•  Redundant networking connection
The Lenovo XClarity Controller provides failover capability to a redundant Ethernet connection with the 
applicable application installed. If a problem occurs with the primary Ethernet connection, all Ethernet 
traffic that is associated with the primary connection is automatically switched to the optional redundant 
Ethernet connection. If the applicable device drivers are installed, this switching occurs without data loss 
and without user intervention.
•  Redundant cooling and optional power capabilities
The server supports a maximum of two hot-swap power supplies and six hot-swap fans, which provide 
redundancy for a typical configuration. The redundant cooling by the fans in the server enables continued 
operation if one of the fans fails.
