SCO OpenServer 6

The SCO Group/www.sco.com/, Inc. ("SCO") (Nasdaq: SCOX), the owner of the UNIX(R) operating system and a leading provider of UNIX-based solutions, today announced the shipment of SCO OpenServer(TM) 6, a multi-year, multi-million dollar development effort that has produced a significant upgrade to SCO's flagship UNIX operating system. SCO OpenServer 6 has been designed to provide customers with increased productivity, greater security, more agility through Open Source technologies and protection of customers' investments by providing backward compatibility with existing applications.

In developing SCO OpenServer 6 the design team included the UNIX System V Release 5 (SVR5) technology that has been proven in SCO UnixWare(R) 7. SCO has successfully integrated SVR5 into SCO OpenServer 6, which now provides customers with a significant increase in performance and a greater choice of applications that run on both UnixWare 7 and SCO OpenServer. Software vendors benefit by developing and certifying applications once that run on both UNIX operating systems, saving significant time and development resources without having to recompile applications.

In addition to significantly increased performance, in some cases two to four times the performance of the previous version, SCO OpenServer 6 customers will gain greater capabilities in the number of supported processors, increased memory and large file size support. These include:

Multi-Threaded Application Support - SCO OpenServer 6 supports multi- threaded applications with native SVR5 kernel support, which increases the overall response and performance of applications. The pre-emptive SVR5 kernel supports multi-threading for C, C++, and Java applications through the POSIX interface.

Large File Size Support - SCO OpenServer 6 supports file sizes up to 1 TB, for both disk-based and network files. File systems can grow as large as 1 TB, and larger network files are supported through Network File System (NFS) v3.

Multi-Processor Support - SCO OpenServer 6 now supports up to 32 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.

SCO OpenServer 6 builds upon its heritage as one of the most secure and reliable operating systems available with the addition of several security enhancements including SSH for remotely logging onto systems using encryption, IP firewall filter for regulating IP traffic and IPsec for virtual private networking. Encrypted file and file system capabilities are also included.
