Communications between PowerStore appliances in a cluster are secure. During cluster creation, the primary node of the cluster primary appliance creates a certificate authority (CA) certificate, also known as the cluster CA. The primary appliance passes the cluster CA certificate to the appliances joining the cluster. Each PowerStore appliance in a cluster generates its own unique Internet Protocol Security (IPsec) certificate that is signed by the cluster CA certificate. The sensitive data that PowerStore appliances transmit over their cluster network is protected by IPsec and TLS so that the security and integrity of the data is preserved.
