Huawei FusionServer Pro CH242 V5 Compute Node

Technical White Paper Contents

1 Overview

The CH242 V5 is a full-width compute node powered by Intel® Xeon® Scalable

processors. It provides a unique blend of supreme computing power, large

memory, and high exibility and expandability.

The CH242 V5 provides dense computing capability and an ultra-large memory. It

is optimized for virtualization, cloud computing, high-performance computing, and

compute-intensive enterprise applications.

The CH242 V5 compute nodes are installed in an E9000 chassis and are centrally

managed by the management module.

Figure 1-1 CH242 V5

Huawei FusionServer Pro CH242 V5 Compute Node

Technical White Paper 1 Overview

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.

– Intel Turbo Boost Technology 2.0 allows processor cores to run faster

than the frequency specied in the Thermal Design Power (TDP)

conguration if they are operating below power, current, and

temperature specication 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.

– Intel® Advanced Vector Extensions 512 (Intel AVX-512) signicantly

accelerates oating-point performance for computing-intensive

applications.

– The Cascade Lake processors support Intel® Deep Learning Boost vector

neural network instructions (VNNI) to improve the performance of deep

learning applications.

● The CH242 V5 fully congured with 48 LRDIMMs provides supreme speed,

high availability, and a maximum memory capacity of 6 TB.

● The maximum theoretical memory bandwidth is 550 GB/s (64 bit/8 x 2933

MHz x 6 channels x 4), which is 83.3% higher than that of the previous-

generation platform.

● 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 compute node supports 192-lane PCIe 3.0 (8 GT/s per lane) to provide

20% higher I/O bandwidth than the previous 160-lane PCIe.

Huawei FusionServer Pro CH242 V5 Compute Node

Technical White Paper 2 Features

● 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 compute node supports mezzanine cards with a variety of network ports

to meet requirements for exible networking.

● The compute node supports standard PCIe SSD cards.

● The compute node supports LOM that provides two 10GE ports.

Availability and Serviceability

● Memory mirroring and memory module backup prevent system shutdown

caused by uncorrectable memory errors.

● Data is protected using hot-swappable drives and RAID properties.

● The server provides simplied O&M and ecient troubleshooting through the

UID/HLY indicators on the front panel, fault diagnosis LED, and iBMC web

interface.

● The SSDs oer better reliability than HDDs, ensuring continued system

performance.

● The built-in iBMC monitors system parameters in real time, triggers alarms,

and performs recovery actions to minimize the system downtime.

● Huawei provides a three-year warranty for parts replacement and onsite

repair for the servers used in China. Huawei provides a 10-hour-a-day, 7-day-

a-week support program. Service requests will be handled the next business

day. Optional service upgrades are available.

● Huawei provides a three-year warranty for parts replacement and repair for

the servers used outside China. Huawei provides a 9-hour-a-day, 5-day-a-

week support program. Service requests will be handled the next business day.

Huawei delivers the repaired or new parts within 45 calendar days after

receiving the defective parts.

Manageability and Security

● The built-in iBMC monitors server operating status and provides remote

management.

● The integrated Unied Extensible Firmware Interface (UEFI) improves setup,

conguration, and update eciency and simplies fault handling.

● The Advanced Encryption Standard–New Instruction (AES NI) algorithm

allows faster and stronger encryption.

● Intel Execute Disable Bit (EDB) function prevents certain types of malicious

buer overow 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) 2.0 provides advanced encryption

functions, such as digital signatures and remote authentication.

Energy Eciency

● The Intel® Xeon® Scalable processors outperform the previous-generation

processors while tting into the same TDP.

Huawei FusionServer Pro CH242 V5 Compute Node

Technical White Paper 2 Features

● Intel® Intelligent Power Capability allows a processor to be powered on or o

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.

● The 1.2 V DDR4 RDIMMs consume 20% to 30% less power than 1.35 V DDR3

RDIMMs.

● SSDs consume 80% less power than HDDs.

● The hexagonal ventilation holes on the compute node provide higher

ventilation density than round holes, increasing system cooling eciency.

●Ecient voltage regulator-down (VRD) power supplies for boards minimize

the energy loss from DC/DC power conversion.

● The server is protected with power capping and power control measures.
