Installing HP P420 smartraid controller on Workstation Z420

HP Recommended
HP Workstations Z420
Microsoft Windows Server 2016

Hello everybody

I have a Z420 with Xeon E5-1620 with 32GB RAM and a 500GB Samsung 850, running Windows Server 2016. (I use this machine as a small office Server)

Just bought an HP Smart Array P420 Controller with 1GB FBWC to use it, instead of using the integrated controller.

Installed the board on the machine Ok -

Switched on the machine - Finds that the controller in Slot5 Ok

Attempts to discover hard drives connected - FInds none (which is the case as I have not connected any)

Then says Press F8 to configure array or ESC to continue.

Now the problems start !!!

Pressing F8 ofcourse finds no drives (I guess SSD is not shown as it is connected to motherboard)

Pressing ESC does nothing and the computer does not boot at all

Took out the RAID controller - all normal as before.

My question is

a) Is the P420 compatible with Z420 workstation ??

If YES then

Can I use the current SSD connected to motherboard as boot drive and create an array of drives connected to the P420 RAID controller for DATA storage  ??  or all drives should be connected to the RAID controller 


Your help will be greatly appreciated to achieve the above configuration (orelse I guess I will have to put the contoller on my drawer !!)

Hi again

Forgot to mention that when the RAID is installed in the machine it is not possible to enter the machine BIOS Setup (by pressing F10)

Also please note that my computer runs on the latest BIOS
