From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Bcachefs making progress towards getting included in the kernel. My dream of having a Linux native RAID5 capable filesystem is getting closer to reality.

I have a pretty strong usecase for distributed Small/Medium Business bare metal VM hosts. most locations do not need NAS/SAN, and DAS will more than suffice. lower cost hardware with a near-line raided backend and SSD hotcache at FS level seems to be a pretty decent sweet spot.

obviously this is not some enterprise grade setup and YMMV, but I am pretty interested in a all-in-one FS solution. I am sure others may have more innovative setups where its even more interesting.

Sounds like a great use case.

I'm assuming your nearline drives speak SAS? Are you doing redundant controllers on the backplane for multipathing and for fault tolerance? I'm not sure if bcachefs specifically supports it (or if that would happen at a different layer) but distros in general should support it.

TCO gets split into CAPEX and OPEX, so you come out ahead on the initial purchase even though it uses more power in the long run, which surely looks better to the business.
