VMware has published a new whitepaper called VMware vCenter Server Performance and Best Practices. This is a must read if you manage a vCenter 4.1 installation, or are currently planning your upgrade. The whitepaper highlights the performance improvements in the latest version, sizing guidelines, best practices and some really good real world information from several case studies. One simple, but probably often overlooked tip, is that the amount of vCenter Clients connected to your vCenter Server has an impact on it’s performance.

Over at PlanetVM Wil van Antwerpen posted The Future of VMware Server back in May 2010. Wil makes the argument that it seems like VMware is indeed abandoning VMware Server as a product, leaving us with VMware Workstation and VMware Player as the two Windows installable virtualization solutions from the company.

As you may or may not know, the new vCenter 4.1 requires that the host it runs on is 64 bit.

Welcome to vNinja!

Welcome to my new playground. I used to post quite a lot over at my old site, h0bbel.p0ggel.org but given it’s weird domain name and it’s long history I’ve decided to start fresh. This new site will be dedicated to all things virtualization, PowerShell, Windows Server management and possibly even some Citrix products thrown in here and there.
