Microsoft re-releases Exchange 2010 Service Pack 1 Update Rollup 3 (V3)

Due to an issue with Blackberry devices Exchange Server 2010 SP1 Update Rollup 3 was withdrawn on March 14th. See my blog on this here.

The issue was identified and fixed so now there is a new release. My environment doe not use Blackberries so we were not impacted, We had already deployed RU3 so all we have to do is apply the current release over that one and we’re good to go.

It’s a good thing it’s back available since if bring back UDP support which is a much asked and need feature for Outlook 2003 and it also fixed the DAG copy GUI bug introduced  with SP1  (September 2010) where you could see and thus mange the copies anymore with EMC.

So all in all good news and we can all move ahead now.

Microsoft iSCSI Software Target 3.3 for Windows Server 2008 R2 available for public download

As TechNet subscribers, we had access to Windows Storage Server 2008 with Microsoft iSCSI Software Target 3.2  (also see Jose Barreto’s blog on this here). That was sweet but for one little issue. This SKU cannot be a Hyper-V Host. In order not to lose a physical host in the lab you could edit the MSI installer from the Windows Storage Server 2008 install media where you would delete the SKU check. Problem solved but not very legal so nobody ever did that.  You can install Windows Storage Server in a VM for the lab I know but that becoming very SkyNet like … Virtual servers providing virtual storage for virtual servers … and while a good option to have I like to have a hardware host.

Bring Windows Storage Server 2008 R2 along and Microsoft decided that we could have the iSCSI Software Target 3.3 software without constraints, except that you needed a TechNet/MSDN subscription, to install on W2K8R2. This is the one I’m running in my labs at the moment installed on a Physical Windows Server 2008 R2 Enterprise edition that also is a Hyper-V host. This provides all my iSCSI storage to both physical and virtual clusters. I used it to test MelioFS with FileScaler recently with a 2 node virtual cluster.

Today, Jose Barreto blogged about the public release of iSCSI Software Target 3.3 for Windows Server 2008 R2. This is very good news as now everyone has access to an iSCSI target for labs, testing, POCs, and even production. Thank you, Microsoft. Now with some luck, we could get some SMI-S support for it with SCVMM2012? Please?

If you need some help, Jose Barreto has a bunch of blog posts on configuring the iSCSI target, so I suggest you check out his site. As an added benefit, Microsoft iSCSI Software Target 3.3 setup & configuration is scriptable using PowerShell.

KB2230887 Hotfix for Dynamic Memory with Windows 2008 Standard & Web edition does not apply to without Hyper-V editions?

As my readers all know by now, since I blogged about this here, you need to install an update/hotfix for Hyper-v Dynamic Memory to work with Windows 2008 Standard & Web edition. You can find more information here:  Hyper-V Dynamic Memory does not work on a Windows Server 2008 Standard Edition or Windows Web Server 2008 virtual machine (VM)

UPDATE 2011/06/23: Microsoft released the hotfix based on end-user feedback and you can download version 2 that works on all SKUs now http://support.microsoft.com/kb/2230887 (v2).

The cause is that on these versions of the operating systems the the required memory enlightenment is supported. After installing the hotfix (or SP1 in the case of Windows 2008 R2) memory addition enlightenment is available on these SKU and your good to go.

But recently I ran into an issue. One virtual machine guest on a Windows 2008 R2 SP1 cluster that is running the Windows 2008 Standard edition without Hyper-V SKU, x86 the standalone installer for Windows6.0-KB2230887-x86 throws following warning:


Windows Update Standalone Installer


The update does not apply to your system


OK


That’s a bit strange. As you can see the hotfix has not been installed. And why would I need the with Hyper-V SKU to use dynamic memory with this guest?

I installed the same hotfix without any issue on several Windows 2008 Standard Edition (the SKU with Hyper-V)  guests. So what is going on here? What exactly is different about the without Hyper-V SKU?  Note that Windows 2008 R2 no longer has such a SKU.  Microsoft states that it is an SKU for people who don’t need virtualization. Well as they installed it as a guest virtual machine they chose this version and now what? No hotfix for dynamic memory as a guest?

There is a TechNet forum discussion going on here where they have this issue and I asked them to check what SKU it was happening on. Bingo! It’s on the Windows 2008 Standard without Hyper-V version!

I don’t expect any Hyper-V functionality or management tools but I do expect to get the hotfix to enable Dynamic Memory in guests with this SKU, just like we get any other update that is relevant to Hyper-V, for example, upgraded Integration Services. I’m going to ping a Microsoft contact on this one and see if they can help with this. And in case you’re wondering SKU = Stock Keeping Unit.

Private Clouds, Hybrid Clouds & Public Clouds

Now that I’m thinking of and working more and more towards a concept that might be described as a hybrid cloud using tools and technologies that should facilitate this (Azure, Virtual Machine Manager 2012, System Center vNext, Hyper-V vNext) I get to think about what cloud means, is and could or might become. In the end it is nothing more or less than utility computing based on standard components to deliver commodity services. What you do with those and how determines the success of your endeavors. After all not all devices run by electricity where brilliant and successful. Why is this important to notice? Well people tend to get involved in silly discussion of my cloud is better than yours. And to confuse things even more in between all those discussions vendors are fighting about what constitutes the best technology (hardware & software) for building one. That can be fun, but it has little to do with the value of the cloud as a concept. Now where do private clouds a hybrid clouds fit in? Is the private cloud and the hybrid cloud something temporary, a facilitator towards a “true” public cloud? Or is this just the case for the private cloud?

If you concur that not all IT is the same, not all organizations are the same and not all IT is or will become a commodity one could state that the hybrid cloud has a more permanent character. It will aid having a unified, holistic way to manage it all. Multiple environments with separate management are less attractive as that incurs overhead in costs and perhaps even skills.

But what about that private cloud? Let’s face it. Most (none) of us will ever be able to get the share volume en thus the economy of scale for cost, pricing, redundancy or flexibility as the public cloud. If we can, that would mean the public cloud vendors are not doing their job right. On the other hand there are other needs in business than cutting costs. In the end cost cutting is a valuable tool but not a business model. You can’t run a company with as only mission statement "we’re cutting down on our costs”. So I think the private cloud might be more than just a transition model. It can live on, but probably not for most businesses. Depending on their needs I see a very bright future for hybrid cloud, both for transition and as a permanent solution. I would be hard pressed to call the choice for private or hybrid cloud wrong. It all depends if it’s a decision made for the right reasons. One should always note that choices and decisions have a limited life span. Business is very competitive and moves very fast and the very nature of cloud computing will only accelerate this.

I won’t surprise anyone that a lot of discussions around cloud are based on some assumptions. One of them is that we are discussing very well run organizations. Businesses and governments that have a clear understanding of their IT & business needs, have an IT strategy to support that and who use the best fitting management styles and methodologies as required and dictated by those needs. Sigh, perhaps it’s me but, while I so see occurrences of this at companies, I have never worked at or for one that is that well squared away. And, to me, becoming a financial sound success story with your business and IT in the cloud requires just this. Perhaps the lure or the push of the cloud will achieve for some companies and organization what nothing else has achieved, help transform them into better run entities. Some things, ugly hacks, internal IT can do (unwillingly) now are not possible in the cloud. The financial pressure will be bigger as well. It’s hard to hide or forget about certain costs in the cloud. If there is one thing, ISP, Telco’s (transforming into cloud vendors, but by origin giant “billing engines” for communications) and native cloud vendors are very good at it is sending you the monthly invoices. When things become visible they tend to attract attention. Sooner or later the bean counters will find you. A lot of the existing companies with legacy IT and politics will have a harder time dealing with all of this than the new, emerging ones that are built from the ground up using utility computing, so it’s time to step up to the plate and at least practice batting.
