I was looking into SSD caching recently and decided to go with Open-CAS instead, which should be more performant (didn't test it personally): https://github.com/Open-CAS/open-cas-linux/issues/1221
It's maintained by Intel and Huawei and the devs were very responsive.
I mean to ask a genuine, good faith question here, because I don't know much about Huawei's development team.
My head goes to the xz attack when I hear that Intel decided to stop supporting an open source tool, and a Chinese company known to sell backdoored equipment "steps in" to continue development, and it makes me suspicious & concerned.
This is to say nothing of the quality of the software they write or its functionality, they may be "good stewards" of it, but does it seem paranoid to be unsure of that arrangement?
Is Intel still working on it? Open-CAS bdev support was nearly removed from SPDK at a time when Intel still employed a SPDK development and QA team. Huawei stepped in to offer support to keep it alive, preventing its removal.
I’ve been under the impression that Intel got rid of pretty much all of their storage software employees.
