Future Storage Systems: A pause in workflow

October 17, 2008

Since I started this article series, I’ve had the awesome opportunity to have my ideas (well, some of the early articles at least) reviewed by person(s) who deal with the actual infrastructure of storage systems day in, day out.  The benefit of such peer review is that you get to learn at the symbolic “feet” of the masters and discover flaws, omissions, and understated features that need to be understood and incorporated.  This post is dedicated to some of those discussions and, where applicable, my understanding of how the FSS either incorporates or misses the boat.

Future Storage Systems: Part 4: Operating System – Conceptual Overview

October 13, 2008

In the previous Future Storage System articles, we’ve covered the basic hardware foundation for what I envision to be a powerful future-oriented storage solution for the commercial midrange.  However, as you’re probably aware, hardware is meaningless without software to provide the operational capabilities that are needed to mange information.  In this article, I will focus on a general design for an extensible software layer (an OS) that will provide future-oriented capability expansion as well as robust analytics, capabilities, and integration with business continuity principles.  As always, please reference the diagram below.

Future Storage Systems: Part 3b – I/O Expansion Node

October 10, 2008

In Part 3a, we discussed the possibility of a purpose-driven Compute Node based on the Torrenza initiative for the Future Storage system.  This expansion node made use of Hypertransport as a “glue” between the base storage compute node and the expansion node (of computation or I/O flavours) that could be added.  The advantages of that topology were simple:  hot add support for additional processing power, additional I/O bandwidth within the system, and additional computing power for the array OS (which we’ll cover in a later article).  In this overview, we’ll take a look at another variation on an expansion node: an I/O expansion node that will add additional front-end ports and/or functionality to the base system.  We will be referencing the diagram below. (Apologies in advance for the image shearing off in the lower right hand corner).

Future Storage Systems: Part 3a – Node Expansion Overview

October 9, 2008

In the previous two articles on the Future Storage System (FSS), I took a general look at a basic storage system architecture (Part 1) and then went a bit deeper into some of the more interesting bits of that system from a platform standpoint (Part 2).  In this article, I want to dive a bit deeper into how I envision nodes to be building blocks for additional capabilities and processing directives.  I will be referencing the image below as part of this article.

Future Storage Systems: Part 2 – Detailed Node View

October 8, 2008

So, in my article yesterday, I gave a global view of a very simple storage system for the future. Since I LOVE this type of conjecture and theoretics (is that a word?), I decided to take this a step further and flesh out some of the other intricacies of the design.  Check out the image below and then click through to read the rest.

Why wouldn’t the following work? (Future Storage System: Part 1)

October 7, 2008

So, I’ve been toying around with this in my mind for some time.  Essentially, I’ve tried to understand the basic “Storage Processor” limitation of current storage systems and propose an admittedly simplistic design to get around some of the difficulties.  The biggest hurdle, in my mind, is to have cache coherency, low latency memory access to other nodes in a “cluster,” and have a communications “bus” between nodes that is extensible (or at least will grow bandwidth with more devices on the signal chain).  Staring at that problem, then, look at the image below.

Something Cool! (AMD + Tyan content)

One of the things I do in my spare time is develop rendering systems for a client in another country.  The cool thing about this is that I’m able to use cutting-edge AMD processors and platforms from Tyan and nVidia in order to accomplish these goals.

I just found out that one of my rendering systems was used to process the following Coca-Cola commercial for the 2008 Summer Olympics!!!  There is a little special trick to this system, however, that warrants a closer look. Read the rest of this entry »
