Hi welcome to the communities,
I've moved your thread to the 3.5 forums.
According to the configuration maximums esxi 3.5 u2 is capable of using 256GB RAM.
The free hypervisor licenses support much less though. But U can't even remember if there was a free license in 3.5. Maybe time for an upgrade?
Thanks for your reply. As you have mentioned that the free hypervisor licenses support much less RAM, Is it possible to check how much RAM is supported in free ESXi 3.5 u2 version?
Thanks in advance.
Well, todays hypervisor license supports less RAM. Not sure if 3.5 U2 was limited as well. I can't find any infos about it.
I upgraded the Physical RAM from 16GB to 32GB on ESXi 3.5 host and the performance of the Virtual machines running CentOS 4.6 guest OS really went down. What could have resulted in slow performance as a result of upgraded RAM as in my opinion it should have been much better? I haven't changed any configuration towards Guest OS/VMs. Please suggest.
Thanks & Regards
