● Front storage module PERC with front PERC 10.4

Software RAID

● Operating system RAID/PERC S 150

iDRAC9 with Lifecycle Controller

The embedded systems management solution for Dell servers features hardware and
firmware inventory and alerting, in-depth memory alerting, faster performance, a
dedicated Gb port and many more features.

Wireless Management

The Quick Sync feature is an extension of NFC-based low-bandwidth interface. Quick
Sync 2.0 offers feature parity with the previous versions of the NFC interface with
improved user experience. To extend this Quick Sync feature to wide variety of Mobile
OSs with higher data throughput, the Quick Sync 2 version replaces previous generation
NFC technology with wireless at-the-box system management.

Power supply

● 60 mm / 86 mm dimension is the new PSU form factor
● Platinum Mixed Mode 800 W AC or HVDC
● Platinum Mixed Mode 1400 W AC or HVDC
● Platinum Mixed Mode 2400 W AC or HVDC

Boot Optimized Storage
Subsystem S2 (BOSS S2)

Boot Optimized Storage Subsystem S2 (BOSS S2) is a RAID solution card that is designed
for booting a server's operating system that supports up to:
● 80 mm M.2 SATA Solid-State Devices (SSDs)
● PCIe card which is a Single Gen2 PCIe x 2 host interface
● Dual SATA Gen3 device interfaces

Liquid cooling solution

● The new liquid cooling solution provides efficient method to manage the system
temperature.
● It also provides liquid leak detection mechanism via iDRAC. This technology is managed
by the Liquid Leak Sensor (LLS) mechanism.
● LLS determines leaks as small as 0.02 ml or as large as 0.2 ml.
