First Post!
Welcome to the Hot Lava Systems Blog. My name is Paul and I run Business Development at Hot Lava (http://www.hotlavasystems.com). On a fairly regular basis I'll be posting updates and announcements about what we are doing and where we'll be.
Mostly, this will be a running journal of my technical projects and the trials and tribulations which are inherent in those efforts. You'll be able to follow the dizzying highs and terrifying lows from the comfort of whatever distance that separates us.
Feel free to zip me an email at hotlavasystems@gmail.com. I trust their spam filters will suffice to keep the signal to noise ratio fairly decent; but if the message gets through but still can't pass the smell test, into the bin it will go. Otherwise, I'll be happy to read what you have to write.
I'll probably turn on comments at some point in the future, but at the moment, I don't have the resources to manage comments. So, this will be more of a monologue blog. A monoblogue, if you will.
My first big project is throughput testing using our six port 10Gbps ethernet card (http://www.hotlavasystems.com/products_10gbe.html). I'm using two of the Tambora 120 G6 cards and trying to determine the maximum throughput possible.
Preliminary testing has me at about 9 Gbps send and 9 Gbps receive on all six ports when running one port at a time. As I start running traffic through multiple ports simultaneously, throughput starts to drop off a bit.
Tomorrow, I am going to look at TCP overhead and develop some theoretical maximums so I can set my expectations appropriately. I will also be developing tables for number of ports carrying traffic and in what direction using a variety of TCP window sizes.
Exciting? You bet! I know there is a guy at NASA who says that he has consistently gotten up to 75Gbps bi-directional throughput. If I can replicate that, I'll be in good shape.
The goal is 100Gbps and I'm just at the 50% mark.
