So this conversation came up the other day, basically, “Hey, isn’t there a way to convert Std to Ent in one command?” Some might say, “No, you must re-install of your hosts and as part of that rebuild process I will charge you 1 million dollars in Consulting! MUAHHAHAHA!” But, no. The answer is. YES YOU CAN! And so I don’t have to go hunting to find this at some point in the future… here is all the citing evidence to refer back to ;)
Thanks to our dear friend, Jim Millard @millardjk – It’s as easy as seen in this tweet!
While this may not be the most authoritative source on the subject… if it solves for your problem, then BAM! And if not… well, we can track down those other scenarios! Unfortunately… I don’t have any Std versions to actually need to upgrade to Ent at the moment to screenshot through! But hopefully you find this useful.. eventually when I’m in that situation needing to use the cmd, I’ll look back upon this and give this a whirl! :) Enjoy!
From 2001 until 2006 I would regularly do presentations on OMG THERE’S FREE TRAINING OUT THERE WHY AREN’T YOU USING IT. Which even culminated in the release of a Technical Offerings training deck as noted in this blog post I published in 2006 (Yes, Seriously, in 2006) Well, guess what. A lot of that data is STILL highly relevant even today! So… Let’s get started! :)
Kicking off the realm of training videos I’d like to highlight our good friends at Microsoft with their release of the Microsoft Virtual Academy!
The MVA has a LOAD and I mean a serious LOAD of information, from Training Videos, Courses, Tutorials, Walkthroughs, even Tests and points and contests to increase not only the ‘fun factor’ but provide additional context in your education. For those of you VMwarriors out there who will discard this and say BLAH, SHOW ME THE VMware STUFF. I even did a little search for VMware in the “Quick Search” button and lo and behold lookie at the results!
So whether you are a rockstar, a seasoned professional or someone looking to get started and want to know where to get some good and valuable information without spending hours and $$$ in a classroom, this is definitely an excellent way to get started, so jump on in!
BUT WAIT, THERE’S MORE FROM MICROSOFT?!?!
I know some of you are fighting the constant battle of “Damnit, can I attend Microsoft TechEd or not…” And with TechEd 2013 going to be in New Orleans I cannot blame you in the LEAST! But for those of you who just truly cannot find the time, the ability and are able to get away… something you should know.
ALL MICROSOFT TECHED CONTENT IS AVAILABLE FREE WHETHER YOU ATTEND OR NOT.
Yea. Seriously. It is. It actually has been for like the last… Oh I don’t know… since 2004 I believe? And all of that past-content since they started posting and making it available online has been posted online. For some reason I’m only able to find the 2012 content and the 2011 Archive but who really needs access to material on product versions which may not even exist or are supported anymore, if you truly need that let me know and I’ll find the link!
A lot of you are familiar with TrainSignal and the loads of great content they create, produce and respectively sell out there (You can get access to their paid training video series and content on their website, Trainsignal.com) But when I reached out to their President asking, “Hey, you have any freeeeeee stuff!?!?!?” He pointed me over by here! So here is a whole bunch of videos freeeeeeeeeeeee of charge! And of course, don’t hesitate to check out the amazing content produced by the likes of Scott Lowe and David Davis and others!
Ya know… as an example here! :)
That should get you going on quite a load of stuff from Microsoft, to VMware, to Citrix and Cisco and beyond! But let’s drill down a bit into VMware now…
When it comes to VMware there are loads and loads (and loads) of information in the world, and often we never really know where to start… Well, here is a place to start and it’s home is in YouTube!
Yea, that’s lame right? I mean on YouTube there’s like a dozen channels?!?! Well, there are. Just go and use them. BAM, and BOOYAH.
VMworld Presentations are FREE TOO LIKE TECHED?!?!?
Well, no. Not exactly. Sorry! Although this last year VMUG Advantage did have a brief offer for free access to the VMworld content if you signed up for that… I’m unable to find any data on it at the moment, so that may have expired, but it’s still worth checking out!
SHOW ME THE LABS BABY!
You asked for Labs and here they are! More labs than you can shake a stick at!
Err, okay, maybe that was a little too literal! Let’s get on with our labs though!
FREE Hands On Labs from Microsoft!
The thing about Microsoft is… for 8+ years they’ve had FREE access to all of their products in a Try-Before-You-Buy model where you can DOWNLOAD any Product and play with it (okay, seriously that’s been around for going on 20 years) but they also instituted the Hands On Labs where the lab environments would BUILD themselves, provide you with a Lab guide to follow (or ignore) and learn and play with it that way. Not to mention all of the content they’d have in the Hands on Labs at TechEd would be POSTED and made available for you to go in and learn, explore and beyond!
This isn’t something new, it’s been around FOREVER, Here are links to where you can access it (as it’s actually available in several places).
Disclaimer: When I wanted to test something out, I’d spin up a lab which was designed to ‘best practice’ and go in and do whatever I wanted, I mean it was a lab environment available in minutes. Why not?
Interesting Fact, some of the types of labs and solutions available out there which you can play and learn from:
How to setup a product from scratch, like Sharepoint, Microsoft Exchange, SQL
How to MIGRATE a product from one version to another (like those products mentioned above and more)
How to Develop in a language like C#, Visual Studio, Azure, PowerShell and more
How to do other advanced types of things
Alllllllllllll the labs that were available at TechEd, so you know what that means… and if not, check it out!
You can find TechEd Labs in the Additional Content section here with this flask icon next to it!
Here at the MSEvents site there are a number of Virtual Labs on the “Virtual Labs” tab to choose and play from!
So if for a minute you thought this was going to be easy, or a single click site with all the answers. HAH.
FREE HANDS ON LABS FROM VMware?!??!
Well, not exactly.. I mean, sort of, kind of… but, well, let me explain. VMware recently announced “Project Nee” my dear friend Simon Seagrave talks about about it here at his blog. But ultimately, what Project Nee is intended to be is… VMware Hands On Labs publicly available online. However it is still in Beta at the moment. You can follow details of the VMware Hands On Labs by going here to the VMware Hands On Labs community!
Some additional places not even mentioned but you should check out, and all of the cited links for easy access and consumption:
So hopefully those of you out there who are looking to stay relevant, continue educating yourselves, maybe even heading down the certification track and whatnot will find this of benefit. I won’t lie to you, I’ve used these resources countless times over the years and I encourage others to. If you have any other sites to suggest, toss em into the comment section… This is an epic resources to reference from here until well.. until I write another one ;)
Hey everyone out there! I hope this finds you well and your holidays are off to a festive start. I find no better gift to you within the community than the motherlode and brainshare of information I’ve collected, assumed, and delivered throughout the years and even a rare ‘sighting’ of my own delivery of said material in case there is ever anything you’re wondering about the what, the where and so forth!
A little bit about this source material; The emphasis and focus on this is intended to be around virtualizing Exchange and SQL. And while some of you hardcore VMware zealots expect me to only discuss VMware it does take into heavy consideration and discuss the materials at hand on how to go about addressing this within the body of work that is Microsoft Hyper-V as well – So happy holidays to all virtualization! :)
To start I’d like to focus on my most recent delivery of this presentation material for our good friends at Windows IT Pro, Power IT Pro, and more specifically the instance of the discussion was with VM Tech Pro!
There by clicking on the handy dandy image, or even by this embedded link you will have access to the live presentation I delivered for the folks over by there and the some ~130 or so attendees who were on the line (submitting questions, so on and so forth). As most of you know this is something I’m particularly passionate about (Virtualization, Best Practices, Mission Critical Apps) all of that, and I do love to share my body of work to help make your day to day jobs even easier. I definitely encourage you to go through the link to check out the live version of events (slides can only tell so much of the story, and I share a lot of stories not reflected directly in the slides) but I also encourage you to check out the links below which will have the original source material and SPEAKER NOTES OMG THE SPEAKER NOTES! Those are filled with every ounce of material you need to help make your case and continue to make your case when it comes to virtualizing and driving your story home; it’s something you won’t regret having on hand. :)
I do encourage you to use this material to help make your case, if you’re going to publicly share the slides or use them in your own source (as many have done) I appreciate a reference or just letting me know (sometimes I update material and I’d hate for you not to have the latest material :))
Also anyone who wishes to contribute back into this living body of work, don’t hesitate to in the comments. We’re only as good as our information and any chance to improve that I’ll be sure to reference back to you as well! Thanks, and here is the rest of it! :)
Hi guys! You’ve seen me produce videos in the past I’m sure, although it is not that often that *I* am actually IN the videos where you can see me, if even for a moment. (You let me know if you like that, or not ;))
Through a series of events, I ended up recording this video. For your reference: This IS a first draft, in an infinite style of regularly updating my style for delivery. [This was done using a little camera and a tiny mount on not a whole lot of space on a whiteboard… if I went Pro for the next one… you’ll be all OMFG :)]
Initially, I had drawn up some notes of how I’d present this.. so in the effort of WTF and Full disclosure (You know me all too well ;)) These are those preliminary whiteboard/notes.
I did have some other pictures which showed bits and pieces.. but I’m sure you get the gist of it! So what exactly am I saying with this video, with these whiteboards.. with this.. you know, whatever it is I’m doing here. :)
Three things actually. One of the cool things about the VNX is that it provides you with:
Ease of Use – With simplicity of management using Unisphere, vCenter Integration, Single Pane for all arrays
Maximum Efficiency – With FAST-VP, You can go Thin, and use the right tier at the right time with auto-tiering
Consistent Performance – The magic of EFDs, QOS, FAST Cache, Wide-Striping, Consolidate and guarantee SLAs
I know what you’re saying “OMFG CHRISTOPHER, ARE YOU IN MARKETING?”No. And I usually stand by that, because I get things done ;). Yes, I intentionally chose fitting points which happen to coincide with the acronym EMC, you know why? Because for one thing it’s easier to remember. :) Not to mention, things should truly be easy to work with, and enjoyable; all the while providing an accurate picture of the story at hand!
Look forward to some future series where I actually go into the guts of the system and show you (from my perspective) the how’s and the why’s of these things [Time permitting ofcourse ;)]
So, for now, I leave you with this video. Take it with a grain of salt, it IS a first-draft cutting room floor version. As soon as I get my new mbp (April 1st?!) You should see some far better *Perhaps Annoying* videos coming from me ;)
And I know that some of you love me in videos sometimes… so for those of you who want to see me unplugged in an off-the-cuff impromptu interview (No, I’m not drunk), here is the infamous “I’m CXI, I’m from the Internets!” video!
I hope you enjoyed that. Now, I’d love to hear your feedback. Where you say “Wow, I never thought of it that way” Or, “OMG You’re a total tool!” Yea, I’m game for either of those – Whatever you have to offer up, constructive or otherwise!
Oh, and I also submitted this for an internal contest (Which if I win.. will give me a sweet wrap-around terrace suite at EMC World [Yes, you can all come hang out in my room ;)] So, support away in every way possible! :)
Watch this space for more stupidity, err I mean great content in the future!
Hey guys, the other day I was having a conversation with a friend of mine that went something like this.
How did this all start you might say?!? Well, contrary to popular belief, I am a STAUNCH NetApp FUD dispeller. What that means is, if I hear something said about NetApp by a competitor, peer, partner or customer which I feel is incorrect or just sounds interesting; I task it upon myself to prove/disprove it because well frankly… People still hit me up with NetApp questions all the time :) (And I’d like to make sure I’m supplying them with the most accurate and reflective data! – yea that’s it, and it has nothing to do with how much of a geek I am.. :))
Well, in the defense of the video it didn’t go EXACTLY like that. Here is a little background on how we got to where that video is today :) I recently overheard someone say the following:
What I hear over and over is that dedupe rates when using VMware deteriorate over time
And my first response was “nuh uh!”, Well, maybe not my FIRST response.. but quickly followed by; “Let me try and get some foundational data” because you know me… I like to blog about things and as a result collect way too much data to try to validate and understand and effectively say whatever I say accurately :)
The first thing I did was engage several former NetApp folks who are as agnostic and objective as I am to get their thoughts on the matter (we were on the same page!) – Data collection time!
For Data Collection… I talked to some good friends of mine regarding how their Dedupe savings have been over time because they were so excited when we first enabled it in the first place (And I was excited for them!) This is where I learned some… frankly disturbing things (I did talk to numerous guys named Mike interestingly enough, and on the whole all of those who I talked with and their data they shared with me reflected similar findings)
Disturbing things learned!
Yea I’ve heard all the jibber jabber before usually touted as FUD that NetApp systems will deteriorate over time in general (whether it be Performance, whether it be Space Savings) etc etc.
Well some of the disturbing things learned actually coming from the field on real systems protecting real production data was:
Space Savings are GREAT, and will be absolutely amazing in the beginning! 70-90% is common… in the beginning. (Call this the POC and the burn-in period)
As that data starts to ‘change’ ever so slightly as you would expect your data to change (not sit static and RO) you’ll see your savings start to decrease, as much as 45% over a year
This figure is not NetApp’s fault. Virtual machines (mainly what we’re discussing here) are not designed to stay uniformly the same no matter what in accordance to 4k blocks, so the very fact that they change is absolutely normal so this loss isn’t a catastrophe, it’s a fact of the longevity of data.
Virtual Machine data which is optimal for deduplication typically amounts to 1-5% of the total storage in the datacenter. In fact if we want to lie to ourselves or we have a specific use-case, we can pretend that it’s upwards of 10%, but not much more than that. And this basically accounts for Operating System, Disk Image, blah blah blah – the normal type of data that you would dedupe in the first place.
I found that particularly disturbing because after reviewing the data from these numerous environments… I had the impression VMware data would account for much more! I saw a 50TB SAN only have ~2TB of data residing in Data stores and of that only 23% of it was deduplicating (I was shocked!)
I was further shocked that when reviewing the data that over the course of a year on a 60TB SAN, this customer only found 12TB of data they could justify running the dedupe process against and of that they were seeing less than 3TB of ‘duplicate data’ coming in around 18% space savings over that 12TB. The interesting bit is that the other 48TB of data just continued on un-affected by dedupe. (Yes, I asked why don’t they try to dedupe it… and they did in the lab and, well it never made it into production)
At this point, I was even more so concerned. Concerned whether there was some truth to this whole NetApp starts really high in the beginning (Performance/IO way up there, certain datasets will have amazing dedupe ratios to start) etc. and then starts to drop off considerably over time, while the EMC equivalent system performs consistently the entire time.
Warning! Warning Will Robinson!
This is usually where klaxons and red lights would normally go off in my head. If what my good friends (and customers) are telling me is accurate, it is that not only will my performance degrade just by merely using the system, but my space efficiency will deteriorate over time as well. Sure we’ll get some deduplication, no doubt about that! But the long term benefit isn’t any better than compression(as a friend of mine had commented on this whole ordeal) With the many ways of trying to look at this and understand I discussed it with my friend Scott who had the following analogy and example to cite with this:
The issue that I’ve seen is this:
Since a VMDK is a container file, the nature of the data is a little different than a standard file like a word doc for example.
Normally, if you take a standard windows C: – like on your laptop, every file is stored as 4K blocks. However, unless the file is exactly divisible by 4K (which is rare), the last block has just a little bit of waste in it. Doesn’t matter if this is a word doc, a PowerPoint, or a .dll in the \windows\system32 directory, they all have a little bit of waste at the end of that last block.
When converted to a VMDK file, the files are all smashed together because inside the container file, we don’t have to keep that 4K boundary. Kind of like sliding a bunch of books together on a book shelf eliminating the wasted space. Now this is one of the cool things about VMware that makes the virtual disk more space efficient than a physical disk – so this is a good thing.
So, when you have a VMDK and you clone it – let’s say create 100 copies and then do a block based dedupe – you’ll get a 99% dedupe rate across those virtual disks. That’s great – initially. Netapp tends to calculate this “savings” into their proposals and tell customers that require 10TB of storage, that they can just buy 5TB and dedupe and then they’ll have plenty of space.
What happens is, that after buying ½ the storage they really needed the dedupe rate starts to break down. Here’s why:
When you start running the VMs and adding things like service packs or patches for example – well that process doesn’t always add files to the end of the vmdk. It often deletes files from the middle, beginning, end and then replaces them with other files etc. What happens then is that the bits shift a little to the left and the right – breaking the block boundaries. Imagine adding and removing books of different sizes from the shelf and making sure there’s no wasted space between them.
If you did a file per file scan on the virtual disk (Say a windows C: drive), you might have exactly the same data within the vmdk, however since the blocks don’t line up, the block based dedupe which is fixed at 4K sees different data and therefore the dedupe rate breaks down.
A sliding window technology (like what Avamar does ) would solve this problem, but today ASIS is fixed at 4K.
If you have particular thoughts about what Scott shared there, feel free to comment and I’ll make sure he reads this as well; but this raises some interesting questions.
We’ve covered numerous things in here, and I’ve done everything I can to avoid discussing the guarantees I feel like I’ve talked about to death (linked below) so addressing what we’ve discussed:
I’m seeing on average 20% of a customers data which merits deduping and of that I’m seeing anywhere from 10-20% space saved across that 20%
Translation: 100TB of data, 20TB is worth deduping reclaiming about 4TB of space in total; thus on this conservative estimate you’d get about 4-5% space saved!
Translation: When you have a 20TB data warehouse and you go to dedupe it (You won’t) you’ll see no space gained, with a 100% cost across it.
With the EMC Unified Storage Guarantee, that same 20TB data warehouse will be covered by the 20% more efficient guarantee (Well, EVERY data type is covered without caveat) [It’s almost like it’s a shill, but it really bears repeating because frankly this is earth shattering and worth discussing with your TC or whoever]
For more great information on EMC’s 20% Unified Storage Guarantee – check out these links (and other articles I’ve written on the subject as well!)
I won’t subject you to it, especially because it is over 7 minutes long, but here is a semi funny (my family does NOT find it funny!) video about EMCs Unified Storage Guarantee and making a comparison to NetApp’s Guarantee. Various comments included in the description of the video – Don’t worry if you never watch it… I won’t hold it against you ;)
Be safe out there, the data jungle is a vicious one! If you need any help driving truth out of your EMC or NetApp folks feel free to reach out and I’ll do what I can :)
