Introducing Tencent Cloud CBS Enhanced and Ultra‑Fast SSD Cloud Disks: Architecture and Performance Optimizations
Tencent Cloud’s new CBS 3.0‑based Enhanced and Ultra‑Fast SSD cloud disks cut latency by over 50 % to sub‑100 µs, boost IOPS up to 1.1 million and throughput to 4 GB/s, and achieve these gains through SPDK‑driven virtualization, RDMA‑based data paths, a user‑space ZTCP stack, zero‑copy memory handling and dedicated hardware acceleration, targeting latency‑sensitive and IO‑intensive workloads such as large databases, video processing and AI inference.
