We would like to introduce a case where our silent rack, the 'dBP07V(ZR)-7048grtr', was installed in the laboratory of the College of Information Science and Engineering at Ritsumeikan University. The target equipment is the "SUPER MICRO 7049GP-TRT". "We started using it right away, and it has become so quiet that it makes us laugh; we are using it comfortably. Thank you very much for this wonderful product," we received in an email. In the email consenting to the publication of the comment, it was also mentioned, "It is genuinely quiet." [Case Overview] ■ Target Equipment: SUPER MICRO 7049GP-TRT ■ Installed Product: dBP07V(ZR)-7048grtr (can be reused for 7049GP-TRT) ■ Installation Location: Ritsumeikan University, College of Information Science and Engineering ■ Laboratory Name: Not disclosed *For more details, please refer to the PDF document or feel free to contact us.

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.

The "ZITS Heat Diffusion System" is an air-cooled management solution that offers numerous advantages, risk avoidance, and an exceptionally high cost-effectiveness through the installation of a simple air cooling device. By diffusing the heat generated in the server room into the adjacent large business area, it distributes the load across the entire area’s air conditioning system. Machine cooling ensures that the room temperature (up to 28°C) from the return flow path is always maintained, smartly avoiding localized heat buildup in the server room. Additionally, we provide on-site diagnostics for heat buildup around server racks and throughout the room. We conduct a local survey to identify issues and their solutions, along with predictions of the results. There are no costs involved. Please feel free to consult us. 【Features】 ■ Custom design and on-site installation tailored to various conditions ■ Solutions for temperature issues in the server room ■ No need for additional air conditioning units ■ Noise is contained with no sound leakage *For more details, please refer to the PDF document or feel free to contact us.
