ESXi hosts in Teradata management cluster are reserved exclusively for vCenter and Vantage component VMs, such as Viewpoint, Server Management (CMIC), and BYNET relay nodes. Each ESXi host has multiple VMs that are provisioned with sufficient compute, memory, and I\O resource required by the target application. See VantageCore VMware VM Templates.
Each ESXi host is configured as follows:
- Hardware (Node)
- The Management Cluster host BIOS is configured as follows:
- Enable HyperThreading
- Set Power Policy to Balanced
- Storage
- All hosts are configured to run ESXi from local storage – a datastore aligned with RAID-1 vdisk managed by the (internal) H740p PERC. VMs running in the management cluster use datastores provided through a vSAN.
- Networking
- There are six 25GbE NIC ports on each host (vmnic0 – 5) and two 1GbE NIC ports that are allocated across the following virtual distributed switches.
- The 25GbE BYNET dvSwitch is aligned to BYNET physical switches
- BYNET-1 PortGrp/VLAN (MTU: 9000)
- BYNET-2 PortGrp/VLAN (MTU: 9000)
- The 25GbE VM Management dvSwitch is aligned to CLAN and Management physical switches
- CLAN PortGrp/VLAN (MTU: user choice)
- Management PortGrp/VLAN (MTU: 1500)
- vSAN PortGrp/VLAN (MTU: 9000)
- ServiceConnect/Public PortGrp/VLAN (MTU: user choice)
- The 1GbE Chassis Management dvSwitch is aligned to TOR physical switches
- PowerVault-Management PortGrp/VLAN (MTU: 1500)
- The 25GbE BYNET dvSwitch is aligned to BYNET physical switches
