context_page_description: Cisco Unified Computing System' is a data center server computer product line composed of computing hardware, virtualization support, switching fabric, and management software introduced in 2009 by Cisco Systems.
  The products are marketed for scalability by integrating many components of a data center that can be managed as a single unit.
context_section_description: The UCS product line was announced in March and first installed in September 2009, at the customer premises of Tutor Perini. The first customer purchase of UCS was by Fiserv, a financial services customer in Milwaukee, Wisconsin.  The entire project was code named "California".
  The computing component of the UCS is available in two versions: the B-series (a powered chassis and full and/or half slot blade servers), and the C-series for 19-inch racks (that can be used with fabric interconnects). The computer hardware managed by the UCS Manager software on the fabric Interconnects can be any combination of the two. Both form factors use standard components, including Intel x86-64 processors and DIMM memory.  The servers are marketed with converged network adapters and port virtualization.
  Around 2010, an extended memory technology expanded the number of memory sockets that can be connected to a single memory channel in some models.
  A fifth generation was announced in July 2018.
