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 Folksamerica Reinsurance Company Executes on Strategic Vision for Companywide Information Accessibility0000-00-00 NetApp
  Folksamerica Reinsurance Company is a leading multiline broker market reinsurer and a wholly owned subsidiary of White Mountains Insurance Group, Ltd. The Folksamerica vision involved the virtualization of user workstations using Citrix software to provide reliable, secure, and device- and location-independent access to information companywide. To support this goal, the IT team was tasked with building a storage infrastructure that would deliver maximum uptime, enable disaster recovery within hours, improve efficiency, facilitate rapid growth, and require minimal administrative resources. After several months of evaluation, the Folksamerica team determined that the optimal solution for their Citrix MetaFrame environment would involve Network Appliance storage.

whitepaper QLogic Switches Give CNBC an Edge With Improved Production Time2007-07-01 QLogic
  To compete with other networks, CNBC makes programming compelling by providing a daily stream of animation, illustrations, and designs that vividly explain the business world to viewers. Each production staff member used a Mac Pro workstation with local storage and a 4TB Apple Xsan file server for shared files. But the storage system was slow and lacked sufficient throughput to handle all production workflow. CNBC deployed primary and backup Storage Area Network (SAN), each with a QLogic SANbox 9000 Fibre Channel Switch, two Apple Xserve servers, and an 18TB Apple Xsan file system; both SANs are connected via Fibre Channel to an Apple Xserve server that provides the mirroring function between the two SANs; 10 Apple Mac Pro workstations.

whitepaper Oracle 10g Release 2 Performance and Tuning on an IBM System p Linux on POWER Platform2007-06-30 IBM
  This paper discusses performance considerations when setting up an Oracle Database 10g Release 2 on Linux on POWER (LoP) platforms. Recent Linux kernel enhancements such as huge page support, IBM POWER5+ 64 KB pages, libhugetlbfs, Fibre Channel and network adapter enhancements and other kernel processor tunings can be deployed to bring enterprise class performance to Linux. The contributors discuss how to easily setup, deploy and configure these performance features and discuss the performance gains using an OLTP workload on a 128 GB 8-core (16-threads) IBM System p5 570 server. Relative performance results are given for each improvement as well as discussions on 4-core and 8-core scaling results.

whitepaper Siemens Shanghai Mobile Communications Consolidates Critical Infrastructure on NetApp SAN Storage0000-00-00 NetApp
  Siemens Shanghai Mobile Communications Co. Ltd. (SSMC) is Siemens's biggest manufacturing facility outside Germany and the largest Siemens operating company in China. The telecom market in China in the past years has grown substantially, driven by China's tremendous economic growth and rapid modernization. As a result, SSMC has had to substantially increase its production to meet demand in China and around the globe. SSMC decided to standardize on SAP to integrate all of its business applications, including financials, production planning, and logistics. SSMC deployed a 6TB NetApp Fibre Channel SAN storage solution, with two NetApp systems clustered for high availability.

whitepaper Physical-Layer Considerations for the Realistic Deployment of Impairment-Aware Connection Provisioning2007-06-15 Institute of Electrical and Electronics Engineers
  Nowadays, impairment-aware connection provisioning is a hot topic due to the evolution of optical networks to all-optical infrastructures and to the need to maintain or enhance Quality of Service (QoS). Most of the research efforts in this field use complex, analytical models of impairments as the basis for the connection provisioning decision. However, these models are not fully feasible in practice due to cost, monitoring limitations and the architectures of impairment-aware Routing and Wavelength Assignment (RWA). This paper discusses key physical-layer considerations for the realistic deployment of impairment-aware connection provisioning, and provides an example of cost-effective, distributed Impairment-aware RWA (IRWA) in the context of the all-optical ADRENALINE testbed.

whitepaper Radio-Over-Fiber Transmission of 1.25-Gigabit Ethernet Signal on 60-GHz Band Subcarrier With Performance Improvement and Wavelength Reuse2007-06-01 Institute of Electrical and Electronics Engineers
  With Radio-over-Fiber (RoF) enabled remote antenna, Gigabit Ethernet service operating at 60-GHz frequencies can be accessed cordlessly. Due to limited linear operation region of 60-GHz optoelectronic modulators commercially available so far, optical weak modulation is required leading to limited link performance. This paper demonstrates in RoF transmission of 1.25-Gigabit Ethernet signal on 60-GHz band subcarrier, the fiber downlink performance is improved by suppressing the optical carrier-to-sideband ratio based on the usage of a simple and low-cost fabricated 2×2 all-fiber optical interleaver. Simultaneously by using the interleaver, the downlink optical carrier is recovered and is reused as optical source for fiber uplink hence laser-free access point is achieved.
