whitepaper Running Linux on the PlayStation 3: More Than a Toy2008-03-18 IBM
  The Sony PlayStation 3 (PS3) runs Linux, but getting it to run well requires some tweaking. In this paper, first in a series, Peter Seebach introduces the features and benefits of PS3 Linux, and explains some of the issues that might benefit from a bit of tweaking. When Sony first announced that the PlayStation 3 would be able to run Linux natively, a great deal of excitement ensued. Early on, it was a bit of a challenge to get Linux natively installed. The supported installer ran a custom script that hand-mangled a Fedora Core 5 or 6 install DVD into a runnable system with a special PS3 kernel. People put in hours and hours of effort to get other systems, such as Ubuntu, working.   
whitepaper Hosting Data Center Networking With Vyatta2008-03-10 Vyatta
  This paper will show how Vyatta open-source software combined with off-the-shelf x86 hardware can be leveraged to perform most routing and firewall requirements in the hosting data center at a fraction of the cost of closed proprietary systems. While proprietary networking equipment vendors have created discrete hardware product categories and price points based on arbitrary performance segmentation, open networking systems are proving that a single system can be continually upgraded to perform the same tasks. Vyatta solutions can be deployed at multiple points in the hosting data center from the backbone to the customer cage resulting in better performance and significantly faster Return On Investment (ROI).

whitepaper Evaluating Open Source Software for Your Business2008-01-01 Pathfinder Development
  This paper looks at the strange world of open source IT decision making that can get in the way of good decisions. The exuberant IT manager sees open source like found money or a snow day; if it's free and good, why bother with the evaluation? Let's just use it. The cynical IT manager sees open source as a toy or a joke; people get what they pay for, so why bother looking at open source? Both of these attitudes miss the mark. When it comes to open source, people should evaluate it like any other software they are considering for their company.   
whitepaper Red Hat Enterprise MRG: Realtime Whitepaper2007-11-16 Red Hat
  Many enterprise workloads have extremely demanding requirements for determinism - to ensure predictable response times at the 20 microsecond latency level. The difficulty has been that until now, all realtime operating systems have been niche offerings - absent of any COTS (Commercial Off The Shelf) products. Red Hat is uniquely positioned to provide these capabilities due to its proven trackrecord of development and mainstream accepted Linux kernel realtime enhancements. In response to strong customer demand, Red Hat is productizing its realtime kernel in an offering called Red Hat Enterprise MRG, comprised of high speed messaging, realtime kernel, and grid cluster scheduler.

whitepaper Build Your Own Oracle RAC Cluster on Oracle Enterprise Linux and iSCSI2007-11-01 Oracle
  One of the most efficient ways to become familiar with Oracle Real Application Clusters (RAC) 11g technology is to have access to an actual Oracle RAC 11g cluster. There's no better way to understand its benefits - including fault tolerance, security, load balancing, and scalability - than to experience them directly. Unfortunately, for many shops, the price of the hardware required for a typical production RAC configuration makes this goal impossible. A small two-node cluster can cost from US$10,000 to well over US$20,000. That cost would not even include the heart of a production RAC environment - typically a storage area network - which can start at US$10,000.

whitepaper ITIL: Microsoft and Open Source2007-10-26 Microsoft
  Organizations live and die based on the efficiency, reliability, and security of Information Technology (IT). Because of this, IT must be fully aligned to the needs of all customers, internal and external. The Information Technology Infrastructure Library (ITIL) provides a strategy to define, implement, and monitor that alignment across the full spectrum of IT processes, ranging from Incident and Problem Management to Security Management. This paper focuses specifically on the choices available from Microsoft and the open source community. Both offer solutions which can assist critical elements of ITIL. Some solutions are similar, while others are distinctive. This paper gives examples of different approaches to the issues which ITIL raises.

whitepaper Internals of the RT Patch2007-06-30 Red Hat
  Over the past few years, Ingo Molnar and others have worked diligently to turn the Linux kernel into a viable Real-Time platform. This work is kept in a patch that is held on Ingo's page of the Red Hat web site and is referred to in this paper as the RT patch. As the RT patch is reaching maturity, and slowly slipping into the upstream kernel, this paper takes the user into the depths of the RT patch and explains exactly what it is going on. It explains Priority Inheritance, the conversion of Interrupt Service Routines into threads, and transforming spin_locks into mutexes and why this all matters.   
whitepaper ACPI in Linux - Myths Vs. Reality2007-06-30 Intel
  Major Linux distributors have been shipping ACPI in Linux for several years, yet mis-perceptions about ACPI persist in the Linux community. This paper addresses the most common myths about ACPI in Linux. When users boot in ACPI-mode instead of legacy-mode, the first thing they notice is that the power button is now under software control. In legacy-mode, it is a physical switch which immediately removes power. In ACPI mode, the button interrupts the OS, which can shutdown gracefully. Indeed, ACPI standardizes the power, sleep, and lid buttons and the OS can map them to whatever actions it likes. In addition to standardizing power button events, ACPI also standardizes how the OS invokes software controlled power-off.   
whitepaper Concurrent Pagecache2007-06-30 Red Hat
  This paper presents a concurrent pagecache for Linux, which is a continuation of the existing lockless pagecache. Currently the pagecache is protected by a reader/writer lock. The lockless pagecache work focuses on removing the reader lock, however, this paper presents a method to break the write side of the lock. Firstly, since the pagecache is centered around the radix tree, it is necessary to alter the radix tree in order to support concurrent modifications of the data structure. Secondly, pagecache is adapted, by removing all non-radix tree consumers of the lock's protection, and extend the pageflag, introduced by the lockless pagecache, into a second per page lock.   
whitepaper SUSE Linux Enterprise 10 SP1: Virtualization Technology Support2007-06-01 Novell
  SUSE Linux Enterprise Server 10 provides integrated Xen-based virtualization, which can be used to provision, de-provision, install, monitor and manage multiple Virtual Machines (VMs) on a single physical system. Out of the box, it can create VMs running both modified, highly tuned, paravirtualized operating systems and unmodified operating systems. Xen serves as the hypervisor, or VM monitor. It is a layer of software that runs directly on the server hardware and controls platform resources, sharing them among multiple VMs and their operating systems by presenting virtualized hardware interfaces to each VM.
