● System erase - Deletes the system and storage-related data on selected components of a system. You can delete
information pertaining to BIOS, Lifecycle Controller logs, iDRAC settings, and storage components on the system. However,
you cannot delete the iDRAC license information.
● Security - Support local key encryption.
● Restoring the system - Back up the system profile, including RAID configuration, and restore the system to a previously
known state. Importing a system license, firmware rollback, and restoring system configuration if there is system board
replacement.
● Easy Restore - Automatically restore hardware configuration and license information after a system board replacement
● SupportAssist Collection - Gathers all hardware and OS logs and inventory information required for technical support.
● Lifecycle Controller logs for troubleshooting.
● Hardware inventory - Provides information about the current and factory system configuration.
Starting Lifecycle Controller
To start Lifecycle Controller, restart the system and press <F10> during POST to select Lifecycle Controller from the list
displayed. When Lifecycle Controller is started for the first time, the Settings wizard is displayed which allows you to configure
the language and network settings.
Processors
The Precision 7920 Rack systems feature the Intel Xeon scalable processor family(Skylake-SP) offers versatility across
diverse workloads. These processors are designed for next-generation data centers running on, software defined infrastructure
supercharged for efficiency, performance, and agile services delivery across cloud-native and traditional applications. The Intel
Xeon scalable processor family support workloads for cloud, high-performance computing, networking, and also storage for data
centers.
Processor features
The new Intel Xeon scalable processor family is the next generation core architecture with improved Instructions per Cycle
(IPC) and other architectural improvements. The Intel Xeon scalable processor family not only adds new features, but also
improves upon many features of the predecessor Intel Xeon processor E5-2600 v4 product family, including:
● Virtual address space of 48 bits and a physical address space of 46 bits.
● Intel Hyper-Threading Technology (Intel® HT Technology) when enabled allow each core to support two threads.
● First Level Cache (FLC) 64 KB total. The FLC is comprised of a 32 KB ICU (Instruction Cache) and 32 KB DCU (Data Cache)
● MB Mid-Level Cache (MLC) per core (non-inclusive with the LLC).
● Intel® Advanced Vector Extensions 512 (Intel® AVX-512) with a single AVX512 fused multiply-add (FMA) execution units.
processors which support Advanced RAS enable a 2nd FMA execution unit.
