image.png

This is just a quick post to confirm that VMware vSphere/ESXi 6 runs on the HP Proliant ML110 G6.  Although this is now an older server, it is still very much capable and I know that there are still quite a few being used in home/work labs, hence this post. The CPU, Memory, Storage Controller and Network Adapter are all detected out of the box.  I used the HP image of vSphere ESXi 6.0 that I downloaded from here. The images below show what is presented through the vSphere Client – I … [Read more...]

Running VMware vSphere 6.0 on HP Proliant MicroServer G7 (N54L)

VMware vSphere 6.0 on HP Proliant MicroServer N54L

I’ve had a few folks contact me over the past couple of weeks asking if VMware vSphere 6.0 will run on the HP Proliant MicroServer G7 (N54L)?  Well, the answer is yes, most definitely.  The standard VMware vSphere 6.0 ESXi detects the CPU, memory, disk and network correctly, without the requirement for any hacks or tweaks to the ESXi image.  The HP vSphere 6.0 image wasn’t even required for installation. In my lab I am running ESXi 6.0 directly from a USB pen drive that I have inserted into … [Read more...]

Up until vSphere 6, it has only been possible to provide real-time fault tolerance for single vCPU VMs.  What this meant for those VMs with … [Read more...]
