VCF – vsan – REQD – cfg-004

Add the following setting to the default vSAN storage policy:

Site disaster tolerance = Site mirroring – stretched cluster

Provides the necessary protection for virtual machines in each availability zone, with the ability to recover from an availability zone outage.

You is need might need additional policy if third – party virtual machine are to be host in these cluster because their performance or availability requirement might differ from what the default VMware vsan policy support .

VCF-VSAN-REQD-CFG-005

Configure two fault domains, one for each availability zone. Assign each host to their respective availability zone fault domain.

Fault domains are mapped to availability zones to provide logical host separation and ensure a copy of vSAN data is always available even when an availability zone goes offline.

You is provide must provide additional raw storage when the site mirror – stretch cluster option is select , and fault domain are enable .

VCF – vsan – REQD – CFG-006 Configure an individual vSAN storage policy for each stretched cluster. The vSAN storage policy of a stretched cluster cannot be shared with other clusters. You must configure additional vSAN storage policies.

VCF – vsan – WTN – REQD – CFG-001

Deploy a vSAN witness appliance in a location that is not local to the ESXi hosts in any of the availability zones.

Ensures availability of vSAN witness components in the event of a failure of one of the availability zones.

You must provide a third physically separate location that runs a vSphere environment. You might use a VMware Cloud Foundation instance in a separate physical location .

VCF – vsan – WTN – REQD – CFG-002

Deploy a witness appliance that corresponds to the required cluster capacity.

ensure the witness appliance is sized to support the project workload storage consumption .

The vSphere environment at the witness location must satisfy the resource requirements of the witness appliance.

VCF-VSAN-WTN-REQD-CFG-003

Connect the first VMkernel adapter of the vSAN witness appliance to the management network in the witness site.

Enables connecting the witness appliance to the workload domain vCenter Server.

The management networks in both availability zones must be routed to the management network in the witness site.

VCF-VSAN-WTN-REQD-CFG-004

Allocate a statically assigned IP address and hostname to the management adapter of the vSAN witness appliance.

Simplifies maintenance and tracking, and implements a DNS configuration.

Requires precise IP address management.

VCF-VSAN-WTN-REQD-CFG-005

Configure forward and reverse DNS records for the vSAN witness appliance for the VMware Cloud Foundation instance.

enable connect the vsan witness appliance to the workload domain vCenter Server by FQDN instead of IP address .

You is provide must provide dns record for the vSAN witness appliance .

VCF-VSAN-WTN-REQD-CFG-006

Configure time synchronization by using an internal NTP time for the vSAN witness appliance.

Prevents any failures in the stretched cluster configuration that are caused by time mismatch between the vSAN witness appliance and the ESXi hosts in both availability zones and workload domain vCenter Server.
