In this article, we propose TeRM to extend RDMA-attached memory with SSD. TeRM achieves fast remote access on the SSD-extended memory by eliminating page faults of RDMA NIC and CPU from the critical path. We also introduce a set of techniques to reduce the consumption of CPU and network resources. Evaluation shows that TeRM performs close to the performance of the ideal upper bound where all pages are pinned in the physical memory. Compared with existing approaches, TeRM significantly improves the performance of unmodified RDMA-based storage systems, including a file system and a key-value system.<\/jats:p>","DOI":"10.1145\/3700772","type":"journal-article","created":{"date-parts":[[2024,10,21]],"date-time":"2024-10-21T10:56:36Z","timestamp":1729508196000},"page":"1-27","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Efficiently Enlarging RDMA-Attached Memory with SSD"],"prefix":"10.1145","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2031-5937","authenticated-orcid":false,"given":"Zhe","family":"Yang","sequence":"first","affiliation":[{"name":"Tsinghua University, Beijing, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5526-7154","authenticated-orcid":false,"given":"Qing","family":"Wang","sequence":"additional","affiliation":[{"name":"Tsinghua University, Beijing, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7924-9268","authenticated-orcid":false,"given":"Xiaojian","family":"Liao","sequence":"additional","affiliation":[{"name":"Tsinghua University, Beijing, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6214-5390","authenticated-orcid":false,"given":"Youyou","family":"Lu","sequence":"additional","affiliation":[{"name":"Tsinghua University, Beijing, China"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-5496-5522","authenticated-orcid":false,"given":"Keji","family":"Huang","sequence":"additional","affiliation":[{"name":"Huawei Technologies Co Ltd, Shenzhen, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7362-2789","authenticated-orcid":false,"given":"Jiwu","family":"Shu","sequence":"additional","affiliation":[{"name":"Tsinghua University, Beijing, China"}]}],"member":"320","published-online":{"date-parts":[[2025,2,8]]},"reference":[{"key":"e_1_3_2_2_2","volume-title":"4th USENIX Workshop on Hot Topics in Storage and File Systems (HotStorage\u201912)","author":"Zheng Da","year":"2012","unstructured":"Da Zheng, Randal Burns, and Alexander S.
