"In May, Cobalt Networks Inc., a provider of server appliances, announced Cobalt StaQware, a high availability clustering solution that ensures the uptime of business critical Web sites and applications. StaQware, which runs on Cobalt's RaQ 3i server appliances, offers 99.99 percent availability and requires no customization or modification to applications."
"StaQware requires the user to have two RaQ 3i server appliances as the hardware platform. StaQware is available through the Cobalt Web site at shop.cobalt.com. Through the end of June, Cobalt StaQware will be available at a special introductory price of $499 - 50 percent off of the suggested retail price of $999."
"But, the ability to cluster only two systems is hardly a world-beater. TurboLinux already has a cluster solution (Ref. TurboLinux Clusters - One More Step Taken) for approximately the same price as Cobalt's (excluding Cobalt's special promo). The difference is TurboCluster has a version that can handle 25 or more nodes, vs. two for StaQware. StaQware does not load-balance, which we always thought was an intrinsic part of clustering. In addition, the "failover" requires from one to 10 minutes for the backup system to spin up the disk, etc. Maybe we're being provincial, but in our world, this is a replicated, semi-hot backup, not a cluster. Even Microsoft clusters (until recently considered an oxymoronic term by some) seem to be more cluster-like than this offering."
