RS and XOR EC are definitely useful features for an object store that's storing from like tens of petabytes to exabytes worth of data but for a remote block device with a typical size up to a couple dozen terabytes I'm not so sure. Thanks for the link I will check it out
Edit: skimmed it, classic AI "analysis" - totally ignores all the crap io_uring went through
Slow, buggy and resource hungry. Faster spdk-based engine rewrite has been on the way for like 7 years now
One cool feature of ceph is reed solomon erasure coding, myastor only does replication if storage efficiency is important
4+2 Erasure Coding has only half the storage overhead of 3x replication but the same fault tolerance
Also re spdk
