The general rule told is always under 80% utilization on a Datastore. However, if I capped my utilization from the SAN itself, is there any reason to still stay under 80% utilization of a Datastore ?
Let's assume I am NOT using Thin Provisioning.
Example:
Let's say I have a 10TB Array on my SAN, and I then decide to only use 80% - 8TB. I then create 8x1TB Datastores and present them to my Hosts.
Again, using Thick Provisioning only (Or maybe with some cautious thin provisioning), is there any reason why I can't essentially fill up the Datastores ? I know there needs to be space for logs, snapshots if I plan to use them etc etc...but with all that in mind, is 80% still a relevant concern ?
Thanks
If snapshots and log files are something you are aware of, and you aren't doing thin provisioning of the VMs themselves, theres no reason to stop at 80%.
Thanks for the confirmation.
This is helpful for some planning I'm doing.
