VMGuru.nl – I choose (a virtual) life!

May 21th VMware released their new flagship product VMware vSphere 4 which should bring us tons of new features and performance improvements.

But how is the vSphere experience almost 9 months later?

Starting with the installation and setup experience, my personal experience with vSphere is very good. During the installation and setup of VMware ESX or ESXi 3.x I experienced a lot of issues like BIOS settings causing HA issues, HA issues when changing the ESX IP addresses, Problems with VMware Update Manager and faulty HP USB sticks. We even created a HA checklist for you to easily address HA issues.

Once up and running ESX(i) 3.x ran fine with the occasional HA error which 99% of the time could be fixed by reconfiguring HA from Virtual Center.

Now with vSphere the installation and setup is simple, error free and straight forward. Setup HA in the cluster properties wait for all progress indicators to reach 100% and you’re done.

Based on the real life results when virtualizing XenApp I thought it was about time to summarize some of the best practices for virtualizing XenApp servers.

Why we DO want to virtualize XenApp?

1. For server consolidation:  vSphere enables scale up XenApp deployments;
2. For mixing server editions: 32-bit and 64-bit XenApp VMs can coexist;
3. For management: Better management through flexibility & isolation think about Change Management and VMware DRS;
4. For high availability and disaster recovery: VMware HA and vCenter Site Recovery Manager;
5. For less costs for server hardware, maintenance contracts, power, cooling, floor and rackspace.

Virtualizing XenApp servers is very complex. There are a lot more layers involved, like the type of hardware, the capabilities of the processor, the performance of the shared storage, the hypervisor used, the specific settings per hypervisor, operating system settings in a virtual environment, the XenApp settings in a virtual environment, the Workspace management settings in a virtual environment etc, etc.

In the following sections I tried to summarize some of the best practices we use in our projects:

At the end of May of this year we wrote a article concerning Hypervisor comparisons and we got a lot of positive feedback on it. The downside to that is that people want an update as soon as one of the companies launches a new version of its product, and who can blame them. However the issue is that this takes a lot of research and because of that, a lot of time. And because two of us are ill and in bed wearing a sombrero and the other two are extremely busy, we simply don’t have that time right now.

However, Scott Lowe has written an excellent article on the feature comparison between VMware vSphere 4 and Microsoft’s Hyper-V R2 which is a must read for everybody who’s advising customers on hypervisors.

It’s not as extensive as the Enterprise hypervisor comparison we did earlier but it gives you a good image how both products relate to each other. To extend the picture I added a list of supported operating systems.

On a regular basis we have info sessions with our most important vendors.  Last week we had a session with HP to tell us more about virtualization in their hardware products. The session was especially targeted at Flex-10. Flex-10 is the way how HP breaks s a 2 x 10Gb Ethernet pipe into a flexible, easy to change, smaller Ethernet ports.

Why is this so important for us virtual friends? Of course it is a huge cost saver not only in hardware but also in management of the environment but the most important thing is that it opens up a lot of new virtual design opportunities.

.

One of the coolest things is that we now can make a design for up to 4 blade chassis with each physical 16 server blades and let’s say 320 virtual servers where all the traffic between the servers never leaves the blade chassis. It is all handled with the blade chassis. Also all of the vSphere traffic like VMotion and service console can be handled within the chassis at 10Gb speeds.

On the site www.vReference.com I came across a post announcing the “vSphere 4 reference card”. Wondering what this was I started reading the post.

It seems that Forbes Guthrie made a document containing hard limits for the vSphere 4 products. I found the list of items very wide and should come in handy when looking for limits of the vSphere 4 products.

The reference card is refreshed every now and then, so check out the site periodically. Or subscribe to the RSS feed of the site.

Hopefully this card can help you as future reference. I found it to be very helpful.

May 21th VMware released their new flagship product VMware vSphere 4.

With a new product comes a new set of courses, we (VMGuru.nl-crew) already attended the ‘What’s new in VMware vSphere 4‘ course given by Eric Sloof. And there’s also a new ‘VMware vSphere, Install & configure‘ course.

I now regularly get the question ‘The courses are nice but how do I become VCP on vSphere 4?‘

There are four different scenarios. Check this article on NTPro.nl to find out how you can become a VCP on vSphere 4.

The exam to upgrade your VCP to vSphere 4 (VCP4) will be available on August 1st.

If you are a VCP on VI3 and you have attended the beta program there is a chance to upgrade your certification long before August 1st by taking the beta exam. This exam will be available from June 29th but is not publicly available, candidates eligible for the beta exam will automatically be contacted by VMware and must be VCP3 certified and beta product users.

If you want to know more about the VCP on vSphere 4 exam, the blueprints can be found here.

Personally I would like to take the beta exam but Eric Sloof alerted me to a caveat in this scenario. To become a VMware Certified Instructor you will have to score 85% or more. If you take the beta exam the chance is greater you won’t make a score of 85% and you won’t be able to becme VCI. He also mentioned that it is difficult to re-take the exam to boost your score.

So I’m not sure yet. Become on of the first VCPs on vSphere 4 or have the opportunity to become a VCI? Dilemma!

I think I would like to be one of the first so I will be waiting for VMware’s invitation ……….

Last night I received an e-mail from Cisco thanking me for my work in the Nexus 1000V beta program and announcing the availability of the final product.

For those of you that don’t know the Cisco Nexus 1000V, it is a pure software implementation of a Cisco Nexus switch which can be used in vSphere 4. It resides on a server and integrates with the hypervisor to deliver VN-Link virtual machine-aware network services.

We are now 3 days from the day we, VMware enthusiasts, have all been waiting for. The general availability of vSphere 4! According to the information that VMware has published officially goes on sale on Thursday May 21st.

As VMware Premier Partner we received numerous e-mails from VMware with fact sheets, specifications and presentations on ‘What’s new in VMware vSphere 4‘, we even attended the ‘What’s new in VMware vSphere 4‘ course by Eric Sloof a few weeks ago. But so far customers have not been calling or e-mailing me to find out what’s new, were and when to purchase it. Don’t get me wrong, I thinks it’s a great new product with many new interesting features and improvements but our customers are not very interested yet.

I don’t now if this is because of the hypervisor battle going on, the economic situation, their great experience with ESX 3.5 or the release date close to the holiday season?

I’m curious to know what your thoughts are on this issue and if you are experiencing the same situation?

Today we attended the new ‘What’s new in VMware vSphere‘ 4 training and who better to get us up-to-date than Eric Sloof from NTPro.nl.

Eric already caught us on camera this morning while we were doing the labs so we thought we should return the favor .

Watch Eric Sloof share his thoughts on the first day of the training.

For those of you who have been following the launch of VMware’s new flagship vSphere 4 and are anxious to upgrade their virtual infrastructure, I ran into a great post on Mike DiPetrillo’s website.

Mike has posted four great video’s with the following scenario’s:

• Video 1 -VMware VirtualCenter Management Components
• Video 2 – VMware ESX Host Migration Methods
• Video 3 – Virtual Machine Upgrades (VMware Tools and Virtual Hardware)
• Video 4 – Implementing VMware vSphere Licensing

Interested? You can check out the videos here.

Today I, and two other colleagues, attended the vSphere 4 prodcut launch in Houten the Netherlands. The subject was Efficiency, control and Choice just as in the webcast from yesterday evening.

Jeremy presented the overall vSphere product and after a short break Ton Hermes presented the Technical track and Stef Koopman presented the Sales track. I attended the Technical track and Edwin and Alex attended the Sales track.

The information presented was not very new to us and probably not to you either as we posted an article on the news and new features yesterday.

The news were the features in the four versions of vSphere …….

This morning a message from John Troyer popped up on my TwitterFox telling me that on April 20th VMware  announced the general availability of their new flagship product, VMware vSphere 4. Finally after all our time beta testing and filling out reviews vSphere is coming!

PALO ALTO, CA, April 21, 2009 — VMware, Inc. (NYSE: VMW), the global leader in virtualization solutions from the desktop to the datacenter, today announced VMware vSphere™ 4, the industry’s first operating system for building the internal cloud, enabling the delivery of efficient, flexible and reliable IT as a service. With a wide range of groundbreaking new capabilities, VMware vSphere 4 brings cloud computing to enterprises in an evolutionary, non-disruptive way – delivering uncompromising control with greater efficiency while preserving customer choice.

As the complexity of IT environments has continued to increase over time, customers’ share of IT budgets are increasingly spent on simply trying to “keep the lights on.” With the promise of cloud computing, customers are eager to achieve the benefits, but struggle to see the path to getting there.  Leveraging VMware vSphere 4, customers can take pragmatic steps to achieve cloud computing within their own IT environments.  With these “internal” clouds, IT departments can dramatically simplify how computing is delivered in order to help decrease its cost and increase its flexibility, enabling IT to respond more rapidly to changing business requirements.

After many complaints from the community VMware finally gave in and renamed their next generation ESX, formerly known as vSphere, to vCloudOS. We at VMGuru.nl already complained at the end of 2008 about the new name and many other did the same. Some even claimed that VMware couldn’t have registered the name vSphere as it was owned by another company.

Despite the fact that VMware publically used vSphere as their new name for their virtual infrastructure at VMworld Europe 2009 in Cannes they now changed it.

According to VMware´s spokesman Faril Polos, ´The new name better reflects the role, the opportunities and VMware’s strategy for our line of Virtual Datacenter products.’

For more information visit the VMware website or look here.

VMware uses the name vSphere for their Virtualisation Infrastructure product also known as ESX. Here in Cannes in the hands on labs I have used the new interface and some of its nifty features. You have to get used to the new interface, but when you are used to it it works nicely and you can find your way around quickly. Did you have to search for some deep hidden options in the VI3 suite, here with the new look and feel around vSphere its almost effortless.

Yesterday I tried out the VMware vCenter Data Recovery Appliance in a hands on lab. It’s a disk-based backup and recovery solution that enables quick, simple and complete data protection for virtual machines. I didn’t have to load an agent on the virtual machines since vCenter Data Recovery has no knowledge of the guest operating system itself. After selecting a LUN as a destination for the backups, I marked some running virtual machines to be back upped.

Today we did our first Hands-on-Lab. Last year these labs were fully booked so we decided to hit the lab early this year.

This lab was based around the Cisco Nexus 1000v virtual switch, which brings back network administration to network administrators.

Erik did the Cisco Nexus 1000v lab today. Since we didn’t receive any beta material yet this is our first real experience with the new virtual switch by Cisco.The switch is based on NX-OS so network administrators can use it just like they configure their other switches.

Several blogs have already reported on this issue, the new version of VMware’s ESX product line will not be called VI4 or ESX(i)4 but VMware vSphere. When I read this I thought which idiot came up with that name? vSphere? What’s that? What is the link with ESX and virtualization? Are we going to run virtual machines in spheres in the future because the term ‘isolation’ was not clear enough? Does VMware need to join the buzzword-hype, like ‘bubble’ and ‘cloud’?

Apparently VMware employees where able to vote for a name for the new product and vSphere was the winner in this competition.
