Compute layer Cisco UCS third and fourth-generation components provide compute power in the VxBlock System 1000. The following table lists Cisco Nexus and Cisco UCS components: Component Description Cisco UCS 5108 Blade Server Chassis Cisco UCS Manager manages the 6U blade server chassis that houses FIs, FEX, and servers. Cisco UCS B-Series Blade Servers Includes B200 or B480, M4, or M5 servers. Cisco UCS VICs 1340, 1380, 1440, or 1480 provide connectivity Cisco UCS C-Series Rack Servers Includes C220, C240, or C480, M4, or M5 servers. Cisco UCS VICs 1385, 1387, 1455, 1457, 1495, or 1497 provide connectivity. Third-generation Cisco UCS 6332-16UP Fabric Interconnects Provides 6 x 40 Gbps uplink ports Provides 26 x 40 Gbps downlink ports Provides 8, 12, or 16 FC connections Third-generation Cisco UCS 2304XP or 2304V2XP Fabric Extender Provides up to 4 x 40 GbE connections between blade server chassis and FIs Third-generation Cisco Nexus 2348UPQ Fabric Extender Provides 48 x 1 GbE or 10 GbE and unified port host interfaces (SFP+) and up to six QSFP+ uplink interfaces that operate at 10 GbE or 40 GbE Fourth-generation Cisco UCS 6454 Fabric Interconnects Contains 2 Gbps, 4 Gbps, or 6 100 Gbps uplinks Configured with 8 or 16 FC connections per FI Fourth-generation Cisco UCS 64108 Fabric Interconnects Contains four, six, or eight 100 Gbps uplinks Configured with 8 or 16 FC connections per FI Fourth-generation Cisco UCS 2408, 2204XP, or 2208XP Fabric Extender Connects the I/O fabric between the Cisco UCS 6454 Fabric Interconnect and the Cisco UCS 5108 Blade Server Chassis. The Cisco UCS 64108 Fabric Interconnect supports only the Cisco UCS 2408 Fabric Extender. Fourth-generation Cisco Nexus 2232PP Fabric Extender Provides 32 x 10 GbE and FCoE SFP+ server ports and 8 x 10 GbE and FCoE SFP+ uplink ports in a compact, 1U form factor Each FI reserves multiple ports to connect Cisco SAN switches and carry FC traffic between the compute layer and the storage layer. SAN port channels carry FC traffic between the FIs and upstream Cisco MDS switches. The FEX within the blade server chassis connect to FIs over converged networking. By default, servers in the VxBlock 1000 boot VMware vSphere ESXi from local mirrored SD cards. Booting from SAN is optional. Regardless of the number of blade servers in the blade server chassis, the FEX connect northbound to the FIs with: Two or four Cisco UCS third generation 40 GbE connections Four or eight Cisco UCS fourth generation 10 GbE connections The Cisco UCS 2408 Fabric Extender has eight external 25 Gb ports and 32 internal 10 Gb ports. Each FEX connects northbound to the FIs, regardless of the number of blade servers in the blade server chassis. The Cisco UCS 2408 Fabric Extender works with the Cisco UCS 6454 or 64108 Fabric Interconnect at 25 Gbps. Cisco UCS C-Series Rack Servers connect directly to the following ports: Cisco UCS 6332-16UP Fabric Interconnects Cisco UCS 6454 Fabric Interconnects Cisco UCS 64108 Fabric Interconnects Use a pair of Cisco Nexus 2000 Series Fabric Extenders to increase the scale for Cisco UCS C-Series Rack Servers on Cisco UCS 6332-16UP Fabric Interconnects. The Cisco UCS 6454 Fabric Interconnects can use a pair of Cisco Nexus 2232PP Fabric Extenders to increase the scale of Cisco UCS C-Series Rack Servers. These connections carry IP and FC traffic. The Cisco UCS 64108 Fabric Interconnects do not have a supported FEX for rack mount. NOTE: FEX connectivity is supported only with Cisco UCS third-generation fabric interconnects. VxBlock System builds do not support Cisco UCS C-Series Rack Servers that are FEX connected. Child TopicsCisco UCS fabric interconnectsEach VxBlock System 1000 contains at least two Cisco UCS third or fourth-generation FIs to form a high availability cluster. Cisco UCS serversCisco UCS third and fourth-generation servers combine compute, network, and storage access and virtualization resources into a single Converged System. Compute server connectivityCisco UCS B-Series Blade Servers and Cisco UCS C-Series Rack Servers contain at least one physical Cisco UCS VIC for server connectivity. Cisco UCS B-Series Blade Server connectivityCisco UCS B-Series Blade Servers contain half-width or full-width blades with third or fourth-generation Cisco UCS VICs on M4 and M5 servers. Cisco UCS C-Series Rack Server direct connect modeCisco UCS C-Series Rack Servers can connect directly to the FIs without the use of FEX with direct connect mode. Third-generation Cisco UCS C-Series Rack Server FEX connect modeThe third-generation Cisco Nexus 2348UPQ Fabric Extender allows for additional Cisco UCS C-Series Rack Servers. Fourth-generation Cisco UCS C-Series Rack Server FEX connect modeThe fourth-generation Cisco Nexus 2232PP Fabric Extender allows additional Cisco UCS C-Series Rack Servers. Cisco UCS mixed server configurationCisco UCS has a unique architecture that integrates compute, data network, and storage network access into a common set of components under a single management interface. Cisco Trusted Platform ModuleThe Cisco Trusted Platform Module (TPM) is a computer chip that securely stores measurements, passwords, certificates, or encryption keys that are used to authenticate the Converged System. The Cisco TPM provides authentication and attestation services to enable safer computing in all environments. Disjoint Layer 2 configurationIn a Disjoint Layer 2 configuration, traffic is split between two or more different networks at the FI to support two or more discrete Ethernet clouds. Bare metal support policySince many applications cannot be virtualized, Converged Systems support bare metal deployments, such as nonvirtualized operating systems and applications.
