whitepaper Configuring IBM TotalStorage for Oracle OLTP Applications2005-11-09 01:00:02
  This paper offers a technique for achieving highly balanced I/O across the entire ESS (or other IBM TotalStorage) I/O subsystem - thereby optimizing overall I/O performance. This technique requires minimal knowledge of the specific application(s) to be deployed or their underlying I/O characteristics and virtually eliminates the need for manual data file placement or ongoing I/O performance tuning.   
whitepaper Optimized Linux Code for Intel XScale Microarchitecture2006-12-22 01:00:22 Intel
  This paper outlines recommendations to be made to the software architecture of a software product running on I/O Processors (IOPs) using Intel XScale microarchitecture. The objective of the recommendations is to optimize the overall system performance by making enhancements to the software architecture used with external storage products. As a result of the increased usage of Linux on IOPs using Intel XScale microarchitecture, Intel has identified several recommendations to the software architecture that can be made to improve the overall system performance.   
whitepaper Hot-Debug for Intel XScale Core Debug2006-12-22 01:00:22 Intel
  The purpose of this white paper is to explain the benefits of and the implementation requirements for Hot-Debug for Intel XScale micro architecture I/O processors. Traditionally, when a debugger is used through a Joint Test Action Group (JTAG) connection, the processor is reset at the beginning of the debug session. For standalone applications, this is acceptable, but I/O processors are mostly used for Central Processing Unit (CPU) off load and add-in cards where there is a host system which configures all of the devices on the bus. The start of a debug session on an add-in card or a host bus adaptor causes a reset and consequently the bus configuration of the add-in card is lost.   
whitepaper FICON Express2 Channel Performance Version 1.02005-04-01 IBM
  This white paper was developed to help IBM field sales specialists and technical representatives understand the performance characteristics of FICON Express2 channels. FICON Express2 channels are a new generation of FICON channels that offer improved performance capability over previous generations of FICON Express and FICON channels. They are being introduced on the IBM eServer zSeries 990 (z990) and zSeries 890 (z890).

whitepaper Measuring CPU Overhead for I/O Processing in the Xen Virtual Machine Monitor2005-12-22 01:01:52 Hewlett-Packard
  Virtual Machine Monitors (VMMs) are gaining popularity in enterprise environments as a software-based solution for building shared hardware infrastructures via virtualization. In this paper, using the Xen VMM, the authors present a light weight monitoring system for measuring the CPU usage of different virtual machines including the CPU overhead in the device driver domain caused by I/O processing on behalf of a particular virtual machine.   
whitepaper Linux Device Drivers: USB Drivers2005-01-28 O'Reilly Media
  The Universal Serial Bus (USB) is a connection between a host computer and a number of peripheral devices. It was originally created to replace a wide range of slow and different buses - the parallel, serial, and keyboard connections - with a single bus type that all devices could connect to. USB has grown beyond these slow connections and now supports almost every type of device that can be connected to a PC. The latest revision of the USB specification added high-speed connections with a theoretical speed limit of 480 MBps.

whitepaper Diskeeper Can Boost Your SQL Server's Performance2007-01-19 01:00:27 SQL Server Bible
  One of the biggest hardware bottlenecks of any SQL Server is disk I/O. And anything that a DBAs can do to reduce SQL Server's use of disk I/O will help boost its performance. Some of the most common things DBAs do to reduce disk I/O bottlenecks include; Tuning queries to minimize the amount of data returned; Using fast disks and arrays; Using lots of RAM, so more data is cached; Frequent DBCC REINDEXing of data to remove logical database fragmentation. Another less frequently used method to reduce overall disk I/O, but nonetheless important, is to perform physical defragmentation of SQL Server program files, database files, transaction logs, and backup files.   
whitepaper DB2 UDB Version 8.2 Enhancements for Linux2005-11-09 01:00:02
  IBM was an early supporter of Linux and continues to demonstrate technology and market leadership on this platform. Enhancing DB2 for Linux environments and exploiting the Linux kernel has been an important part of the continuing evolution of DB2 UDB. This paper discusses some of the features of DB2 UDB v8.2 that are unique on Linux platforms. There are many other Version 8.2 features that are common across platforms and are also available on Linux.   
whitepaper Micro Industries Creates Simpler, Lower Cost Custom Mini-NLX Designs With Intel Communications I/O Controller Hub (C-ICH)2005-06-15 03:00:01
  As an ambulance races toward a nearby emergency room, paramedics use mobile instrumentation to collect data on the patient's condition and instantly download it to a receiving station at the hospital. This case study discusses how Micro Industries mini-NLX form factor board products - based on the high-integration Intel 82801E Communications I/O Controller Hub (C-ICH) - are helping OEMs deliver sophisticated and reliable instrumentation like this at a significantly reduced cost.
