Setting up Intel RST on Ubuntu 12.10
I want to know if it is possible to set up caching using my notebooks mSSD that runs ubuntu 12.10 and Win 7 on the HDD. I use ubuntu much more and would prefer to cache files that it uses rather than cache windows. I found this PDF on the intel site that says it is possible. I want to know if anyone has done this? How did you manage it? If there is a tutorial somewhere then please do point me to it.

The SSD caching capabilities in the current generation of Intel’s RST (on the H77, Q77 and Z77/Z79 chipsets) can only be used through the Windows driver. Linux support, as noted by the PDF, is provided by the native Linux tools. There is no separate Intel-provided driver for RST on Linux.
For SSD caching on Linux, you should look at Linux-native solutions like flashcache or bcache. See also, flashcache & bcache benchmarking.
Hey thanks. Had come accross both flashcache and bcache and they can do the job, but have you tried to do this? Do you have any idea how? Also, would you have any idea how to use the native linux tools (MD RAID is actually intel supported) for setting up something like RST?
With regards to using mdadm to manage an RST array, I haven’t actually needed to do so yet. I have about 30 systems running RST RAID 1, most are running Windows, and I’ve only ever needed to worry about managing or rebuilding an array once or twice in the past few years. Last time I tried was with a very old distribution with only dmraid support instead of md support.
Wow thanks for this, I’ve been looking for a Linux-compatible alternative to Intel’s RST for a little while. This is particularly interesting since it doesn’t require a particular chipset to function!
I have been looking for this for a very long while — and was starting to think of switching back to Windows if there wasn’t anything. Thanks for keeping me on Linux!
Intel RST и установка linux
Всем привет! Сразу прошу прощения, что создаю очередную тему с вопросом, который уже обсуждался, но решения, подходящего мне, я не нашел. У меня 2 nvme ssd диска собраны в raid1 на контроллере intel RST, в биосе соответственно стоит режим RST, ACHI поставить нет возможности. И я пробовал поставить разные дистры и не один linux дистр диски и разделы на них не видит, а вот freeBSD увидела и диски и раздел и без проблем встала, но я хочу именно linux систему. И ситуация с BSD вселяет надежду, что можно сделать это и с linux ядром, может кто-то подскажет или направит где почитать?
Linux ставлю рядом с виндой, пока только изучаю систему и полностью отказываться от виндоус не готов, поэтому пересобрать рейд в mdadm не вариант.
Это тебе знак свыше. Не юзай Linux, FeeeBSD — все что тебе нужно 😀
Разбери этот «массив», жизнь сразу станет проще. Если не хочешь, то читай документацию mdadm, там есть поддержка этого говна.

Странное творится в твоей голове.
Расскажи, как ты пришёл к такому неестественному выводу?
Вывод вполне естественный, если вспомнить, откуда приходит во FreeBSD поддержка многих устройств.
В основном видеокарт, всяких вайфаев и прочего ненужного десктопного. А raid это как раз серверное, линуксу не нужно.
Workaround to Install Ubuntu 20.04 with Intel RST systems
I tried to install Ubuntu 20.04 in my Dell G5 which has 2 drives. One with Windows 10 on it (256 GB) and another one with 1 TB capacity. I shrunk the volume of 1 TB by 150 GB and tried to install there. But Ubuntu installer didn’t allow me as I got a dialog after the Keyboard setting said «Turn Off RST» with the message
This computer uses Intel RST (Rapid Storage Technology). You need to turn off RST before installing Ubuntu. For instructions, open this page: help.ubuntu.com/rst
If I make any changes in the BIOS setting, like changing the Intel controller from RAID to AHCI, Windows won’t boot and goes into System Recovery. I didn’t have this issue when installing 18.04. While creating the partitions, you need to create a EFI partition with 200 — 500 MB with the usual steps and the installation will be completed succesfully. On restarting, you will not be getting the GRUB but instead Ubuntu will boot by default. If you need to boot Windows, you will have to go to the BIOS and choose from the UEFI boot option each time. Once 18.04 installation is complete, you can upgrade it to 20.04. After upgrading I installed the KDE desktop and at the login screen I chose the «Ubuntu on Wayland» option. After doing these 2 things, I lost the new features of 20.04 like the Ubuntu boot screen with Dell logo and the power off/log out blur effect screen. Not sure how to get that back.
