Red Hat is interested in supporting geo-replication of data in a Ceph instance, which requires the ability to take consistent, point-in-time, online snapshots of the complete distributed system. We propose and analyze an algorithm that uses time synchronization and transient write delays to implement this snapshotting feature while maintaining Ceph&#8217;s consistency and performance guarantees.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Red Hat Computer Science, 2014-15 Liaison(s): Ian Colle, Greg Farnum &#8217;09, Sam Just &#8217;10, Sage Weil &#8217;00 Advisor(s): Beth Trushkowsky [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[140],"tags":[280],"class_list":["post-12281","post","type-post","status-publish","format-standard","hentry","category-computer-science","tag-red-hat"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.hmc.edu\/clinic\/wp-json\/wp\/v2\/posts\/12281","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.hmc.edu\/clinic\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.hmc.edu\/clinic\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.hmc.edu\/clinic\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.hmc.edu\/clinic\/wp-json\/wp\/v2\/comments?post=12281"}],"version-history":[{"count":0,"href":"https:\/\/www.hmc.edu\/clinic\/wp-json\/wp\/v2\/posts\/12281\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.hmc.edu\/clinic\/wp-json\/wp\/v2\/media?parent=12281"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.hmc.edu\/clinic\/wp-json\/wp\/v2\/categories?post=12281"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.hmc.edu\/clinic\/wp-json\/wp\/v2\/tags?post=12281"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
