iWARP

LNI is a founding member of the iWARP consortium, working in conjunction with the iWARP community to create a comprehensive set of test tools that accelerate the delivery of a conformant and interoperable iWARP product to the market.

iWARP Technology

As network speeds move into the 10 Gigabits per seconds and higher range, an increasing percentage of the CPU is lost processing network traffic. In an effort to recapture these CPU cycles for application processing RDMA (Remote Direct Memory Access) technology was standardized. RDMA technology reduces the amount of time a CPU must spend performing buffer copies and processing interrupts, resulting in improved application performance. Standardized RDMA solutions were first introduced to the market though InfiniBand. InfiniBand, however, required a new networking infrastructure, leaving organizations with legacy Ethernet networks out in the cold. With the introduction of RFCs 5040, 5041, and 5044 the IETF defined a standard for performing RDMA within the context of the Internet Protocol, independent of the underlying physical network. Within the RDMA industry these RFCs are called the iWARP RFCs and the products related to these RFCs is loosely termed iWARP technology.

iWARP Overview

LNI iWARP Offerings

LNI has been involved with the standardization of iWARP technology since 2003 and now offers a full set of products and services for organizations working with this high performance RDMA protocol.

• For detailed corner case, conformance, and negative testing LNI provides a complete conformance test suite that addresses all elements of the iWARP protocols as defined in RFC 5040, 5041, 5044.
  
  
• For interoperability, stress, system, and performance testing LNI provides XANStorm, a traffic generation tool that operates at the RDMA protocol level.

LNI provides contracted services related to iWARP development and testing. These services include turnkey system, conformance, interoperability, and performance testing. LNI also develops regression suites and consults in the implementation of effective iWARP QA programs.

iWARP Conformance Test Suite

LNI offers an automated test harness that implements the iWARP conformance test suite.

The test suite comprehensively addresses all the testable items of the iWARP wire protocol as defined in RFC 5040, 5041, and 5044. This includes a number of complex test cases that require detailed manipulation of the underlying TCP connection and validation of memory regions within the device being tested. The iWARP conformance test suite can run as a set of command line tests, or as part of LNI’s context-rich test harness (XTC). The iWARP
conformance test requires the use of the LNI RDMA agent.

Complete list of iWARP testable items

XANTest commander (XTC) is LNI’s automated test harness.
XTC has the following user-friendly features:

1. Easy to use GUI
2. Flexible, customized automated test runs
3. Generates detailed reporting in an easy to read PDF format
4. Result files displayed in context-rich environment

XTC runs on minimal hardware, a PC with Linux or Windows operating system and an Ethernet card. XTC provides conformance, negative, and regression testing in a format that is easy to use by the domain expert or the entry-level QA engineer.

Custom Engineering Solutions

LNI provides contracted services for the development of custom regression suites for iWARP. As authors of the updated test suite LNI has the expertise and insight needed to offer turnkey product testing.
