SCO OpenServer Release 6 represents the start of a new era for UNIX systems. UNIX has proven itself as an Internet server standard, delivering the open infrastructure that has helped to make the Internet permeative. The UNIX operating system is a mature, reliable, scalable, high-performance platform for running business-critical applications. The SCO Group Inc. announced that SCO OpenServer 6, the next major release of SCO’s flagship UNIX operating system, has entered formal beta testing and is expected to begin shipping in May. The product, developed under the code-name Legend, has been part of a multi-year, multi-million dollar development effort. 

• Symmetrical Multi-Processing – SCO OpenServer 6 now supports up to 16 processors.
• Increased Memory Support – General applications running on SCO OpenServer 6 can utilize up to 16 GB of general-purpose memory, while additional memory can be dedicated for special applications, allowing databases to access up to 64 GB of memory. 
• Increased File Size Support – SCO OpenServer 6 supports file sizes larger than 2 GB, for both disk-based and network files. Disk based file systems can grow as large as 1 TB, and larger network files are supported through Network File System (NFS) v3. 
• Multi-Threaded Application Support – SCO OpenServer 6 supports multi-threaded applications with native UNIX System V kernel support, which increases the overall response and performance of applications. The UNIX kernel is fully pre-emptive, and supports multi-threading for C, C++, and Java applications through the POSIX interface. 
• System Analysis and Performance Monitoring Tools – SCO OpenServer Release 6 also provides the real-time performance monitor (rtpm), an interactive and screen-based utility that provides real-time display of performance metrics. You can also log system activity for capacity planning or performance analysis.
