Blade Servers20A blade server is basically a modular, configurable server requiring a blade enclosure or chassis (which perform additional computing functions) structured to increase power and cooling efficiency, and importantly take up less physical space while not sacrificing computing power.Cisco UCS B-Series1https://media.trustradius.com/vendor-logos/KP/BJ/EKH5RFTLCO4X-180x180.PNGHPE BladeSystem2https://media.trustradius.com/vendor-logos/qq/uK/ZTECRXT03ME3-180x180.JPEGLenovo Flex System Blade Servers (formerly IBM BladeCenter)3https://media.trustradius.com/vendor-logos/LR/zp/V0HPUC83UP3G-180x180.JPEGBull Blade Servers4https://media.trustradius.com/vendor-logos/sw/yj/WVTZRS90JXC0-180x180.jpgSupermicro SuperBlade5https://media.trustradius.com/vendor-logos/vO/av/1QTLGDZMGXL4-180x180.JPEGNEC Sigmablade-M6https://media.trustradius.com/vendor-logos/V7/VJ/1803CSTL26SA-180x180.PNGColocation America7https://media.trustradius.com/product-logos/9Z/oC/7XXJFTL9CAQM.PNGHitachi Compute Blade (BladeSymphony)8https://media.trustradius.com/vendor-logos/vI/2c/IFDUXHPZ281G-180x180.PNGFujitsu Primergy BX Series9https://media.trustradius.com/vendor-logos/aI/FW/KB0LL6HPRJKM-180x180.JPEGHPE SGI 8600 System10https://media.trustradius.com/vendor-logos/qq/uK/ZTECRXT03ME3-180x180.JPEGHPE Integrity Superdome X11https://media.trustradius.com/vendor-logos/qq/uK/ZTECRXT03ME3-180x180.JPEGHPE Integrity NonStop12https://media.trustradius.com/vendor-logos/qq/uK/ZTECRXT03ME3-180x180.JPEGHPE Integrity13https://media.trustradius.com/vendor-logos/qq/uK/ZTECRXT03ME3-180x180.JPEGIntel MFSYS2514https://media.trustradius.com/vendor-logos/Ew/IS/Q672JHANLJ3S-180x180.JPEGOracle Sun Blade 600015https://media.trustradius.com/vendor-logos/VC/02/T4E108T4IWP2-180x180.PNGNEC Sigmablade-H16https://media.trustradius.com/vendor-logos/V7/VJ/1803CSTL26SA-180x180.PNGDell PowerEdge M17https://media.trustradius.com/vendor-logos/xW/Gb/SGTVSU5KIT5G-180x180.JPEGOracle Netra Modular System18https://media.trustradius.com/vendor-logos/VC/02/T4E108T4IWP2-180x180.PNGSupermicro MicroBlade19https://media.trustradius.com/vendor-logos/vO/av/1QTLGDZMGXL4-180x180.JPEG

Blade Servers Overview

What are Blade Servers?

A blade server is a data center server module designed to fit a blade enclosure or chassis which performs ancillary functions. These include power supply and management, cooling, and some networking. The blades are designed to increase a data center’s overall power and cooling efficiency, and take up less physical space than alternatives.


Blade servers are scalable, and often hot-swappable. Blade systems include servers and chassis and are designed to support a wide variety of business objectives. These may include virtualization, web hosting, file storage and sharing, and other needs.

Blade Server Benefits & Capabilities

Blade server modules and blade server systems provide the following advantages:

  • Lean form factor & high space saving

  • Less need for cables

  • Less need for switches and network interface cards or adapters

  • Lower cost of power, cooling

  • Module hot swapping

  • Highly scalable architecture

  • Specialized modules (compute, storage, network)

  • Diskless or virtualization modules

  • Configurable via software management interface

  • Buy all needed components from a single vendor

  • White box servers may be available (low cost)

Pricing Information

Blade server modules and chassis are available on perpetual licenses. However, support is likely available on subscription (e.g. 3-year, or 5-year). Blade systems including modules and chassis may all be purchasable from a single vendor. Purchases are scalable with acquisition of additional blades. These modules may specialize in compute, storage, or networking as needed. White box servers may also be available, as a lower cost option. However, blade servers do come with a great risk of vendor lock-in. Modules are often designed to function with chassis from the same vendor. Switching vendors can be an expensive proposition requiring data center overhaul.
