Host Topology
Standardizing the host topology through Cisco UCS service profiles improves IT efficiency. Figure 9 shows the
uniform deployment of VMware ESXi within the enclave framework.
The main features include:
●
The VMware ESXi host resides in a Cisco converged infrastructure.
●
The VMware ESXi host is part of a larger VMware vSphere High Availability (HA) and Distributed Resource
Scheduler (DRS) cluster
●
Cisco virtual interface cards (VICs) offer multiple virtual PCI Express (PCIe) adapters for the VMware ESXi
host for further traffic isolation and specialization.
◦
Six Ethernet-based virtual network interface cards (vNICs) with specific roles associated with the enclave
system, enclave data, and core services traffic are created:
- vmnic0 and vmnic1 for the Cisco Nexus 1000V system uplink support management, VMware vMotion,
and virtual service control traffic.
- vmnic2 and vmnic3 support data traffic originating from the enclaves.
- vmnic4 and vmnic5 carry core services traffic.
◦
Private VLANs isolate traffic to the virtual machines within an enclave, providing core services such as
Domain Name System (DNS), Microsoft Active Directory, Domain Host Configuration Protocol (DHCP), and
Microsoft Windows updates.
◦
Two virtual host bus adapters (vHBAs) for multihoming to available block-based storage.
●
Four VMkernal ports are created to support the following traffic types:
◦
vmknic0 supports VMware ESXi host management traffic.
◦
vmknic1 supports VMware vMotion traffic.
◦
Two VMknics (vmknic2 and vmknic3) provide the Virtual Extensible LAN (VXLAN) tunnel endpoint
(VTEP) to support traffic with path load balancing through the Cisco UCS fabric.
●
Additional Network File System (NFS) and Small Computer System Interface over IP (iSCSI) VMknics can
be assigned to individual enclaves to support application and segmentation requirements. These VMknics
use the PortChannel dedicated to enclave data.
Note: A maximum of 256 VMkernal NICs are available per VMware ESXi host.
●
Cisco Nexus 1000V is deployed on the VMware ESXi host with the following elements:
◦
PortChannels created for high availability and load balancing
◦
Segmentation of traffic through dedicated vNICs, VLANs, and VXLANs
