Is Intel Optane supported?

Hello all. My first post and first time wading into the EOS/arch waters. Be patient with me please as I am sure you will be seeing lots of posts from me. LOL

The short version of my question is can Intel Optane be configured during the EOS installation process? I have only have been able to find passing references to it in the community. But may have missed something.

The long version…

I know it is a different Distro but according to this thread, it seems that it can be done in Linux. (See:

But, unless I am misunderstanding, it indicates that Dual Boot boxes aren’t supported.

Be aware: Since there is no support for RST’s caching with Optane memory in Linux, you can’t dual boot Windows with RST caching configured, and Linux. Either turn of Optane in Windows or put Windows into a VM in the Linux OS. To make things not complicated, the following won’t consider dual boot.

But, Intel seems to indicate that it may be possible. They recommend using the open source MD RAID package which they contribute to as well.

Are RST and MD RAID mutually exclusive? By that I mean can I leave RST in place (ie BIOS) for booting into WIn10 and somehow configure MD RAID to be used?

The vmd module is present to boot systems with Raid. You have to turn RST off and set the drives to AHCI and not raid in UEFI Bios.

You can run dual boot with Windows this way and Windows will be running with drives in AHCI mode also.

Here is some info on the two types of Raid but i personally don’t recommend even going there at this stage. It’s fairly complex for a new user and I’m no expert on setting up software raid or fake raid as they call it.

Optane and RST are not the same thing.
