I finally received some new servers in the Atmos lab and…well, I thought I’d share with you!!!  These are Cisco C200 M1 servers and they’re loaded out in the following config:

ProcessorsIntel Xeon 5520 (2.27Ghz quad cores w/Hyperthreading)

Memory: 4Gb DDR3 ECC/Registered x 12 for a total of 48Gb memory

NICs: Dual ServerEngines Gigabit Ethernet NICS + dedicated IPMIKVM-over-IP NIC

Enjoy the video!!!!

UPDATE:  YouTube does SD (standard definition) processing first and HD processing second.  if it looks terrible now, just wait and it’ll look better.

Why FCoE is a GOOD thing…

by dave on December 22, 2009


This is a tongue in cheek video that I took in one of my labs showing why, for no other reason but fabric reduction, that CEE/DCE/FCoE is a valuable thing for ANY IT infrastructure.

A couple of things you’ll notice here are:
a.) it’s loud. Sorry about that…this lab is in a thermal chamber and it gets crazy loud.
b.) I’m running Qlogic 2562 HBAs (fibre channel) and Qlogic 5802V switching (more switches are coming)
c.) My GigE switches are, in a word, terrible (with the distinct difference being the Foundry/Brocade switching which is good).
d.) I copt a TERRIBLE NorthEastern accent…I don’t even know where it came from…

Anyhow, this Flip UltraHD recorder is pretty awesome…

It’s always exciting to me to see the chatter around a new standard or new “way” of doing storage. Fibre Channel over Ethernet (FCoE) has certainly had it’s share of chatter as well as the inherent criticisms from detractors. There have also been questions regarding the inevitable overlap with other technologies like iSCSI that are able to accomplish much of the same functionality without, perhaps, having to re-invent the wheel. What follows in this post is a series of responses to several questions and postings on the web on FCoE. I would like to note that my comments are mostly reductionistic and don’t represent as deep of a stream of thought as perhaps merited by the topic.  [click to continue…]

Fibre Channel over Ethernet or Infiniband: a Response

December 8, 2008

Over at Cisco, there is a post from April, 2008 on the FCoE vs. IB argument that was written by Dante Malagrino. What follows is MY perspective (not my employers) on the FCoE vs. IB argument that he puts forth.
a.) Historically, both IB and FC have been more difficult to manage than competing […]

Atmos Foundations: Hardware

November 11, 2008

Yesterday, I took a look at Atmos from a software standpoint.  While Atmos is truly a “software” solution, there is an element of hardware to examine as well.  Truth be told, it’s not as interesting as the core Atmos offerings but, there are some notables.  We’ll start with a quick look at 3 basic configurations […]
