Description

COMPACT SUPERCOMPUTER

Technical field

The invention relates to computer technology, namely to medium-performance supercomputers designed to operate in unprepared premises (premises not equipped with uninterruptible power supply, air conditioning, ventilation, fire extinguishing systems) such as administrative buildings, offices, business centers, halls of various premises, etc. P. The invention can be used in the design of new computing systems, to increase the power of existing computing systems and as an independent compact supercomputer.

Prior Art

Currently, there are many different supercomputers that have different configurations of both computing equipment and engineering systems that ensure its operation. Such systems, as a rule, include uninterruptible power supply systems, air conditioning systems, fire extinguishing systems, emergency ventilation systems, etc. During the operation of such supercomputers, the interaction of its systems with each other becomes important, since the functioning of one of the systems can affect both the functioning of another system and the integrity of the most expensive computing equipment. In this regard, the developers of modern supercomputers pay special attention to the interaction of engineering systems, both among themselves and with computing equipment. At present, one of the main criteria for a supercomputer is its compactness, which allows it to be placed in any room without special preparation.

An analogue of a supercomputer of average performance is known from the article “VNIITF Zubr supercomputer: a combination of computing power, compactness and reliability” [the article is published on the Internet, link to the article: http://www.vniitf.ru/supercomputer/1335-zubr1. The supercomputer contains a case that houses the air conditioning section with a controller, a server rack for computing (server) equipment, an uninterruptible power supply system, and an emergency fire extinguishing system. The server rack of this supercomputer is equipped with computing equipment, which, due to the presence of an air conditioning section, an uninterruptible power supply system and an emergency fire extinguishing system, can function in a normal room that does not require special training.

Features coinciding with the essential features of the claimed invention are - a case in which the air conditioning section with a controller, a server rack for computing equipment, an uninterruptible power supply system, an emergency fire extinguishing system are located.

The disadvantages of this supercomputer include the low security of computing equipment, which is due to the lack of protection of computing equipment from malfunctions of air conditioning systems.

An analogue of a supercomputer of average performance from the catalog "Liebert precision air conditioning systems" is known [the catalog is published on the Internet, link to the catalog: htp://old.radiusgroup.ru/files/841/Liebert%202010.pdf, pp. 67-71 ].

The supercomputer contains a case in which an air conditioning section with a controller, a server rack for computing equipment, power distribution units, an uninterruptible power supply system, an emergency fire extinguishing system, an emergency ventilation control system and emergency ventilation equipment are located, while the air conditioning section forms a refrigeration circuit with an external unit. Also, the well-known supercomputer includes a monitoring system, which, unlike the previous analogue, allows you to monitor the possible occurrence of malfunctions in air conditioning systems and uninterruptible power supply. Features coinciding with the essential features of the claimed invention are a case that houses the air conditioning section with a controller, a server rack for computing equipment, power distribution units, an uninterruptible power supply system, an emergency fire extinguishing system, and a monitoring system.

However, the disadvantages of the analogue include the insufficient security of computing equipment, due to the fact that the uninterruptible power supply system does not ensure the operability of the air conditioning system when the external power supply is turned off, and the backup ventilation system, when the external power supply is turned off, supplies uncleaned air from the volume of the data center room. This requires additional purification and cooling of the air in the data center room.

As a prototype, a medium-performance supercomputer was chosen from the catalog "Liebert XDFN cooling with a closed cycle of racks with high heat dissipation" [the catalog is published on the Internet, link to the catalog: http://www.icsgroup.ru/upload/iblock/93a/XD FN%20Russo%20Stampa% 2024-01-06 Layout%20 l.pdf].

The supercomputer contains a case in which an air conditioning section with a controller, a server rack for computing equipment, power distribution units, an uninterruptible power supply system, an emergency fire extinguishing system, an emergency ventilation control system and emergency ventilation equipment are located, while the air conditioning section forms a refrigeration circuit with an external unit.

Features coinciding with the essential features of the claimed invention are - a supercomputer, contains a case that houses an air conditioning section with a controller, a server rack for computing equipment, power distribution units, an uninterruptible power supply system, an emergency fire extinguishing system and a computer equipment control system. This analogue is the closest to the claimed supercomputer and is chosen as a prototype, as it has the largest number of common essential features.

The disadvantage of this supercomputer, like that of the previous analogue, is the insufficient security of computing equipment, due to the fact that the uninterruptible power supply system does not ensure the operability of the air conditioning system when the external power supply is turned off, and the backup ventilation system, when the external power supply is turned off, supplies uncleaned air from the volume of the processing center room data. This requires additional cleaning and cooling of the air in the data center room.

An analysis of well-known supercomputers allows us to conclude that the prior art does not provide for the creation of a supercomputer that provides protection for computing equipment without taking special measures in case of possible malfunctions of air conditioning systems.

Disclosure of invention

The objective of this invention is to create a supercomputer of average performance that provides the necessary degree of protection of computing equipment.

The technical result of the claimed invention is to increase the degree of protection of the computing equipment included in the supercomputer, achieved through the presence of a line for connecting the air conditioning system to the uninterruptible power supply system, as well as the use of air conditioning sections without external blocks, which makes the supercomputer more reliable and compact. Also, the technical result is achieved due to the presence of a signal communication line that provides a signal to collapse the counting field of the computing (server) equipment in the presence of an emergency signal from the controller of the air conditioning section and / or the uninterruptible power supply system.

The specified technical result is achieved by the fact that the supercomputer contains a case in which the air conditioning section is located with controller connected to an uninterruptible power supply system, a server rack for computing equipment, power distribution units, an uninterruptible power supply system, an emergency fire extinguishing system, while the air conditioning section forms a refrigeration circuit with a unit located inside the air conditioning section. According to the invention, the controller of the air conditioning section and the uninterruptible power supply system are provided with their own alarm monitoring relays. Moreover, the accident control relay of the air conditioning section and the accident control relay of the uninterruptible power supply system are combined into a single signal line connected to the computer equipment control system, which is configured to send a signal for the correct shutdown of the computer equipment when the signal line is opened.

The claimed invention contains features that distinguish it from the closest analogues, which allows us to consider it as meeting the condition of patentability "novelty".

New features contained in the distinctive part of the claims are not found in technical solutions of a similar purpose, on the basis of which it can be concluded that the claimed invention complies with the patentability condition "inventive step".

In FIG. 1 shows a structural diagram of a supercomputer front view. In FIG. 2 shows a structural diagram of a supercomputer top view. In FIG. 3 shows the signal circuit of the supercomputer.

Embodiments of the invention

The supercomputer (figure 1) contains a housing 1, which houses at least one air conditioning section 2 and at least one server rack 3. The air conditioning section 2 forms a refrigeration circuit 4 with a condenser 5. The air conditioning section 2 consists of a heat exchanger 6, fan 7, controller 8 with alarm control relay 9. Air conditioning section 2 is made without external blocks, which makes the supercomputer more reliable and compact. In the server rack 3, an uninterruptible power supply system 10 with an accident control relay 11, computing equipment 12, power distribution units 13, an emergency fire extinguishing system 14 are installed. ), which is connected to the computer equipment control system 16 in such a way that when the signal line 15 is opened, the computer equipment control system 16, via the information line 17, gives a command to correctly shut down the computer equipment 12.

The supercomputer works as follows.

From the external electrical network 23, voltage is supplied to the uninterruptible power supply system 10. Further, from the uninterruptible power supply system 10 (figure 1), voltage is supplied to the conditioning section 2, the emergency fire extinguishing system 14, power distribution units 13, from which voltage is supplied to the computing equipment 12. After energizing the emergency fire extinguishing system 14, it constantly evaluates the circulating air for signs of smoke. When voltage is applied, the absence of alarms on the controller 8 of the air conditioning section 2 ensures the closed state of the alarm control relay 9. The absence of alarms in the uninterruptible power supply system 10 also ensures the closed state of the alarm control relay AND (Fig. 3). Thus, the closed state of the two relays 9 and AND ensure the presence of a single signal line 15, which forms a closed circuit connected to the computer equipment control system 16. The presence of a closed circuit in the normal operation mode of the supercomputer ensures that there is no command in the computer equipment control system 16 to properly shut down the computer equipment 12, ensuring the operable state of the supercomputer.

In the case 1, due to the fan 7 of the air conditioning section 2, air is circulated between the air conditioning section 2 and the server rack 3. During circulation, the air heated by the computing equipment 12 and uninterruptible power supplies 10 comes from the server rack 3 through the air channel for heated air 18 to the heat exchanger 6, when passing through it, the air is cooled and through the air channel of the cooled air 19 returns back to the server rack 3. As a result of the supply of cooled air to the server rack 3, the computing equipment 12 and uninterruptible power supplies 10 are cooled. The heat transferred to the heat exchanger 6 as a result of the passage of heated air through it is removed to the environment through a conventional vapor-compression cooling cycle using a condenser 5 blown by external ambient air using a fan 14 and air channels for incoming air 20 and exhaust air 21. The partition 24 serves to preventing the ingress of ambient air 20, blown by the fan 14 of the condenser 5, into the air channel for heated air 18. Thus, a closed space is formed inside the rack 3, bounded by the hermetic case 1, the conditioning section 2 and the rack 3, preventing the flow of external ambient air 20 to the computing equipment 12. The baffle 22 (figure 2) serves to exclude the flow of cooled air from the cooled air duct 19 into the heated air duct 18 bypassing the computing equipment 12, which increases the efficiency of the air conditioning system.

Thus, the technical result is achieved - the presence of a voltage supply line from the uninterruptible power supply system 10 to the conditioning section 2, as well as the use of conditioning sections 2 without external blocks, makes the supercomputer more reliable and compact, which increases the degree of protection of computing equipment. The exclusion of the ingress of ambient air inside the rack 3 to the equipment 12 provides a solution to the problem - increasing the degree of protection of computing equipment.

In the event of an emergency, for example, a decrease in voltage from the external power supply 23, in the uninterruptible power supply system 10, the accident control relay 11 is activated, as a result of which the signal line 15 is opened (Fig. 3). When the signal line 15 is opened, the computer equipment control system 16 generates a signal on the information line 17 for the correct shutdown of the computing equipment 12.

At the same time, the conditioning section 2 and the computing equipment 12 are switched to power supply from the uninterruptible power supply in the uninterruptible power supply system 10. The conditioning section 2 cools the air for a period of time required to shut down the computing process and correctly shut down the computing equipment 12. At this time, the case 1 of the supercomputer remains closed , external, uncleaned air does not enter housing 1.

This improves the reliability of the supercomputer. A technical result is achieved - the presence of a signal communication line 15 provides a signal to fold the counting field of computing equipment in the presence of an emergency signal from the controller of the uninterruptible power supply system.

This makes it possible to solve the problem of reliable protection of computing equipment 12 and its timely and correct shutdown in the event of emergencies in the uninterruptible power supply system 10.

In the event of an emergency, for example, an increase in the temperature of the air leaving the air conditioning section 2, from the air conditioning section 2, the alarm signal is transmitted to the controller 8 (Fig. 1), which opens the alarm control relay 9 (Fig. 3), as a result of which it opens signal line circuit 15. When the signal line 15 is opened, the computer equipment control system 16 generates a signal via the information line 17 for the correct shutdown of the computer equipment 12.

In this case, the conditioning section 2 and the computing equipment 12 are powered from the external power supply network 23. The conditioning section 2 cools the air for a period of time required for the shutdown of the computing process and the correct shutdown of the computing equipment 12. At this time, the supercomputer case 1 remains closed, the external, uncleaned air is not falls into box 1.

Thus, the technical result is fulfilled - the presence of a signal communication line provides a signal to fold the counting field computing equipment in the presence of an alarm from the controller of the conditioning section.

This makes it possible to solve the problem of reliable protection of computing equipment 12 and its timely and correct shutdown in case of emergencies in the air conditioning section.

As a result, computer equipment 12 is reliably protected and its timely and correct shutdown occurs in case of emergency situations in the external power supply system, uninterruptible power supply system 10, air conditioning section 2, and also in case of damage to the signal communication line 15.
