Which of the following Cisco UCS servers are typically installed directly in a rack?
- B-Series servers
- UCS Mini servers
- C-Series servers
- E-Series servers
- M-Series servers
Of the available options, Cisco Unified Computing System (UCS) C-Series servers are typically installed directly in a rack. Cisco UCS C-Series servers are rack-mount standalone servers that can operate either with or without integration with Cisco UCS Manager. Therefore, Cisco UCS C-Series servers do not require a UCS fabric. For administrators who are more familiar with traditional Ethernet networks than UCS Fabric Interconnect, C-Series servers will most likely be simpler to deploy and feel more familiar than other Cisco UCS server products.
Cisco UCS B-Series servers are blade servers that are installed in a UCS blade chassis. These blade servers can connect only to Cisco UCS Fabric Interconnect, not directly to a traditional Ethernet network. Blade servers in a chassis are typically hot-swappable, unlike the components of a rack-mount server. Therefore, blade server configurations are less likely to result in prolonged downtime if hardware fails.
Cisco UCS E-Series servers are typically installed in a blade chassis. However, Cisco UCS E-Series servers have similar capabilities to the standalone C-Series servers and do not require connectivity to a UCS fabric. In a small office environment, Cisco UCS E-Series servers are capable of providing the network connectivity and capabilities of a C-Series server along with the availability of B-Series servers.
Cisco UCS Mini servers are a compact integration of a Cisco UCS 5108 blade chassis, Cisco UCS 6324 Fabric Interconnects, and Cisco UCS Manager. Unlike other Cisco UCS servers, the UCS Mini server requires a special version of Cisco UCS Manager for management. It is possible to connect Cisco UCS C-Series servers to Cisco UCS Mini servers in order to expand their abilities.
Cisco UCS M-Series servers are neither rack servers nor blade servers. M-Series servers are comprised of computing modules that are inserted into a modular chassis. The chassis, not the server, can be installed in a rack. The modular design enables the segregation of computing components from infrastructure components.
