Detailed description
Intel Xeon processor
E5-2400 and E5-2400 v2
product families
This family of Intel processors has embedded PCIe lanes for improved I/O
performance. See the Processor section for details.
Intel C600 series chipset
The Intel Platform Controller Hub (PCH) chip is implemented on the R520 server.
1600MT/s DDR3 memory
Certain models of the Intel Xeon processor E5-2400 and E5-2400 v2 product
families support 1600MT/s memory. The R520 supports two DIMMs per channel at
1600MT/s with certain models. See the Memory section for details.
Next generation PERC
options
The R520 supports the new PERC controller cards with improved functionality and
faster performance. See the Storage section for details.
PERC S110 software RAID
Solution
This new software RAID solution supports RAID 0, 1, 5 and 10 and supports a
maximum of four hot-plug SATA hard drives or SATA solid-state drives (SSD). See
the Storage section for details.
iDRAC7 with Lifecycle
Controller
The new embedded system management solution for Dell servers features
hardware and firmware inventory and alerting, in-depth memory alerting, faster
performance, a dedicated gigabit port and many more features. See the Dell
OpenManage systems management section for details.
DC power supply
A new 1100W DC power supply option is available for the R520. See the Power,
thermal and acoustics section for details.
Advanced power
management
The R520 supports advanced power monitoring and power capping tools that can
help manage power consumption. See the Power, thermal and acoustics section
for details.
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
section.
Fan fault tolerance
Failure of one fan motor 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.
