Mission Critical Linux Shoots for the Enterprise

Mission Critical Linux Inc. has launched server-clustering software for enterprise environments that need high-availability and downtime protection.

Dubbed Convolo Cluster, the software allows two servers to be clustered in a configuration where both servers are actively operating. Convolo Cluster is platform-independent and will operate on Intel, SPARC, Alpha or MIPS servers.

A Compaq Computer Corp. engineer, Moiz Kohari, founded Mission Critical Linux in July 1999. The company has 80 employees and is venture-backed with $US20 million by General Atlantic Partners. Its headquarters are in Massachusetts.

Convolo Cluster ships with 60-days of remote, proactive monitoring and includes crash analysis tools that monitor clustered servers, looking for possible problems. The Convolo Cluster can operate on systems running Red Hat Inc., TurboLinux Inc., VA Linux Systems Inc., SuSE Linux AG, Caldera Systems Inc., MandrakeSoft Inc. or Software in the Public Interest Inc.'s Debian Linux.

The clustering software supports a shared disk configuration using either SCSI or Fibre Channel, and servers can be connected to each other via Ethernet, serial line, SCSI or Fibre Channel.

Convolo Cluster uses Mission Critical's Kimberlite clustering technology, which the company released under GNU General Public License earlier this month. The source code can be downloaded from Mission Critical's site.

Kimberlite clustering provides the ability to detect when either node leaves the cluster and automatically trigger scripts that perform the tasks necessary to restart applications on the remaining node. When the server is fixed and rejoins the cluster, applications can be automatically or manually moved back to it.

Convolo Cluster is $US1,000 per server and is available this month. Service after the 60-day free period starts at $US10,000 per server per year.
