Appendix A  Specifications and support information

·     8SFF+60LFF

·     The processors with a TDP of 385W are not supported

·     The 6458Q or 8470Q processors are not supported

·     Baidu DPU2.0 smart network adapters are not supported

·     The processors with a TDP of 385W are not supported

·     The 6458Q or 8470Q processors are not supported

·     Rear drives, including PCIe M.2 expander modules are not supported. M.2 drives are not supported at the server rear

·     The supercapacitor is not supported at the server rear

·     OCP network adapters of 25G or higher are not supported

·     Processors with a TDP of more than 185W are not supported

·     Biadu DPU2.0 smart network adapters are not supported

·     The processors with a TDP of 385W are not supported

·     The 6458Q or 8470Q processors are not supported

·     When the server is stacked with other devices, the cooling capability of the server depends on the power density of devices within the cabinet and the cooling capability of the cabinet. The maximum operating temperature of the server might decrease.

·     The maximum operating temperature decreases by 5°C (41°F) in a stacking environment if the maximum operating temperature is declared equal to or greater than 35°C (86°F) for the server.

·     When a fan module fails or a single rotor of a dual-rotor fan module fails, the maximum server operating temperature decreases by 5°C (41°F) and the maximum operating temperature cannot exceed 35°C (86°F). In addition, the performance of processors with a TDP of more than 165 W might decrease.

·     Table 1 does not list temperature requirements on GPUs, because no GPUs are installed on the server.

B

BIOS

The Basic Input Output System (BIOS) is a collection of programs stored on a ROM chip on the server motherboard. It includes critical components such as the Basic Input Output Program, Power-On Self-Test (POST), and system startup programs. The BIOS provides the most fundamental and direct hardware settings and controls for the computer.

C

CPLD

Complex Programmable Logic Device (CPLD) is a type of digital integrated circuit that can construct logic functions according to requirements.

G

GPU

A GPU is one of the most important components of a server. It is used to convert digital signals from the server into analog signals, which are then displayed on a monitor. Additionally, a GPU has image processing capabilities and can assist CPUs in tasks, thereby enhancing the overall operational speed of the server.

H

HDM

Hardware Device Management (HDM) is a control unit used for server management. Through HDM, you can simplify the server configuration process, view server component information, monitor server operation status, and remotely control the server, among other functions.

Hot swapping

Hot swapping capability refers to the ability to remove or install a component in a server while the server is running, without the need to power down the server. This operation does not disrupt the running system and avoids any impact on its operation.

K

KVM device

A Keyboard, Video, Mouse (KVM) device is a physical device that allows you to monitor and manage multiple servers using a single set of keyboard, display, and mouse.

N

Network adapter

A network adapter is a network component that operates at the data link layer. It not only establishes a physical connection and electrical signal matching between the LAN transmission media but also provides functions such as frame transmission and reception, frame encapsulation and decapsulation, medium access control, data encoding and decoding, and data caching.

NVMe VROC module

An NVMe VROC module is used to activate the RAID features of NVMe SSDs. It works in conjunction with the VMD technology to enable NVMe drive array functionality.

R

RAID

Redundant Array of Independent Disks (RAID) is a technology used for combining multiple independent physical drives in different ways to create a disk array, providing higher storage performance and data security than a single drive.

Redundancy

Redundancy means that when a component, such as a fan, fails, the system can automatically utilize a backup component to replace the failed one.

T

Temperature sensor

A temperature sensor is used to detect the temperature at a specific location and transmits temperature information to the server system.

U

U

A unit of measure defined as 44.45 mm (1.75 in) in IEC 60297-1.

UniBay drive backplane

A UniBay drive backplane is a backplane that supports SAS/SATA/NVMe drives.

UniSystem

UniSystem provided by H3C for easy and extensible server management. It can guide users to configure a server quickly with ease and provide an API interface to allow users to develop their own management tools.

V

VMD technology

VMD provides hot swapping, management and fault-tolerance functions for NVMe drives to increase availability, reliability, and serviceability.
