CoolSim helps data center managers address two critical questions: Do you have sufficient cooling capacity for increasing IT loads, and where should you deploy additional equipment? Quickly develop CFD models to simulate normal operations and cooling unit failures, identify your most critical cooling units, and create comprehensive thermal management plans for your data center.
