VIRTUMANIA Episode 17: Hyper-V Dynamic Memory Is Not Over Commit
The VIRTUMANIA continues with Episode 17! Rick Vanover jumps in the co-host chair for me this episode. We are joined by special guests Ben Armstrong, Adam Fazio, and Brent Ozar. The following is the podcast summary:
VIRTUMANIA Podcast Episode 17 – Hyper-V Dynamic Memory Is Not Over Commit Hosted by Rich Brambley (@rbrambley) of VMETC with co host Rick Vanover (@rickvanover) of Rickatron.us. Guests include Ben Armstrong, Microsoft Virtualization Program Manager, (@virtualpcguy VirtualPCGuy Blog), Adam Fazio, Microsoft Consulting, (blog), and Brent Ozar (@brentO) of brentozar.com. This week’s show starts with some talk about the recent keynotes, demos, and sessions from the Microsoft TechEd 2010 conference in New Orleans, LA, but then quickly switches to an explanation of what the new Hyper-V Dynamic Memory feature really is, and more importantly, is not. Virtumania is an Infosmack Production.

VIRTUMANIA Episode 16: The One About vExperts and VMWorld
Our weekly podcast is usually a loose and casual conversation, but VIRTUMANIA Episode 16 was definitely "off the hip". Regular co-host Marc Farley is back, Rick Vanover joins us as always, and very special guests John Troyer and Eric Siebert round out a great discussion. The following is the podcast summary:
VIRTUMANIA Podcast Episode 16 – The One About vExperts And VMWorld. Rich Brambley (@rbrambley) of VMETC and Marc Farley (@3parfarley) of StorageRap.com are joined by regular Rick Vanover (@rickvanover) of RickVanover.com. Very special guests this week are VMware’s John Troyer (@jtroyer VMTN Roundtable Podcast) and Eric Seibert (@ericsiebert) of vpshere-land.com. The conversation covers everything from VMware’s 2010 vExpert program, hyping VMworld 2010, to social media tools and preferences. Although no “stretched analogy” was used in the actual episode this week, the spontaneous recording is almost like a cafe conversation from an episode of Friends. Thanks to Greg Knieriemen (@knieriemen) of Chi Corporation for this Infosmack Production.

Future vCenter And SRM Requirement For 64 bit OS Means More vCenter VMs
VMware engineer Michael White’s post 64 bit is almost here – are you ready? on the Uptime (VMware and Business Continuity) Blog foretells of the future 64 bit requirement of both vCenter and SRM (Site Recovery Manager). White writes:
“I wanted to remind everyone, of what I have already seen floating around the internet, but still important enough to remind. Our next release of SRM is going to require a 64 bit OS. This is the same as our next release of VC as it too will require a 64 bit host OS. This change is required to support the increased capabilities of our products. As we scale our products to match our customers needs, generally 1 – 2 years in advance of where they will need all the capabilities of a given product we have had to use a 64 bit OS. This will show itself in increased numbers in things like more simultaneous vSphere client connections.”
To me these new operating system (OS) requirements mean we will see even more instances of vCenter as a VM (virtual machine). It only seems logical that a least path of resistance is to virtualize the management server in order to upgrade, especially considering all have already invested in 64 bit hardware for their hypervisors if they decided to upgrade to vSphere 4 in the first place. To go a step further, I’m willing to argue that it will be more common for an IT Department to justify the cost of additional ESX hosts, even if only dedicated for management, then it will to deploy new servers for physical instances of vCenter.
The looming transition to a console-less ESXi eventually means more management virtual appliances in the future too. Solutions which will continue to need a ESX console or similar will have to substitute their own appliance to operate with ESXi. This means even more justification for additional ESX/ESXi hosts and thus greases the decision to virtualize vCenter as well. I expect to see management clusters of ESX hosts become more common in the future than even the use of management networks today.
ESX hosts have bigger and badder hardware now than ever before allowing for higher consolidation ratios and larger applications to easily run in virtual machines, but it will be interesting to see if the vCenter as a VM best practices change over time. I personally feel that continuing to separate the database from the virtualized vCenter will continue to be a smart choice. Running a separate, and even virtualized, SQL instance ensures not only better performance of vCenter as a VM but enhances DR scenarios. In fact, those that already have the vCenter database on a remote instance will likely have a safer upgrade to the 64 bit vCenter.
The new 64 bit requirements will no doubt make for an interesting migration scenario, and I’m sure we will see some positive and negative opinions. Let me know your thoughts on a 64 bit vCenter as a VM in the future!

What Is VAAI And What Does It Mean For Virtualization?
You’ve probably heard VMware virtualization and storage talk about VAAI (vStorage API for Array Integration. If you’ve listened to episode 4 of VIRTUMANIA or watched the recent video from the vExpert Panel session at the Carolina VMUG Summit then you’ve heard me talk about it with some of those most in the know on the topic. But what is VAAI exactly and how will it impact virtualization in the future?
Side note – I hate saying “V A A I”. IMO it’s quite a tongue twister. I have adopted saying “V double A I” because it is much easier to get out.
VAAI Introduced 2 years ago
Although it does not exist in vSphere 4.0 today, believe it or not VAAI was first introduced at VMworld 2008 when the vStorage API was announced.
New Capabilities Deliver Deeper Integration with Storage Partner Functionality
vStorage enables intelligent integration of storage products within the Virtual Datacenter OS through the new vStorage APIs.vStorage APIs deliver tight integration of advanced capabilities from storage partners with the Virtual Datacenter OS from VMware. vStorage APIs for array integration will enable customers to leverage array-based capabilities, such as snapshots, provisioning, replication and restore, directly with individual virtual machines in conjunction with the clustering and pooling capabilities of VMware Infrastructure. vStorage APIs for multi-pathing will provide customers the ability to integrate advanced load balancing capabilities provided by leading partners’ multi-pathing software with their virtual environment.
If you are like me you were probably so overwhelmed by the news of the VCD-OS (That’s what VMware was calling the hybrid Cloud at the time … I guess?) that you missed (or were not capable or ready to comprehend) how complete of a strategy already existed for building Infrastructure as a service (IaaS) with the vStorage API. For me, looking back 2 years later it is amazing to me it was all there – at least in concept.
Don’t confuse VADP and VAAI
VAAI is only one part of the vStorage API. VADP (vStorage API for Data Protection) is another, but the these two seem to have been easily confused lately. VADP is
Carolina VMUG Summit 2010 vExpert Panel Video
David Davis (@davidmdavis vmwarevideos.com) recorded the 2:30pm vExpert Panel session from the recent Carolina VMware User Group (VMUG) Summit 2010. The session occurred on Friday June 11, 2010 in the Charlotte Convention Center and featured the following vExperts:
@sakacc Chad Sakac |
@vstewed Vaughn Stewart |
@scott_lowe Scott Lowe |
@mike_laverick Mike Laverick |
I was lucky enough to get to moderate the discussion, and along with excellent help in the form of several questions from the VMUG crowd (my co host for the event), I am extremely pleased with the conversation that resulted. We touched on VCE vBlock architecture, Secure Multi Tenancy, vStorage API for Array Integration, FCoE, and a few other virtualization related storage topics
in the 60 minutes we were given. In fact, the end result turned out much like a live version of both the Virtumania and Infosmack podcasts.
One of my personal goals for this session was that the everyone in the audience did not have be storage gurus in order to get benefits from listening. I’m proud to say that I feel we achieved this goal, and so I am embedding Davis’ video below so more VI admins can tune in to what these guys have to say about the future of storage and virtualization!
VIRTUMANIA Episode 15: Fishing For Virtual Desktops
Episode 15 of VIRTUMANIA features another conversation about VDI! As usual, Rick Vanover joins us as our show regular. Greg Knieriemen substitutes for Marc Farley as the co-host, and all three of us are honored to have Ron Oglesby as our special guest. The following is the podcast summary:
VIRTUMANIA Podcast Episode 15 – Fishing For Virtual Desktops. Hosted by Rich Brambley (@rbrambley) of VMETC and Greg Knieriemen (@knieriemen) with guests and Rick Vanover (@rickvanover) of RickVanover.com and Ron Oglesby (@ronoglesby) Chief Solution Architect at Unidesk. Unlike our previous VDI Plumber Crack episode where we looked at server infrastructure, this time the focus is on the end user side of virtual desktops. Just like in fishing there is a “tackle box” of choices for provisioning, managing and supporting user images and applications, and virtualization admins have to be careful not to snag their VDI project in the weeds of end point connection devices. Virtumania is a Infosmack Production.

Live Coverage From TechEd 2010 – Tuesday
I’m starting to get the hang of using Cover It Live (CiL) at a conference. I’m still working out whether using an iPhone/iTouch/iPad/Blackberry/Browser is the best way to update when mobile. I added some 30 second audio clips from @johnobeto, @cxi, @vmdoug, and myself in yesterday’s CiL session. Did you notice? I also pulled in some of @vmdoug’s Qik videos captured from his new HTC EVO.
Here’s my favorite Qik video from yesterday
I’ll probably do more of the same stuff throughout day 2 of TechEd 2010.
NEWSFLASH: For special and in depth conference coverage I am adding @HyperVBear to the stream of auto tweets. I suggest we all follow him closely for the rest of the week
You can replay yesterday’s CiL session here.
