  • HP SN3000B Fibre Channel Switch Quickspecs
    QuickSpecs HP SN3000B Fibre Channel Switch Overview To remain competitive, IT organizations must keep pace with ever-increasing workloads without a similar increase in their budgets or resources. While virtualization has provided some relief by enabling the benefits of faster deployment and consolidation, it also tends to put additional stress on data center networks. In addition, the move toward cloud computing, which promises greater efficiency and a more service-oriented business model, means that these networks will face even greater demands. The HP SN3000B Fibre Channel Switch meets the demands of hyper-scale, private cloud storage environments by delivering market- leading 16 Gb Fibre Channel technology and capabilities that support highly virtualized environments. Designed to enable maximum flexibility and investment protection, the SN3000B Switch is configurable in 12 or 24 ports and supports 4, 8, or 16 Gbps speeds in an efficiently designed 1U package. It also provides a simplified deployment process and a point-and-click user interface-making it both powerful and easy to use. The SN3000B Switch offers low-cost access to industry-leading Storage Area Network (SAN) technology while providing "pay-as-you-grow" scalability to meet the needs of an evolving storage environment. The SN3000B is available in two models: HP SN3000B 16Gb 24-port/24-port Active Fibre Channel Switch HP SN3000B 16Gb 24-port/12-port Active Fibre Channel Switch DA - 14277 Worldwide — Version 6 — March 25, 2013 Page 1 QuickSpecs HP SN3000B Fibre Channel Switch

  • Infiniband Event-Builder Architecture Test-Beds for Full Rate Data
    International Conference on Computing in High Energy and Nuclear Physics (CHEP 2010) IOP Publishing Journal of Physics: Conference Series 331 (2011) 022008 doi:10.1088/1742-6596/331/2/022008 Infiniband Event-Builder Architecture Test-beds for Full Rate Data Acquisition in LHCb Enrico Bonaccorsi and Juan Manuel Caicedo Carvajal and Jean-Christophe Garnier and Guoming Liu and Niko Neufeld and Rainer Schwemmer CERN, 1211 Geneva 23, Switzerland E-mail: [email protected] Abstract. The LHCb Data Acquisition system will be upgraded to address the requirements of a 40 MHz readout of the detector. It is not obvious that a simple scale-up of the current system will be able to meet these requirements. In this work we are therefore re-evaluating various architectures and technologies using a uniform test-bed and software framework. Infiniband is a rather uncommon technology in the domain of High Energy Physics data acquisition. It is currently mainly used in cluster based architectures. It has however interesting features which justify our interest : large bandwidth with low latency, a minimal overhead and a rich protocol suite. An InfiniBand test-bed has been and set-up, and the purpose is to have a software interface between the core software of the event-builder and the software related to the communication protocol. This allows us to run the same event-builder over different technologies for comparisons. We will present the test-bed architectures, and the performance of the different entities of the system, sources and destinations, according to their implementation. These results will be compared with 10 Gigabit Ethernet testbed results.

  • Test, Simulation, and Integration of Fibre Channel Networked Systems by Mike Glass Principal Marketing Engineer Data Device Corporation
    Test, Simulation, and Integration of Fibre Channel Networked Systems By Mike Glass Principal Marketing Engineer Data Device Corporation September 2006 Test, Simulation, and Integration Of Fibre Channel Networked Systems Introduction Fibre Channel is a high-speed networking technology deployed on a number of military/aerospace platforms and programs. These include F- 18E/F, F-16, F-35, B1-B, B-2, E-2D, the Apache Longbow and MMH helicopters, and AESA Radar. Applications for Fibre Channel include mission computers, processor and DSP clusters; data storage; video processing, distribution, and displays; sensors such as radar, FLIR, and video; serial backplanes and IFF. Basic characteristics of Fibre Channel include a choice of copper and optical media options; 1 and 2 Gb operation, including auto-speed negotiation; and operation on multiple topologies including point-to-point, arbitrated loop, and switched fabric. In addition, Fibre Channel provides low latency to the single-digit microsecond level; address scalability with a space up to 224 ports; broadcast and multicast operation; unacknowledged and acknowledged classes of service; a means for providing variable quality of service (QoS); and multiple upper layer protocols (ULPs). Test and simulation applications for deployable Fibre Channel networks include the development of board and box-level systems and sub-systems, network integration, production test, and equipment maintenance. For software development and network integration, it’s often necessary to rely on Fibre Channel testers and analyzers to simulate unavailable equipment for traffic generation and monitoring. Some development and integration environments provide demanding requirements for real-time data monitoring, storage, and subsequent offline analysis. For production test and field maintenance, low cost testers are often better-suited than higher-priced analyzers.
