Looking for a visual representation of Microsoft Server 2008 and it’s various new enhancements? Go to the Microsoft.com downloads pages and download the Windows Server 2008 Component Posters. The Server 2008 poster is divided into six product scenarios. There is a virtualization scenario and a Server Core scenario.

Some info about the posters from Microsoft’s page:

These two posters, originally published in the July 2007 issue of TechNet Magazine, provide a strong visual tool to aide in the understanding of various features and components of Windows Server 2008. One poster focuses exclusively on powerful new Active Directory technologies, while the other provides a technical look at a variety of new features available in Windows Server 2008 (such as Server Core, Network Access Protection, and more).

Get the originals from the link above, or I have saved copies locally on my Files page.

Here is a screenshot of the virtualization scenario. Click the image for a larger version. Read the rest of this entry »

I am certainly not the first to talk about the differences between VMware Workstation, VMware Server and VMware Player. However, this topic of conversation continues to come up. “Why should I buy VMware Workstation when I can download Server or Player for free?” There are some key differences between the products that you should understand before you decide which is right for you.

One of the engineers from our storage team asked me to join a discussion about whether or not restoring VMs from images made by any of the live VM backup utilities would be a reliable process for a client. I unknowingly joined what was really a battle about whether the client would be better off using SAN based snapshots, host based replication, or live VM imaging specifically for Exchange and SQL VMs. All are proven solutions, and depending on budget, recovery objectives, and service level agreements all solutions could be deployed with confidence. The customer, and this post, is focused on the live VM backup solutions and their reliability for Exchange and SQL. Based on cost of implementation and infrastructure required the VM backup tools are the most affordable and easiest to deploy, but they also leave you with the most uncertainty.

Before continuing I want to point out that normal backup agents still need to be used for Exchange and SQL VMs. Not one of the VM backup solutions can perform application maintenance or specialized backups, like the Exchange Information Store backup for example. Understand that the live VM backup tools only specialize in capturing a quiescent, working image of the VM operating system and application.

First let’s understand what we mean when we say quiescent data. In the latest VMware Virtual Machine Backup Guide quiescing is defined as: Read the rest of this entry »

Bush – Everything Zen

Xen, XenSource, XenServer, and Zen. What are they? Which one do I use to virtualize my servers? What is Citrix’s product and how does it compare to VMware? These are my reasons for writing this post. Frankly, I was confused. After some intense meditation I decided to figure it out. Unfortunately, Lakers coach Phil Jackson was not available to help.

Wikipedia was where I started my journey. At first I was even more confused when I landed on the Xen (disambiguation) page: Read the rest of this entry »

IT20.info has created a good multi vendor virtual infrastructure feature comparison which can be found at Virtual Infrastructure products: features comparison.

What distinguishes this table from Wikipedia’s comparison is that it is focused only on hardware virtualization solutions that are the most relevant in the market today. The author has done a great job weeding out all the less known vendors and allows you to more easily compare VMware vs Microsoft vs Virtual Iron vs Citrix vs Xen.

John Troyer from VMTN Blog wrote about this matrix in his Virtual Technology Comparison post and brings up a great point: Read the rest of this entry »

Looking for a comparison of VM backup solutions? PHD Technologies, makers of esXpress, have put together a matrix of features comparing how their product stacks up to VMware’s VCB, Vizioncore’s vRanger, and even vRanger integrated with VCB.

Check it out online in original form here.

I have saved the matrix as a stand alone page as well.

Vizioncore’s vConverter 3 claims to be faster than both Platespin’s PowerConvert and VMware’s VMConverter.

“vConverter enables lightning fast and easy conversions without disrupting the source physical system during the conversion process. There are never any reboots, no need to visit machines being converted, no software to install on the source and no downtime. A significant R&D effort and focus on conversion reliability and efficiency has resulted in the fine tuning of read/write/transfer algorithms and the creation of several mechanisms which result in impressive speed and conversion completion metric.”
