Video: Dell R610 Overview in Lab

by dave on January 14, 2010


I figured I’d start the year off right and give all of you a bit of an overview on the Dell R610 hardware that I use in my test and development work.  Got 6 of these guys in the other day so, I shot a quick video overview of the hardware and specs for you to take a look at.

I don’t mention the HBAs or CNAs that I use (Brocade, Emulex, and Qlogic) because it does vary a bit depending on the loadout that I’m working with.  Common denominator to everything, though, is VMware ESX4i.

If there’s anything else you want me to provide an overview on, please let me know!

cheers,

Dave

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…

Frosting the FCoE Cake…

by dave on November 2, 2009


Czech kind of sponge cake.

I was advised the other day that a certain manufacturer was adopting a rather interesting model for Fibre Channel over Ethernet CNA licensing.  Rather than simply purchasing a FCoE CNA with all the features (10GbE, iSCSI, and FCoE) turned on, they were going to adopt some sort of staggered licensing model that put each of those features as an option that you could license (and pay for) at a later date.

When I read this, the analogy that sprung to mind was one of, well, cake.  (I’m not a foodie, I just tend to think abstractly of food.) How many people go to a bakery and buy a plain cake that isn’t frosted and that has a payment plan against it?   You’re going to buy a cake that fits with the mindset of what a cake should be; that is, something that is complete and “ready to eat.”  Additionally, you’re probably not going to be interested in a plain cake where the end cost is greater than a pre-frosted cake!  Why would you buy something that required an order of magnitude more effort to get to a final, workable order?  You’d consider someone who bought into this idea as somewhat of a lunatic.

Life with Qlogic’s 5802V: Part 1

October 21, 2009

If you follow me on Twitter at all, you’ll know that I’m a big fan of Qlogic.  I appreciate the functional simplicity of what Qlogic designs encompass as well as the “get business done” attitude that they bring to their switches, HBAs, NICs, and CNAs.  Imagine my happiness, then, when I got ahold of one […]

Emulex E3S: Fitment

June 30, 2009

In my first article on the Emulex E3S Gateway, I simply relayed a high-level look at the device as well as a sample diagram of how integration would look within a very simplistic block-based environment. Overall, it appears that the concept of a hardware “gateway” to the cloud is very well accepted as a mechanism […]
