연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A computer-implemented method for sequential placement of cooling resources in a data center comprises: defining a weighted, higher-order cooling metric, , representing an overall performance of the cooling resources in the data center; enumerating all possible locations in the data center for placing an additional c cooling resources; and placing the c cooling resources in locations in the data center for which is closest to an optimum value. For a performance metric Mi, the weighted, higher-order cooling performance metric can be defined as M^=∑k=0C-1⁢∑i=1R⁢a⁡(i,k)⁢Mi(k), where R represents a number of racks in the data center, C represents a total number of cooling resources placed in the data center, i represents one of the R racks in the data center, Mi(k) represents a value of metric Mi when k cooling resources are shut down, and a(i,k) is a weighting function for rack i with the k cooling resources shut down. A system performing the method and computer-readable media having stored thereon instructions causing a processor to perform the method are also provided.

1. A computer-implemented method for sequential placement of cooling resources in a data center model, the method comprising: defining a weighted, higher-order cooling metric, , representing an overall performance of the cooling resources in the data center model, being based on a calculation of at least one performance metric M, wherein k cooling resources having greater impact on M than other cooling resources are omitted from the calculation;enumerating all possible locations in the data center model for placing an additional c cooling resources; andplacing the c cooling resources in locations in the data center model for which {circumflex over (M)} is closest to an optimum value. 2. The method of claim 1, further comprising: defining the higher-order cooling metric, , in terms of a cooling index Mi, such that M^=∑k=0C-1⁢∑i=1R⁢a⁡(i,k)⁢Mi(k), where R represents a number of racks in the data center model, C represents a total number of cooling resources placed in the data center model, i represents one of the R racks in the data center model, Mi(k) represents a value of metric Mi when k cooling resources are shut down, and a(i,k) is a weighting function for rack i with the k cooling resources shut down. 3. The computer-implemented method of claim 1, further comprising: repeating enumerating and placing until a desired stopping condition is met by a resulting placement of cooling resources. 4. The computer-implemented method of claim 3, wherein the stopping condition is a desired redundancy level. 5. The computer-implemented method of claim 3, further comprising: testing whether the desired stopping condition is met by a new resulting placement of cooling resources after removing one cooling resource from the resulting placement of cooling resources. 6. The computer-implemented method of claim 5, further comprising: identifying that cooling resource which when removed results in a value of closest to an optimum value; andremoving that cooling resource identified. 7. The computer-implemented method of claim 2, wherein Mi is capture index. 8. A system for sequential placement of cooling resources in a data center layout, comprising: a computer storage system in which is stored a database holding a numerical computer model of the data center layout; anda computer processor executing a sequence of instructions directing: defining a weighted, higher-order cooling metric, , representing an overall performance of the cooling resources in the computer model of the data center layout, being based on a calculation of at least one performance metric M, wherein k cooling resources having greater impact on M than other cooling resources are omitted from the calculation;enumerating all possible locations in the computer model of the data center layout for placing an additional c cooling resources; andplacing the c cooling resources in locations in the computer model of the data center layout for which {circumflex over (M)} is closest to an optimum value. 9. The system of claim 8, wherein defining further comprises: defining the higher-order cooling metric, , in terms of a cooling index Mi, such that M^=∑k=0C-1⁢∑i=1R⁢a⁡(i,k)⁢Mi(k), where R represents a number of racks in the computer model of the data center layout, C represents a total number of cooling resources placed in the computer model of the data center layout, i represents one of the R racks in the computer model of the data center layout, Mi(k) represents a value of metric M, when k cooling resources are shut down, and a(i,k) is a weighting function for rack i with the k cooling resources shut down. 10.
