ARC(4)

💅 ARC(4) — like, the Kernel Interfaces Manual bestie 🎀

arc — the Areca Technology Corporation SAS/SATA RAID controller driver. no cap, that's the whole name. short, iconic, does exactly what it says 🫶

🌸 SYNOPSIS 🌸

arc* at pci?

that's it. that's the whole config line. arc* attaches at pci? and honestly the way that just works is so satisfying 🦋

like, the range? the drama? we love a controller family with range 👑

and these controllers can support RAID levels 0, 1, 1E, 3, 5, 6, and JBOD. yes bestie, 1E is in there, and yes JBOD counts as a level here, don't come for me, that's what the page says 💀

arc also supports alarm control and monitoring of volumes configured on the controllers, and it does it through the bio(4) interface and the bioctl(8) utility. so you get to actually see what's going on instead of just vibing and hoping 🧚

lowkey important: this page is from the Debian build of the manpage, dated January 24, 2014, and it lives in the ARC(4) slot of the Kernel Interfaces Manual — so when you cite it, cite it proud 💅✨

okay that's the whole page, you're officially an arc expert now, go forth and RAID responsibly 🍓🎀
