I am trying to install Debian on a SuperMicro server on two ssd's

Debian Stable does not recognize the disks at all.
Debian Testing's installation disk picks it up as a RAID1 device (even
when I configure it in the bios as non-raid disks) and can install up
to the stage where grub has to be installed. Grub does not recognise
the RAID1 device but sees the two disks separately.
When I open gparted in Linuxmint 17 (live imaget) it complains when
the disks are configured in bios as RAID1 but gparted sees the
separate disks when it is configured as non-raid devices.
I am prepared to go the route of a software raid if necessary, but in
the Debian installer that is only possible if the Debian-installer
sees the disks as separate disks as Grub does.
Any suggestions for the way forward? Should I put a usb-stick in the
server and install grub there?
Well, my first recommendation would have been turning off BIOS RAID -
but that seems not to work for you. (I've been running SuperMicro
servers for years, always turn off hardware RAID and rely on md - no
SSDs though).
Did a little googling and found this:
https://wiki.debian.org/DebianInstaller/SataRaid - which recommends
adding dmraid=true to the kernel boot line (see page for detailed
instructions).
You might get some good advice on the linux-raid email list. Also, I've
found the webhostingtalk.com forums to be a good source for
product-specific knowledge on various servers - supermicro tech support
is basically useless.
