B |
|
BMC |
The BMC complies with the Intelligent Platform Management Interface (IPMI) standard, responsible for collecting, processing, and storing sensor signals, and monitoring the operating status of each component. The BMC provides the hardware status and alarm information about the managed objects for the management module, so that the management module can manage the objects. |
K |
|
KVM |
keyboard, video, and mouse |
Daughter board |
A card connected to the mainboard through the connector, level to the mainboard. It is used on a device which has high requirement for space usage. |
M |
|
Panel |
An external component (including but not limited to ejector levers, indicators, and ports) on the front or rear of the device. It seals the front and rear of the chassis to ensure optimal ventilation and electromagnetic compatibility (EMC). |
P |
|
PCIe |
A computer expansion bus standard based on the existing PCI programming and communication standards and a faster serial communication system. Intel is a major contributor to this standard. PCIe is used only for interconnection between applications. A PCI system can be turned into a PCIe one by modifying the physical layer instead of software. PCIe delivers a faster speed and can replace almost all existing bus standards including AGP and PCI. |
Q |
|
GE |
Gigabit Ethernet, which is an extension and enhancement of traditional shared media Ethernet standards. It is compatible with 10M and 100M Ethernet and complies with IEEE 802.3z. |
R |
|
RAID |
A storage technology that combines multiple drives into a logical unit in several ways called "RAID levels", providing redundancy and delivering higher storage performance than a single disk. |
Hot swap |
A technology used to replace system components without shutting down the system, which improves the reliability and maintainability of a system. |
Redundancy |
The ability of a system to keep functioning normally in the event of a device failure by having a backup device automatically replace the faulty one. |
S |
|
SEL |
A non-volatile area and interfaces used to store system events for later fault diagnosis and system recovery. |
Device |
A special computer that provides various services for clients over a network. |
U |
|
U |
A unit defined in International Electrotechnical Commission (IEC) 60297-1 to measure the height of a cabinet or chassis. 1 U = 44.45 mm |
Y |
|
Ethernet |
A baseband local area network (LAN) architecture developed by Xerox Corporation in cooperation with DEC and Intel. Ethernet uses Carrier Sense Multiple Access/Collision Detection (CSMA/CD) and supports a data transfer rate of 10 Mbps on multiple cables. The Ethernet specification is the basis for the IEEE 802.3 standard. |
