10x hanccocka, <br />
is there any problems if my vmware servers in cluster are not with the equal amount of RAM.<br />
Also do you think there will be any problem mixing different type of memory(2,4,8,16GB) in one blade. Maybe something from your expierience.

<div class="content wysiwyg-content">
I have &nbsp;IBM blade servers HS22 with 12 DIMM slots. 10 of the slots are full with memory(with 2x2GB,4x4GB and 2x8 GB). I want to upgrade the RAM on the servers and I was wondering if I am able to use 2x16GB , because I have only two spare slots.<br />
OS on the server is VMWare 4.1U1.<br />
Do you think that I will have some problems?<br />
I will appriciate also any other options.

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.

Server Hardware

Components are those devices that are internal to a computer -- the PC boards, the central processor (CPU), the memory (RAM), disk and video controllers and so on.

Components

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.
