The fatal flaw of blade servers

Disadvantages of blade servers: 1. Heat dissipation problem: dense configuration leads to overheating; 2. Reliability problem: compact components lead to reduced reliability; 3. Poor maintainability: small size makes it difficult to replace or upgrade components; 4. High power consumption: Tight configuration and additional components lead to higher electricity bills and environmental issues; 5. Higher cost: both initial cost and maintenance and upgrade costs are higher than rack-mounted servers.
