Switching

To deliver the performance required by the applications, in addition to powerful servers with high-speed processors, a low latency, very high bandwidth communication network was required. This type of network was originally implemented as the HiPS, evolving later to SP Switch, and then to SP Switch2. A new management function for the complex IBM eServer pSeries environment had been developed and named Cluster Systems Management (CSM). CSM provided the basic management functions required by a cluster based on either IBM eServer pSeries or xSeries, or a combination of the two server types. Because CSM did not support existing SP Switch technology, a new switch technology was needed, the IBM eServer pSeries High Performance Switch (HPS). tech news

This paper provides an introduction to the IBM eServer BladeCenter. This introduction includes an overview of the BladeCenter technology and hardware, for the chassis and the blades. In addition, it takes a look at blade management and the options that are currently available. This paper presents the advantages of blade servers over other servers in the market, where the blade servers fit into the market, and why the market is driven towards blade servers. tech news

A series of four benchmark tests were completed to evaluate GPFS performance for HPC applications on Linux clusters. The clusters in this test were x345-based systems using FAStT900 disk controllers and EXP700 disk drawers. Each test was conducted on a different cluster network configuration [Gigabit Ethernet (GbE), bonded GbE, 100 Megabit Ethernet (MbE), and Myrinet]. This paper summarizes and interprets the results of this test. tech news

This paper discusses the features and functions of the GbESM and how it is managed. It also introduces some networking terms and concepts to the users and administrators of the IBM eServer BladeCenter product. It also provides step-by-step instructions for establishing the initial network configurations to ensure that Layer 2-7 GbE Switch Module is configured correctly and is operable so one can begin immediate communications across the network. tech news

This paper positions the Cisco Systems Intelligent Gigabit Ethernet Switch Module for the IBM eServer BladeCenter and describes how it enhances the BladeCenter value proposition by seamlessly interfacing into a customer's existing data network. This paper helps one plan, install, and configure the new Cisco Systems Intelligent Gigabit Ethernet Switch Module for several network topologies. tech news
