Analysis of 64-bit technology application of the operating system

You know, only the choice of 64-bit server operating system and application Server software, 64-bit server to achieve a very good popularity and application, 64-bit server to "truly".

The current tripod of Unix, Windows server, and Linux on 64-bit network operating systems has become increasingly apparent. While Unix has a leading position in enterprise-class high-end applications, the introduction of Windows Server 2003 and the update of the Linux 2.6 kernel pose a threat to the UNIX market that cannot be constantly updated to address this pressure.

In large enterprises, the cost of fully deploying Linux or transferring from Windows to Linux is 3~4 times higher than upgrading windows to a new version, requiring 3 times times longer. Compared to UNIX and Windows, Linux can significantly improve TCO by deploying small businesses with customized vertical applications or a new networked environment.

To be a key business application platform, reliability and stability are the primary goals that users expect to achieve, and the system that is not at all is likely to be favored by users. In this regard, UNIX has a unique advantage, of course, Windows Server 2003 and the new version of the Linux kernel has greatly improved the reliability of the operating system.

Microsoft is in the realm of client operating system with ease of use, at the same time, it has the advantage of the network operating system, UNIX and Linux has been at a disadvantage, but the effort towards ease of use has made it a little improvement, especially the lack of technical power users need to consider this issue.

Good integration will benefit both developers and administrators, and currently Windows and UNIX are well integrated with their development environment and management tools, and Linux needs to be strengthened in this regard, and the better development environment and management tools that are integrated with it need to be perfected. The popularization degree of the network operating system is closely related to the development of the relevant application on the platform and the types of application software. There are quite a few types of applications on UNIX and Windows platforms, and the number of applications on Linux platforms is far worse due to some limitations on Linux platforms.

One, 64-bit UNIX operating system

While the 64-bit UNIX operating system has fallen in market share over the past two years, Unix's high-end advantage still exists. In particular, UNIX operating system software is constantly changing with the upgrade of the server hardware provided by the vendors, and it is closely combined with hardware to enable it to have proven scalability, reliability and manageability, making Unix the choice for many enterprises to create key business IT infrastructures. Technologies such as grids, dynamic partitioning, and self-management capabilities are also being integrated into a new generation of UNIX operating systems. One thing to emphasize is that while UNIX is always known as an open system, in fact the product compatibility between IBM, HP and Sun's three vendors is not good, and is limited by the corresponding server hardware. Of course, this openness continues to improve. The UNIX operating system is no longer just running its own hardware platform, starting to support a variety of hardware platforms. Sun Solaris supports not only the server hardware of SPARC chips, but also the products of the x86 architecture. HP-UX also extends from high-end servers to Itanium server platforms. The interactive nature of three UNIX operating systems and Linux shows an open trend.

1, IBM AIX 5L

The 64-bit AIX 5L release has been around for two years, and the OS version has changed with the growth of IBM P-series servers. AIX 5L increases the computational speed of bandwidth-intensive workloads and is more applicable to enterprise-critical applications. Enhanced dynamic partitioning by introducing dynamic logical partitioning (DLPAR) into the AIX 5L V5.2, IBM provides advanced flexibility and scalability for the Power chip P-series systems. The Dlpar feature makes it possible to run multiple stand-alone operating system images of Aix 5L and Linux on a single P-series server. Logical partitions do not need to conform to the physical boundaries of the system's build modules (resource collections). Dlpar allows customers to select components from the entire pool of available resources with a smaller granularity, which can increase the flexibility of the operation.

The affinity between Linux affinity Aix 5L and Linux can help achieve a multi-platform integration solution across AIX and Linux platforms in a faster, cheaper way. For many applications that are developed on Linux or developed for Linux, simply recompile the source code and they can run on the Aix 5L. Support Grid IBM Aix adds a toolbox for grid applications based on the Globus Open source protocol. IBM's free installation of this toolbox is a middleware that allows users to share supercomputing capabilities, data, and applications as easily as they can get information on the WEB. It connects many heterogeneous servers into a huge computer system. With this software, application developers are also able to create new grid based applications.

2, Sun Solaris 10

The 64-bit Solaris 10, which Sun will launch in the third quarter of 2004, will be a major upgrade to its UNIX OS. The new feature includes a technique called N1 Grid containers. With the help of this technology, users can divide the server into multiple partitions. For applications, these partitions are like many different machines, but actually only use a single Solaris instance.

Other new features of the Solaris 10 upgrade include dtrace and predictive self healing (predictive self-healing). DTrace is a diagnostic technique for determining the cause of a performance problem. Predictive Self Healing Studies the behavior of the server, predicting where the failure might occur and making up for it. As one of the innovative new technologies used in Solaris 10, Dtrace is built inside the Solaris OS and employs 25,000 probes in the kernel, which is a joy to developers, system administrators, and IT managers. DTrace is a dynamic tracking framework that performs real-time troubleshooting of the network and adjusts the performance of the system.

It looks at the entire Solaris OS system in a completely new way, discovers previously hidden system problems, and fixes performance problems that were not resolved in the past. With Dtrace, you can examine user programs and the behavior of the Solaris OS, quickly identify the underlying causes of system and application bottlenecks, highlight trends and patterns of system throttling to achieve optimal performance, capture performance issues between different levels of software, and identify the causes of abnormal behavior; Write reusable scripts for ordinary or complex routines, specify the data that Dtrace collects, the actions taken, and the conditions under which these actions are taken.

3. HP-UX 11i

The 64-bit HP-UX 11i provides a powerful driver for managing enterprise mission-critical servers based on Pa-risc and Itanium platforms, and is a secure commercial UNIX infrastructure for growing businesses. HP-UX 11i has innovative server virtualization capabilities, including zoning capabilities and leading workload management and high availability, leveraging system resources while maintaining service levels. The IT environment virtualization capabilities built into HP-UX 11i enable the customer's infrastructure to adapt, evolve, and respond to changes in their business needs and workloads. HP still considers HP-UX to be a proven, business-critical operating system.

HP's unix-based HP-UX 11i v2, developed for Intel Itanium processors, is functionally equivalent to HP-UX versions developed for its proprietary PA-RISC processor, in addition to the Itanium binary compatibility and a complete set of workload management tools. As a result, users can easily create seamless and interoperable heterogeneous environments. Developers supporting the HP-UX 11i V2 include major independent software vendors that provide a wide range of tools and applications for the HP-UX 11i V2 operating system. HP-UX 11i, which runs on the Intel Itanium processor family, can transparently execute pa-risc binaries without recompiling.
