i have a 2 exsi servers, i got few questions and i ran in to few problems
1.) if the server has 8 gb ram , is it ok to create vm machines more than 8gb(example 6 X 2GB ram machines) or will this have performance issues ?
2.) how do i find out if i am overloading the EXSI, is there a place in vsphere client to check this ?
3.)in one of my exsi mechines it gives all sort of problems with vm mechines if i create mechines more than 8 gb ram but in the other one it works gr8. what could be the problem. is there really a way to check how much more can i add ?
You can check memory overcommitment via SSH.
esxtop command, then press m and you should see at the bottom line something like this:
1:28:19pm up 2 days 18:47, 518 worlds, 42 VMs, 42 vCPUs; MEM overcommit avg: 0.00, 0.00, 0.00
look at the avg: if they are more than zero, then you overcommiting RAM.
