HX Stretched Cluster VMware HA configuration

Hi,

Just looked at HX Stretched Cluster Installation Guide and I am a little bit confused about VMware HA configuration. The guide advises to set two isolation addresses to:

das.isolationaddress0 - IP address on Stretch Cluster network on site A (typically the cluster management IP)

das.isolationaddress1 - IP address on Stretch Cluster network on site B (typically the cluster management IP)

 

My doubts:

1) there is only one cluster mgmt IP address

2) assigning ESXi mgmt IP addresses as isolation addresses does not make sense because Master Host in cluster pings Slave Hosts by default, before isolation address is pinged

3) assigning SCVM mgmt IP addresses maybe is more reasonable but the communication still relies on mgmt network

 

From this perspective, replacing default isolation address which is GW is not too beneficial.

 

Any thoughts and comments appreciated.

 

Regards
