The return of Mr. McCaw

It realy is great to hear that Rory McCaw is going to present 2 sessions at the Tech Days on the 12th and 13th of March.
Of course he will be speaking about Operations Manager 2007 related topics:

March 12 (10.45 - 12.00)
Providing Remote Management Services with MS System Center Remote Operations Manager 2007

March 13 (16.15 - 17.30)

See you all in Ghent !

Vista SP1 will be distributed via Microsoft Update Catalog, but having issues in SCE

Windows Vista SP1 will be released as an update on Microsoft Update (MU) Catalog. The patch is very large and there is a bug in Windows Server 2003 in the WinVerifyTrust API that will cause signing validation to fail.

What this means is that once you approve this update on a System Center Essentials 2007 server on a Windows Server 2003 server, every time the server sync’s from MU it will redownload the package, fail the cert validation, and so the download will fail. The problem will continue until you install the WinVerifyTrust patch on the System Center Essentials server. This patch is a hotfix (not a public GDR), so is not intended to be widely distributed. We recommend it only be installed on the System Center Essentials server itself.

You can obtain this hotfix here:

Windows Server Update Services cannot download large Windows update files in Windows Server 2003

How tho make an override for the SWAP Disks

How to make an override for the monitor "Logical Disk Free Space" for all the SWAP Disks?

Out of the box the swap disks aren't discovered. Opsmgr knows the amount of cylinders, sectors, scsi ID and a lot of other stuff but doesn't know if there is separate disk that I use as a swap disk.

 On all my servers I have a separate logical disk that I use as a SWAP disk. The size of this disk never change so I don't want to receive the alert about "not enough disk space". My C drive contains also the pagefile.sys but for the C drive I definitely whant to know if there is enough disk space. 

So, here we have a challenge Smile

System Center Dataprotector Management Pack

Microsoft released this week the DPM management pack for OpsMgr. 


Feature Bullet Summary:

  • Centrally monitor the health and state of data protection for multiple DPM servers and protected computers.
  • In State Views, view consolidated state for protection activities in DPM at a glance. For DPM servers, view the state of database and service health, performance, and other indicators. For protected computers, view the state of connectivity, data protection and recovery operations.
  • Monitor resource usage and performance trends on DPM servers.
  • Monitor actionable DPM alerts relating to protection and recovery.
  • Through MOM alerts, monitor the status of memory, CPU, and disk resources on DPM servers, and find out about database and service failures.
  • Read Product Knowledge to get comprehensive practical information for diagnosing and resolving alerts.
  • Use tasks to diagnose and resolve problems on remote DPM servers. 
Reminder: Have a look here for a guide on how to use DPM to backup OpsMgr and how to use Opsmgr to monitor DPM.

Congrats for SCUG.NL

Congratulations for SCUG.NL!!


Their first SCUG.NL meeting was great! Well organized, good presentations etc!

It was almost a 3 hour drive to zoetermeer from Belgium but is was worth it. 

You can download the presentations on there website.


First SCUG.NL meeting

 Our Dutch friends from SCUG.NL have their first meeting!!

The're going to give two level 300 presentations.

One about distributed applications and the other about management packs.

Check out  and register!!



Edit: Just got the confirmation that I'm registered! See you there! 

Capacity models:

Capacity models defines the performance characteristics of a specific application and its components and is stored within Capacity Planner. Capacity Planner uses these performance characteristics to simulate the performance of a deployed system.

At the moment only exchange 2007 is supported. Later on there will be also Microsoft System Center Operations Manager 2007, Microsoft Office SharePoint Server 2007, and Microsoft Windows SharePoint Services 3.0 models.

The models are based on System Architectural Models (*.SAM) .  System architecture model consists of the following information:

  • Topology: Site locations, types of networks, network components, and network characteristics (bandwidth, latency)
  • Hardware: Server distribution and characteristics, server and network mapping
  • Software: Server role and service mapping, file and storage device mapping
  • Usage profiles: Site usage and client usage

Application Model Technology Review

Application models stored in Capacity Planner consist of the following:

  • A list of transactions.   A transaction is a single instance of activity or work, as perceived by a user of Exchange Server.
  • A list of application components.   Application components are discrete parts of an application. For example, the mailbox store is an Exchange Server application component.
  • A list of workload parameters.   Workload parameters are values that are used by a capacity model as part of an action (for example, how large an e-mail message to send through a network interface), part of a transaction (for example, how frequently this transaction occurs relative to other transactions), or part of the overall simulation (for example, how many transactions to send). You provide the values for workload parameters in the Model Wizard and the Model Editor.

Hardware Limitations in Capacity Planner Application Models

The hardware modeling limitations for Capacity Planner application models are described in the following table.

  • Memory Capacity Planner does not actively model memory requirements. Memory requirement recommendations in Capacity Planner are based on best-practice advice for each application model.
  • Disks Capacity Planner requires single-disk configurations to have write caching disabled. If write caching is enabled on single disks in a test environment, simulation results that are obtained from Capacity Planner do not correspond to the actual test results.
  • CPUs As many as eight processors per server and two cores (dual core) per processor can be modeled.
  • Switches and routers Performance is not modeled, although visual indicators for these items are included in the capacity model, appearing in the Model Editor.
  • Firewalls  are not modeled. Capacity Planner models only required infrastructure that affects performance.
    Client computers Overall performance of client computers is not modeled, although network traffic to and from clients is modeled.
  • LANs Only packet-switched Ethernet networks are modeled. All network connections are full duplex.
