Moving Lab Manager Datastores

You might have noted a slight incompatibility between VMware vCenter Lab Manager and one of VMware vSphere’s core features, Storage VMotion, in this earlier post on VMware Lab Manager design considerations by former co-worker Aaron Delp:

Using IP-Based Storage with VMware vSphere on Cisco UCS

I had a reader contact me with a couple of questions, one of which I felt warranted a blog post. Paraphrased, the question was this: How do I make IP-based storage work with VMware vSphere on Cisco UCS?

EMC Celerra Optimizations for VMware on NFS

Recently Jason Boche posted some storage performance numbers from his EMC Celerra NS-120. Out of those storage performance tests, Jason noted that the NFS performance of the NS-120 seemed a bit off, so he contacted EMC’s vSpecialist team (also known as “Chad’s Army”, but I like vSpecialists better) to see if there was something that could or should be done to improve NFS performance on the NS-120. After collaborating internally, one of our team members (a great guy named Kevin Zawodzinski) responded to Jason with some suggestions. I wanted to reproduce those suggestions here for everyone’s benefit.

Congrats to Hyper9

I received an e-mail from David Marshall of Hyper9 (David also runs VMBlog.com) with some good news: Hyper9 has had their strongest quarter yet, despite the less-than-ideal economic conditions. Hyper9’s Virtual Environment Optimization (VEO) is a pretty well-regarded solution, and based on the limited hands-on time I’ve spent with it I like it. So, congratulations to Hyper9 for providing a bright spot in the economic landscape. Well done, guys!

Thinking Out Loud: It's Not Just the Technology

I had a quick thought this morning while browsing this post by Lori MacVittie. She, in turn, was referring back to a post published on VMBlog.com about a virtualization prediction that 2010 would be the year that the network becomes fluid and virtual. (As a side note, the original article on VMBlog.com appears to be primarily a marketing exercise for a company that purports to help make the network fluid and virtual.)

Resetting the Root Password on VMware ESX 4.0

Earlier today, I had to reset the root password on a lab server running VMware ESX 4.0 Update 1. For some reason, the password we assigned yesterday when we built the server from scratch wasn’t working this morning. OK, no big deal, right? Just reboot the server into single user mode and away you go. I won’t bother to repeat the steps for getting into single user mode; go to this article and it will give you what you need (the article is written for ESX 3.5 but it works fine for ESX 4.0).

A Couple GeekTool Scripts

I’ve been experimenting with GeekTool, a nifty Mac OS X Preference Pane that allows you to display information on your desktop. This information can be static text, images, or the output of a script. The last option is the most useful one, in my opinion, and that’s where I’ve been putting GeekTool to use for me. This isn’t going to be some long post on how to use GeekTool or why you should install it; rather, I just wanted to share a couple of short scripts that I wrote that you might find useful.

VMware, Zimbra, and Why I'm Not an Analyst

The rumors are swirling that VMware is going to buy Zimbra, an open source e-mail platform currently owned by Yahoo. You’ve probably all read the various news articles about the rumors and the events leading up to the rumored acquisition, so I won’t bother you with them again.
