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

Without a shared storage it is quite hard to deploy a reasonable test scenario. Within vSphere 5 VMware introduced the vSphere Storage Appliance (VSA). The VSA transforms the local storage from up to 3 servers into a mirrored shared storage. This sounds really great for a testing environment because it supports plenty VMware Features like vMotion, HA and DRS.
Prior to installation there are a few things to check because the VSA has very strict system requirements. As it is only a testing environment and I do not consider getting support, so the main goal is getting the VSA up and running. The server requirements are:
- 6GB RAM
- 2GHz CPU
- 4 NICs
- Identical configuration across all nodes
- Clean ESXi 5.0 Installation
I deliberately ignored all the vendor/model or hardware raid controller requirements, as this are only soft-requirements. The HP Proliant N40L supports all above requirements, except the 2GHz CPU. But there is a little XML File which contains the host audit configuration the installer uses during the installation. I am going to tweak this file a little bit to get the installation done.
