Hi, as title really, the H10 (https://www.intel.ca/content/www/ca/en/products/memory-storage/optane-memory/optane-memory-h10-solid... is optane with SSD built in, cant find part numbers on this page... !
You may use one - and only one - Optane device in a system. This can be an M10 Optane Module being used to accelerate the performance of a separate, SATA-based HDD or it can be a H10 Optane SSD, where the Optane portion of this drive is used to accelerate the performance of the SSD portion of this drive.
This page details the NUC models that support Optane modules: Installing Intel Optane Memory on Intel NUC Kits. Yes, the PN NUCs support this capability.
Hope this helps,
I presume you are referring to the use of an M10 Optane Memory Module to accelerate a HDD. A portion of the support for acceleration is implemented in the chipset (the PCH component). Since the M.2 ports are downstream of the PCH, the PCH is able to manage it and, to the O/S, make the combination look like a single drive. It does, however, require that the BIOS do some special remapping of the PCIe steering so that the PCH can manage it. This is very similar to Intel RST, which can only implement RAID0/RAID1 on NVMe SSDs if the BIOS does similar remapping.
Intel RST RAID and Intel Optane-based drive acceleration are implemented partially in hardware, partially in firmware (including BIOS) and partially in O/S-present software. While Intel is working to expand this, the software portion is currently only implemented for Windows. No support for Linux is yet available.
Hope this helps,
Linux will see the Optane portion of a H10 SSD as a separate small SSD. It will have no benefit other than that. Similarly, Linux will simply see the M10 Optane module as a small SSD.
Windows can use the M10 Optane module to accelerate the performance of a SATA-based SSD or HDD.
I'll add to Scott's posts the Intel Memory M and H Series Installation Guide and Frequently Asked Questions for Intel® Optane™ Memory page with additional information for your questions. There you may find all the necessary information.
