• Integrated network support
The server comes with an integrated 1-port Gigabit Ethernet controller with RJ-45 connector, which
supports connection to a 10Mbps/100Mbps/1000 Mbps network.
• Large data-storage capacity and hot-swap capability
With the hot-swap feature, you can add, remove, or replace hard disk drives without turning off the server.
Storage capacity is different depending on server model. See

• 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
The redundant cooling by the fans in the server enables continued operation if one rotor of a fan fails.
• ThinkSystem RAID support
The ThinkSystem RAID adapter provides hardware redundant array of independent disks (RAID) support
to create configurations. The standard RAID adapter provides RAID levels 0 and 1. Optional RAID adapter
with RAID 5, 6, 10, 50, and 60 is available for purchase.
