With SUSE Linux Enterprise Server experience the very best that open source has to offer. SUSE Linux Enterprise Server (SLES) is a Linux distribution is targeted for servers, mainframes, and workstations but can be installed on desktop computers for testing as well. SUSE Linux Enterprise Server is designed to work with Windows and other operating platforms, making it the ideal choice for mixed environments.
SUSE Linux Enterprise Server includes best-in-class application security. When combined with other security best practices, you effectively protect your critical systems and data from external and internal threats.
SLES 11 sp3Installing SUSE Linux Enterprise Server Installing SUSE Linux Enterprise Server (SLES 11 sp3)SUSE Linux Enterprise Server is a Linux operating system which focuses its attention on mainly servers, mid-range and mainframe. SLES as it is commonly known is mainly used by larger organisations/Enterprises.
SLES is generally more stable than the open community edition with only maturely tested products making their way into this edition. SLES 11 is available to download as an evaluation. It can be downloaded for many platforms including x86, AMD64/Intel64, System Z, IBM Power and Itanium editions. SLES normally comes with 60 days support, providing patches and fixes. Larger platforms often offer longer evaluation periods.
After the initial period, you will need to purchase a license agreement for continued support of your operating system.To download your evaluation iso image of SLES 11 you will need to register for an account at the following site:In the following example I will be using a 32bit x86 platform image of the operating system (SLES-11-SP3-DVD-i586-GM-DVD1.iso). Note only DVD1 is needed. Once you have downloaded your SLES iso image for the relevant architecture, this image will need to be burned to a DVD. Software that can do this task can be found by searching for 'dvd iso burning software' in the search box located above.
Your system may already have the necessary CD/DVD burning software installed such as 'Brasero, K3B, Nero, CDBurnerXP or Roxio'. Once you have successfully burned your 'iso' image of SLES 11 to your DVD, you will need to place the DVD into the DVD drive bay of your target system and reboot your system.
(This example assumes you are using a x86 32bit version of the software). As your computer reboots, you will need to press the appropriate key to access your system's BIOS configuration settings. On many systems this key will be 'F8', 'F11' or 'F12'. Most systems will display the a message indicating which key needs to be pressed.
Once you have access to your BIOS settings, you will need to modify the boot order of your system to boot from CD/DVD first. Once this change has been made, you can reboot your system and follow the instructions below.

SUSE Linux Enterprise Server 11 SP4 for x86SUSE Linux Enterprise Server is a highly reliable, scalable and secure serveroperating system, built to power mission-critical workloads in physical,virtual and cloud environments. SUSE Linux Enterprise Server is an affordable,interoperable and manageable open source foundation that enterprises can use tocost-effectively deliver core business services, enable secure networks andeasily manage their heterogeneous IT resources, maximizing efficiency andvalue. SUSE Linux Enterprise Server provides market-leading usability, seamlessinteroperability with existing IT systems, and virtualization capabilities asboth host and perfect guest.
More SUSE Linux Enterprise Server 11 resourcesThree years ago, it still seemed a sure thing that Xen was the way to go for Linux virtualization. Even though it was rough around the edges, version 10 of SLES was among the first enterprise Linux systems to include a usable Xen stack. Since then, many things have changed. Epson 4000 adjustment wizard program download. Citrix Systems Inc.
Acquired XenSource, the company that was founded by the people who invented, and it became apparent that Xen was a decent, but complicated, virtualization offering.Most users feel that Xen has moved away from the open source market toward Citrix. When most people think about Xen virtualization, they think about.
And version 5 is available nowadays for free. Solution providers can still make money by offering the tools used with XenServer.Another issue is that the biggest virtualization player on the market, VMware Inc., has added some new features to its latest release, vSphere 4, including paravirtualization, which was once unique to Xen. VMware has proven that it is mature and still is, beyond any doubt, the market leader in virtualization.To make things even worse for the Xen stack, another alternative became popular in the Linux world:. The selling point of KVM is that it is just a simple kernel module that is updated with the Linux kernel itself - not a complex product that needs many patches. And it also offers the same major features as Xen. The fact that KVM is taken seriously in the virtualization market was demonstrated when Ubuntu and Red Hat, both major players in the Linux enterprise server market, announced that they would drop Xen as their default virtualization solution.In response to these moves, Novell Inc.
Had to make a statement about its direction in the Linux virtualization market, where some interested customers are implementing Citrix XenServer and others look mostly at KVM, which is practically owned by Red Hat. Red Hat recently purchased the company that developed KVM technology and therefore is now the major player in the KVM arena.SUSE Linux Enterprise Server 11At first sight, the message that Novell delivers in SLES 11 seems clear: Xen is improved, and there is better integration of Xen in the server software. For instance, there are now installation patterns for a Xen virtualization host, a fully virtualized guest machine and a paravirtualized guest.While installing SLES 11, you can now select from three different installation patterns that are all related to virtualization.Also, SLES 11's networking configuration is much improved. By default, Xen uses a network bridge, which could be managed only with scripts until last year's release of SLES 10 support pack 2. You can manage SLES 11 by using the SLES generic management utility -.
In addition, the graphical part of Xen management has improved somewhat, though it is not spectacular. The virt-manager utility is still the default management tool, which administrators who are used to managing VMware or Citrix XenServer will find to be a very limited utility.The Xen virtual network bridge can now be managed easily from YaST.Virt-manager, the default management tool for a Xen environment, has improved only slightly.Despite the small improvements in Xen, the real change in SLES 11 virtualization is found in a product that is not supported by Novell.
SLES 11 now includes a technology preview version of KVM. During the launch of SLES 11 in the Netherlands, Kai Dupke, senior product manager for outbound server at Novell, said the preview is just to show customers that KVM is also available in SLES. Novell doesn't want people to choose another distribution just because they aren't aware of KVM. Dupke could not make any promises with regard to the future of Xen in SLES.' The market seems to want KVM as the Linux virtualization solution, and if that is true, we will offer KVM,' Dupke said. So the virtualization issue has not been settled yet in SLES.
I am already looking forward to the release of SLES 12, probably coming in 2012.About the authorSander van Vugt is an independent consultant from the Netherlands.
