Developers placed complete microcomputers on cards and packaged them in standard 19-inch racks in the 1970s soon after the introduction of 8-bit microprocessors.
This architecture operated in the industrial process control industry as an alternative to minicomputer control-systems.
Varajased mudelid hoidsid programme EPROM-mälus ja olid piiratud ühe funktiooni üheaegse sooritamisega.
 
VMEbus arhitektuur (ca. 1981) defineeris arvuti a computer interface which included implementation of a board-level computer installed in a chassis backplane with multiple slots for pluggable boards to provide I/O, memory, or additional computing.
The PCI Industrial Computer Manufacturers Group PICMG developed a chassis/blade structure for the then emerging Peripheral Component Interconnect bus PCI which is called CompactPCI.
Common among these chassis based computers was the fact that the entire chassis was a single system.
While a chassis might include multiple computing elements to provide the desired level of performance and redundancy, there was always one board in charge, one master board coordinating the operation of the entire system.
 
PICMG expanded the CompactPCI specification with the use of standard Ethernet connectivity between boards across the backplane.
The PICMG 2.16 CompactPCI Packet Switching Backplane specification was adopted in Sept 2001 (PICMG specifications).
This provided the first open architecture for a multi-server chassis.
PICMG followed with the larger and more feature-rich AdvancedTCA specification targeting the telecom industry's need for a high availability and dense computing platform with extended product life (10+ years).
While AdvancedTCA system and boards typically sell for higher prices than blade servers, AdvancedTCA suppliers claim that low operating-expenses and total-cost-of-ownership can make AdvancedTCA-based solutions a cost-effective alternative for many building blocks of the next generation telecom network.
 
Esimese kasutajatele mõeldud blade-serveri arhitektuuri leiutajateks on Christopher Hipp ja David Kirkeby ja nende patent US 6411506 anti Houstonis asetsevale RLX Tecjnologies'le. Firma koosnes peamiselt endistest Compaq Computer Corp töötajatest, sealhulgas Hipp ja Kirkeby. RLX müüs esimes blade-serveri 2001. aastal ja 2005. aastal osteti firma HP poolt ära.
 
Veebruaris 2006 avatirajati Blade.org, et suurendada erinevate blade-lahenduste saadaolevust ja kiirendada nende turuletoomist. Tegu on koostööl põhineva organisatsiooni ja arendajate ühinguga focused on accelerating the development and adoption of IBM blade server platforms.
 
The name blade server appeared when a card included the processor, memory, I/O and non-volatile program storage (flash memory or small hard disk(s)).
This allowed manufacturers to package a complete server, with its operating system and applications, on a single card / board / blade.
These blades could then operate independently within a common chassis, doing the work of multiple separate server boxes more efficiently.
In addition to the most obvious benefit of this packaging (less space-consumption), additional efficiency benefits have become clear in power, cooling, management, and networking due to the pooling or sharing of common infrastructure to supports the entire chassis, rather than providing each of these on a per server box basis.
 
Uuringufirma IDC andmetel<ref>http://www.idc.com/getdoc.jsp?containerId=prUS21989209</ref> on suurimad tootjad blade-serverite turul HP, IBM ja Dell. Teised blade-lahendusi pakkuvad firmad on AVADirect, Sun, Egenera, Supermicro, Hitachi, Fujitsu-Siemens, Rackable (Hybrid Blade), Verari Systems and Intel.
