Blade server

A blade server is a compact, modular server designed to operate alongside multiple server modules within a shared enclosure known as a blade chassis. The individual server units share central components such as power supplies, cooling and network connectivity. This architecture enables organisations to operate substantial computing capacity within a limited amount of physical space. Blade servers are primarily used in data centres and larger IT infrastructures where scalability, centralised management and high server density are required. Depending on the chassis, additional server modules can be added or replaced relatively easily. Leading blade server systems are available from manufacturers including HPE, Dell and Cisco.
