Howt to calculate the maximum memory that can be used in Hyper-V

-

most of time start using "rule of thumb" of 3/4:

all vms must not use more 3/4 of total physical ram of host/physical machine

i´t s "good guess"?

of course dependes on many factors, backup software or other components besides hyper-v, dynamic memory , on.

so, found on biztalk tech article following rule:

300 mb the hypervisor

  plus

32 mb the first gb of ram allocated to each virtual machine

  plus

another 8 mb every additional gb of ram allocated to each virtual machine

  plus

512 mb the host operating system running on the root partition

it right?

this rule ok? it´s measure?

hi,

for windows server 2008 , server 2008 r2 host os formular right. later operating systems don't have worry since operating systems automatically reserves needed ram.

regards,

benedict
