2 Features
Performance and Scalability
⚫Powered by Intel®Xeon®Scalable Skylake or Cascade Lake processors, the
server provides up to 28 cores, 3.8 GHz frequency, a 38.5 MB L3 cache, and
three 10.4 GT/s UPI links between the processors, which deliver supreme
processing performance.
−It supports four processors with 112 cores and 224 threads to maximize the
concurrent execution of multithreaded applications.
−The layered architecture of the processor cache is optimized. The L2 cache
capacity is increased to process memory data directly, which greatly
improves the memory access performance. Each core can exclusively use 1
MB of L2 cache, reducing the load on L3 cache. A single processor can
share a maximum of 38.5 MB L3 cache.
−Intel Turbo Boost Technology 2.0 allows processor cores to run faster than
the frequency specified in the Thermal Design Power (TDP) configuration if
they are operating below power, current, and temperature specification
limits.
−Intel Hyper-Threading Technology enables each processor core to run up to
two threads, improving parallel computation capability.
−The hardware-assisted Intel® Virtualization Technology (Intel® VT) allows
operating system (OS) vendors to better use hardware to address
virtualization workloads.
−With Intel® Advanced Vector Extensions 512 (AVX-512), applications can
pack 32 double-precision and 64 single-precision floating-point operations
per second in a clock cycle within the 512-bit vectors, as well as eight 64-bit
and sixteen 32-bit integers, with up to two 512-bit fused multiply-add (FMA)
units. Compared with Intel®Advanced Vector Extensions 2.0 (Intel®AVX2),
Intel®AVX-512 doubles the width and number of data registers and the width
of FMA units.
−The Cascade Lake processors support Intel® Deep Learning Boost vector
neural network instructions (VNNI) to improve the performance of deep
learning applications.
⚫The server supports double data rate 4 (DDR4) registered dual in-line memory
modules (RDIMMs) and load-reduced DIMMs (LRDIMMs) with error checking
and correcting (ECC). A server fully configured with forty-eight 2933 MT/s
memory modules (only available with Cascade Lake processors) provides 6144

GB memory space and the maximum theoretical memory bandwidth of 549.9
GB/s.
⚫A server supports a maximum of 24 Intel®OptaneTM DC persistent memory
modules (DCPMMs for short). When the DDR4 memory modules are used
together, the server supports a maximum of 15 TB memory capacity (calculated
based on a maximum of 128 GB capacity per DDR4 memory module and a
maximum of 512 GB capacity per DCPMM).
⚫Flexible drive configurations cater to a variety of business requirements and
ensure high elasticity and scalability of storage resources.
⚫The use of all solid-state drives (SSDs) is supported.An SSD supports up to 100
times more I/O operations per second (IOPS) than a typical hard disk drive (HDD).
The use of all SSDs provides higher I/O performance than the use of all HDDs or
a combination of HDDs and SSDs.
⚫The use of 12 Gbit/s SCSI (SAS) serial connection for internal storage provides
2x data transmission rate than the use of 6 Gbit/s SAS connection, maximizing
the performance of I/O-intensive applications.
⚫With Intel integrated I/O, the Intel®Xeon®Scalable processors integrate the PCIe
3.0 controller to shortens I/O latency and improve overall system performance.
⚫The server supports up to 11 PCIe 3.0 slots.
Availability and Serviceability
⚫Carrier-class components with process expertise ensure high system reliability
and availability.
⚫The server uses hot-swappable SAS/SATA/NVMe drives. It supports RAID 0, 1,
1E, 10, 5, 50, 6, and 60, depending on the RAID controller card used. It also uses
a supercapacitor to protect the RAID cache data against power failures.
⚫The server provides simplified O&M and efficient troubleshooting through the
UID/HLYLED indicators on the front panel, fault diagnosis LED, touch LCD
diagnosis panel, and iBMC WebUI.
⚫The SSDs offer better reliability than HDDs, ensuring continued system
performance.
⚫The iBMC monitors system parameters in real time, triggers alarms, and
performs recovery actions in case of failures, minimizing system downtime.
⚫For more information about the warranty in the Chinese market, see Warranty.
Manageability and Security
⚫The built-in iBMC monitors server operating status and provides remote
management.
⚫A password is required for accessing the BIOS, ensuring system boot and
management security.
⚫The Network Controller Sideband Interface (NC-SI) allows a network port to
serve as a management port and a service port for maximized return on
investment (ROI) for customers. The NC-SI feature is disabled by default and can
be enabled through the iBMC or BIOS.
⚫The integrated Unified Extensible Firmware Interface (UEFI) improves setup,
configuration, and update efficiency and simplifies fault handling.
⚫Lockable server chassis panel ensures security of local data.

⚫Intel Execute Disable Bit (EDB) function prevents certain types of malicious buffer
overflow attacks when working with a supported OS.
⚫Intel Trusted Execution Technology enhances security using hardware-based
defense against malicious software attacks, allowing applications to run
independently.
⚫The trusted platform module (TPM) and trusted cryptography module (TCM)
provide advanced encryption functions, such as digital signatures and remote
authentication.
⚫The following requirements in NIST SP 800-147B are met:
−The BIOS firmware digital signature update mechanism is supported. During
the upgrade, the digital signature is verified to prevent unauthorized BIOS
firmware upgrade.
−The flash security protection mechanism is supported to prevent
unauthorized modification of the flash memory in the OS.
The service port with NC-SI enabled supports the following configuration:
⚫Configuring any LOM port of the server as the service port with NC-SI enabled. Host port 1
is configured by default.
⚫Enabling, disabling, and setting a virtual local area network (VLAN) ID for this port. The
VLAN ID is 0and disabled by default.
⚫Configuring IPv4 addresses (IPv4 address, subnet mask, and gateway) and IPv6 addresses
(IPv6 address, prefix length, and gateway) for this port.
Energy Efficiency
⚫The 80 Plus Platinum power supply units (PSUs) of multiple power ratings
provide 94% power efficiency at 50% load.
⚫Efficient voltage regulator-down (VRD) power supplies for boards minimize the
energy loss from DC/DC power conversion.
⚫Area-based, Proportional-Integral-Derivative (PID) intelligent fan speed
adjustment and intelligent CPU frequency scaling optimize heat dissipation and
reduce overall system power consumption.
⚫The improved thermal design with energy-efficient fans ensures optimal heat
dissipation and reduces system power consumption.
⚫The server is protected with power capping and power control measures.
⚫Staggered spin-up for drives reduces the server boot power consumption.
⚫Intel® Intelligent Power Capability allows a processor to be powered on or off
based on requirements.
⚫Low-voltage Intel®Xeon®Scalable processors consume less energy, ideally
suited for data centers and telecommunications environments constrained by
power and thermal limitations.
⚫SSDs consume 80% less power than HDDs.
