Hello All,
Let me start off by saying this is a great forum and everyone here has had some great feedback.
I have a new environment that I am using to migrate our VM's off of older ESX servers.
The VM's that were created originally have been given very large disk sizes (100G) and are only using between 15-40Gb of space.
Some people here have had a bad experience with thin in the past because they ran out of space and the system crashed, but I don't think anyone was really keeping an eye on any systems space.
I have decided to use Thin on some of the VM's that I am V to V'ing over from the old ESX servers to help reduce space used.
Here are my questions
1. If I thick provision some VM's and Thin provision others, even if for some reason we run out of space will the thick provisioned VM's be effected??
2. If I enable SDRS and create a cluster of datastores will VM's automatically storage vmotion to a datastore with available space in the event a datastore starts to fill up??
3. Can I use Storage Vmotion to change from THICK to THIN if needed??
What is the general consensus with Thin provisioning?? how many people here use Thin vs Thick??
Currently we have a 2 node DL360 cluster using HPE VSA to create a virtual SAN using the internal Drives in the DL360's.
