Base infrastructure configuration

Network connectivity

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

  • Link aggregation that uses port channels and virtual port channels (vPCs) is used throughout, enabling the design for higher bandwidth and high availability:

    • vPC is used between the Cisco FI and Cisco Nexus switches.

    • Each server has virtual network interface cards (vNICs) with redundant connectivity to the Unified Fabric. NIC failover is used between FIs for redundancy.

    • Each server has virtual host bus adapters (vHBAs) with redundant connectivity to the Unified Fabric.

  • The Cisco UCS FI is 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 you configure the infrastructure:

  • Storage port interface groups (ifgroups, vPC)

  • 10Gb link to switch N9K-A

  • 10Gb link to switch N9K-B

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

    • 1Gb link to management switch N9K-A

    • 1Gb link to management switch N9K-B

  • 32Gb 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 that is hosted on the AFF storage cluster

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

Host software

The following software must be installed:

  • ESXi installed on the Cisco UCS blades

  • VMware vCenter installed and configured (with all the hosts registered in vCenter)

  • VSC installed and registered in VMware vCenter

  • NetApp cluster configured
