I recently purchased a HP N40L Microserver for my home vSphere lab, with the intention of buying a second unit to create a small vSphere cluster for lab work. This would take me away from having nested virtual ESXi hosts. You can actually currently get great deals on this hardware – with HP offering £100 cashback on the purchase cost. I ended up paying around £260.00 for my HP Microserver, getting 100 off, which means it only cost about £160.
For this price, this microserver makes great hardware for a home lab cluster build, however the one thing that has always been a downer on this is the fact that all specsheets and official documentation from HP list the maximum amount of RAM supported as 8GB for the Microserver. This doesn’t leave much room for VMs to run per host.
Today I received an interesting e-mail in my inbox from Serversplus.com. They claim to have tested running 16GB of Crucial ECC DDR3 Unbuffered (2 x 8GB modules) in the HP N40L Microserver! This, if it is true (which I am sure it is, as they are now selling bundles with 16GB RAM), is great news for us looking to build home labs on the cheap. Sure, 8GB modules are much more expensive than 4GB at the moment, but we now know that there is no 8GB limit on the N40L Microserver – rather 16GB. As soon as I can afford the two 8GB modules for a total of 16GB, I’ll be looking at upgrading my current Microserver to 16GB. If this works, I’ll definitely be purchasing a second unit.
Here is a screencap of the e-mail I got from serversplus.com –
