  .SYNOPSIS
    Deploys the Pure Storage OVA for off-array integrations and applications.
  .DESCRIPTION
    Deploys the Pure Storage OVA for off-array integrations and applications.
  .INPUTS
    An authorization key, DHCP info, IP info.
  .OUTPUTS
    Returns the Pure Storage Collector Object.
  .EXAMPLE
    PS C:\ $ds = get-datastore <datastore name>
    PS C:\ $esxi = Get-VMHost <ESXi host name>
    PS C:\ $pg = (Get-VirtualPortGroup -vmhost $esxi)[0]
    PS C:\ $vmname = <desired name of appliance VM>
    PS C:\ $authKey = <collector key from Pure1>
    PS C:\ $mycreds = get-credential
    PS C:\ Deploy-PfaAppliance -vmName $vmName -authorizationKey $authkey -datastore $ds -portGroup $pg -vmHost $esxi -dhcp -ovaPassword $mycreds.Password
    
    Deploys a new OVA with DHCP network configuration. This will also change the default password to the supplied password.
    .EXAMPLE
    PS C:\ $ds = get-datastore <datastore name>
    PS C:\ $esxi = Get-VMHost <ESXi host name>
    PS C:\ $pg = (Get-VirtualPortGroup -vmhost $esxi)[0]
    PS C:\ $vmname = <desired name of appliance VM>
    PS C:\ $authKey = <collector key from Pure1>
    PS C:\ Deploy-PfaAppliance -vmName $vmName -authorizationKey $authkey -datastore $ds -portGroup $pg -vmHost $esxi -dhcp
    
    Deploys a new OVA with DHCP network configuration. This will leave the default password as is. You must change it manually before using the collector.
  .EXAMPLE
    PS C:\ $ds = get-datastore <datastore name>
    PS C:\ $esxi = Get-VMHost <ESXi host name>
    PS C:\ $pg = (Get-VirtualPortGroup -vmhost $esxi)[0]
    PS C:\ $vmname = <desired name of appliance VM>
    PS C:\ $authKey = <collector key from Pure1>
    PS C:\ $mycreds = get-credential
    PS C:\ Deploy-PfaAppliance -vmName $vmName -authorizationKey $authkey -datastore $ds -portGroup $pg -vmHost $esxi -ovaPassword $mycreds.Password -ipaddress <IP> -netmask <netmask> -gateway <gateway> -dnsprimary <DNS> -hostname <FQDN>
    
    Deploys a new OVA with static network configuration. This will also change the default password to the supplied password.
