Support information

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

Used to activate and achieve the RAID capabilities of NVMe drives in conjunction with the VMD technology.

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

The IEC 60297-1 standard specifies the units of vertical height measurement for racks and enclosures in the form of "U" or "RU" (rack unit), , where 1 U or 1 RU is equivalent to 44.45 mm (1.75 in).

UniBay drive backplane

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

UniSystem

UniSystem is a software program developed by H3C for server management. It allows for quick and flexible server configurations and intelligent guidance for users. With FIST, users can even develop their own tools. It is an intelligent and scalable server management tool.

V

VMD

The VMD technology provides hot-swapping capability, drive management, and fault tolerance features for NVMe drives, making them reliable, available, and serviceable.
