What is equipment redundancy?<\/h2>\n

Equipment redundancy is a reliability engineering technique that helps a system to perform without interruption even when a piece of equipment fails.\u00a0<\/span><\/p>\n

Imagine two identical machines working simultaneously, sharing the load. Both machines are ready to take over the complete load in the event their counterpart fails. This ensures that there is no visible disruption in the operation even if one of them suddenly stops working.<\/span><\/p>\n

Equipment redundancy is used across many industries, especially those that have high <\/span>availability<\/span><\/a> and reliability requirements:<\/span><\/p>\n

Manufacturing example<\/b><\/p>\n

In cooling systems, two compressors of the same specifications are run simultaneously where one would have been sufficient. This ensures that at least one compressor is functional at all times. Since the compressors share the load, their <\/span>useful life is also prolonged<\/span><\/a>.<\/span><\/p>\n

IT example<\/b><\/p>\n

In computing architecture, the same data is stored in multiple locations. When one of the locations goes offline, the data will be available from the other location. The data is constantly synchronized across locations. This geographical system redundancy ensures data is available round the clock. IT applications and other resources are also replicated at different locations for redundancy, not just data.<\/span><\/p>\n

Automotive example\u00a0<\/b><\/p>\n

The tail light assembly for cars and most other automobiles have two sets of brake lights. One brake light is sufficient to inform other motorists that the automobile will be slowing down. But there are two sets to ensure that at least one brake light functions when the other fails.<\/span><\/p>\n

Airline example<\/b>\u00a0<\/span><\/p>\n

Twin-engine airplanes have redundant engines. In the event one of the engines fails, the other engine is powerful enough to safely land the aircraft at the nearest airport.<\/span>[\/vc_column_text][\/vc_column][\/vc_row][vc_row content_placement=”middle” kd_background_image_position=”vc_row-bg-position-bottom” kd_top_separator_style=”skew-left” kd_top_separator_height=”separator-height-small” kd_bottom_separator_style=”skew-left” kd_bottom_separator_height=”separator-height-small” kd_top_separator=”true” kd_bottom_separator=”true” css=”.vc_custom_1682969636891{margin-bottom: 40px !important;padding-top: 120px !important;padding-right: 40px !important;padding-bottom: 50px !important;padding-left: 40px !important;background: #dde4e8 url(https:\/\/limblecmms.com\/wp-content\/uploads\/cta-laired-hex-4.webp?id=9077) !important;background-position: center !important;background-repeat: no-repeat !important;background-size: cover !important;border-radius: 0px !important;}” css_tablet_landscape=”.vc_custom_1682969636891{padding-bottom: 80px !important;}” css_tablet_portrait=”.vc_custom_1682969636891{padding-bottom: 80px !important;}” css_mobile=”.vc_custom_1682969636892{padding-bottom: 80px !important;}”][vc_column][vc_row_inner kd_background_image_position=”vc_row-bg-position-top”][vc_column_inner]

What does \u2018fully redundant\u2019 mean?<\/h2>\n

When equipment or system is replicated completely and both run in parallel, we can say that the system is fully redundant.\u00a0<\/span><\/p>\n

Consider an industrial application that requires 2000 W of electrical power that has to be supplied using a Power Supply Unit (PSU). When two PSUs, both with 2000 W power capacity, are used \u2013 and each delivers 1000 W \u2013 the system is fully redundant.\u00a0<\/span><\/p>\n

The main unit and the redundant unit are identical in all aspects and share the load equally when both are functional. When one of the PSUs fails, the other will be able to deliver the complete requirement of 2000 W.<\/span><\/p>\n

Some systems might even run three (triple modular redundancy) or even four units (quadruple modular redundancy) to be extra safe. As you can imagine, that is very rare as it triples or quadruples your system\u2019s costs. <\/span>[\/vc_column_text][\/vc_column][\/vc_row][vc_row kd_background_image_position=”vc_row-bg-position-top” css=”.vc_custom_1687440273251{margin-top: 40px !important;}” el_class=”limble-page-blog-width”][vc_column][vc_column_text]<\/p>\n

The difference between standby, backup, and redundant equipment<\/h2>\n

Standby, backup, and redundancy may sound similar. There is a reason for that. All three are ways to improve system reliability. In all three modes, extra units of equipment are available to take over after equipment failure.\u00a0<\/span><\/p>\n

The differences are found in their operational configurations:\u00a0<\/span><\/p>\n
