Latest storage status on Arm

on YouTube ↗24m

" summary

Status update lists concrete wins: SPDK enabled on aarch64 with both 4KB and 64KB kernel page sizes and upstream patches accepted in Ceph, SPDK and DPDK; ISA-L is extended to aarch64 providing CRC, SHA and AES primitives used by storage stacks. Microbenchmarks show CRC table code ~9x faster and CRC32 instructions up to ~15x versus generic, SPDK tests reach up to ~37x IOPS/bandwidth over kernel drivers, and Ceph with SPDK/DMA plus 64KB pages yields roughly 5–10% (sometimes >10%) throughput gains. Hardware NVMe, IOMMU and unit-test fixes are validated.
