Running VMware vSphere 6 on an HP Proliant ML110 G6


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...]

Mounting 2.5” SSDs into an HP MicroServer

Mounting 2.5” SSDs into an HP MicroServer

Hey folks, just a quick post to show you my preferred method of mounting 2.5” SSD’s into my HP Micro Server, which I use for my VMware lab server. Most entry level servers, such as the MicroServer, as still equipped to primarily deal with 3.5” form-factor drives which in almost all instances excludes traditional SSD drives. It is technically possible to push a 2.5” SSD straight into the SATA port of the MicroServer, after removing an empty hard drive carrier.  The light weight of an SSD … [Read more...]

Looking within the Windows Explorer window I confirmed that the OS could see the device and that it was accessible (see below). I had the … [Read more...]

In my lab I am running ESXi 6.0 directly from a USB pen drive that I have inserted into … [Read more...]
