New Features and Benefits



Multi-Threaded Kernel

By incorporating SVR5 technology into OpenServer Release 6, this kernel now has support for more modern applications.

Large File Support

OpenServer Release 6 includes large file support (up to 1 Terabyte) that enables it to drive more modern and powerful applications.

Multi-Processor Support

OpenServer 6 has increased multi-processor support from 4 to 32 processors, taking advantage of the power of more modern and up-to-date hardware. SVR5 is a hardened kernel that runs on low cost, industry standard servers and is capable of near-linear scaling as resources are added to the system.

Increased Memory Support

Memory support increases from 4 GB to 64 GB in OpenServer 6. This enables the product to run and support more powerful applications and hardware.

Speed and Performance

The SVR5 kernel enhancements in OpenServer 6 have produced significant improvements in speed and performance. Some OpenServer applications are reporting a 400% speed improvement with version 6.

Improved support for Asynchronous I/0

AIO enables even a single application thread to overlap disk read/write operations with other processing, thereby allowing useful work to be done while I/O is occurring in the background.

Dynamic Loadable Drivers

Drivers can be loaded or unloaded on a running system with no reboot required. This allows hot-plug of new peripherals such as a tape drive.

Includes KDE

With the addition of KDE, OpenServer 6 now has a modern, full-featured desktop, enabling a greater ease of use.

Hot-Plug Memory Support

With OpenServer 6 additional memory can be added into the system without a system reboot.

Fibre Channel-based SAN Support

OpenServer 6 comes with Fibrechannel-based SAN support for HP MSA 1000 systems. Xinuos supports QLogic Fibre Channel 22xx/23xx controllers.

VXFS Filesystem

High performance VXFS filesystem is journaled, ensuring data integrity in case of a hardware crash.

Hardware RAID Support

OpenServer 6 supports the following RAID systems: Adaptec hardware RAID controllers, HP/Compaq RAID controllers, Intel Integrated RAID, LSI MegaRAID, and LSI Fusion-MPT RAID.

USB Printer Support

OpenServer 6 supports USB printers.

DVD Backup Support

With OpenServer 6, businesses can utilize DVD backup systems, enabling faster and more cost effective backup of valuable data.

Supports UnixWare® 7.1.4 Applications

With the SVR5 kernel technology embedded in OpenServer 6, UnixWare applications are fully supported.

Serial Attached SCSI (SAS) for HP Proliant Products

SAS is the next generation of host controllers, and will replace slower parallel technologies, as well as control for the first time both Serial ATA and Serial Attached SCSI hard drives.

Native SATA

OpenServer 6 features full support for Intel's open Advanced Host Controller Interface ( AHCI) specification which includes features such as Native Command Queuing and Hot-Plug support.

Xinuos's Assessment and Migration Services

Specifically designed for OpenServer 6, these services enable customers to make the most efficient use of their IT staff. These options will also be found beneficial in implementing Xinuos solutions that optimize productivity by leveraging the new and greatly improved features of the operating system.


Encrypts all TCP/IP packets for security, and implements Virtual Private Network (VPN) functionality.

OpenSSH and OpenSSL

These network protocols allow for logging into and executing commands on a remote computer. They provide secure encrypted communications between two untrusted hosts over an insecure network.

Ipfilter for Firewall and NAT Functionality

Ipfilter technology allows OpenServer 6 to be configured as a firewall.

Kernel Privileges

The SVR5 kernel provides a fine-grain privilege mechanism. Using fine-grain privileges, the system can grant a subset of root powers to binaries, allowing them to achieve specific objectives without exposing the system to potential abuse/exploits.

Auditing of Events

Auditing enables the system administrator to record system events in a log and play back the audit trail to determine who did what and when.

Supports NFS v3 with TCP

Network File System (NFS) is an industry standard protocol for sharing files across networks. NFS v3 adds support for large files and NFS over the TCP protocol.

Encrypted File System and Archives

This file system encrypts data stored on the disk. The data can then be de-crypted using private keys.

Emergency Recovery CD-R/RW Media Support

Emergency recovery enables the system administrator to create bootable CD-R/RW media for disaster recovery.

Centrino™ Wireless Technology

Centrino is an Intel wireless technology standard supported by Xinuos. With this new technology included in OpenServer 6, laptops now have fully integrated wireless LAN capability without the need of a wireless plug-in card for excellent mobile performance.

PRISM Technology

A wireless hardware chipset standard supported by Xinuos. OpenServer 6 supports a myriad of wireless devices that are PRISM based enabling more wireless networking capabilities.

Apache version 1.3

OpenServer 6 includes the popular open source Apache web server.

Mozilla 1.7 and Java Plug-ins

Release 6 includes the 1.7 release of the popular Mozilla web browser.


Tomcat enables OpenServer 6 to run and display Java applets. Tomcat is an open source implementation of JavaServer Pages and Java Servlets. JSP and Java Servlets are the Web presentation layer in Java 2.

File and Print Server with Samba 3.013

Samba provides file and print interoperability services between UNIX and Windows clients.

MySQL Database

UNIX customers are ever increasingly looking for database alternatives. MySQL, a good and cost-effective alternative to other popular databases, is included with OpenServer 6.

Wide Hardware Support

OpenServer 6 includes support for USB, AC97, SATA, SAS, IDE RAID, FC SAN, PCIX and others.

Java 1.4.2

OpenServer 6 supports the Java 2 platform, Standard Edition for running Java code.

Supports Thousands of Applications

OpenServer 6 will run thousands of applications written for UnixWare and OpenServer.

Full Backward Compatibility, Including Xenix Application Support

Small businesses have invested considerable money in hardware. With OpenServer 6, Xinuos supports applications all the way back to Xenix 286 applications.

Technical Overview

OpenServer Release 6 is specifically designed to address the need to modernize the OpenServer operating system—with an intense focus on adding support for kernel-level threads and large files. To achieve these requirements, Xinuos has replaced the existing OpenServer kernel with the SVR5 kernel. OpenServer Release 6 also gives users the option of using the latest KDE graphical desktop or they can use the traditional OpenServer Desktop, also known as the traditional X-Windows/ CLI interface.

This kernel improvement dramatically improves the speed and performance of OpenServer. It also meets a growing customer need for larger file size support (up to 1 Terabyte) and greater memory support. This change also allows OpenServer customers to gain a broader exposure to UnixWare applications. A key element of this release for ISVs and IHVs is the ability to “single certify” on one operating system and function on both.
