Axigen Integration with Veritas Cluster Server 5.0

Around two years ago the Axigen Mail Server began the Cluster Support Era with the final touches being added to the SMTP, POP3, IMAP and Webmail proxy services. Back in the day, our main concern was the Red Hat Clustering Suite included in the RHEL5 Linux distribution, developed and maintained by Red Hat, because it was (and still is) one of the most widespread clustering solutions, and also has a free of charge alternative built into CentOS.
However, now that the product has evolved and the product’s exposure to the market has grown considerably, a variety of clustering alternatives have to be supported to meet the demands and requirements of our customers. The year 2009 was very productive from the clustering integration standpoint, as the team had amassed quite a lot of knowledge of incalculable value.

The Veritas Cluster Server version 5.0

Few are the experts in the IT&C industry that have not heard of the Symantec Veritas Cluster suite. It is one of the most advanced and reliable solutions on the market, partly because it has a lot of history behind it. Like most mature products, it has been polished to a great extent and the usability of the product is much higher than its younger counterparts. Nevertheless, for anyone that has not had any contact with the VCS suite before, the shocking ease of use and degree of automation embedded in the product will be a very pleasant surprise.
Like most failover cluster packages, Veritas uses the basic building blocks of the “movable system services”. The cluster is made up of a bunch of systems, called nodes, some resources (like storage devices, IPs, shares and service instances), some zones and some rules by which service migration from one computer to another is governed.

Normally, the cluster installation should take some time, even for the more experienced users that do the preparation phase flawlessly. I was pleasantly surprised to find out that it is not the case with VCS5. Within a little under one hour, the entire cluster had been installed and ready to go, on my four cluster nodes, leaving me with the only the task of configuring it. The installation itself is pretty seamless, as the automatic installation wizard does its job without generating issues.

Another feature of the installer I also enjoy is the environment pre-check process that enables you to see whether you overlooked any details during your cluster preparation phase. This feature is also available in the Windows 2003 and 2008 failover cluster suite and is a welcome addition anytime; RHCS, however, is missing this functionality.
