The server cannot start up when the switch is turned on. To avoid service data loss, stop running services and power off the server before turning on the switch.

6

·     Off (default)—Normal server startup.

·     On—Clears all passwords from the BIOS at server startup.

If this switch is on, the server will clear all the passwords at each startup. Make sure you turn off the switch before the next server startup if you do not need to clear all the passwords.

KVM is a management method that allows remote users to use their local video display, keyboard, and mouse to monitor and control the server.

N

NVMe VROC module

A module that works with Intel VMD to provide RAID capability for the server to virtualize storage resources of NVMe drives.

R

RAID

Redundant array of independent disks (RAID) is a data storage virtualization technology that combines multiple physical hard drives into a single logical unit to improve storage and security performance.

Redundancy

A mechanism that ensures high availability and business continuity by providing backup modules. In redundancy mode, a backup or standby module takes over when the primary module fails.

S

Security bezel

A locking bezel mounted to the front of a server to prevent unauthorized access to modules such as hard drives.

U

U

A unit of measure defined as 44.45 mm (1.75 in) in IEC 60297-1. It is used as a measurement of the overall height of racks, as well as equipment mounted in the racks.

UniBay drive backplane

A UniBay drive backplane supports both SAS/SATA and 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

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