5 Essential Tips for Maximizing Your Experience at Nutanix .NEXT for Bloggers
Super cool! Thanks Jon for the great info!
It would be cool to be able to assign protection config/sla details directly to a cluster or to a storage container - an additional way to view/interact with the infrastructure
I had a hunch that we'd see huge disk usage savings with cloning, but want to double check with the community. We basically, have a 125GB thin provisioned template. We've deployed 100+ VMs from this template (all deploys were also thin). we are seeing mind boggling savings in disk usage and I'm thinking its due to the way Nutanix handles the clones on the back-end. IE, it's just a creation of a new block map to the immutable block map, so almost no cost with regard to disk usage. I get that as the VMs overwrite and write new data the disk usage will grow, but we are seeing usage of 1.5GB or so per VM in stargate page. Again, this is sort of what I expected, but the very little bit of disk space used is crazy. Wondering if everyone else is seeing the same thing. I'm not thinking shadow clones play a part here as they are more active in mult-reader scenarios and also I'm thinking only improve performance and not actual disk usage.
This information is matching up Jon. I'm good. Get-NTNXContainer | select * usageStats : {[storage.user_unreserved_own_usage_bytes, 0], [storage.reserved_free_bytes, 14250607808512], [data_reduction.user_saved_bytes, 1406468054528],[storage_tier.das-sata.usage_bytes, 255844720640]...} storage.reserved_free_bytes, 14250607808512 = 12.96TB
thanks for the reply John and you beat me to my next question of how do you protect against exceeding the actual usable disk amount if you are thin provisioning with lazy :) Very cool on using metadata magic to improve things. So, if VMs are provisioned thick, I'm assuming dedup and compression will not allow for overcommiting storage as the space will still be reserved per the VM being thickl provisioned.
