Re: How much of datastore should be left for the host its own to run

Thanks for your prompt answer.

I just want to make it clear on my understanding. Can you please help to correct if I am wrong. Surely that when I get everything clear, I will mark the question as answered.

Example: I have a ESXi host have datastore 3.08 TB = 3153 GB. There is no VM machine created yet. Now, I want to create a new VM machine on that host with total hard disk about 2024 GB and RAM = 32 GB

According to the formula I would have: (2024 + 32*1.1)*1.1 + 12 = 2277 GB.

So the question is that with the amount of datastore left of 3153 - 2277 = 876 GB, is 876 GB enough for my ESXi to run its own code and structure?

My understanding from the case: VMFS Datastore Free Space Calculations | Simon Greaveshttp://www.simongreaves.co.uk/vmfs-datastore-free-space/ to give you how to calculate the physical disk space in total before you can start creating VM machines. It seemed to be a bit different from my question above.

Please advise.

Thank you
