As organizations find their server infrastructures become mostly virtualized and start virtualizing their desktops, they come to realize that vSphere alone is not enough to manage and troubleshoot this environment.  That's why you see so many ISVs offering solutions in this space, and why VMware has finally jumped into the fray with vCenter Operations.  I've been a big fan of vCOps ever since its release earlier this year.  It does a great job of boiling down all the available data points into an easy to understand format, while still providing the ability to quickly drill down during a performance problem.

Xangati is another vendor in this space that I find really impressive.  They are taking a different approach.  Their approach is to not necessarily boil everything down to über-simplicity, but to give you a more holistic vision of the entire environment, along with all the relevant data points.  They're doing this because of the inherent complexity of a virtualized infrastructure.  There are many moving parts that are all interrelated and constantly changing, and a hiccup in one subsystem can have major ramifications in another system.  They call this the "Performance Ripple Effect" (a term I found very interesting).

With their new release this week, they also now can look inside of the Windows guests using WMI and the PCoIP communications within VMware View thanks to their new partnership with Teradici.

If you have a medium or larger VMware environment, I'd highly recommend taking a look at both products.  Both offer free trial periods and can be really useful if you already have a performance problem you'd like to dig into. 

Today is the day folks!  At 6pm CDT (that's covers Chicago, Dallas & Kansas City, as well as Omaha, Des Moines and Bloomington, IL) the VMunderground crew will release 225 tickets for our Mother of All vBeers event at VMWorld 2011 in Las Vegas.  Those of you who have been to one of the previous five editions of this party know how much fun it's been in the past, but this year will be an epic party.  If you'll be at VMWorld this year in Vegas, you owe it to yourself to set the alarm on your phone for 5:55pm CDT and run to a computer.

Ticket will be made available here: wupaas2011.eventbrite.com

More detail about VMunderground and the party itself is here: www.vmunderground.com

But most importantly (because we couldn't do it without them), check out the companies willing to pay for all this awesomeness:

• Veeam
• HyperIP
• TrainSignal
• Nexenta
• BlueLock
• Panologic
• Xangati

I alluded to this in my previous post, but it seems that no one else has picked up on it yet, so I figured I might as well write up the first post on the subject.

People familiar with the VMware View Bundles know about a special license of vSphere that comes as part of the package, vSphere 4 for Desktops.  This is a CPU-unlimited edition of vSphere 4 that is EULA bound to only running desktop infrastructures (virtual desktops and brokers).  This helps to drastically drive down the price of a VDI deployment, which is one of the main hurdles to getting VDI implemented.

With the release of vSphere 5, VMware now has four enterprise editions (from the VMware website):

------

	
VMware vSphere Standard provides server consolidation and no planned downtime.
	
VMware vSphere Enterprise provides powerful & efficient resource management.
	
VMware vSphere Enterprise Plus provides policy-based datacenter automation.
	
VMware vSphere Desktop provides the platform to deploy desktop virtualization offering scalability, high availability, reliability and optimal performance for all your desktop workloads.

------

The last of these is the one to take note of.  Apparently the vSphere edition currently available with View 4 is going to be made available as it's own edition separate from View.  What's the advantage of this?

1. You won't have to pay the full price of vSphere Std/Ent/Ent+ or a View Bundle to host non-View VDI implementations (i.e. XenDesktop, vWorkspace) on vSphere.
2. No vRAM cap.
3. Enterprise Plus feature set.
   

This standalone vSphere edition does inherit one limitation from it's View parent: only desktiop infrastructures can be hosted on these hosts.  One difference it has is that the version included with View is licensed per concurrent connection, whereas the standalone version is licensed per powered on desktop VM.

I think this is a significant development.  I see, roughly, about half VDI implementations go XenDesktop, and a good portion of those still end up on vSphere.  I have advised customers to consider buying the View Enterprise Bundle to simply get the vSphere Desktop licensing if they are going to use vSphere as the hypervisor in a XenDesktop implementation (the View Bundle EULA is written to allow this currently). A separate vSphere Desktop edition allows for a much cleaner licensing discussion.

What's that you say?  "What's it going to cost?"  I suppose that is an important question.  The list price will be $65/VM, sold in bundles of 100 (so $6500 per 100).  Much cheaper than the current View Enterprise Bundle list price of $150/concurrent user (depending on your VDI concurrency).

There is no upgrade or license conversion to this edition.  It is only available as a net new license.

A bit more detail can be found on this VMware blog post (that just barely beat me to posting).

If you hadn't noticed, VMware announced vSphere 5 on 7/12.  The announcement was well handled and I enjoyed watching the first hour.  The follow-up sessions weren't working in my browser, so I wasn't able to attend any of those, but I ended up spending a lot of time on Twitter and VMware's sites looking into the new features and licenses.

There are two main topics I want to cover.  First I'll cover the new licensing scheme for vSphere 5, which has become a very hot topic of criticism for VMware.  Then I'll talk about some of the new features of this release.

Licensing

As part of the upgrade to vSphere5, customers will need to figure out a new licensing scheme.  A change in the licensing shouldn't come as a surprise, since core and processor speeds have taken out a major chunk of VMware's revenue stream from their core product, not to mention VMware's history of changing licensing with every release.

The new scheme continues the tradition of one license per socket, but now allows for unlimited cores in every edition and a new memory cap.  It's a lot more complicated than that though.  The cap is not for the amount of physical RAM in the host, but it's a cap on a new construct they call vRAM.  vRAM is the amount of RAM assigned collectively to the virtual machines.  The licenses will combine their vRAM caps at the vCenter level (or multiple vCenters when using Linked Mode) to create a pool that all VMs in the infrastructure can pull from.  One caveat is that different editions of vSphere (Standard, Enterprise and Enterprise Plus) will create different pools.  When architecting infrastructures, you'll need to now consider not only the number of sockets in all the hosts, but also the total amount of RAM utilized by all the VMs.

The vRAM caps layout like this:

Essentials, Essentials Plus & Standard - 24GB
Enterprise - 32GB
Enterprise Plus - 48GB

This cap ignited a fire storm on twitter, blogs, email lists and even the private vExpert forum over at the VMware Communities. The root of this storm is what appears to be an increase in licensing for larger environments.

I'm guilty of contributing to this storm.  But as a good community member, I wanted to back up my comments, so I started contacting my customers to get a handle on what the licensing changes will mean to them.  Based on my results, this will be problem for larger environments, but many of my customers don't fall into this category.  Working with real world numbers and theoretical numbers it looks like the vRAM cap based licensing will increase environments using 196GB or greater per host, environments with a large cluster of 128GB or greater per host or environments heavily overcommitted.  Of the customers I've pinged, only one of them is affected.  But I do have customers that are building clusters right now with hosts of 196GB, and this will be a concern for them.

My concerns with this change have lessened, but have not been eliminated.  The advantages of scaling up the hosts (the exact solution Cisco is betting on for UCS extended memory servers) has less advantage that it did in vSphere 4. The costs may still make sense to scale up a smaller number of hosts as opposed to buying additional hosts for a scale out solution, but those costs are way to variable for me to swing at right now.  The burden on partners like myself will be greater now to architect the number of hosts/CPUs and VMware licenses to create the cheapest solution based on the known facts.  In some cases, it may actually make sense to upgrade to Enterprise Plus to gain the higher vRAM cap. It is also a good push to minimize the RAM each VM is allocated.  If you're worried about having to buy additional licenses, I'd start my reducing the RAM allocation of your VMs first (VMware will happily talk to you about CapacityIQ).  An interesting new PowerShell script has been created to help analyze your situation.  Finally, don't be surprised if us partners become more pushy to do a capacity plan before making recommendations. :)

VMware is clearly making a push to more of a cloud mentality for it's licensing ("utility" computing in VMware's words).  I just don't think VMware's general customers are ready to manage their envrionment in that way.  I honestly don't have many issues with licensing this way, but it's hard to wrap your mind around it and the vRAM caps are most definitely too low.  It also completely underminds the overcommitment advantages VMware has touted as one of their biggest advantages over the "good enough" club (Microsoft Hyper-V and Citrix XenServer).

My final thought on licensing (for this post at least) is to point out one big irony.  Back when vSphere 4 was released, a firestorm was created due to VMware's planned elimination of the Enterprise tier.  They introduced the Advanced tier, but it wasn't enough to justify the huge jump in cost/features that Enterprise filled.  Customers and partners both screamed and convinced VMware to keep the Enterprise tier.  The irony: Advanced has been removed in vSphere 5 and those licenses will be converted to Enterprise.

New Features

Now for the good news:  vSphere 5 introduces a ton of great new features (another expectation we have from VMware during each major release).  Here's a quick rundown of my favorites:

• A vSphere Desktop edition - This was quietly added on the partner SKU list for non-View VDI implementations.  This provides a low cost hypervisor for XenDesktop implementations (a fairly common occurance).
• Storage DRS - Provides IOPS latency and disk space balancing across a grouping of datastores.
• vCenter Server Applicance - The long awaited Linux based vCenter Server.  It is delivered as an OVF and can quickly be brought online using an embedded database or an external DB2 or Oracle database.  It can also be integrated into AD.  It's not 100% feature parity with the Windows install, but a much welcomed step in the right direction.
• vSphere web client - Ability to access vSphere functionality from a web browser without installing the full vSphere client.  Though it is not 100% feature parity with the .NET vSphere client, it will be a great alternative when needing to complete a quick task while at a machine that doesn't have the client already installed.
• HA rewrite - Changes have been made to the HA product that eliminates the traditional primary/secondary issues.  They have also made enhancements to improve reliability and easier setup.
• Auto Deploy - Using PXE, you can boot your hosts across the network and apply configurations and host profiles to customize the host.
• VMFS 5 - A non-impactive upgrade (remember VMFS2->VMFS3?) will provide improved performance.  You can also create VMFS volumes greater than 2TB - 512 bytes.
• VM version 8 -The latest version of the VM hardware adds USB 3.0 and 3D graphics support.
• VAAI Thin Provisioning - More closely integrates thin provisioning to the array itself.

I’m most happy and pleased to announce my acceptance back into the vExpert community for yet another year.

It’s been a great program that I’ve had the honor to be involved in for all three years it’s existed.  It’s grown over those years and now includes some really great benefits.

Big thanks go out to John Troyer who runs the program and deals with all the weirdness we put him through.  I’d also like to extend a big “Thank You” to the anonymous board of voters that helped John filter through all the submissions for the award.  Finally I’ll recognize the leadership at VMware, particularly CTO Steve Herrod, for supporting this program.  It’s developed a strong community amongst ourselves that ultimately supports VMware from the roots of the grass and we all love it .

First I must start by apologizing to those of you who watchmy blog regularly for my lack of posts lately. Not that it really has affected your life in any negative way, but Istill feel bad since I view it as a commitment that I’ve failed to maintain.

Obviously writing for TechTarget has taken some of the steamout of this blog, but the thing that has really hurt the blog lately is mylatest project: writing and recording the VMwareView Administration Training video training series for TrainSignal.  This series is dedicated to the installation,configuration and management of VMware View. It also covers all the topics needed to study for VMware’s new VCA4-DTcertification.

I took the beta version of the VCA4-DT exam at VMware’sPartner Exchange conference back in February.  Afterwards, I was discussing it with TrainSignal’sDavid Davis and he mentioned theywere working on a video series aimed at the exam.  Since I’ve done a LOT with View in the lastthree years, I offered him any help they might need in building thatcourse.  No more than two weeks later, Ireceived a call from TrainSignal asking if I would be interested in putting thecourse together myself.  What an honor toget the entire thing tossed to you!

My biggest concern was the amount of time creating an 8-10hour video training series would take, but after discussions with my wife, wedecided it was a worthwhile endeavor, so I signed on the dotted line.

After almost 3 months of long nights and a few PTO days fromthe day job, the video is now off to the presses and will be officiallyreleased on July 6^th!  You can view a sample of the series here on YouTube. 

I’ve done it on Twitter already, but I want to send myspecial thanks to David Davisfor helping arrange this opportunity, MattElias for offering it to me and to Brian Green who had to wadethrough way more hours of video than I care to remember.

It was definitely a rewarding experience, one that I hope tobe invited back to do again.  If you getthe opportunity to view any of these videos, please let me know what you think.
