Fresh Air cooling
Dell has tested and validated an integrated data center solution that enables you
to operate at higher temperatures or even chiller-less. See the Power, thermal and
acoustics section for details.
Failsafe hypervisors
The internal dual SD module enables Dell's unique failsafe virtualization
architecture, ensuring uptime by providing failover capability for embedded
hypervisors, such as VMware
®
vSphere
®
ESXi™. See the Supported virtualization
for details.
Fan fault tolerance
Failure of one fan rotor is tolerated with degradation in performance through
active throttling and increased fan speeds. The feature helps reduce downtime by
allowing you to schedule a fan replacement within 360 hours of a fan failure.
