UCS C200 M2 with raid 5

[MRPFNZCCO]

I'm trying to figure out if I can run raid 5 with four new ssd drives I have connected.  The LSI Raid utility only shows raid 0,1 and 10 but raid 5 is greyed out.  How do I get raid 5 option available. If raid 10 is supported why wouldn't raid 5 be?

Which Raid-Controller do you have

It's using the LSI controller but I'm trying to figure out if it's using the Mezzanine controller or the PCIe.  On boot up it's showing (see attachment)

How to Determine Which Controller Is in Your Server

If no models of card are displayed but there is a RAID configuration, your server is using the
onboard ICH10R controller. You are also prompted to press Ctrl-M to launch the configuration utilities for this controller.

According to this, you are using the integrated controller ! and this is the reason, that raid-5 is not supported !

That's what I was afraid of. Control M brings up the LSI utility which shows Raid 0, 1 and 10 options.
