The average value from four measurements at the back of the rack is -26.9dB(A)! Introducing examples of silent rack implementations.
We would like to introduce a case where our silent rack, the 'S8.0ZR-24U', was implemented in the laboratory of Toyota Technological Institute. The noise measurement conditions involved placing the measurement microphone 1 meter away from the target equipment at a height of 1 meter. The average value from four measurements taken at the back of the rack was -26.9 dB(A). "We noticed a significant reduction in noise even under maximum load conditions. With this, we can hold meetings and classes in this room. There are no issues with the required performance," was the feedback we received. 【Case Overview】 ■ Target Equipment: VT64 Server XS2-2TI and others ■ Implemented Rack: S8.0ZR-24U ■ System Support: Visual Technology Co., Ltd. ■ Laboratory Name: Confidential *For more details, please refer to the PDF document or feel free to contact us.
