Figure 9. VMware ESXi Uniform Host Topology
The enclave architecture is not restricted to virtualized server platforms. Bare-metal servers persist in many
organizations to address various performance and compliance requirements. To address bare-metal operating
systems within an enclave (Figure 10), the following features were enabled:
●
Cisco UCS fabric failover to provide fabric-based high availability
◦
This feature precludes the use of host-based link aggregation or bonding.
●
Cisco VICs to provide multiple virtual PCIe adapters to the host for further traffic isolation and specialization
◦
Ethernet-based vNICs with specific roles associated with the enclave system, enclave data, and core
services traffic are created:
- vnic-a and vnic-b support data traffic originating from the host. Two vNICs were defined to allow host-
based bonding. One vNIC is required.
- vcore supports core services traffic.
◦
Private VLANs isolate traffic to the virtual machines within an enclave, providing core services such as
DNS, Microsoft Active Directory, DHCP, and Microsoft Windows Updates.
◦
Two virtual HBAs provide multihoming to available block-based storage.
●
Dedicated VLANs per enclave for bare-metal server connections
