Infiniband


It’s always exciting to me to see the chatter around a new standard or new “way” of doing storage. Fibre Channel over Ethernet (FCoE) has certainly had it’s share of chatter as well as the inherent criticisms from detractors. There have also been questions regarding the inevitable overlap with other technologies like iSCSI that are able to accomplish much of the same functionality without, perhaps, having to re-invent the wheel. What follows in this post is a series of responses to several questions and postings on the web on FCoE. I would like to note that my comments are mostly reductionistic and don’t represent as deep of a stream of thought as perhaps merited by the topic.  [click to continue…]

Infiniband Ports: Voltaire ISR-6000 Infiniband...

Over at Cisco, there is a post from April, 2008 on the FCoE vs. IB argument that was written by Dante Malagrino. What follows is MY perspective (not my employers) on the FCoE vs. IB argument that he puts forth.

a.) Historically, both IB and FC have been more difficult to manage than competing IP-based solutions (though I’d argue that IQDNs are as much of a pain as node addresses and WWNs).  With the advent of truly GUI driven switching solutions, a LOT of the legwork required has been reduced both for FC and for IB.  Matter of fact, a true novice to both protocols can get a solution set up and running with a hour or two (cabling and hardware setup included).

n Parts 1-4 of the Future Storage Systems articles, we focused on the SAN-facing technologies that would enable scalable propcessing growth, purpose-built technologies for deduplication and encryption, as well as the fabric that would tie nodes together.  However, in each of these articles, I never got into WHERE  that information would eventually be stored.  Today, I’m hoping to remedy that problem.  I’ll be referencing the diagram below as usual.

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 […]

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 […]
