Hi Alex, Meanwhile, I have communicated with Dell about PowerFlex. Maybe it is more suitable for providing good performance with CloudStack for databases than NFS. As you can see, I like CloudStack and want to use it more and more in our company. Best regards. Leo Replied Message

Volatile VM disks?

image. The VM root disk is not resetting on shutdown/reboot. I looked through the CloudStack source code but don't see anything obvious as to what would make the disks reset on shutdown/reboot. Is there something else I need to do to make this work? Is this a feature only on specific hypervisors? Thank-you, -Leo

Questions about Cloud Stack scale

machines? Anyone know of the largest installation? - What is the VM placement rate? i.e. How many VMs create requests can be submitted and how fast does the scheduler process these requests? - Any pros or limitations compared to other cloud softwares like OpenStack or Kubernetes others? Thanks, Leo
