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 SAN Connectivity for Oracle VM2007-11-01 Emulex
  Oracle has now entered the virtual server arena with the introduction of Oracle VM. Oracle VM is a powerful and easy to use solution that delivers the benefits of server virtualization and allows users to create and manage multiple Virtual Machines (VM) hosted on the same physical server but behaving like independent physical servers. Each VM possesses its own virtual CPUs, network interfaces, storage and operating system. In addition, with Oracle VM, users have access to an easy to use, rich, graphical interface to create and manage their virtual environments. Oracle VM offers an enterprise-class, scalable, high-performance platform for server virtualization. Oracle VM includes two components: Oracle VM Manager and Oracle VM Server.

whitepaper IBM Proventia Server Intrusion Prevention System for Linux2007-11-01 IBM
  IBM Proventia Server Intrusion Prevention System (IPS) for Linux software supports compliance regulations that require security against malicious threats which may compromise servers and sensitive data. With Proventia Server IPS, enterprises can protect against data breaches and benefit from capabilities that simplify and support compliance requirements. Proventia Server IPS for Linux benefits extend beyond compliance support by serving as a critical component in an organization's Data Loss Prevention (DLP) strategy. With trends in measuring the cost of server breaches based on cost per compromised record vs. server downtime, a comprehensive DLP strategy with Proventia Server IPS will enable real-time reporting on data and applications and provide data loss prevention and preemptive protection while enforcing corporate security policies for servers.

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 Persistent Naming Using Udev in Linux Environments2007-07-26 QLogic
  QLogic has been delivering industry leading Fibre Channel (FC) solutions in Linux. QLogic offers a wide range of management tools for Linux that ease the burden on Storage Area Network (SAN) administrators. These tools include SANsurfer FC HBA Manager with GUI and CLI interfaces, diagnostic tools, and utilities. In addition, the QLogic FC Linux driver qla2xxx includes comprehensive support of new features (such as udev) included in the Linux 2.6 kernel. This white paper provides a detailed set of instructions that allow SAN administrators to use udev functionality to build a persistent naming scheme for storage devices (LUNs) connected to QLogic FC Host Bus Adapters (HBAs).

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 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 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 A New Business Model to Drive Business Intelligence Acceptance and Adoption2007-06-13 Pentaho
  Business Intelligence (BI) is a well-established and generally well-known software category that spans a wide range of functional capabilities. Specific definitions will vary from customer to customer and vendor to vendor, but most will agree that business intelligence typically refers to the challenge of providing business users with meaningful information from company data sources to help those users make better, more informed business decisions. Traditionally, it has been time-consuming and expensive for a given customer to evaluate, select, purchase, and maintain the right BI technology to address their needs. While information on BI is readily available from many different sources, customers still face significant challenges relative to time, expense, and accuracy throughout BI technology investigation, vendor engagement, and final technology selection.
