At VMGuru.nl we’ve done a lot of articles on VDI performance and best practices. Recently I’ve done an article on ‘How to improve VMware View video performance‘ and Edwin did an article on ‘Boosting Google maps and video with VMware View‘.

Researching the possibilities and changes with Horizon View 5.2, Eric Sloof pointed me to two new technical white papers.

VMware recently released two white papers, one on the performance and best practices for the new VMware Horizon View 5.2 and the second on the use of hardware accelerated 3D graphics with VMware Horizon View 5.2.

This is must read material for everyone who’s designing, planning and installing a VMware Horizon View 5.2 VDI environment.

Serial Port

While pursuing the 100% virtual mark you once in a while run into trouble with legacy hardware where there is hardware directly attached to the physical server you are going to virtualize. If it is USB equipment you can use USB Anywhere devices to make it happen, but if it is serial port connected equipment it gets harder to tackle that issue.

For instance you want to virtualize a building management system server with reading equipment connected to the serial ports. Is that possible? Yes you can!

It is possible to use a Virtual Serial Port Concentrator, as for instance the Avocent ACS V6000, which is described in this KB article and as mentioned in the vSphere 5 documentation here.

By connecting physical serial ports over the network with a virtual machine you can break the dependency of the physical layer and the OS layer. By solving this puzzle you can protect the organization against legacy hardware failure  and/or from software that nobody knows how it is installed anymore.

For years VMware has been busy creating a range of Horizon-like products. At VMworld 2009 there was already a preview of what the folks in Palo Alto were working on.
Since then a lot has changed, AppBlast was shown, Octopus came (and went again).

30 minutes ago VMware finally launched their new range of end user computing products called the VMware Horizon Suite.

So, what does Horizon consist of? Well, actually Horizon is the new name for the collection of ALL End User Computing (EUC) products VMware has to offer, some of which you already know and love, like VMware View and ThinApp. But now the new cool products are finally here!

So, what is VMware Horizon Suite? It consists of these products:

VMGuru used to run on an “ESXi only” install with no extra management. It’s a single server in a data center in Amsterdam, so there never was a need for a vCenter Server. When the VMware Octopus Beta started in which we participated, the deployment of the Octopus appliance required a vCenter server. So, instead of installing a full blown SQL server, a Windows server  etc., we decided to use the vCenter appliance.

With the introduction of ESX 5.1, a new vCenter also was introduced. The functions in the new vCenter Server Appliance have improved much so an upgrade is the way to go. Now when I tried this in my home lab, it went south big time and I ended up throwing everything away and starting over with a brand new vCenter install. For our server in Amsterdam I decided to do the upgrade again to show that it can be done properly. Now, VMware has a how to procedure in their knowledge base, but it’s very compressed and skips a few small steps, so we decided to write it out including screenshots to make it more accessible to all the folks out there who like to upgrade their vCenter Appliance but don’t know how.

More and more Microsoft SQL Servers are being deployed virtually in a VMware environment, but how can you license them correctly?

Microsoft changed their licensing again on April 1^st, 2012. With the general availability of SQL Server 2012, the changes around SQL licensing are live.

 Some highlights are:

• There are three main editions now:
  • Standard
  • Business Intelligence
  • Enterprise.

The Web edition is now only available for Service Providers through the SPLA license agreement.

• Per CPU licensing is no more. You have two types of licensing only:
  • Core-Based
  • Server+CAL licensing.

Microsoft chose this way because virtualization is on its way to 100%, server hardware gets more powerful over time, doubling cores every 18 months. Also companies demand more flexibility with workloads traveling between private and public clouds.

• Furthermore Microsoft tries to simplify and make licensing more predictable for customers with evolving infrastructures.

As a vExpert, we have a special place with VMware. Not just socially, but really, in the community pages. Usually this place is filled with news about new stuff coming out, reviews about software, technical questions, opinions and so on. A few months ago Mike Laverick, one of the valued members and a vExpert, posted a request to help him with the review of a book he and Barry Coombs were writing. There were no financial benefits, just a helping hand for charity.

So, I jumped on the bandwagon and a few weeks later I received my chapter to review in the mail. It was a very fine piece of work. And now the good news is, you can read it too! Not just one chapter, mind you. The whole book is finished and ready to download!

It’s all about building a desktop on VDI with VMware View. It’s all new and up to date and gets you up and running quickly as it is written by people who do this for a living all day, not just another theoretical dude. It’s a must-read if you plan to go the VDI way.

Now, why is this different, you say? Well, the digital version of the book is for sale for only 12,72 Euros at LuLu but that isn’t the best part. The best part is, you’ll be supporting Unicef when you buy it! The printed version will follow soon after, but as this is hot from the (virtual) press today, we didn’t want you to miss out on this brand new book.

More and more applications are supported on the VMware Platform, with the release of VMware vSphere 5 the boundaries of virtual machines have been expanded even more. Often we get questions about which applications are supported on the VMware virtual platform. There is a website page where you can search for specific applications and if they are supported by the software publisher.

You can search for an application by entering its title or the name of the software publisher.  Search results will display all supported software as well as applications that have already been submitted by other users.  If the application is not currently supported, you may Register/Login to vote and help VMware get the application officially supported sooner by the software publisher.

After VMware vSphere and View, VMware vCloud Director is the next big thing to setup and customers start asking for it. But the problem is that the knowledge and available resources are limited. So for real life implementations of vCloud Director we have to rely on VMware employees to show us the ropes.
First of all, what is VMware vCloud Director. In short, VMware vCloud Director gives enterprise organizations the ability to build secure private clouds as a base for a infrastructure-as-a-service (IaaS) solution. Coupled with VMware vSphere, vCloud Director delivers cloud computing for existing datacenters by pooling virtual infrastructure resources and delivering them to users as catalog-based services.

The vCloud Director architecture is shown below.

I often get questions about how to license Microsoft Windows 7 in a VMware View VDI deployment, I will try to elaborate what is needed in general and for specific scenarios. By understanding how they apply to common VMware View scenarios you can calculate and try to get the most out of existing and new licenses needed.

Every device you want to use to access the VMware View environment, with Windows 7 Desktops, needs to be licensed. It does not matter if it is a PC, a Thin or Zero client, an iPad or similar devices, every device accessing Windows 7 via VDI needs to be licensed.

You have two ways to license the environment, you can utilize the Software Assurance Windows Virtual Desktop Access Use Rights benefit at no additional cost; or you purchase Windows VDA subscription. Windows VDA is licensed per access device. There is currently no option to license Windows VDA per user.

VDA through SA or VDA subscription?

Certain devices, such as thin or zero clients, do not qualify for Software Assurance coverage for Windows. To license these devices for use with VDI you will need Windows VDA subscription. The rule of thumb is that if it isn’t a full blown Windows Desktop Operating System with Software Assurance (SA) you will need VDA subscription licenses to access the VMware View vDesktops.

VMware Next Step in End-User Computing roadshow June 2011 from Ton Hermes, Senior SE VMware on Vimeo.

The Future of End-User Computing goes much further than just delivering a vDesktop and vApplications to users. Users today are demanding more and more that functionality is available 24/7, where new functionality can be immediately obtained when needed and that they can use a device of their choice to work with.

For putting together a business case costs and revenues are an important part of it. If you want to calculate the direct resource costs associate with hosting a server in  your data center, you want to know the direct power consumption by the server in electrical costs and the costs associated with cooling the environment where the server is situated. To do so you will need a few parameters from the device(s) used. You will need the Watts, BTU/h and the electricity costs per kWh.

Where British thermal unit (BTU)  is used as a unit for air-cooling power of an air conditioning system and refers to the amount of thermal energy removed from an area. A BTU is approximately a third of a watt-hour. 1000 BTU/h is approximately 293W.  Kilowatt hour (kWh) is most commonly known as a billing unit for energy delivered to consumers by electric utilities.

Let’s take for example a HP DL-380 Generation 6 with two Quad core CPUs, 24 GB memory, eight  network ports, two  72GB 15K SAS hard disks with two 460 Watt power supplies. This server uses about 307 Watt and generates 1047 BTU.

Earlier this week I already told you that I’ve build a new ESXi whitebox but I had some problems installing it.

OK, first of all, what was the situation? I wanted to install VMware ESXi 4.1 Update 1 to a USB stick which is VMware certified.I plugged the USB stick into one of the USB ports on the back of my whitebox server and downloaded the ISO-image form the VMware website.

A quick installation and I’m ready to build my new lab environment. WRONG!

The installation fails with the following error:
‘Cannot install VMware ESXi 4.1 “Unable to find the system image to install’

August 2010 I wrote an article on support for Exchange CCR clustering on VMware with iSCSI.

VMware’s response then was very simple and straight forward. Exchange CCR clustering on VMware is not supported on iSCSI!

When asked if VMware had plans to change this support issue in the future the response was promising.

“The Exchange team within VMware requested the vSphere product team to support iSCSI for CCR and DAG clusters. They also would like to remove the RDM requirement for CCR and DAG.
Response from the product team is that they are testing and will update the support stance in a future release.”

Well, the future is now. I stumbled upon a VMware KB article, released May 5, which provides clear guidelines on the vSphere support status when running various Microsoft clustering solutions on VMware vSphere 4.

In the past, when I had to design a virtual infrastructure, I had a limited range of server hardware to pick from. Mainly HP and Dell or an occasional IBM server.

But since the beginning of this year I can not bypass Cisco. It is still a bit strange to some people when you mention Cisco with regards to server hardware but it’s a force we can’t ignore anymore.

When Cisco released their UCS server portfolio one and a half/two years ago, nobody thought they would storm the server market as they did. Certainly with their blade server solution they have a very appealing solution which can easily compete with HP, Dell and IBM blade solutions.

Personally I love to configure a Cisco UCS blade solution because it’s so freakin’ easy. One blade enclosure, one switch type, only two management entities and only seven different blade servers. This sounds a bit like a limited solution but trust me the possibilities are endless and performance is great.

Some time ago.. actually, a long time ago, we here at VMGuru.nl received a sample of a training DVD from TrainSignal. I promised to write a review on it, but I honestly didn’t come around to it due to all sorts of personal stuff. But the DVD box made it safely through the move from one house to the next. So, today I sat down and opened the DVD box.

So, first of all, it’s definitely a proper training. This isn’t your average ‘we demo, you watch’ kind of training. It’s aimed to let you pass the Exchange 2010 exam, but it does more. This 3 DVD box set covers all topics you  need to understand to successfully implement Exchange 2010 into an organization in 40 lessons. It does not only show you how and where to configure things, but most importantly, it tries to show you why. This is the first time I’ve encountered such an approach in a self-paced training package. It really is pretty extensive.

Yesterday VMware announced that it is ready to deliver the enterprise hybrid cloud with the availability of VMware vCloud Datacenter services.

For now this is only available from BlueLock and Colt and through beta services from Verizon.

VMware also introduced VMware vCloud Connector, a free plug-in that will allow deployment and management of virtual machines across VMware vCloud powered cloud services from within the VMware vSphere Client.

The vCloud Connector will be available for download in Q1 2011.

Last week we got a question concerning the licensing options around vSphere and how to choose the correct edition and options from all the flavors and options offered by VMware. So while answering the questions concerning the licensing I thought back to a nice overview picture we had available a few years back from VMware. So that’s why I compiled two overview pictures where there is one for the SMB market and one for the Enterprise market. In the overview the current situation and options are summarized per edition.

I was reading another article about cloud computing today. Almost all articles and posts seem to focus on how easy it is to add resources to your environment when you need more power.

Before you start to explain to me why this is true, yes, I do agree. It is very easy to add resources to an existing environment. When you use vSphere, Hyper-V or XenServer just add another host to your cluster or datacenter and you have more power that can be used by your machines. You can give virtual machines more CPU power and/or memory, etc. In the end your applications (that’s in the end what’s most important) have more chance for time to run on a shared environment.

My problem with this approach is simple: Aren’t we doing things the wrong way around?
