The discard option is not used for the Optane-based device, since Optane Memory works in a different way than flash memory and so won’t need discards. Now add the line for nvme1n1_crypt, using the UUID from the last step. There should be already one line for the device nvme0n1p3_crypt. This information is essential for booting the system. The purpose of /etc/crypttab is to hold a list of encrypted devices. Sudo vgextend ubuntu-vg /dev/mapper/nvme1n1_crypt # Add the LUKS device to the existing volume group: Sudo cryptsetup luksOpen /dev/nvme1n1 nvme1n1_crypt When you have successfully booted into your new system, the next step is to configure the LUKS encryption layer: # Setup the LUKS container holding the crypted Optane Memory: LVM delivers the logical volumes for swap and root. Nvme0n1p1 holds /boot/efi, nvme0n1p2 holds /boot, and nvme0n1p3 holds a LUKS container, which is used by LVM as physical device for the volume group ubuntu-vg. So in the installer, these are the selections:Īfter installation, the resulting disk layout is quite simple: Device Start End Sectors Size Type LVM is mandatory for the latter steps, encryption optional, but assumed to be enabled. Start with a conventional installation, use the complete SSD (/dev/nvme0n1) with LVM and LUKS Encryption. To make things not complicated, the following won’t consider dual boot. Either turn of Optane in Windows or put Windows into a VM in the Linux OS. But in Linux we will do that without RST, so no need for that options.īe 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. These options are intended for the RST-driver to recognize a device constructed of the two components. Have a look in the option ROM of the controller too, to make sure there is no combined device anymore. So the first step is to disable the BIOS option "Advanced / System options / Configure Storage Controller for Intel Optane". These devices are mapped as /dev/nvme0 and /dev/nvme1, and because of nvme technology, the usable blockdevices are /dev/nvme0n1 and /dev/nvme1n1 (aka nvme namespaces). On the physical layer, the device splits up into two independent nvme devices: lspci | grep "Non-Volatile"Ġ2:00.0 Non-Volatile memory controller: Intel Corporation Device 0975 (rev 03)Ġ3:00.0 Non-Volatile memory controller: Intel Corporation Device 0975 So I wanted to use the Optane Memory as cache too, like the Windows people do. Many people on the net suggest to use it as an independent, fast, but also small disk.īut my workloads vary, and I don’t want to waste time deciding what to put on Optane and what to put on flash. However, using the Optane Memory isn’t that hard. #INSTALL WINDOWS ON OPTANE DC PERSISTENT MEMORY DRIVER#But in Linux? No driver support from Intel for that. Its easy for Windows users – there is the preinstalled Intel RST-Driver, which setups the Optane memory as cache for the SSD. That cache is build up of Optane memory, which is slower than DRAM, but faster than flash memory, and non volatile too. It is a solid state disk with an additional non volatile cache memory. The machine is equiped with an "INTEL® OPTANE™ MEMORY H10 WITH SOLID STATE STORAGE". And here comes his story to enable Intel Optane using Ubuntu.Īddicted to Linux, the decision was clear to purge Windows and to setup Ubuntu, currently 18.04 LTS. Recently Michael from Opvizor ordered a new laptop – a HP ProBook 650 G5. #INSTALL WINDOWS ON OPTANE DC PERSISTENT MEMORY HOW TO#How to use Intel Optane Memory for SSD Caching
