What are blade servers?

Blade Servers… MORE POWER. MORE BACKUP. LESS SPACE.

  • A server architecture that houses multiple server modules (blades) in a single housing unit (chassis)
  •  Used in datacenters to save space and improve system management  
  •  Chassis provides the power supply, cooling, storage and connectivity

Blade Properties

  • CPU, memory and hard disk +/- redundant power
  • Management systems +/- network or storage switch
  • Essential processing and services
  • May provide storage, system management for the chassis or even for wider network
  • Blade enclosure, which can hold multiple blade servers, provides services such as the power, cooling, networking, various interconnects and management. Together, blades and blade enclosure form the blade system.

 

Thin Client Computing

The blade server model promotes thin-client computing, where in an enterprise environment workers can log on to their computer from remote terminals. At their office space, the worker has access to standard input and output functionality through keyboard, mouse and monitor. However, their PC is a blade (often termed a “PC blade”) held in a chassis, stored in a central, secure location, with centralised management and maintenance. In a wireless setting, they can work on their PC from anywhere in range. If the workplace’s network is accessible over the Internet, perhaps through a VPN (Virtual Private Network), then the worker can access their PC from anywhere they have access to a client computer and the web.
