a laptop) with OpenSolaris, configuring a training and development environment for Solaris 10 / Solaris Cluster 3.2 and using VirtualBox to setup a two node cluster. The configuration can then be used to practice various technologies:

OpenSolaris technologies like Crossbow (to create virtual networking adapters), COMSTAR (to export iSCSI targets from the host being used as iSCSI initiators by the Solaris Cluster nodes as shared storage and quorum device), ZFS (to  export a ZFS volume as iSCSI targets and as failover file system within the cluster) and IPsec (to secure the cluster private interconnect traffic) are used for the host system and VirtualBox guests to configure Solaris 10 / Solaris Cluster 3.2.

Solaris Cluster technologies like software quorum and zone clusters are getting used to setup HA MySQL and HA Tomcat as failover services running in one virtual cluster. A second virtual cluster is being used to show how to setup Apache as a scalable service.

The instructions can be used as a step-by-step guide to setup any x86 64bit based system that is capable to run OpenSolaris. A CPU which supports hardware virtualization is recommended as well as at least 3GB of main memory. In order to try out if your system works, simply boot the OpenSolaris live CD-ROM and confirm with the Device Driver Utility (DDU) that all required components are able to run. The hardware compatibility list can be found at http://www.sun.com/bigadmin/hcl/. The role model for such a system is the Toshiba Tecra M10 with 4GB main memory.

If you ever had missed a possibility to just try out things with Solaris 10 and Solaris Cluster 3.2 and exploring new features - this is your chance :-)

Some Blueprints and Whitepaper for Solaris Cluster

Recently there have been some Blueprints and Whitepaper made available, which also cover Solaris Cluster within the various topics:

  1. Blueprint: Deploying MySQL Database in Solaris Cluster Environments for Increased High Availability
  2. Whitepaper: High Availability in the Datacenter with the Sun SPARC Enterprise Server Line
  3. Community-Submitted Article on BigAdmin: Installing HA Containers With ZFS Using the Solaris 10 5/08 OS and Solaris Cluster 3.2 Software
Hope you find them useful!
