Free ESXi memory limitation

Hi folks,

Are there any plans to increase the 32GB memory limit on free ESXi hypervisor to 64GB?

Hey smadhura,

That hard limit on memory was only till 5.1. Now you can go upto 4TB RAM on free ESXi from version 5.5

These are the new maximums:

  • vSphere 5.5 supports 320 Physical CPUs per ESXi host
  • ESXi host supports 4 TB of Memory in vSphere 5.5
  • 16 NUMA Nodes per host in vSphere 5.5
  • 4096 Maximum vCPUs per host
  • Support for 40 GBps Physical Network adapters
  • 62 TB VMDK virtual disk support
  • Supports 16 GB FibreChannel end-to-end Support
  • Increased VMFS Heap, 64TB open VMDK per host max
  • Virtual Machine Hardware Version 10 in vSphere 5.5

Don't see how that help?  It appears to only cover 5.1, and not 5.5...

Hello, can you, please, tell me, what amount of VRAM can be allocated to one virtual machine by free Hypervisor? I've looked hard through vmware site, but found only "no more limitations to host RAM from 5.1". I'm interested exactly in vram per virtual pc. Thanks in advance!

The limit in 5.5 for a VM is 1TB (host has a 4TB limit).  http://www.vmware.com/pdf/vsphere5/r55/vsphere-55-configuration-maximums.pdf

Thanks a lot, but can you  please tell me, what limits for VMs in free version of vSphere (not in evaluation version of vSphere, but in vSphere Hypervisor, if i realized correctly)? Or those limits works for all versions of vSphere? By the way, is there any licence agreement or vSphere Hypervisor, where listed all usage limitations? On vmware site i found only vSphere specs. Or i looked badly? Thanks in advance again!

When you get the free license, you have to register how many physical machines it will run on, but not aware of any limit.  I think there might be a two physical CPU limit per physical box but don't actually see that specified, and I have not installed 5.5 yet...  (so someone will likely correct me if I am mistaken).

I did find this on a blog: TinkerTry IT @ home | Best parts of VMware’s ESXi 5.5 free hypervisor rely on vCenter, whi...

... all the good stuff is only gotten from the vSphere Web Client. This is a rude awaking for many who may not have tried ESXi before. Examples of this good stuff include VMs with greater than 2TB drives, mapping USB 3.0 ports to VMs, better GPU handling, and vSphere Flash Read Cache. These compelling features are locked to hardware version 10 VMs, which cannot be managed from the vSphere Client, and cannot be run on ESXi 5.1.

So the biggest limitations appear to be you can't tie into vcenter / web client and are thus restricted to using virtual hardware version 9 (and below) VMs and their limitations.  That said, it does sound like you can manage many settings of virtual hardware 10 VMs with Vmware Workstation 10.

So you either want to make your you keep with vm hardware 9 machines, or at least have a version of Vmware Workstation 10 to connection to ESXi 5.5 hosts.

Hi Smadhura,

Currently downloading the ESXi 5.5 and going to install very soon, my server is having 64GB RAM and will prove if the 32GB RAM limitation for free ESXi is removed or not. As per VMware posts there is no RAM limitation with ESXi 5.5 free

Regards,

Nikhil

  • vSphere 5.5 supports 320 Physical CPUs per ESXi host

This is good. But how to understand this:

Essentials Kit:  License entitlement 3 servers with up to 2 processors each.

So if I have ESXi host with 3 physical processors, how is it possible to upgrade to Essentials Kit if limitation is 2 processors?

That is because the Essentials kit is a specialized licensing aimed at customer looking to make a small investment in software to set up a virtual environment and the ESXi host are limited to two physical cpus

Hi! I'm considering to choice vmware for virtualization starting from Hypervisor version, so after "evaluating" this version can I buy a Standard or other licensed version without reinstalling so only changing license type and upgrading to latest version?

I apologize for doubts, Thanks a lot!
