Fibre Channel over Ethernet

Video: Dell R610 Overview in Lab

by Dave Graham 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

Frosting the FCoE Cake…

by Dave Graham 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

by Dave Graham on 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 of their latest “edge” fibre channel switches, the SANbox 5802V.  The SANbox 5802V follows the typical edge-switch formula: 20 SFP ports for either 4Gb/s SFPs or 8Gb/s SFP+, 4 stacking ports that default at 10Gb/s Fibre Channel connection and can be upgraded to 20Gb/s FC when additional bandwidth is needed, a serial and IP-based management port setup, and dual redundant power supplies (the 5802V ships with 2 PSUs; the 5800V model ships with only 1).

FCoE: “Soft” FCoE Integration

July 2, 2009

There appears to be quite the interesting discussion going on over at Scott Lowe‘s blog regarding FCoE (Fibre Channel over Ethernet) as its relationship to the data center, VMware, and, pretty much everything else. I love watching people put their thoughts to eletronic ink (via the comments section) but recently, I’ve had some pretty interesting [...]

Moving from Block to Cloud: Emulex E3S

June 18, 2009

It’s not often that I get excited about technology within the storage space. There are notables, of course, mostly that take my love for high bandwidth interconnects (e.g. Infiniband, Rapid I/O) and mash them up with high-speed storage (EFDs, Fusion-IO). That being said, when it comes to the cloud, I’m absolutely estatic when off-the-shelf [...]
