Or are they re-branded? Are they manufactured by HP, IBM, Cisco, etc.? Basic question, but I'm wondering whether they rebranded them as they do the Unified Communications' servers MCS series.
Cisco B-Series blade servers and C-Series rack servers are designed by Cisco. There are no 3rd party products therefore no re-branding. In Fact, there are a number of patents and new specifications that were put forth with the introduction of Cisco's servers.
