December 2008


I’m typically in the position of designing storage solutions for external customers based upon established protocols and best practices here at EMC.  We design based on our work with Microsoft, Oracle, SAP, etc. and the solutions development that happens with these partners.  It’s definitely an exciting challenge to take a customer’s needs and wrap them into a solution set that allows for performance, capacity, and future growth.  What’s even more exciting, however, is getting the chance to design and implement a storage solution for an internal “customer.”  I figured this would be a good chance to lay out the work that goes on in designing a storage solution coupled with a VMware host solution as well.

I’ll break this journey into several parts and include the appropriate Visios (as permitted).  So, without further ado, let’s get started!!!

Great Overview Video on FCoE!

by dave on December 15, 2008


This YouTube video was done by a good friend of mine, Stu Miniman @ EMC. This video provides a VERY good overview of Fibre Channel over Ethernet (FCoE) and an basic fabric implementation. Enjoy!

Storage Fabric Lifecycles: An Overview

by dave on December 12, 2008


Continuing the thread of explaining the roles of storage fabrics that we’ve come to know and love (FCoE, Infiniband, 10GbE iSCSI, etc.), @rjhintz asked the following question:

What’s the expected technical life of a storage fabric install today before it’s upgraded to a new generation or forklifted out?

There are a few significant events that precipitate storage fabric changes:  the acquisition of technology that requires the change and CapEx/OpEx spend/reduction/allocations. That isn’t to say that incentivized fabric overhaul offerings don’t make any impact, but rather they’re the exception versus the rule.  Additionally, there are other factors that feed into infrastructure overhauls but are beyond the scope of this general discussion.  Let’s look at each of these metrics more closely.

Moving a Fabric forward: FCoE Adoption and other Questions

December 9, 2008

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 […]

Fibre Channel over Ethernet or Infiniband: a Response

December 8, 2008

Image via Wikipedia

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 […]
