Back in April I wrote a blog aimed and the differences between ESX and ESXi. The original post was written for ESX 3.5 and with the introduction of vSphere I think it’s about time i have revisited this topic and looked at the pros and cons of ESX4 and ESX4i. Now before we dig into the technical details there is one big thing you should all be aware of. The FAQ page published by VMware states “VMware ESXi is the recommended platform for both new and existing customers. Future hypervisor releases will solely be based on this architecture.”
For most that should be enough said. After reading that I would seriously start rolling out ESXi in a lab and start figuring out how I could maintain my needs without the service console most of us have become to know and love. I would also start brushing up on the RCLI as well as the PowerCLI if you are currently dependent on scripts that run in the service console. The good news is almost everything you do today in the service console can be achieved one way or another with ESXi as well. OK with that said lets talk about some of the other limitations.

I’m sure many of you have run into an issue with setting up Citrix Xen Desktop (DDC). As i was setting up a new “Desktop Group” I ran into a problem when trying to configure the vCenter SDK address. The configuration wizard show you an example that looks say ‘For example, https://VirtualCetner.example.com/sdk” which is what you would expect to use and you would also expect it to work. Think again. When you try to setup your vCenter SDK address you will be presented with and error “The hosting infrastructure could not be reached at the specified address.” Citrix takes security serious so unless you plan on replacing the default SSL certificate on your vCenter server you will need to hack out a work around. Now I would agree that in production you should replace the default SSL but if your just trying to spin up a demo or test environment it can be a hassle.
So I searched the web over and over and found a number of threads with many of ways to resolve the issue only none of them seemed to work for me. However a combination of a number of things that I found did. So I’m here to save you the trouble of finding all of various pages with partial solutions. Below you will find exactly what you need to do to make this work.

We all have come to love many free services that we have integrated into our daily lives. Things like free email, free voice mail, free open source applications, free video streaming, social networking sites, operating systems, and many other services that make our lives better. At dailyhypervisor.com we are working on a new type of free service that can help all of you in the technical community. A free community lab. A free community lab would provide access to an environment that would grant everyone the opportunity to learn IT hands on and provide the ability for those who don’t have the means to test and learn about new technologies.
Tackling something of this scale will not be easy, but with help from the community hopefully we can make this something extraordinary. I personally will be donating some of my own lab equipment to the first generation of this lab environment. I’m currently working on building the lab for early beta testing by the end of March 2010. The first generation of this lab will consist of 3 servers running ESX4i. The servers have limited resources but each one consists of a single Quad-Core AMD Phenom 9850 processor, 8GB of Memory and access to 1TB of NFS storage. Access to the lab in the beginning will be by invite only much like other beta offerings. If you are interested in participating and leveraging this opportunity please register with dailyhypervisor.com and post a comment to this blog post stating your interest in participating. In your post please provide a brief description of how you would leverage this and also anything you would like to see available in the lab. All early beta users will be also to provide feedback on the lab and may be asked to participate as environment moderators once the lab goes GA. Much like community forums the goal is to make this community driven and supported by user moderators and the such.

I have been a big fan of VMware products for a very long time, since the release of VMware Workstation 1.0 actually. I run VMware workstation on Windows, on Linux, and as of recently VMware Fusion on my MacBook. I was telling a friend of mine about how much I like my new MacBook as I have traditionally been a PC guy for many many moons and he asked if I was running “Parallels” on it. I had no idea what he was talking about as I had never pain much attention to parallels before. Well if you have never heard of them or ever seen their desktop virtualization products I highly recommend that you do.
Here is a link to their Workstation 4.0 Extreme demonstration. Just click the demos button and watch the video. After watching this video I think I need to buy a few more monitors and some extra video cards because I have got to try this out.

The Infrastructure Planning and Design team has released a new guide: Microsoft Enterprise Desktop Virtualization.
This guide outlines the critical infrastructure design elements that are crucial to a successful implementation of Microsoft Enterprise Desktop Virtualization (MED-V). The reader is guided through the four-step process of designing components, layout, and connectivity in a logical, sequential order. Identification of the MED-V server instances required is presented in simple, easy-to-follow steps, helping the reader to deliver managed virtual machines to end users. Following the steps in this guide will result in a design that is sized, configured, and appropriately placed to deliver the stated business benefits, while also considering the performance, capacity, and fault tolerance of the system.
