Symptoms
Customer might call in asking about ports that are reported open by their port scanner.
Cause
This question comes up due to software port scans.
Resolution
The following tables list the open ports and their use.
Inbound Data Collector Ports
The Data Collector accepts connections on the following ports:
Outbound Data Collector Ports
The Data Collector initiates connections to the following ports:
Client Ports
Storage Manager clients use the following ports:
Inbound Ports
The Storage Manager Client and Unisphere Central do not use any inbound ports.
Outbound Ports
The Storage Manager Client and Unisphere Central initiate connections to the following port:
Server Agent Ports
Inbound Server Agent Port
The Server Agent accepts connections on the following port:
Outbound Server Agent Port
The Server Agent initiates connections to the following port:
Port scanners might identify some additional ports as being open. These are UDP ports in the range of 10000 through 65535, and they are used to make OUTGOING connections. UDP ports are stateless meaning that they do not listen for incoming connections. These outgoing connections are used to connect to a service such as NTP, syslog, or any other service that uses UDP.
Dell Compellent Storage uses these UDP ports in the ephemeral port range to make outgoing connections. These UDP ports by design cannot accept an incoming connection.
There is nothing to block with these ports on the Dell Compellent side because nothing can connect to that port.
Inbound Data Collector Ports

Server Agent Ports
Inbound Server Agent Port
The Server Agent accepts connections on the following port:
| Port | Protocol | Name | Purpose |
| 27355 | TCP | Server Agent Socket Listening Port | Receiving communication from the Data Collector |
Outbound Server Agent Port
