Problems installing Windows Server 2016 Datacenter Edition on raid

Hello everyone, this is my first post and I count on your support.

I am currently trying to install Windows Server 2016 Datacenter Edition using Windows Deployment Services on two discs 136.12gb raid 1, but this will not let me because it says I need at least 150GB HDD to proceed with the installation, the same method is applied in virtualized machines in hyperv and Proxmox and does not throw me any error. (see attached image)

The server details are as follows:

DELL poweredge r610
128gb ram
intel xeon 2.67ghz 6 core

4 hdd en raid 0 each independent:
hdd 931gb
hdd 931gb
ssd 446.42 gb
hdd 1862.50 gb

2 hdd both raid 1:
hdd 136.12 gb
hdd 136.12 gb

I count on your support.

Thankful in advance.

Best regards.
