Their main difference lies in where they run and the scope of their functions.<\/span><\/p><p><span style=\"font-size: 14pt;\">The switch subnet manager is software that runs on the switch itself. It can automatically discover and configure devices in the network and provide basic network monitoring and diagnostic functions. It does not require additional management nodes, but it also does not support advanced network optimization and security functions.<\/span><\/p><p><span style=\"font-size: 14pt;\">The OFED subnet manager is software that runs on the host. It can use the subnet management service provided by OpenSM or Mellanox OFED. It can run on multiple hosts, achieving subnet manager redundancy and load balancing. It supports some advanced network functions, such as adaptive routing and congestion control, but it also does not support network security and preventive maintenance functions.<\/span><\/p><p><span style=\"font-size: 14pt;\">UFM is software that runs on dedicated management nodes. It is NVIDIA\u2019s unified network management platform. It can monitor and manage the InfiniBand network comprehensively, supporting various advanced network functions, such as adaptive routing, congestion control, network security, preventive maintenance, performance analysis, etc. It requires at least one management node and a UFM license.<\/span><\/p><p><span style=\"font-size: 14pt;\">Which one is more suitable for customers to choose depends on their needs and budgets. If customers only need basic network functions and do not want to add extra management nodes, they can choose the switch subnet manager. If customers need some advanced network functions and already have host nodes, they can choose the OFED subnet manager. If customers need the most comprehensive and advanced network functions and are willing to invest in dedicated management nodes and UFM licenses, they can choose UFM.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-4c0de13f e-flex e-con-boxed e-con e-parent\" data-id=\"4c0de13f\" data-element_type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-26393a1f elementor-widget elementor-widget-heading\" data-id=\"26393a1f\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">People Also Ask<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-4fe0a11c elementor-posts--thumbnail-none elementor-grid-3 elementor-grid-tablet-2 elementor-grid-mobile-1 elementor-card-shadow-yes elementor-posts__hover-gradient elementor-widget elementor-widget-posts\" data-id=\"4fe0a11c\" data-element_type=\"widget\" data-settings=\"{&quot;cards_columns&quot;:&quot;3&quot;,&quot;cards_columns_tablet&quot;:&quot;2&quot;,&quot;cards_columns_mobile&quot;:&quot;1&quot;,&quot;cards_row_gap&quot;:{&quot;unit&quot;:&quot;px&quot;,&quot;size&quot;:35,&quot;sizes&quot;:[]},&quot;cards_row_gap_tablet&quot;:{&quot;unit&quot;:&quot;px&quot;,&quot;size&quot;:&quot;&quot;,&quot;sizes&quot;:[]},&quot;cards_row_gap_mobile&quot;:{&quot;unit&quot;:&quot;px&quot;,&quot;size&quot;:&quot;&quot;,&quot;sizes&quot;:[]}}\" data-widget_type=\"posts.cards\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-posts-container elementor-posts elementor-posts--skin-cards elementor-grid\" role=\"list\">\n\t\t\t\t<article class=\"elementor-post elementor-grid-item post-20376 post type-post status-publish format-standard has-post-thumbnail hentry category-blog category-fiber-optic-transceivers\" role=\"listitem\">\n\t\t\t<div class=\"elementor-post__card\">\n\t\t\t\t<div class=\"elementor-post__text\">\n\t\t\t\t<h3 class=\"elementor-post__title\">\n\t\t\t<a href=\"https:\/\/www.fibermall.com\/blog\/qsfp112-price.htm\"  target=\"_blank\">\n\t\t\t\tQSFP112 Price Guide 2026: 400G Module Costs, Cost Per Port and Volume Tiering\t\t\t<\/a>\n\t\t<\/h3>\n\t\t\t\t<div class=\"elementor-post__excerpt\">\n\t\t\t<p>The same 400G DR4 optic can sell for around $500 from a factory-direct supplier and more than $1,400 from some vendor list price channels.
