Once the Virtual Machine Properties setting is shown, you can click on Memory which will show you a nice slider.

VMware ESXi Add Memory to VM – Edit Settings You can also do this from the menus in the VMware vSphere client. Once you know the virtual machine, right click it and select edit settings. VMware ESXi Add Memory to VM – Go to virtual machines In this case, I am using an OpenIndiana 151a virtual machine which is providing ZFS storage functions. The first thing you want to do is go to the virtual machine you are attempting to allocate memory to. One other note is that you want to shut down the virtual machine you are editing before starting the below instructions. If you cannot get this far, it is likely you should be thinking about a simplified setup. I am also assuming you are logged into the ESXi machine using the VMware vSphere client. You will have great difficulty trying to give your ZFS storage VM 24GB of RAM and a Linux VM 8GB of RAM if you only have 16GB of physical memory installed, even if you try overprovisioning.

Power Supply: Corsair AX650 650w 80 Plus Goldīefore we get started, a huge assumption here is that you do, in fact, have additional physical memory available.

Memory: 8x 4GB Kingston unbuffered ECC 1333MHz DIMMs.

If you want to read about the inexpensive, yet very powerful build, you can learn about the AMD Opteron 6128 ESXi server here. Test ConfigurationĪgain it is time to fire up my ESXi 5.0 test bed. This simple guide goes through how to change an ESXi VM’s memory allocation in the most basic form since a lot of users can be intimidated by the concept of being able to change RAM allocations to the different machines.

With ESXi 5.0 having a 32GB limit in the “free” edition, partitioning memory to the various virtual machines becomes an important task. With that being said, OpenIndiana (a commone OpenSolaris derivative) does like to use as much RAM as possible for caching. Generally an OpenSolaris derived OS is used for storage as it provides both ZFS as well as native iSCSI to provide other virtual machines, and other network devices with fast, reliable and redundant storage. One very important aspect to the ESXi 5 All-in-One systems that have become very popular is getting the memory mix correct.
