Clearing Up the Bad Reputation of VMware's Paravirtualized Drivers

In 2009, not too long after the release of VMware vSphere 4.0, I blogged about the use of PVSCSI and VMXNET3; specifically, I mentioned reasons not to use PVSCSI and VMXNET3. A lot has changed since then, so—prompted by a reader who shall remain nameless but knows who he/she is—I thought it might be prudent or useful to post a brief update.

Additional RecoverPoint-VAAI Update

In late October and early November 2010 I published a couple of articles on interoperability between EMC RecoverPoint and VAAI (vStorage APIs for Array Integration, part of VMware vSphere 4.1). If you’d like to go back and read those articles for completeness, here are the links:

Changing the IP Address on a VPLEX Management Server

EMC VPLEX leverages a Linux-based management server as an integral part of the overall architecture. The management server, as the name implies, provides the management interfaces—both HTTPS (web-based) and CLI—for managing the VPLEX cluster(s). In a VPLEX Local configuration, changing the IP address is a single-step process; in a VPLEX Metro configuration, there is an additional step required. In this post I’ll walk you through both situations.

Looking Back, Looking Forward

Everyone else is doing it, so I figured I might as well also: publish something about how the site fared during 2010. I’m going to do that, yes, but I’m also going to talk a little bit about my commitments to the site (and to the readers) for 2011.

New vSphere Resource by Train Signal

David Davis of Train Signal recently dropped me an e-mail to alert me to the release of a new series of videos titled VMware vSphere Troubleshooting Training. Having watched a fair number of the Train Signal videos—I used them while prepping for my CCNA exam late last year and have watched many of the vSphere videos—I’m confident in saying that this will be a valuable resource for anyone who is interested in learning more about vSphere and how to troubleshoot vSphere. This is especially true for users who are new to vSphere. (I know it’s hard to believe that some users are new to vSphere, especially for the long-time users, but it is very true.)

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!

Merry Christmas!

I’d like to take this moment to wish all of my readers a very happy, very joyous, and very blessed Christmas holiday. Don’t forget the reason for the season (Luke 2:10-11)!

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.

Using VPLEX and Data Replication Together

This post is a follow-up to a couple of previous posts on VPLEX. In this post, I'll build on the information in those earlier posts to show how it is possible to use VPLEX in conjunction with a data replication solution. (Read more...)
