You can create a vSAN stretched cluster with a witness node. You can then create a vSAN storage policy and enable performance service on the vSAN cluster.

Prerequisites
■

Verify that you are connected to a vCenter Server system.

■

Verify that you have access to at least two virtual machine hosts.

■

Verify that each of the virtual machine hosts has at least one SSD and one HDD.

■

Verify that the virtual machine hosts are in maintenance mode.

■

Verify that you have access to an ESXi host that can be used as a witness host or deploy a witness appliance on any node. Ensure that the witness host or appliance is outside the vSAN cluster.

Procedure
1

Configure a vSAN VMkernel port on each of the two hosts. 

New-VMHostNetworkAdapter -VMHost 'Host-A' -PortGroup 'VMkernel' -VirtualSwitch 'vSwitch0' -VsanTrafficEnabled $true
New-VMHostNetworkAdapter -VMHost 'Host-B' -PortGroup 'VMkernel' -VirtualSwitch 'vSwitch0' -VsanTrafficEnabled $true
2

Create a vSAN enabled cluster with automatic disk claim mode. 

$vsanCluster = New-Cluster -Name 'VsanCluster' -Location (Get-Datacenter) -VsanEnabled -VsanDiskClaimMode 'Automatic'
3

Add the two hosts to the vSAN cluster to create a vSAN datastore. 

Move-VMHost -VMHost 'Host-A' -Destination $vsanCluster
Move-VMHost -VMHost 'Host-B' -Destination $vsanCluster
4

Revert the virtual machine hosts to the Connected state. 

Set-VMHost -VMHost 'Host-A','Host-B' -State 'Connected'
5

Create two fault domains in the vSAN cluster. 

$primaryFd = New-VsanFaultDomain -Name 'Primary' -VMHost 'Host-A'
$secondaryFd = New-VsanFaultDomain -Name 'Secondary' -VMHost 'Host-B'
6

Enable stretched cluster. 

Set-VsanClusterConfiguration -Configuration $vsanCluster -StretchedClusterEnabled $true -PreferredFaultDomain $primaryFd -WitnessHost 'Witness-Virtual-Appliance-IP'
7

Create a storage policy by using any vSAN capability. 

$cap = Get-SpbmCapability -Name vSAN*
$rule = New-SpbmRule $cap[1] $true
$ruleset = New-SpbmRuleSet $rule
$policy = New-SpbmStoragePolicy -Name 'vsan policy' -RuleSet $ruleset -Description 'vSAN-based storage policy'
8

Enable performance service on the vSAN cluster. 

Set-VsanClusterConfiguration -Configuration $vsanCluster -PerformanceServiceEnabled $true –StoragePolicy $policy
