vSphere Client performs slowly on a Windows 7 system

August 5, 2011 / / 0 Comments

You can run into the following problems when running VMware vSphere client 4.x on a Windows 7:

  • Redraws are visibly noticeable, especially when maximizing the VMware vSphere Client 4.x
  • The performance of the vSphere Client is slow

Well the problem is the desktop composition, short aero from Windows 7

Desktop composition is also known as Aero. It can either be disabled globally or on a program by program basis. Having it disabled while running such things as 3D games may provide a performance bump.

You can resolve the problem by disabling the aero, if you like the aero you can just disable it when running the VMware client. This can be done by following the next steps:

  1. Right-click the shortcut for the VMware vSphere Client and click Properties.
  2. Click the Compatibility tab.
  3. Select the “Disable desktop composition” option
  4. Click Ok

When you open the VMware vSphere client now you will see that the aero will be disabled and the vSphere client will preform normally.

Desktop composition is also known as Aero. It can either be disabled globally or on a program by program basis. Having it disabled while running such things as 3D games may provide a performance bump.

NetApp – Data ONTAP Simulator 7

July 15, 2011 / / 0 Comments

Since last year I’m doing some more work on our NetApp infrastructure.
Since I don’t have any training in storage management and certainly not in NetApp devices, I was always afraid to do something because I couldn’t test it. I have some basic knowledge  and some experience in home storage solutions like Freenas and Openfiler that helped me allot to get the basics in Netapp.

Surfing the NetApp site I found out that they have a simulator … mmmm intresting

Do you want to build or test a solution but don’t have access to NetApp storage? The Data ONTAP simulator, a tool that gives you the experience of administering and using a NetApp storage system with all the features of Data ONTAP at your disposal, is the answer. Download the simulator; discuss usage; and share your experience, technical articles, and best practices here.

This seems perfect for me to get some more experience in the NetApp environment and trying out solutions before I implement them.

So I went on and tried it out. Here is how to set it up:

First of all download the ISO from the Netapp website

(I downloaded version 7.3.5 because that is the current version in production)

The link to the simulator download page (login required):

Since I have a vmware test environement I will install the simulator on a virtual machine. Continue reading

vCenter disconnect Idle connections

July 13, 2011 / / 0 Comments

In the previous post I introduced you guys to basic PowerCli

Well Today I’ve got a practical example script.
Over the last few weeks we had a lot of open sessions on our vCenter server.
This from people leaving there client open and never closing them (retards, sorry for the language).
This generated some idle sessions from a few hours to a few days :-S

This got so on my nerves that I wanted a solution for this, unfortunately vmWare did not implement the feature to disconnect idle session after a specific time in the Client or vCenter settings.

So time to build a script Continue reading

Powercli small introduction

July 12, 2011 / / 0 Comments

Ever needed to do some bulk operation in you’re vmware virtual environment ?
Or just needed information of a bunch of virtual machines ?

Then you probably had a lot of manual labor to do in the vShere client.
Well vmware came with  a solution:

The program is called VMware vSphere PowerCLI and more information can be found here.

A short discription in the words of vmWare:

VMware vSphere PowerCLI provides a Windows PowerShell interface to the vSphere API. vSphere PowerCLI includes PowerShell Cmdlets (pronounced, “command-lets”) for administering vSphere components. In addition, the vSphere PowerCLI package includes the vSphere SDK for .NET for developers who want to create their own applications.

Let’s get started implementing and using the PowerCli
