Placing the datastore clusters inside a folder in some cases is not an option, so i decided to write a PowerCLI script which creates the permisson after vCenter service restart. As you might know, all permissons set at datastore cluster level are gone after vCenter restarts. This workaround referred to VMware KB: 2008326.
First you have to find affected permissons. This applies to permissons which are set directly to datastore clusters. A datastore cluster is referred as "StoragePod", so this is the keyword:

As you can not control the VSA Appliance, questions come up how to properly shutdown the VSA Cluster. So here is the answer: Shut down… Read More »Shutting down the VSA
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:
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.
