The average value from four measurements at the back of the rack is -26.9dB(A)! Here is an introduction to 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 and at a height of 1 meter. The average value from four measurements taken at the back of the rack was -26.9dB(A). We received feedback stating, "Even under maximum load conditions, the noise level has significantly decreased. With this, we can hold meetings and classes in this room. There are absolutely no issues with the required performance." [Case Overview] ■ Target Equipment: VT64 Server XS2-2TI and others ■ Implemented Rack: S8.0ZR-24U ■ System Support: Visual Technology Co., Ltd. ■ Laboratory Name: Not disclosed *For more details, please refer to the PDF document or feel free to contact us.
