Microsoft Operations Manager 2007 R2 Sizing

Microsoft has published guidance on how to size your OpsMgr 2007 R2 installations:

“The Operations Manager 2007 R2 Sizing Helper is an interactive document designed to assist you with planning & sizing deployments of Operations Manager 2007 R2. It helps you plan the correct amount of infrastructure needed for a new OpsMgr R2 deployment, removing the uncertainties in making IT hardware purchases and optimizes cost. A typical recommendation will include the recommended hardware specification for each server role, topology diagram and storage requirement. The Operations Manager Sizing Helper is most useful when used with the Operations Manager 2007 R2 Design Guide”.

Microsoft Active Directory Design Guide

Microsoft has published an Active Directory design guide

“This guidance provides general recommendations for the design, deployment and management of an Active Directory environment in a healthcare organization according to current best practices. The purpose of this guidance is to accelerate Active Directory design and deployment in a healthcare organization, and provide a framework for a more consistent network operating environment”.

VMM 2008 R2: Host Needs Attention After KB978560

I saw this one last night for myself and I’ve just seen a week-old post by Mike Briggs on the subject.  When you deploy KB978560 to your VMM 2008 R2 server, it will require an update to the agents.  You’ll see a yellow exclamation mark icon appear on your hosts.  When you check their status you’ll see that you must take manual action to resolve the issue.  Simply right-click on the managed hosts, update the agent, and provide any required credentials.  It takes a minute or two, then you’ll get your “issue” resolved. 

Be sure to put the hosts in maintenance mode in OpsMgr if you’re using it.  Otherwise you’ll get a bunch of alerts for every host you upgrade.

Some HP and Hyper-V Links

Patrick Lownds, a fellow virtualisation MVP over in the UK, has provided a couple of useful links if you are running Hyper-V on HP equipment.  The first is a post on best practice guidance if you are running Hyper-V on a HP EVA SAN.  There is a whitepaper that goes through HP’s recommendations on this.  It was interesting to see they saw a fixed VHD’s get 7% more IOPS at 7% less latency than dynamic VHD’s.

The ProTips for HP are also available.  They’re not easy to find but Patrick provided me with a link.  The idea here is that HP SIM agents (which you should be installing, even if you don’t use the HP or other management software) detect hardware issues.  OpsMgr then picks up the alert and notifies VMM using the HP Pro Tips.  VMM can then take action, e.g. migrating VM’s from one host to another in the cluster.

European Union Windows Browser Choice

KB976002 describes what operating systems will receive a choice of Internet browser and how this process will work.  This will bring Microsoft into compliance with the much discussed demands of the European Union on this subject.  Affected OS’s are:

  • Windows XP Service Pack 2 and Windows XP Service Pack 3
  • All editions of Windows Vista
  • All editions of Windows 7
  • Future versions of the Windows client operating system that are released within the duration of the agreement with the European Commission

Some more information on the process can be found on Stealth Puppy.  I’ve not seen the update yet but it appears to be delivered by Windows Update.  If you don’t have Windows Update enabled then I guess you don’t get a choice.

If you are running tightly controlled corporate PC’s then you’ll be glad to hear that you can prevent the update from being deployed via WSUS/ConfigMgr/etc.  You can also use the registry, according to KB2019411 (and therefore group policy) to prevent the update from executing:

  • Key: HKLMSoftwareBrowserChoice
  • Value: Enable (REG_DWORD)
  • Possible settings: Enabled = 1, Disabled = 0

OpsMgr Empirical Performance Data For Server Sizing

We have a customer who has a number of physical machines hosted with us.  They were deployed before we had a virtualised environment.  The specs were defined by the customer based on what they thought they’d need for a new service.

They asked us to look at replacing (not converting) their Windows Server 2003 web servers with Windows Server 2008/2008 R2 virtual web servers.  They also asked if the back end servers could be looked at as virtualisation candidates. Operations Manager to the rescue!

OpsMgr is constantly gathering performance data.  It keeps over a year of it in a reporting database.  I ran some reports.  CPU and memory were the two important ones.

The web servers were simple enough.  Their CPU average utilisation proved to be low with the occasional spike.  The standard deviation was very small and the spikes were very infrequent.  As Hyper-V VM’s on a cluster, this is no problem.  If a spike is detected by OpsMgr, the VMM Pro Tips integration will move the VM using zero-downtime Live Migration to an idle host and allow the VM the CPU resources it needs.  As it turns out, they use exactly 50% of their RAM.  The nice thing here is that we have empirical data to justify a reduction of the ram by 25%.  If it needs to go up then it’s just a couple of minutes of mouse clicks to do that.

The back end servers were another story.  The average CPU was low, but not quite as low.  I also could see much more frequent CPU spikes.  The standard deviation was much greater.  To be honest, this was what the customer and I both expected.  These machines are not virtualisation candidates.

So instead of doing a blind P2V, or sticking a wet finger in the wind, we went through a scientific decision making process, courtesy of the reporting database in Operations Manager 2007 R2.  There will be no worrying about any future deployment, we should know what the end result will be.

Why Should You Go To Minasi Conference 2010?

Everyone knows that budgets are slashed and the opportunity to attend big and expensive conferences so you can stay up to date is probably gone.  Well there is a more economic way to stay up to date.

Mark Minasi (well known TechEd/WinConnections speaker, Windows IT Pro journalist, Mastering Windows Server 2008 R2 author) will once again be hosting a conference in his home town of Virginia Beach, VA, USA.  It’s a low cost, non-profit event that is aimed squarely at the IT Pro.  The registration cost is a measly $450 which is around €330.  It’s 3 days full of techie talk, including Windows Server/Desktop, virtualisation, SBS/EBS, Exchange, SharePoint, PowerShell, Active Directory, security/certificate services, SQL, and a whole lot of fun.

This is not WinConnections or TechEd.  It’s a whole lot smaller and all of the speakers are techies.  Because this event is smaller, everyone is approachable and they’ll try to answer any question.  Every session is very interactive, and most of the speakers can usually be found afterwards in the bar, at breakfast/lunch, or at the party.

It’s not only sessions or classes here.  Intercontinental friendships, both personal and professional, are formed here every year.  Delegates look forward to meeting up with friends again, and with figuring out problems with other delegates.  The opportunity to network is unmatched … everyone is made welcome, we pretty much all have breakfast and lunch together.  And whether you want to party or just hang out for a quiet evening, you’ll have some company.

The speakers include authors, journalists, consultants, administrators, MVP’s, and people respected on the Internet for the experience and willingness to help.  Something quite original was tried last year and it’s being repeated this year.  Mark likes to encourage people to develop their skills, be it technical or otherwise.  Many of the speakers at the conference really only started doing this stuff here.  Most people would run at the thought of speaking for 75 minutes.  So last year we tried running mini-sessions where attendees could talk for 15 minutes about stuff they had done that might be interesting, e.g. a first time delegate spoke about how to build a PC at home for running VMware ESXi.  It was a success and it’s being repeated this year.

We also push outside the usual topics to boost personal development.  A few years ago Mark did a session on how to do technical presentations.  It was a hit and provided great information, some of which I try to use.  This year Eric Rux (an editor with Windows IT Pro) is talking about how to get into writing.  With Mark Minasi, and a bunch of other writers (book and magazine) in the audience also taking part, there’ll be a lot of information. 

Previous attendees will know that each conference is pretty much formed the year before based on feedback.  It really is a conference that is “owned” by the delegates.  A perfect example is PKI/certificate services.  Last year it seemed to be mentioned in half of the sessions and most delegates had no knowledge or experience in dealing with this technology.  A Q&A session on content pretty much steered the speaker recruiting.  So this year we have Roger Grimes (MS security architect) in to talk about it.  Take a peek at the below schedule and you’ll see how much interaction there is: panel sessions, Q&A sessions, etc.  Check it out and see if you’ve got a time slot in May to attend.  Here’s the schedule for 2010:
