VMGuru.nl – I choose (a virtual) life!

Last night VMware has released Update 1 for ESXi 4, ESX 4, and vCenter server 4.

According to the release notes Update 1 includes the following improvements:

• Support for Windows 7 and Windows Server 2008 R2;
• Support for View 4;
• Support for 160 VMs per host in a HA cluster with 8 hosts or less;
• Increased vCPUs per core limit from 20 to 25;
• Paravirtualized SCSI support has been extended to Windows 2003 and 2008 boot drives;
• vDS performance improvements;
• Support for DB2 database;
• Improved support for Microsoft Clustering.

Besides this vCenter server now includes a pre-upgrade checker tool which enables you to proactively check ESX hosts for any potential issues that you might encounter while upgrading vCenter agents on these hosts as part of the vCenter Server upgrade process. You can run this tool independently prior to upgrading an existing vCenter Server instance. The tool can help identify any configuration, networking, disk space or other ESX host-related issues that could prevent ESX hosts from being managed by vCenter Server after a successful vCenter Server upgrade.

The release note can be found here.

vSphere 4 Update 1 can be downloaded here.

I’m in IT for more then 12 years and during that period I learned, never to trust something another professional tells you. So as I am studying for my VCP410 exam, coming Friday, I came across the Virtual Machine configuration maximums. I saw the info at Simon Long’s blog, took his VCP vSphere 4 Practice Exam and also took notes.

When running through all configuration maximums I remembered the ‘never trust anyone‘ motto and as I’m in between project I thought it would be cool to check/confirm the presented maximums. Some seem so ridiculous that you can hardly believe them to be true.

After 10 minutes of editing the virtual machine configuration I got my ‘MAXVM‘ and I must say VMware delivers one awesome virtual machine. I can’t imagine anyone using a virtual machine which approaches these configuration maximums.

To sum it up:
