is there any documentation how much disk i/o the scratch/swap disk can get to?
i need to decide whetever installing the esxi on the same big raid 10 aray together with data , or to build aditional 2 disks raid 1 aray dedictaed for esxi OS and scratch for performance gain.
this topic is very confusing and althought vmware recomends installing the OS on dedicated disks i can't figure out the reason and any documentation about it.
i know that the esxi OS get completely loaded into RAM it's just the scratch space i didn't sure about...
