Alan Cox, former #2 Linux kernel developer, at G+, on the differences between Linux and Microsoft RAID support, related to recent Lenovo news,[1] and the technical and historical basis for this.
I did some massaging of the fourth paragraph, which seems closest to a lede/head, to fit within HN's 80 character headline limit. The first four 'graphs of the post:
"Unsupported models will rely on Linux operating system vendors releasing new kernel and drivers to support features such as RAID on SSD"
Good to see that the tech press fact check comments from companies as well as the political press fact check politicians. I'm reading this on a box with RAID1 SSD. It's had RAID1 SSD for some years.
Linux has supported RAID on SSD for years, in fact it supported it from the moment you could plug an SSD into a Linux PC.
Linux RAID is different from much of the Windows experience, for a mix of sound technical reasons and historical ones.
After looking at the gossamer thread: Could this be directly related to the current BIOS problems? Lenovo's closed source driver runs into problems -> Lenovo dev wants to commit workaround to Linux, fails -> force different PCI-ID as alternate workaround by crippling the BIOS? Firmware gets copy&pasted to non-servers?
