Cisco brings the power of UCS in a smaller form factor for smaller business, remote, and branch offices with the UCS Mini solution, a combination of blade and rack servers with unified management provided by Cisco UCS Manager. UCS Mini is compact version with  the specialized 6324 Fabric Interconnect model embedded into the Cisco UCS blade chassis for a smaller server footprint. It provides servers, storage, network, and management capabilities similar to classic UCS. The 6324 Fabric Interconnect combines the Fabric Extender and Fabric Interconnect functions into one plugin module to provide direct connections to upstream switches. A pair of 6324 Fabric Interconnects will be directly inserted into the chassis, called the primary chassis, and provide internal connectivity to UCS blades. A Fabric Extender is not required for the primary chassis. The primary chassis can be connected to another chassis, called the secondary chassis, through a pair of 2208XP or 2204XP Fabric Extenders.

Cisco UCS Mini supports a wide variety of UCS B-Series servers, such as B200 M3, 200 M4, B420 M3, and B420 M4. These blades can be inserted into mixed form factors. UCS Mini also supports connectivity to UCS C-Series servers C220 M3, C220 M4, C240 M3 and C240M4. A maximum of seven C-Series servers can be connected to a single chassis. It can support a maximum of 20 servers with a combination of two chassis with eight half-width blades per chassis and four C-Series servers.
