The prominent brands in the blade server market are [[Supermicro]], [[Cisco Systems]], [[Hewlett Packard Enterprise|HPE]], [[Dell]] and [[IBM]], though the latter sold its [[x86]] server business to [[Lenovo]] in 2014 after selling its consumer PC line to Lenovo in 2005.<ref name="IBM Lenovo">{{cite web|title=Transitioning x86 to Lenovo|url=http://www-03.ibm.com/systems/infrastructure/us/en/it-infrastructure/lenovo-acquisition.html|archive-url=https://web.archive.org/web/20140405051227/http://www-03.ibm.com/systems/infrastructure/us/en/it-infrastructure/lenovo-acquisition.html|url-status=dead|archive-date=April 5, 2014|website=IBM.com|access-date=27 September 2014}}</ref>

In 2009, Cisco announced blades in its [[Cisco Unified Computing System|Unified Computing System]] product line, consisting of 6U high chassis, up to 8 blade servers in each chassis.
