Existing DFSs often consider remote storage a performance constraint, assuming it delivers lower bandwidth and higher latency than local devices. However, the advancements in RDMA technology present an opportunity to narrow the performance disparity between local and remote access, empowering DFSs to harness both local and remote I\/O capabilities, thereby attaining higher aggregated throughput.<\/jats:p>\n                  <jats:p>We propose SwitchFS, a new DFS architecture that exploits all the available PM bandwidth in a cluster with generative I\/O path assignment policy. It dynamically steers client-side I\/O requests to the local cache and the remote devices accessible through RDMA network. To determine the run-time I\/O path adaptively, we introduce MELON, an I\/O path selection policy based on a reinforcement learning model, designed to optimize expected I\/O latency. Meanwhile, SwitchFS adopts a model-driven opportunistic replication mechanism at the server-side, which further improves I\/O bandwidth utilization of remote devices across the cluster. Furthermore, we adopt the fine-grained concurrency control approach to improve scalability. Across synthetic and real-world application workloads, SwitchFS improves throughput by up to 5.9\u00d7 over existing DFS designs while preserving low tail latency and incurring modest learning overhead.<\/jats:p>","DOI":"10.1145\/3818684","type":"journal-article","created":{"date-parts":[[2026,5,26]],"date-time":"2026-05-26T11:41:57Z","timestamp":1779795717000},"page":"1-26","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["SwitchFS: Exploiting Persistent Memory Bandwidth in Cluster via Learning-based I\/O Path Selection"],"prefix":"10.1145","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8838-6064","authenticated-orcid":false,"given":"Zhenlin","family":"Qi","sequence":"first","affiliation":[{"name":"Department of Computer Science and Engineering, Shanghai Jiao Tong University","place":["Shanghai, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2485-760X","authenticated-orcid":false,"given":"Shengan","family":"Zheng","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Engineering, Shanghai Jiao Tong University","place":["Shanghai, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7526-8971","authenticated-orcid":false,"given":"Bowen","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Engineering, Shanghai Jiao Tong University","place":["Shanghai, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1531-7962","authenticated-orcid":false,"given":"Linpeng","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Engineering, Shanghai Jiao Tong University","place":["Shanghai, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"320","published-online":{"date-parts":[[2026,6,25]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1145\/3342195.3387522"},{"key":"e_1_3_2_3_2","first-page":"1011","volume-title":"Proceedings of the 14th  \\(\\lbrace\\) USENIX \\(\\rbrace\\)  Symposium on Operating Systems Design and Implementation","author":"Anderson Thomas E.","year":"2020","unstructured":"Thomas E.
