Technology Short Take #9

Welcome to Technology Short Take #9, the last Technology Short Take for 2010. In this Short Take, I have a collection of links and articles about networking, servers, storage, and virtualization. Of note this time around: some great DCI links, multi-hop FCoE finally arrives (sort of), a few XenServer/XenDesktop/XenApp links, and NTFS defragmentation in the virtualized data center. Here you go—enjoy!

An Introduction to the VPLEX CLI

The VPLEX command line interface (CLI) is a bit different than a lot of other CLIs with which I’ve worked. In some respects, it’s similar to the scope-based CLI that Cisco uses with Unified Computing System (UCS). In this post, I’d like to explore the VPLEX CLI a bit and provide a brief introduction to the VPLEX CLI. Keep in mind that this is just an introduction—for a complete reference to the VPLEX CLI, I’ll refer you to the VPLEX product area on EMC PowerLink where a complete VPLEX CLI User’s Guide is available in PDF.

FCoE through a Nexus to a MDS-Attached Storage Array

In this post, I want to pull together all the steps necessary to take a Converged Network Adapter (CNA)-equipped server and connect it, using FCoE, to a Fibre Channel-attached storage array. There isn’t a whole lot of “net new” information in this post, but rather I’m summarizing previous posts, organizing the information, and showing how these steps relate to each other. I hope that this helps someone understand the “big picture” of how FCoE and Fibre Channel relate to each other and how they interoperate (which, quite frankly, is one of the key factors for the adoption of FCoE).

Now that I’ve managed to get my VPLEX clusters up and running, I’m ready to start providing some posts on VPLEX and how it’s configured and used. To get things started, I want to first provide an overview of VPLEX storage objects and how they relate to each other.
