vmware hardware

I have vmware 4.1 servers.
I want to add 2x16GB  additional RAM on  servers but I am not sure if the version of vmware which I am using will support this.
Anyone who have tested this configuration?
Upgrade to new esxi version  is not an option so please do not propose me this.

you can allocate maximum 256 gb ram on the host.. so there is no issue on the upgrading in ram

MAX RAM per ESXi HOST is 1TB

see the maximums document here

We have many 4.1 Hosts with large memory capacities.

It will very much depend on your vSphere License, how much you can use!

Hi all, sorry for late response.
It seems that you didn't understand my question, I was not asking about max RAM per host, but for 2x16GB RAM DIMM which will be added to servers. My servers is a mixture with 2,4,8 GB RAM DIMM installed, and I want to put also 2x16GB on servers additionaly on IBM HS22 blade servers. Because this are little old servers I need to update the firmware, and I was wondering if the VMWare which is also old version(4.1) will recognize 16GB RAM DIMM.

It's not VMware which has to recognize a 16GB RAM DIMM.

It's whether a 16GB RAM DIMM is compatible with the Server Hardware!

According to this Web Page at a Glance

https://www-03.ibm.com/systems/xbc/cog/bc_hs22_7870/bc_hs22_7870mem.html

16GB DIMM is supported by a HS22 (7870) server.

If it's supported by the server, it will be supported by VMware vSphere 4.1.
