Hewlett-Packard has just released a Generation 8 Microserver which is going to replace the well known N36L/N40L/N54L Microservers. The new server has the same trendy design as the entire Gen8 series. The AMD Turion CPU has been replaced by an Intel Ivy Bride CPU which is way more powerful and the memory limit has been raised to 16GB. With that, the new server brings much more power to your VMware vSphere Homelab and allows you to run more virtual machines. In this post i am going to compare both specs to point out what's new and better.
Be careful when updating you ESXi hosts from VMware vSphere 5.0 to 5.1. The following servers were supported in 5.0 but are no longer supported in 5.1:
When you want to add many VMware ESXi Hypervisors to your vCenter inventory, a small one-liner might save you a lot of time. You can add hosts based on consistent host numbering, IP-Addresses or use a textfile for input.
With vSphere 5.1 the command line interface esxcli has introduced many new features. The esxcli is a complete set of commands that you can use to automate you environment or to perform advanced tasks like lun masking. I have created and printed a mindmap to navigate through the namespaces more quickly
ESXCLI has 10 namespaces whose names are self-explaining:Read More »ESXi 5.1 - ESXCLI Command Mindmap

If you change your hardware configuration without reinstalling your hypervisor you might run into an issue with the nic or hba port numbering. The ESXi host writes the PCI bus to vmnic mapping to a special configuration file. If you change the pci slot from your dual port nic for example you end up with 2 new vmnics.
The configuration file is located at /etc/vmware/esx.conf
