RAID function for PCIe mode SSD in Intel Rapid Storage Technology is available with either 1. Intel SSDs installed in both CPU-attached and PCH-attached slots, or 2. any other 3rd party SSDs installed in PCH-attached slots.
To enable Intel Optane Memory (Hybrid Storage device), it must be installed in PCH-attached slots with Intel Rapid Storage Technology.
* M.2_2 slot shares bandwidth with PCIEX16_1 and PCIEX16_2. When M.2_2 runs x4 mode, PCIEX16_1 will run x8 mode and PCIEX16_2 will run x4 mode.
** When DIMM.2_1 is operating in SATA mode, SATA6G_2 will be disabled.
*** SATA6G_56 shares bandwidth with PCIEX4 slot. When SATA6G_56 is populated, PCIEX4 slot will run x2 mode and SATA6G_56 will be disabled when PCIEX4 slot runs x4 mode.
