Dear frufru,
Thanks for your interest in StarWind solution.
You can read it in our KB article : https://knowledgebase.starwindsoftware. ... sh-arrays/
I would recommend to put your NVMe to software RAID-1 to avoid any troubles device if your NVMe will fail.
Regarding the size:
We recommend to specify 10% of total capacity StarWind device. So if we have 1 TB of StarWind device we need to specify 100 GB of L2 cache.
Thanks,
Ivan
