Stratus is shipping Red Hat Enterprise Linux 4 on its Intel-based fault tolerant servers. The company's ftServer T30 and T60 servers, two-way and two or four-way systems respectively, now support Red Hat-certified applications. Previously, the company shipped only its own Linux, which is based on the 2.4 kernel.

Stratus hopes to capitalise on the growing importance of Linux and its use for mission-critical apps. According to a recent IDC report, the Linux will grow by 63 percent in the next two years in the high-availability (HA) market. In contrast, the overall HA server market will increase by under 15 percent.

The ftServer T30 is aimed at telcos as well as non-IT related enterprises. Stratus claims that "virtually any application for the Linux operating environment will run unchanged and unmodified".

Senior vice president Greg Enriquez said: "Mission-critical Linux is only possible when the underlying hardware platform is unrelentingly reliable, and that's a combination the marketplace has been demanding. Our first branded Linux based on the Red Hat distribution, coupled with the field-proven performance of our ftServer platform, makes this the right place and the right time for the T60 system, especially for IT managers who may be planning to run 20 or more virtual servers on a single box."

According to Stratus, the servers' advantage lies in the T Series' replicated, fault-tolerant hardware that eliminates single points of failure and protects data integrity. The result is better uptime and greater simplification.

Positioning the company's products against clusters, the company said: "Hardware-based fault tolerance requires no failover scripting, repeated test procedures, or application modification to ensure applications availability or smooth integration of systems into the IT or network infrastructure. Open, portable Linux applications can now run unchanged and unmodified on carrier-grade, continuously available servers."
