Abstract

In this paper, we present a thermal-aware file assignment technique called TIGER for reducing the cooling cost ofstorage clusters in data centers. We show that peak inlet temperatures of storage nodes depend on not only CPU utilization but alsoI/O activities, which rely on file assignments in a cluster. The TIGER scheme aims to lower peak inlet temperatures of storageclusters by dynamic thermal management through file placements. TIGER makes use of cross-interference coefficients to estimatethe re-circulation of hot air from the outlets to the inlets of data nodes. TIGER first calculates the thresholds of disks in each datanode based on its contribution to heat re-circulation in a data center. TIGER undertakes two steps to achieve high I/O performancewhile reducing cooling cost. First, TIGER assigns groups of files with similar service times to shorten I/O response times. Second,TIGER ensures that load imbalance does not exceed a specified threshold. We evaluate performance of TIGER in terms of bothcooling energy conservation and response time of a storage cluster. Our results confirm that TIGER reduces cooling-powerrequirements for clusters by offering about 10 to 15 percent cooling-energy savings without significantly degrading I/O performance.
