summary

Three generations of Alibaba Cloud Block Store evolve from a simple two-layer replica model to an SSD/RSBD plus Pangu backend and finally to a hardware-accelerated mixed-compress pipeline; EBS1 serves >1M disks, EBS2 scales to 500+ clusters and 2M disks with average read latency ~100µs, 1M IOPS and 4400 MB/s peak, and EBS3 uses accelerator cards and PMEM to cut space and network costs — space cost 3→0.69 and traffic amplification 4.69→1.59.
