Infobrief Red Hat Linux 9 Professional Key Points

0. 
   Red Hat® Linux® 9 Professional is Red Hat’s consumer operating system that may be used by small businesses for web infrastructure and for desktop installations. Many of the feature enhancements from the previous version are designed to assist small businesses set up their network infrastructure or desktops.
   
1. 
   Linux provides a cost-effective, optimal operating environment for an Internet infrastructure using Dell™ PowerEdge™ servers. There are no license fees, subscriptions or per seat fees associated with the consumer version of Red Hat Linux, which is an important contribution to help lower TCO.
   
2. 
   Enterprise deployments are best served by Red Hat’s Enterprise product family product. Enterprise products offer a much higher level of support than Red Hat Linux 9 Professional. Please see the Service and Support section for further detail.
   
3. 
   Red Hat Linux 9 Professional is the LAST version of the Consumer family of operating systems that is available for system vendors such as Dell to offer with a platform, either pre-loaded or included in the system packaging. It is strongly recommended that users of Red Hat Professional in server environments begin the planning process for migrating to Red Hat’s Enterprise family of products.
   
4. 
   Red Hat no longer offers certification for the ‘Consumer’ family of products. While every effort has been taken by Dell to insure correct operation of the software on our hardware, formal certification is not available.
   
5. 
   Red Hat Linux 9 Professional has several configuration restrictions that have not existed in previous versions. Please see the Product Restrictions section for detail.
   

Linux has come a long way since August 1991, when Linus Torvalds began building an operating system (OS) that eventually became Linux, a full-featured OS that has evolved as a project of programmers worldwide.

Linux is similar to but not identical to UNIX. It runs on a wide variety of hardware, including systems based on Intel, Alpha, PowerPC and other processors. Because of the similarity between UNIX and Linux, many organizations are considering a migration from their expensive proprietary RISC systems to the combination of Intel hardware platforms from Dell and Linux from Red Hat.

The Linux operating system was developed under the GNU General Public License (GPL), making the source code freely distributable. Freely distributable means that the source code for the kernel (the core technology within any operating system) and most software cannot be withheld.

Although Linux initially referred strictly to the kernel, it now also includes a collection of configured software that runs on top of the Linux kernel. These “collections of software” are known as distributions. Currently, a number of vendors, including Red Hat and SuSE, offer distributions of Linux that include various enhancements as well as service and support.

Dell has chosen Red Hat as a strategic partner and distributes Red Hat’s versions of Linux. Red Hat maintains a strictly open source policy for its Linux offerings, which is consistent with Dell’s commitment to industry standards. Through this partnership, Dell provides customers with Red Hat Linux factory-installed on PowerEdge and PowerEdge SC servers. Red Hat Linux 9 Professional is supported by all currently shipping (as of May 2003) PowerEdge NICs, SCSI RAID controllers, and SCSI storage systems offered by Dell.

Red Hat Linux 9 Professional is an implementation of the Linux 2.4.20 kernel and distribution of the latest set of Linux utilities provided by the open source community. Dell PowerEdge servers running Red Hat Linux offer tools such as: network configuration tools, Red Hat Network for OS change management, user management tools, and hardware viewing tools. These features are elements of the operating system and come ready to use with each factory-installed Red Hat Linux-based server from Dell.

   Apache 2.0 Web Server
   The Apache Project is a collaborative software development effort aimed at creating a freely available source code implementation of an HTTP (Web) server. Apache Web Server software is widely used by Web server domains. The Apache server is well suited for e-commerce applications, where security and stability are key system requirements.
   
1. 
   Red Hat TUX Web Server
   TUX is a kernel-based web server licensed under the GNU General Public License (GPL). The TUX Web server serves static web pages, and can do so very efficiently from within the Linux kernel. The TUX Web Server is ideal for development environments, where performance and system response are critical.

    Product Upgrades
    
12. 
    Existing customers of Red Hat Professional should upgrade their software via the Red Hat Network software version control and management service. All copies of Red Hat Linux Professional come with a 180-day trial service and Dell customers are encouraged to subscribe to this service to gain access to new versions of Red Hat’s software. Dell will not be offering customer kits to upgrade software to version 9.
    

• 
  OS instabilities were observed on platforms with 6GB or 8GB of memory. While other memory configurations up to the maximum of 16GB appear to work correctly, Dell does not recommend installing on systems with greater than 4GB of RAM. Dell will not preload Red Hat Linux 9 on systems greater than 4GB.
  

• 
  Dell Power Edge 4600 systems may erroneously indicate a hardware error on the front panel during the boot sequence. This error does not indicate a hardware problem. Dell will install an updated Adaptec driver on those systems. Other PowerEdge 4600 users may obtain a copy of the boot disk by downloading the disk from Dell’s web site.
  

The release of Red Hat Linux 9 Professional is a “community product.” The term “community product” means that while as much support as possible is offered for its deployment, the Linux community is ultimately responsible for the highest level of product support. Dell and Red Hat will jointly make best efforts to resolve issues raised by supported customers unless a modification to the operating system source code is required. If such a determination is arrived at, support will be passed over to the Linux community for resolution. Customers requiring higher levels of support in a specific time period should use the Red Hat Enterprise family of products that are fully supported.

Customers requiring higher levels of support in a specific time period should use the Red Hat Linux Enterprise family of products that are fully supported.

Premier Enterprise Support

Other services are focused on rapid resolution to quickly resolve any issues as they occur. Services range from on-site¹ service for hardware to remote software and storage support with seamless support for select third party products. Gold and Platinum customers benefit from engineer-to-engineer support, on-site troubleshooting, on-site engineers, and on-site spares (depending on the options customers chose).

Some customers may require software support services on an incident package basis specifically to support their Dell | Red Hat environment. For these customers, Dell Services provides the DirectLine Plus incident packs. DirectLine Plus incident packages are sold in increments of

• 
  1 to 10 resolutions in any 1 year period
  
• 
  15 Resolutions over 3 years
  
• 
  30 Resolutions over 3 years
  

Dell provides software technical support via telephone free of charge for 30 days to customers who purchase Red Hat Linux 9 Professional factory installed on PowerEdge and SC Servers. If customers need advanced software support beyond 30 days (other than basic installation and configuration), they can purchase a Dell DirectLine Plus for Linux contract. Dell DirectLine Plus provides phone support with 8x5 or 24x7 coverage, with a guaranteed response time of 2 hours for non-critical issues. Please note that customers requiring Enterprise class support for Linux should consider purchasing a product from the Enterprise family of products instead of Linux 9 Professional.

Because Linux 9 is a Linux “community” product, not all customer issues may be answered. Dell takes first call on all Linux support questions. If unable to provide the appropriate OS response, Dell will open an incident report to the Linux community via web, 'bugzilla', or RHN channels. Once the problem is resolved through these channels, Dell will close the issue with the customer. The PowerEdge server hardware comes standard with a three year limited warranty¹ supplemented with three years of Next Business Day On-Site² parts replacement and one year of On-Site¹ Labor Service.

In addition to its basic 30-day telephone operating system support for Red Hat Linux, Dell offers an enhanced suite of Professional Services, custom integration, and advanced performance computing (high-performance compute clusters, a.k.a. HPCC) to customers. Professional services vary by region. Please refer to the web sites below for more information:
