140CHS11000 熱備單元的存在可以優(yōu)化系統(tǒng)的性能

140CHS11000熱備單元的功能主要包括以下幾點：

保持與兩臺自律機間的通訊：熱備單元需要與兩臺自律機進行通訊，以確定哪一臺為主機，哪一臺為備機。

裁決兩臺自律機中哪一個為主機，哪一個為備機：當(dāng)一臺自律機出現(xiàn)故障時，熱備單元需要自動判斷并選擇另一臺自律機作為主機，以保證系統(tǒng)的正常運行。

自動切換主備機：當(dāng)主控單元出現(xiàn)故障時，備用主控單元會自動承擔(dān)主控單元的控制任務(wù)，使整個系統(tǒng)不會發(fā)生停頓。

控制整個終端設(shè)備的運行：熱備處理單元由主控芯片、鎖存器、隨機存儲器、單向隔離的高速模擬開關(guān)、RS-232驅(qū)動芯片、非門電路構(gòu)成，能夠控制整個終端設(shè)備的運行。

實現(xiàn)多任務(wù)控制：多個不同程序可同時運行，實現(xiàn)多任務(wù)控制。

熱備單元在系統(tǒng)中的作用主要體現(xiàn)在以下幾個方面：

提高系統(tǒng)可靠性：熱備單元的存在使得系統(tǒng)在主控單元出現(xiàn)故障時，能夠自動切換到備用主控單元，保證系統(tǒng)的連續(xù)運行，提高了系統(tǒng)的可靠性。

保證數(shù)據(jù)完整性：在系統(tǒng)運行過程中，熱備單元可以實時備份數(shù)據(jù)，并在必要時恢復(fù)數(shù)據(jù)，從而保證了數(shù)據(jù)的完整性。

實現(xiàn)無縫切換：熱備單元可以實現(xiàn)主備機之間的無縫切換，即在主控單元出現(xiàn)故障時，備用主控單元能夠快速接管控制任務(wù)，保證系統(tǒng)的連續(xù)運行。

優(yōu)化系統(tǒng)性能：熱備單元的存在可以優(yōu)化系統(tǒng)的性能，因為備用主控單元可以在主控單元出現(xiàn)故障時迅速接管控制任務(wù)，避免了因主控單元故障導(dǎo)致的系統(tǒng)停頓或延遲。

簡化維護和管理：熱備單元的使用簡化了系統(tǒng)的維護和管理，因為備用主控單元的存在使得系統(tǒng)的維護更加方便快捷。

綜上所述，140CHS11000熱備單元在系統(tǒng)中起著提高可靠性、保證數(shù)據(jù)完整性、實現(xiàn)無縫切換、優(yōu)化系統(tǒng)性能和簡化維護和管理的作用。

140CHS11000 熱備單元的存在可以優(yōu)化系統(tǒng)的性能

The 140CHS11000 hot spare unit provides the following functions:

Communicate with the two SAS: The hot spare unit communicates with the two SAS to determine which one is the host and which is the standby.

Determine which of the two autonomous machines is the host and which is the standby one: When one autonomous machine is faulty, the hot spare unit automatically determines and selects the other autonomous machine as the host to ensure normal system running.

Automatic switchover: When the main control unit fails, the secondary main control unit automatically takes over the control tasks of the main control unit so that the entire system does not stop.

Control the operation of the entire terminal equipment: the hot spare processing unit is composed of the main control chip, the latch, the random access memory, the unidirectional isolated high-speed analog switch, the RS-232 driver chip, and the non-gate circuit, which can control the operation of the entire terminal equipment.

Multi-task control: Multiple different programs can be run at the same time to achieve multi-task control.

The functions of hot spare units in the system are mainly reflected in the following aspects:

Improved system reliability: The hot spare unit enables the system to automatically switch to the standby main control unit when the main control unit fails, ensuring continuous system running and improving system reliability.

Ensure data integrity: During the system running, the hot spare unit can back up data in real time and restore data when necessary to ensure data integrity.

Seamless switchover: The hot spare unit seamlessly switches between the active and standby servers. That is, when the main control unit fails, the standby main control unit quickly takes over control tasks to ensure continuous system running.

Optimize system performance: The presence of a hot spare unit can optimize system performance because the standby MPU can quickly take over control tasks in the event of a MPU failure, avoiding system pauses or delays caused by a MPU failure.

Simplified maintenance and management: The use of the hot spare unit simplifies the maintenance and management of the system, because the existence of the standby master control unit makes the maintenance of the system more convenient and fast.

In summary, the 140CHS11000 hot spare unit plays a role in improving reliability, ensuring data integrity, realizing seamless switching, optimizing system performance, and simplifying maintenance and management.
