Stratus Technologies, which specialises in high availability server platforms, is adding 64-bit Linux to all its enterprise-level high availability server models, previously available only with Windows.
Based on Red Hat Enterprise Linux AS 4, the systems use EM64T to support both 32-bit and 64-bit applications. Enterprises buying ftServer 2400, 4300, or 5700 (Dual Core) server models can now choose either RHEL 64-bit or Windows Server 2003, with no price differential. Alternatively, Stratus said customers can install the OS under their own master licence or subscription service agreements.
The company noted that its mid-range ftServer 4600 system is being phased out of production from September 2006.
All systems are available now and comply with the European Union's Reduction of Hazardous Substances (RoHS) directives, according to the company.
According to Stratus, demand for Linux servers is expected to lead the high-availability server market with a 37.7 percent compounded annual growth rate (CAGR) through 2009, according to market researcher IDC. The high-availability server market overall and the Windows server segment are expected to grow 14.4 percent and 27.5 percent, respectively, during the same period.
The fault-tolerant technology that enables a claimed 99.999-plus percent availability on Intel-based ftServer lines resides in Stratus-designed chipsets and in the company's system software layer that sits between the OS kernel and the application. Virtually any application for the Linux operating environment will run unchanged and unmodified on a supported Stratus fault-tolerant server, according to Stratus.
"Adoption of Linux applications throughout the IT infrastructure is inevitable and progressing quickly," said Stratus senior VP Greg Enriquez. "Providing IT management with the option of a continuously available ftServer platform, with its superior uptime reliability to support critical applications, has tremendous value."
