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

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

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

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

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.

Fleshing out the Hypertransport Storage System

Off to Orlando…

Well, I’ll be in Orlando, FL for the next few days soaking up some good ‘ol EMC goodness (that’d be product, not sun ).  I should have some really interesting things to report on this month including more information on the CMIS “platform” (announced last month by EMC, IBM, and Microsoft) as well as some newer technology that’s coming in the the following months.  Also, will have a review of the excellent Qlogic 5802V 8gb/s fibre switch available online in a bit as well.

Stay tuned!  Things are going to be interesting.

cheers,

Dave
