Blade servers are compact, modular computer servers designed to save space and improve efficiency in data centers. They consist of multiple server blades housed in a single chassis, allowing for easy management and scalability. Each blade operates independently but shares power, cooling, and networking resources, which reduces overall energy consumption. These servers are ideal for businesses that require high performance and flexibility without the bulk of traditional servers. By consolidating hardware, blade servers help organizations optimize their IT infrastructure, making it easier to deploy applications and manage workloads effectively.
