This topic describes Ethernet management connections. It does not describe the Ethernet iSCSI connections that might be used through a host interface card connection.
Attention: Risk of security breach
– Connect the Ethernet ports on the controller-drive tray to a private network segment behind a firewall. If the Ethernet connection is not protected by a firewall, your storage array might be at risk of being accessed from outside of your network.
The figure shows a controller with Ethernet port 1 and Ethernet port 2.
Note: Ethernet port 2 on each controller is reserved for access by technical support.
Because the controllers support the Auto-MDIX feature, you do not need an Ethernet crossover cable.
