戴尔i7设备Ubuntu与Windows 10双系统下Intel Optane Memory支持性咨询
Core Compatibility Breakdown
Let’s cut straight to the official facts: Intel explicitly does not support Optane Memory on any Linux distribution, including Ubuntu 17.10.1 running the 4.13 kernel. Their documentation clearly states the only supported environment is 64-bit Windows 10—no exceptions here.
Dual-Boot Scenario Realities
Even if you have a working Optane setup in your Windows 10 partition, don’t expect Ubuntu 17.10.1 to recognize or utilize it. Here’s why:
- Linux kernels (4.13 included) lack the specialized drivers and storage stack integration needed to communicate with Optane’s hardware-level caching logic.
- Optane’s core functionality relies on Windows-specific components like Intel Rapid Storage Technology (RST) that have no equivalent in Linux.
Dell i7 Device Specifics
For Dell systems equipped with an i7 processor, this limitation still applies across the board:
- The hardware itself works with Optane when booted into Windows 10, but once you switch to Ubuntu 17.10.1, the Optane module will either be invisible to the OS, or only function as a generic, unoptimized storage drive (not a performance-boosting cache).
- Dell’s official support docs align with Intel’s stance—they don’t offer Linux drivers or configurations to enable Optane caching for Ubuntu in dual-boot setups.
Practical Workaround (If You Need to Use Optane in Ubuntu)
If you want to repurpose the Optane module for Ubuntu storage, you can disable its caching functionality in your system’s BIOS/UEFI first, then format it as a standard volume. Just note that this will break Optane caching for Windows 10 until you re-enable the setting in BIOS/UEFI again.
