Keynote: Pushing the Limits of Ceph Performance through Software & Hardware Innova...
summary
Intel describes concrete upstream work: SPDK/DPDK and PMDK backends for SSDs are under development, BlueStore and Rocks improvements land, and Seastar-based deep I/O primitives are merged. A single-threaded Crimson OST boots and client-side bidirectional cache with read-only and write-back modes nears upstream merge. New hardware tests show QLC 30 TB SSDs and persistent memory enabling about 70% better performance at similar cost and combined software+hardware stacks reaching as much as 3.5x throughput in reference configs.
