Senior🎓
Top SchoolJoseph Qi is a senior technical expert with 13 years of experience in Linux kernel, storage virtualization, and cluster filesystems, currently leading IO QoS work at Alibaba Cloud. He has deep hands-on expertise in blkio controllers, IO throttling, proportional weight scheduling, and implemented per-cgroup latency and weight controls as well as directory-level IO upper limits for ext4. Previously he led cluster filesystem and storage virtualization efforts at Huawei, contributing over 80 patches to the Linux kernel (OCFS2 and related areas). Comfortable bridging low-level kernel engineering and system architecture, he also has background in virtualization tech (Xen/KVM), multipath, and RAMCloud. Based in Hangzhou, he combines a pragmatic, results-driven approach with a track record of upstream open-source contributions. Notably, his work enables finer-grained IO policies within cgroups—an uncommon capability that improves multi-tenant storage fairness and performance.
