alt Hacker NewsI 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.
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.
