You do not lose information during transfer. This lossless design keeps your storage safe and reliable.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" >What devices can you connect with Fibre Channel?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">You can connect servers, storage arrays, tape libraries, and backup devices. Fibre Channel lets you build a strong network for many types of storage hardware.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" >What is zoning in Fibre Channel?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Zoning controls which devices can talk to each other in your SAN. You use zoning to improve security and manage data paths. It helps keep your network organized.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" >What speeds does Fibre Channel support?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Fibre Channel supports many speeds, from 1 Gbps up to 128 Gbps. You pick the speed that matches your needs. Faster speeds help you move more data in less time.<\/p>","protected":false},"excerpt":{"rendered":"<p>Fibre Channel is a high-speed, lossless protocol for reliable data transfer between servers and storage in SANs and data centers.<\/p>","protected":false},"author":1,"featured_media":5106,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[26],"class_list":["post-5108","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-knowledge-center","tag-optics-transceivers"],"blocksy_meta":[],"acf":[],"_links":{"self":[{"href":"https:\/\/lp.szlogic.cn\/ru\/wp-json\/wp\/v2\/posts\/5108","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/lp.szlogic.cn\/ru\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/lp.szlogic.cn\/ru\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/lp.szlogic.cn\/ru\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/lp.szlogic.cn\/ru\/wp-json\/wp\/v2\/comments?post=5108"}],"version-history":[{"count":2,"href":"https:\/\/lp.szlogic.cn\/ru\/wp-json\/wp\/v2\/posts\/5108\/revisions"}],"predecessor-version":[{"id":7657,"href":"https:\/\/lp.szlogic.cn\/ru\/wp-json\/wp\/v2\/posts\/5108\/revisions\/7657"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/lp.szlogic.cn\/ru\/wp-json\/wp\/v2\/media\/5106"}],"wp:attachment":[{"href":"https:\/\/lp.szlogic.cn\/ru\/wp-json\/wp\/v2\/media?parent=5108"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/lp.szlogic.cn\/ru\/wp-json\/wp\/v2\/categories?post=5108"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/lp.szlogic.cn\/ru\/wp-json\/wp\/v2\/tags?post=5108"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
