Physical Design of the Advanced Load Balancing for VMware Cloud Foundation

These design decisions are recommendations for the optimum functioning of the NSX Advanced Load Balancer.

Table 1. Design Decisions for Physical Design of ESXi Hosts to support the VMware NSX Advanced Load Balancer

Decision ID	Design Description	Design Justification	Design Implication
AVI-PHY-001	Provide high performance disks (SSD/ Flash) to hosts that run the Controller VMs.	The Controllers need high performance disks to process the analytics pipeline.	None
AVI-PHY-002	Enable AES-NI instructions setting in the BIOS for ESXi hosts.	AES-NI instruction set provides efficiency in SSL performance.	Most modern machines have AES-NI enabled by default, if not enabled by default, you need to reboot ESXi hosts to enable this setting.
AVI-PHY-003	Disable C-State and P-State settings in BiOS on the ESXi hosts. Note: This is an optional design decision.	Provides maximum performance.	This might require a reboot and reconfigure of the BIOS causing an outage for each ESXi host.
