Base infrastructure configuration

Network connectivity

The following network connections must be in place before configuring the infrastructure:

  • Link aggregation using port channels and virtual port channels is used throughout, enabling the design for higher bandwidth and HA.

    • Virtual port channel is used between the Cisco FI and Cisco Nexus switches.

    • Each server has vNICs with redundant connectivity to the unified fabric. NIC failover is used between FI for redundancy.

    • Each server has vHBAs with redundant connectivity to the unified fabric.

  • The Cisco UCS FI are configured in end-host mode as recommended, providing dynamic pinning of vNICs to uplink switches.

Storage connectivity

The following storage connections must be in place before configuring the infrastructure:

  • Storage ports ifgroups (vPC)

  • 10G link to switch N9k-A

  • 10G link to switch N9k-B

  • In- band management (active-passive bond):

    • 1G link to management switch N9k-A

    • 1G link to management switch N9k-B

  • 16G FC end-to-end connectivity through Cisco MDS switches. Single initiator zoning configured.

  • FC SAN boot to fully achieve stateless computing. Servers are booted from LUNs in the boot volume hosted on the AFF storage cluster.

  • All Epic workloads are hosted on FC LUNs, which are spread across the storage controller nodes.

Host software

The following software must be installed:

  • ESXi is installed on the Cisco UCS blades.

  • vCenter is installed and configured, with all the hosts registered in vCenter.

  • VSC is installed and registered in vCenter.

  • A NetApp cluster is configured.
