Hardware requirements This section provides the hardware requirements for the Cisco UCS C-Series Rack Servers. Child TopicsVMware NSX-T Data Center hardware requirementsThe selection and sizing of the hardware platform for the VMware NSX-T Data Center design considers the VMware system requirements for the various components. Cisco UCS C220 M5 component configuration overviewReview component values for the Cisco UCS C220 M5 based edge node. CPUFor VMware NSX-T Data Center edge workloads, the optimal configuration has enough CPU cores to prevent oversubscription. Having enough CPU cores provides maximum performance to the VMware NSX-T Data Center edge-node VMs that carry the workload on these nodes. The VMware NSX-T Data Center design includes one large and one medium edge node VM on each of the first four physical edge hosts in the edge cluster. MemoryThe Cisco UCS C220 M5 physical edge host uses 6 or 12 16 GB DDR4-2933 RDIMMs. These RDIMMs provide 96 GB or 192 GB of RAM. NICsThe choice of physical network interface cards in a VMware ESXi host is critical for maximizing performance. VMware NSX-T Data Center makes extensive use of protocol offloading to achieve line-rate performance. Cisco VICThe Cisco VIC 1457 connects to FI using the Cisco SingleConnect technology. Connectivity modelThis section provides information on the connectivity model for VMware NSX-T Data Center. Storage requirementsThere are several requirements for the edge cluster. Network requirements for the Cisco UCS physical edge host serversThe network requirements for the Cisco UCS physical edge host servers are described. VMware virtual network for the physical edge hostsFor Cisco UCS C-Series Rack Server physical edge hosts, a single VMware VDS is created for the physical edge cluster. Logical topology of the physical edge hostThe physical edge host logical topology. Parent topic VMware NSX-T Data Center physical edge clusterThe VMware NSX-T Data Center physical edge cluster connects to the physical network. The cluster provides the physical platform for the network services the edge node virtual machines provide. These services include routing, bridging, and other network services. The Cisco UCS C-Series Rack Servers host the physical edge cluster.
