Emulex 16GFC HBAs deliver up to 10 times better reliability to keep systems up and running

Posted May 1st, 2013 by Barbara Porter

A detailed reliability study by Emulex Labs shows that based on component selection, the Emulex 16Gb Fibre Channel (16GFC) Host Bus Adapter (HBA) can deliver up to 10x better reliability than QLogic’s newly released QLE2600 series. The LPe16000B was designed with reliability in mind, with a cool running ASIC and fail-proof passive heat sink for heat management within the server.

Emulex leads in reliability with the highest published mean time between failure (MTBF) in the HBA industry—10 million hours MTBF on the LightPulse family of 2G, 4G, 8G and 16GFC HBAs. For more information on why OEMs have deployed more Emulex LPe16000-series HBAs than any other 16GFC HBA, click here.

Sorry Mr. Competitor – Your Kung Fu Is No Good Here

Posted March 15th, 2013 by Sonny Singh

I am about to make a bold statement right now that will likely get me in me more hot water than Iranian President Mahmoud Ahmadinejad’s “cheek-to-cheek” performance at the funeral of Venezuelan President Hugo Chavez this week (if you have no idea what I am talking about, go on TMZ.com). So here it goes: I am utterly confident the sport of mixed martial arts (MMA) will surpass boxing and may even usurp established national icons, such as baseball and football in the foreseeable future based on MMA’s staggering growth predictions alone. At a bare minimum, MMA will steamroll over figure-skating and cardboard tube dueling (Yes, this is a real sport: http://www.tubeduel.com/) by 2014.

MMA is projected to grow into a multi-billion dollar industry within a few years and is considered the fastest growing sport in the world. To give you an idea of its growth potential, MMA recently went mainstream when the Ultimate Fighting Championship (UFC) organization “officially” evolved from the lunatic fringe of the sports world to a Fox TV rights deal, reportedly worth $100 million annually for seven years¹. The growth of MMA is commendable, and its established rules and regulations have shattered the idiosyncratic and anachronistic notions of a certain senator who once compared the sport to “human cockfighting.”

I’ll never forget when I witnessed Brazilian Royce Gracie use his unprecedented jiu-jitsu skills to famously decimate fighter after fighter who weren’t schooled in grappling and submission fighting in the early 90’s. Gracie fought against often much larger opponents who were practicing established martial arts including boxing, kung-fu, karate, judo and tae kwon do. He unequivocally demonstrated to the world of combat sports that it was indeed possible to beat opponents who were much larger, stronger and muscular than the average person. It was then and there I realized the importance of constantly evolving to be the best in any given arena.

Until that point, my adulation of the “Ultimate Fighter” consisted of one Ralph Macchio painstakingly deploying endless hours of wax-on, wax-off on Mr. Miyagi’s 1950 canary yellow Chevy convertible. Don’t get me wrong, Daniel-San’s flawless execution of that infamous Crane kick on Johnny’s poor head at that cinematic finale still sends shivers down my spine. But here’s the cold hard truth; Had Ralph Macchio used that flash-dance inspired crane kick on Royce Gracie back at UFC 1, he would have had the silly headband he wore on his forehead, instead wrapped around his neck and used to choke him out.

In the end, the true appeal of MMA comes down to its forceful evolution of prior one-dimensional martial arts into a multi-faceted, multi-disciplined combat sport that constantly demands its athletes equally evolve or be left in the dirt like a discarded Karate Kid 3 VHS tape. There is a reason why the elite fighters in MMA are considered the crème-de-la-crème of athletes in the world bar-none. I am vehement in my conviction that you won’t find a better specimen that embodies the rare blend of unrivaled athleticism, strength, agility, intellect and uncanny propensity for formulating and executing intricate game plans like you would in MMA.

The same comparison can be made for the ever-evolving, ever-changing and ever-converging world of technology. High-tech companies offering goods and services that are deemed a one-trick pony and fail to stay competitive, will also find themselves in the same category as B-movie actors like Jean-Claude-Van Damme and Dolph Lundgren with their straight-to –DVD films (with the exception of the Expendables 2 which deserved an academy award). Emulex is the MMA athlete of the tech world for the simple reason that our hardware and software solutions push the envelope for innovation, scalability and performance. Just ask our competitors (who won’t be named). Continue reading…

Benchmarking is Our Obsession. Ixia Helps Write the Black Book on CNAs.

Posted October 28th, 2009 by Emulex Labs Team

At Emulex Labs, benchmarking is our obsession. We are experts on benchmarking Fibre Channel. We run Iometer in our sleep. With the launch of our OneConnect™ Universal Converged Network Adapter (UCNA), we have become obsessed with IP benchmarking.

After examining some freeware tools, we found that the finest solution appeared to be from Ixia. Ixia’s highly scalable solutions generate, capture, characterize and emulate network and application traffic, establishing definitive performance and conformance metrics of network devices or systems under test.

We focused in on IxChariot, which contains Application Scripts to measure end-to-end network performance, the response time and throughput of application transactions across the network.

Ixia provides a library of free, pre-defined scripts that you can easily, extensively customize to reflect the unique character of application traffic on your network. Application Scanner lets you automatically create scripts for any custom or commercial application without having to understand the scripting language.

IxChariot:

  • Creates Transmission Control Protocol (TCP), User Diagram Protocol (UDP) and RTP IxChariot scripts and Ixia hardware stream definition files from line traces generated by protocol analyzers
  • Creates scripts for TCP and UDP (including RTP) applications that use Winsock calls
  • Creates IxChariot application group definitions from Winsock traces and from line traces generated by protocol analyzers
  • Automatically generates scripts based on a Winsock trace, performing optimization where needed
  • Traces all Winsock traffic to help you better understand the interaction of applications with multiple connections or processes
  • Enables generation of IxChariot scripts that preserve the timing delays contained in the source trace files.
  • Enables creation of scripts for applications running on non-Windows clients
  • Presents details about the traces you record
  • Enables you to select a single application stream from a line trace, create a script for that stream and edit the script as required
  • Allows you to combine multiple streams into a single script
  • Loads line trace files that contain IPv6 network traffic, and generates Ixia stream definitions corresponding to the IPv6 traffic
  • Generates IxChariot scripts that include large payload files

Ixia’s customer support was phenomenal. As we spoke, they became quite interested in our benchmarking Fibre Channel over Ethernet (FCoE). Our discussions led to joint development in the area of benchmarking processes for the new converged networks. Together, we drafted an Ixia Black Book on CNAs.

As a primer on the technology and testing of CNAs, the Black Book begins with an introduction to CNA technology, the developments that led to the FCoE protocol and data center network convergence. It includes detailed test plans using Ixia’s IxVM, a tool for measuring the performance of virtualized systems, which guides the reader through key tests required to thoroughly measure the performance of a CNA. Step-by-step instructions include using IxChariot™, a component of IxVM, to measure TCP throughput, UDP throughput, latency and storage input/output (I/O) performance in virtualized and non-virtualized environments.
