PCIe® Interposer analyzes traffic between HBA and blade servers.
June 28, 2011 - Mechanically inserted into blade server backplane between it and ExpressModule, PCIe® ExpressModule(TM) interposer enables Summit(TM) T3-16 and T3-8 PCIe protocol analyzers to capture, decode, and display all traffic on PCIe bus for system troubleshooting, debugging, and monitoring. This I/O host bus adapter (HBA) card supports PCIe 3.0 specification data rates to 8 GT/s and minimizes signal interference via use of TAP(3) technology. Lane widths of x1, x4, and x8 are available. SANTA CLARA, Calif. -- PCI-SIG DevCon -- LeCroy Corporation, a leading supplier of oscilloscopes and serial data test solutions, today introduced a new PCI Express® (PCIe®) ExpressModule(TM) interposer that supports PCI Express 3.0 specification data rates up to 8 GT/s. The new ExpressModule interposer, designed for use with the LeCroy Summit(TM) T3-16 and T3-8 PCI Express protocol analyzers, provides the ability to easily analyze data traffic between high performance ExpressModule HBA cards and ExpressModule-based blade server systems. An ExpressModule is an I/O HBA card based on the PCI Express specification that is mechanically inserted into an ExpressModule-compatible blade server backplane. The ExpressModule HBA technology enables higher reliability, performance and manageability providing high speed performance utilizing PCI Express 3.0 specification speeds of up to 8 GT/s. Debugging the protocol traffic between the PCI Express 3.0 ExpressModule and chassis backplane can be challenging due to tight mechanical tolerances. The PCI Express 3.0 ExpressModule interposer connects between the backplane of the chassis and the ExpressModule, and enables the analyzer to capture, decode and display all traffic on the PCI Express bus for troubleshooting, debugging and monitoring system performance. This new interposer minimizes signal interference by using LeCroy's T.A.P.(3) technology, allowing protocol traffic between the ExpressModule and backplane to be analyzed while inside the chassis. This insures that the equipment under test can function normally while data traffic is analyzed so that any protocol problems can be quickly identified and solved. The ExpressModule interposer is offered in x1, x4, and x8 lane widths, with data rates operating at up to 8 GT/s. "Developers that are integrating PCI Express 3.0 ExpressModule HBAs onto next generation ExpressModule based Blade servers can now utilize LeCroy's extensive suite of PCI Express 3.0 protocol analysis equipment," said John Wiedemeier, Product Marketing Manager for PCI Express Protocol Solutions, LeCroy. "The ExpressModule interposer makes it possible to analyze backplane signals on ExpressModule blade servers, such as the Oracle blade server, insuring maximum interoperability and testing that results in high reliability." LeCroy protocol analyzers have been at the forefront of PCI Express development tools. All LeCroy protocol analyzers feature a hierarchical display, real-time statistics, protocol traffic summaries, detailed error reports, powerful scripting, and the ability to create user-defined test reports, which allow developers to troubleshoot intricate problems and finish their projects on time.

EMC PowerPath VIEWER, One Console to rule them all.. « Itzikr's Blog
The PowerPath “powermt display”CLI command provides specific information that helps users trying to identify and isolate infrastructure and array issues. However, it can be tedious to issue this command on each individual host, when there are tens or maybe even hundreds of hosts in the data center.
the Solution: PowerPath Viewer v.1.0 SP1
PowerPath Viewer version 1.0 provides a great solution for easily monitoring configurable “alerts” for hundreds of PowerPath Hosts. This utility accepts the type of data normally shown with the powermt display command from each monitored PowerPath host and displays the consolidated information on a centralized management station. Users can see the big picture for their storage infrastructure, or drill down for details. Information is displayed in a user friendly GUI. Note: PowerPath Viewer version 1.0 is a controlled release and the first deliverable of a vision to provide centralized GUI-based monitoring and management of a multi-host PowerPath environment. PowerPath Viewer is ECUE-compliant (EMC Common User Experience) meaning it has the same look and feel as other EMC software management tools.
PowerPath Monitored Events
Events reported by the PowerPath Driver are shown in this diagram. If you are setting up multiple PowerPath Viewer Consoles, you may want to use a CSV (comma separated value) file. The Read CSV File feature reads hostnames from a .txt file that is stored on your PowerPath Viewer host and automatically populates the hostnames contained in the .txt file to the IP Address(s) or Host Names(s)field in the PowerPath discovery wizard.
