Defragmenting your CSV Windows 2012 R2 Style with Raxco Perfect Disk 13 SP2

When it comes to defragmenting CSV it seemed we took a step back when it comes to support from 3rd party vendors. While Windows provides for a great toolset to defragment a CSV it seemed to have disappeared form 3r party vendor software. Even from the really good Raxco Perfect disk. They did have support for this with Windows 2008 R2 and I even mentioned that in a blog.

If you need information on how to defragment a CSV in Windows 2012 R2, look no further.There is an absolutely fantastic blog post on the subject How to Run ChkDsk and Defrag on Cluster Shared Volumes in Windows Server 2012 R2, by Subhasish Bhattacharya one of the program managers in the Clustering and High Availability product group. He’s a great guy to talk shop to by the way if you ever get the opportunity to do so. One bizarre thing is that this must be the only place where PowerShell (Repair-ClusterSharedVolume cmdlet) is depreciated in lieu of chkdsk.

3rd party wise the release of Raxco Perfect Disk 13 SP2 brought back support for defragmenting CSV.

I don’t know why it took them so long but the support is here now. It looks like they struggled to get the CSVFS (the way CSV are now done since Windows Server 2012) supported. Whilst add it, they threw in support for ReFS by the way. This is the first time I’ve ever seen this. Any way it’s here and that’s good because I have a hard time accepting that any product (whatever it does) supports Hyper-V if it can’t handle CSV, not if you want to be taken seriously anyway. No CSV support equals = do not buy list in my book.

Here’s a screenshot of Perfect disk defragmenting away. One of the CSV LUNs in my lab is a SSD and the other a HDD.

Notice that in Global Settings you can tweak the behavior when defragmenting optimization of various drive types, including CSVFS but you just have to leave the default on unless you like manual labor or love PowerShell that much you can’t forgo any opportunity to use it Winking smile

image

Perfect disk cannot detect what kind of disks you have behind the CSV LUN so you might want to change the optimization method if you’re running SSD instead of HHD.

I’d love for Raxco to comment on this or point to some guidance.

What would also be beneficial to a lot of customers is guidance on defragmentation on the different auto-tiering storage arrays. That would make for a fine discussion I think.

Migrate A Windows 2003 RADIUS–IAS Server to Windows Server 2012 R2

Some days you walk into environments were legacy services that have been left running for 10 years as:

  1. They do what they need to do
  2. No one dares touch it
  3. Have been forgotten, yet they provide a much used service

Recently I had the honor of migrating IAS that was still running on Windows Server 2003 R2 x86, which was still there for reason 1. Fair enough but with W2K3 going it’s high time to replace it. The good news was it had already been virtualized (P2V) and is running on Hyper-V.

Since Windows 2008 the RADIUS service is provided by Network Policy Server (NPS) role. Note that they do not use SQL for logging.

Now in W2K3 there is no export/import functionality for the configuration in IAS. So are we stuck? Well no, a tool has been provided!

Install a brand new virtual machine with W2K12R2 and update it. Navigate to C:WindowsSysWOW64 folder and grab a copy of IasMigReader.exe.

image

Place IasMigReader.exe in the C:WindowsSystem32 path on the source W2K3 IAS server as that’s configured in the %path% environment variable and it will be available anywhere from the command prompt.

  • Open a elevated command prompt
  • Run IasMigReader.exe

image

  • Copy the resulting ias.txt file from the  C:WindowsSystem32IASfolder. Please keep this file secure it contains password. TIP: As a side effect you can migrate your RADIUS even if no one remembers the shared secrets and you now have them again Winking smile

image

Note: The good news is that in W2K12 (R2) the problem with IasMigReader.exe generating a bad parameter in ias.txt is fixed ((The EAP method is configured incorrectly during the migration process from a 32-bit or 64-bit version of Windows Server 2003 to Windows Server 2008 R2). So no need to mess around in there.

  • Copy the ias.tx file to a folder on your target NPS server & run the following command from an elevated prompt:

netsh nps import <path>ias.txt

image

  • Open the NPS MMC and check if this went well, normally you’ll have all your settings there.

image

When Network Policy Server (NPS) is a member of an Active Directory® Domain Services (AD DS) domain, NPS performs authentication by comparing user credentials that it receives from network access servers with the credentials that are stored for the user account in AD DS. In addition, NPS authorizes connection requests by using network policy and by checking user account dial-in properties in AD DS.

For NPS to have permission to access user account credentials and dial-in properties in AD DS, the server running NPS must be registered in AD DS.

Membership in Domain Admins , or equivalent, is the minimum required to complete this procedure.

  • All that’s left to do now is pointing the WAPs (or switches & other RADIUS Clients) to the new radius servers. On decent WAPs this is easy as either one of them acts as a controller or you have a dedicated controller device in place.
  • TIP: Most decent WAPS & switches will allow for 2 Radius servers to be configured. So if you want you can repeat this to create a second NPS server with the option of load balancing. This provides redundancy & load balancing very easily. Only in larger environments multiple NPS proxies pointing to a number of NPS servers make sense.Here’s a DELL PowerConnect W-AP105 (Aruba) example of this.

Is there longevity in Private & Hybrid Clouds?

This blog is just thinking out loud. Don’t get upset Smile

Private & hybrid clouds demand economies of scale or high value business

Let’s play devils advocate for a moment a look with a very critical eye at private & hybrid clouds. Many People are marketing, selling and buying private & hybrid clouds today. Some of us are building them ourselves, with or without help. Some of us even have good reasons to do so as it makes economical sense to do so. But for many that do it or consider doing it that might not be the case. It depends.

Why are so many marching to the beat of those drums? It’s being marketed as great, it’s being sold as what you need and that’s what makes money for many people. But one can say the same of Porsches, but chances are you’re not buying those as company cars. Well it’s perhaps a bit like VDI. If you have a use case that’s economically sound, design and implement it well, it will serve your needs. But it’s not for everyone as it can be expensive, complex & restrictive.

You want your cloud to be this:

AZurenice

Not this:

cloudnasty

To get great results you’ll need to do more than throw your money at vendors. So what’s the real motivation to do private/hybrid clouds for companies? If the answer is “well so many people are doing it, we can’t ignore it”. Well not doing something is not ignoring it, it’s a valid choice as well. And what others do isn’t relevant per definition. You need to know what you do where and why to make plans & choose technologies to achieve your goals. Think about what you do. When does a private/hybrid cloud make sense? How big do you need to be? What kind of delta should you have to make this worth while, i.e. how many VMs do you deploy per week? How many do you destroy each week?  What economies of scale must you have to make it wise? What kind of business? What are your pain points you’re trying to solve? What are you trying to achieve? Private clouds today are not void of complexity and there a are few abstraction layers that are at the quality/functionality level they need to be at.

My biggest concern here is that too many companies will build expensive, complexes private & hybrid clouds without ever seeing the return on investment. Not just because of the cost, complexity but also because they might not be very long lived for the use cases they have today. Many see these as transition models and they are great for that. The question is how good are you at transitioning? You don’t want to get stuck in that phase due to costs of complexity. What if the transition lasts to long and you complete it when public cloud has evolved into services that wipe away what the reasons your TCO/ROI was based on?

Note: as cloud means everything to every one you could call doing on premise & Office 365 + backup to the cloud also hybrid. So in that case Hybrid is a better fit for many more organizations.

Things are moving fast

Cloud offers are increasing at the speed of light and prices are dropping in free fall. While some say that’s a race to the bottom, it’s not. This is an all out battle which is raging to grab as much market share as possible. When the dust of this settles who’ll be left? Google, Amazon and Microsoft. They’re not loss leaders, they have a purpose and only they know the financial picture behind their solutions.

image

From there they’ll defend a fixed and entrenched position.  Where will that lead us? Stalemate and rising costs? Or a long term tug of ware where mutual assured bankruptcy will make sure prices won’t rise too much … until some game changing event that breaks it all open. For many people IAAS is still (too) expensive and non of the cloud vendors seem to run a profit, all this at ever lower prices. Sounds like a price hike will be in order once the market shares have been grabbed. But have people really calculated the cost of on premise? Can one compete? Or is the benefit of on premise worth the cost? Oh and I take on premise as being anything that even resembles racks in local or regional data centers running a cloud stack on it for you. Now I have to admit that in my region of the world most cloud hosters are not on a level of professionalism & scale like they are in the Nordics for example.

SAAS, PAAS, IAAS

That’s my order of preference actually. I think SAAS & PAAS are the areas where cloud really shines. IAAS can be a great solution for many needs but I don’t see it as ready yet a a whole sale replacement of on premise.  While many offerings in IAAS are not perfect yet and there are many blocking issues to be solved there is a lot of value in the cloud when you do it right for your needs. If you have a very modern and optimized IT infrastructure IAAS can feel like a step back right now but that will change in the right direction over the next 2 to 3 years I think. And as during that time frame you start using SAAS & PAAS more en more I which means improved IAAS will be able to cover (all?) your remaining needs better. Again, you need to things that deliver fast or you run high (financial) risks.

Intersecting fields of fire

In this race at light speed,which cloud vendor is best? If you want and need to have all bases covered I think it’s reasonably safe to say Microsoft holds the most complete port folio from IAAS, PAAS, SAAS & Cloud storage. They’re now throwing in MPLS networks (http://azure.microsoft.com/en-us/services/expressroute/)  to tie it into hybrid scenarios which should take last century VPN technology out of the picture. Some more standardization in network virtualization, flexibility and capabilities would be welcome as well. But in the end will it matter? People might choose based on possible use cases or capabilities but if you don’t need them that’s a moot point. They become commodities you buy from a few players, I just hope we like our cloud dealers a bit better than we do our energy and telecom providers. Nobody seems really happy with those. But as a buyer I like the idea of having options, as the saying goes “I’d rather have it and not need it than need it and don’t have it”.

Now MPLS s coming what else is missing? A storage gateway / proxy in IAAS

One of the biggest issues in airlifting the entire on premise infrastructure into the cloud is the legacy nature of the applications in combination with the high cost of IAAS (VHD) storage and the limitations compared to what you can do with VHDX on premise. That’s probably an artificial licensing decision bit what can you do? What we need to alleviate this is a REST based cloud gateway to present storage to legacy apps in IAAS while storing the data in Azure blob storage. It’s a bit of a cludge as we’’ just love the fact we can get rid of pass through, vISCSI, vFC thanks to (shared) VHDX. Why do I think we need a solution? Apps have a very long (too long?) live time and it would speed up cloud adoption big time. Just dropping the price for virtual disk storage would be the easiest path to go but I don’t see any indication of that.

The lure of being in the cloud is big but bandwidth & latency in combination with storage costs is keeping people from going there when it comes to so many “legacy” on premise applications. There is a fix. Put everything in the cloud where is is close together and where bandwidth and latency can become a none issue. We need affordable storage and a way for legacy apps to handle object based storage. The fact that the new StorSimple offering has an azure appliance doesn’t really help here as it’s tied to on premise and it’s iSCSI to the guest in IAAS. Not that great is it? For now it looks too much like on boarding to Azure for non MSFT shops and people who are way behind the herd in modern technologies. At least for the environment I work in. Physical server are there to host VMs, so no StorSimple. Other physical servers are point solutions (AD, Exchange or specialized software that needs more hardware access than virtualization can supply). Again, no StorSimple target.

I cloud, you cloud, we cloud

Building and maintaining a data center is loosing it’s economic edge fast. At least for now. I’m not saying all data center or even server rooms will disappear but they’ll reduce significantly. The economics of public cloud are to attractive to ignore. Private and hybrid clouds cost money on top of the cost of running a data center. So why would you? Sure, the cost of cloud isn’t cheap but there are other reasons to move:

  • Get rid of facility management of data centers and server rooms. It’s a big issue & cost.
  • Power/cooling needs. The big cloud players are rapidly becoming the only ones with a plan when it comes to developing an energy plan. Way more innovative & action driven then most governments. They’ll have way better deals than you’ll ever get.
  • Infrastructure costs. Storage, networking, compute, backup, DR, licensing … the entire life cycle of these cost a lot of money and require talent.
  • Personnel costs. Let’s face it. Talented people might be a companies most valuable resource in HRM speak, but in reality they’d love to get rid of a much of that talent as possible to maximize profits. The only reason they employ talent is because they have to.
  • The growth in compute & storage in the cloud is humongous. You’ll never keep up and compete at that level. It was said recently Moore’s law has been replaced by “Bezo’s law’’ http://gigaom.com/2014/04/19/moores-law-gives-way-to-bezoss-law/

I’m going to make a bold statement. If you want/need to do cloud, you should really seriously consider spending your money in public cloud and minimize your investment in private/hybrid clouds. Go as directly to the future and try to keep your private/hybrid stack as simple and cheap possible as a transition to the public cloud.  Leverage PowerShell, SMA and for example Azure automation to manage what you leave on premise. I have my doubts about the longevity of private/hybrid clouds for many organizations and a such investments should be “optimized” => cheap & easy to replace. So unless you have a real big business case for wanting to keep on premise and can make that economically feasible, it’s not your goal, it’s a transition tool. If you’re a huge enterprise, an agency involved in national security a hosting company or Switzerland you can ignore this advice Winking smile. But I see no one rushing to buy RackSpace?

Security, Privacy, Concentrated Power?

What about security, privacy, vendor lock in? You have to worry about that now as well, and you’re probably not that good at avoiding it on premise either. Switching from Oracle to SQL is not an easy feat.  Cloud companies will have a lot of power due to the information they distill form big (meta) data. On top of that they’re set to be the biggest providers of compute, energy & if they buy some telecoms companies  even of data communications. More and more power concentrated in ever less players. That’s not desirable, but it seems that’s how it will play out. The alternatives cost more and that determines most of all what happens. The economies are too good to ignore.

Government clouds to mitigate risk?

I now also see the call to build government clouds. Often at various levels. Well for decades now, bar some projects, a lot of their IT efforts have been slow, mediocre and expensive. 400$ to lift & place back some floor tiles. Having to buy a spool of 2km fibre channel if you need 80 meter. 5000$ to answer a question with yes or no, a VM that costs 750$ per month … (1000$ if you want a backup of the VM). 14 days to restore a VM from backup … abuse & money grabbing are rampant. Are these people going to do private cloud and compete? Are they any better at securing their infrastructure than Amazon? Is on premise encryption any better than in the cloud? And even if it is, it’s only until someone pulls a “Snowden”. And who’ll build ‘m? Where are the highly skilled, expert civil servants after decades of outsourcing leaving them at the mercy of 3rd parties? Are they going to buy them away in an era of cost cutting? And if they could, can they use them, do they have the organizational prowess to do so? So they’ll be build by the same pundits as before? Outsourcing to India would at least have been “the same mess for less”, while now it’s the same mess for more.

Sheep, lemmings, wolves & a smart CIO

I see way to little strategy building on this subject and to much “comfort” decisions being made that cost a lot of money and efforts delivering not enough competitive advantages. The smart CIO can avoid this an really deliver on “Your Cloud, Your Terms”. The others, well they’ll all play their role …

Just some food for thought. But I leave you with another musing. 100% cloud might be a great idea but it’s like leasing or renting. There are scenarios where ownership still makes since depending on the situation and business.

Shopaholic Organizations

There is a shocking addiction to trying to buy ones way out of problems. If the service desk process sucks then you buy a CRM package. If this doesn’t do what you hoped out of the box, have it customized. You don’t have 100% IT automation? You need to buy a CMDB! Need to track changes? Go ITIL & do ITLM/ITSM all over the board. Projects don’t respect their boundaries? Hire some PRINCE expertise. Can’t keep up with all the project & resource management? Buy a ERP and integrate it with the project management software you’ve been abusing. You have no clue what to do next? Hire management consultants! We have one for every flavor of management. Your employees suck? Hire consultants. Slow applications? Buy flash only storage and 40Gbps switches. Your employees are disengaged? Get a coach, buy a team building experience and a 5$ pizza discount coupon as an “atta boy”. Maybe you could even gamify the company to success? And if you feel all alone and misunderstood you can join all the peer groups & professional organizations you can find to play that same broken record to each other over and over again whilst hoping you catch a break to a better gig.

Whatever the problem you’re facing, there is a product to buy and help to be hired. Like a true addict you keep using more of the same in the hope it will work. Nice twist on what Einstein called the definition of insanity. Yet why do so many people think it will help, all evidence to the contrary?

The obsessive and compulsive need to buy stuff to fix or even solve problems, needs, lack of skills, knowledge and insights is staggering. Sure the world is full of people and companies that will gladly take your money. Why? Well that’s their business model. The only aim is to separate you from your money. They’ll tell you they understand you, that they’ve helped hundreds of people and businesses like you. So they’ll sell you whatever it is they sell and they couldn’t care less if you’re still around next year. Until perhaps the moment in 18 months they know they can sucker you again. The only line of defense you have against that is your own good judgment. It’s not that all of them their products or services have no value at all. The better vendors will even walk away from an engagement when it not mutually beneficial. But the core of the problem is that you are having issues and that’s your inability to deal with problems that cannot be solved by buying something. It’s very much like a shopaholic.

It’s a business model for someone

The idea that there is a an easy fix to solve the issues your facing and make sure you can shine as a successful leader instead of being stuck in your current mess is very temping one. There is always someone who understands this. Who’s ready to step up and deliver. Which would be great if it was not for a few simple rules:

  • A fool and his money are easily separated. And if not, as long as the money is good enough they’ll put in more effort.
  • Your problems are internal, they are caused by you and need to be fixed by you. Any addiction to whatever (products, services, consulting, coaching) are actually keeping you away from the solution.

image

  • You as a manager, perhaps even a leader, will have to step up. Be all you can be and if that is not enough step aside. Do the latter yourself before it’s done to you, it’s less messy that way.

Listen, when the money is gone, all that is left are your internal resources, if you’re lucky. Acting as if they don’t matter means they won’t be very engaged. All budgets are limited, but that doesn’t mean that you need to be a scrooge. It means you need to create and build a capable organization even when budgets are plentiful that can stand on its own feet. One that is able to analyze and decide independently what it needs to do and act on that. Spend your money there. Otherwise as soon as you run out, you lose all your capabilities to act. It’s like a ship without power, on top of not even not having a rudder. You’re a drift, floating between the sharks that bled you dry.

Also, if all your organization knows what to do is hire & buy everything from others it can easily replace it with a cheaper one that’s optimized that model needing 40% to 50% less employees & managers. Pure substitution play. Game over. Economics 101.

You need to get a clue, make it happen, you and your team, no one else.  But it has to start with you. If you need coaches, consultants, products just to get started you’re not going to make it.

Ouch, that hurt!

Deep down you know the painful truth. While it would indeed be great if you’d be able to hire a coach, consultant or buy service, product that can take away your pains it doesn’t work that way. You cannot purchase those magical bottles of pixie dust or unicorn tears that can put the struggles and headaches behind you allowing you to solely focus on enjoying a successful business and be forever bliss.

image

I could tell you that you’re in luck as I have a nice stash of pixie dust bottles I can use in a pinch and for a price. But that’s not it. It’s experience, knowledge, having to work and live with solutions, see the good, the bad and the ugly of both marketing, “marchitecture” in combination with grand and hopefully realistic visions of analysis & architects what’s need. The only thing this has in common with pixie dust is that is doesn’t come cheap or easy neither, but it does work Winking smile

Too many times solutions are nothing but rehashed marketing & sales pitches that succeed due to a lack of skill on both sides. All kinds of schemes are used to justify them. They don’t achieve much at all. These are often self-serving “quick fixes” to something that is as structural & often over-hyped, over complicated problem serving some people agendas.

So you spend your money and for a little while you experience the illusion that you’ve solved something. But like any addict, you, the shopaholic, will return hard and fast to reality. Poorer and sadly none the wiser. You coast from purchase to purchase never breaking this destructive pattern. You like to fool yourself into believing that you’re investing instead of spending money because you see so many successful companies buy the same products or services. It’s kind of painful and sad to watch. Some of you will blame the market, incompetent employees or dishonest vendors, lack of commitment, disobedience. While all these factors do exist and play their role it’s not the real cause of your woes. The environment you operate in is no different for you or competitors. Sure there might be a hobby business around, run by the son of a super-rich business tycoon but that’s a minority. No, the playing field is the same, so could it, however painful that thought, be you, that’s not made of the right stuff?

What if despite all your best efforts and even some pixie dust you still have issues that are killing your performance?  You can suck it up and BS your way out. Say that what you did is the best in the world and nothing more can be done. Hire consultants to audit whatever it is you want to audit (or whoever you want to put in their place if you’re really political), blame you predecessor, the lack of (upper) management vision or the current sun spots cycle. You can also really dive in and pint point where the issues are. But that’s hard, very hard. A lot harder than buying a vile of unicorn tears which seems the missing ingredient in any unrealistic project, overly ambitious architecture or design. It’s horribly difficult to obtain because it is scarce beyond imagination.

image

I’ll make you a deal. While I possess some flasks, they are the most expensive substance ever to come by. So if you require the tears of a unicorn, you’re going to need truck loads with money of large denomination kind.

But there are no unicorn tears. YOU will need to fix your problems. Forget about buying products, that’s in essence automation and optimization. If you do that to a problem you only make it bigger and worse faster. Forget about coaches and consultants, they’ll only enable you to move faster and more targeted if you know the goal, that is. They will not solve your problems. That’s your job.

Don’t try to improve things with tools and services until you really know what’s wrong. Look very deep, hard and honest at your company, your managerial results and your actions. If you only find you do things to save your own behind, cover your back and hopefully move ahead you’re not fit to lead anything at all and you’re a much a strategist as my hamster. But in defense of my hamster: he lacks any ambition.  As a leader / manager you should care a bit more. Action is needed, from you. Lip service is useless. Talk is cheap. Fear kills. Deflecting decisions and responsibility makes you lose all credibility. If you care, act like it. If you don’t care no one else will for sure. If you can’t be bothered to do the hard work, no one will. You can’t lead from behind.

So what needs to be done?

Stop what you’re doing right now. Observe, orient, decide, and act (OODA) and see the progress of intelligent decisions and watch how money invested differs in results so much from money spent. There is no substitute. You don’t need tools, coaches, taskforces, committees and services. Those are only for amplification, they are force multipliers and that’s great as long as you don’t apply them to your problems. Hard as it may sound, its (free) advise that you won’t get from a sales person. You cannot avoid your responsibilities.

The eyes of the world are upon you

You brought this on yourself. You stepped on the plate as a leader. So yes, your employees are watching and they don’t miss much what affects them. I know employees can act very entitled and be a major pain in the proverbial behinds, but this discussion isn’t about that. Do you want to know why they doubt you, don’t follow you, ignore or possibly even oppose you? Because you show no leadership and do not portray any sign of competence or insight. For the good of the company and themselves they do what they need to, with or without you. No one goes over the top anymore at the blow of the whistle. So don’t pull rank, instead try to become credible.
