"If you're looking for good news on the clustering front, you'll find it in several areas. Scientific cluster computing ala Beowulf continues to grow and bring out products from old and new hardware vendors alike. Protocol clusters are finally emerging on the commercial front from vendors such as TurboLinux and Resonate. And other serious server management tools such as Tivoli Enterprise Management and Computer Associates's Unicenter are starting to appear on the horizon as well.
But the best cluster product on the show floor at the recent LinuxWorld Conference & Expo wasn't a Linux system at all. ... This was the Compaq Tru64 Unix cluster system, formerly Digital Unix clustering. ...Tru64 sets the standard that Linux and other vendors should aim to meet, despite the long hard road it will take to get there."
"Clustering enables scalability. Symetric multiprocessing systems scale by adding more processors, higher speed buses, and increased memory, which significantly increases the complexity and price of the system. Clusters, on the other hand, use standard off-the-shelf components to build systems that are incrementally faster. And they do so without the significant additional expense of SMP systems..."
"parallel-computing clusters like Beowulf have a limited appeal to businesses when compared to the much simpler solution offered by failover clustering -- which is already available with Compaq Tru64 clusters, Novell InterNetWare, and Microsoft Cluster Server."
