Symptoms
Inability to properly use the array either using Command Line, Secure Remote Services, Cloud IQ, or WebUI Services across a Firewall in the infrastructure.
Cause
For proper infrastructure security, it is common to have several Firewalls in the infrastructure. However, some ports are required to be open to allow for proper array usage. Failure to have these ports open results in the inability to access data or allow for proper administration.
See the document "Unity Family Security Configuration Guide ," Sub Section "Communication Security" available on Dell Support Website.
In addition to the referenced document, this article is designed to assist with centrally locating the ports for reference by network admins.
Note: If no Firewall is in use, then ports remain open.
Resolution
For Unity Secure Remote Services connectivity to Dell
These are the ports that are required to be open (outgoing only). No incoming ports are required (from the Internet to the Unity array). These are only required for the Unity Management IP address.
