Join the morning workshop session with Shao Yen – Modeling Immersion Cooling Compatible with OCP Profile

In this workshop, we will present the design and implementation of Wiwynn rack-scale 2-phase immersion cooling management solution. First, we will examine the data schema which defines logical and physical objects of a tank conforms to applicable OCP Profiles. Then we will explain the additional attributes and actions with examples of the adopted chassis types needed for managing a tank. At a quick glance, a tank looks like a super huge enclosure with a bunch of semi-enclosed sleds. However, some intermediate layers in the object hierarchy are needed to signify …

Wiwynn Latest GPU server, find out from: Gregary Liu – Apply OCP Design Principles to Enhance 19 inch Power-Consuming GPU server

For high power consumption systems such as GPU server, the thermal solution is a big challenge. The breakthrough design of isolated cooling air channels is adopted in server board, GPU subsystem, and power supply units of Wiwynn SV500G3. The architecture sets the deep learning performance benefits free from thermal barriers under eight high power computing accelerators. Cooling efficiency is optimized with well managed air flow and hence achieved excellent CFM per wattage ratio. SV500G3 is also able to operate at higher ambient temperature for better PUE. The server board leverages …

Curious about this? Join us: Sam Yang – 48V 2-stage System Efficiency Optimization by using STC Converter with Dynamic Converting Ratio

Google’s proprietary STC employs LC resonant tank to realize soft charging and soft switching. This technology enables high efficiency high density 48V bus as the first stage conversion in a two stage step down system. Two stage combined efficiency varies in various load conditions. High STC converting ratio provides lower input voltage of second stage which leads to less switching loss in 2nd stage VRs. Lower converting ratio gives less current stress of 1st STC converter in high output power range. As a result, high converting ratio is beneficial in …

Don’t miss Anston Chang co-speaking Microsoft Mark A Shaw : – Learning of Designing Project Olympus JBOF with EDSFF SSD

In the presentation, Wiwynn will share the lessons learned in developing Project Olympus FX-16 system which is equipped up to 16 pieces 1U Long with 18mm thick EDSFF NVMe SSDs (SFF-TA-1007). Considering the high density and serviceability requirements, lots of trade-offs have to be made during the design process, such as SSD form factor definition, blind mating, balance of airflow impedance & thermal efficiency.

To meet the upcoming high power density demand with high energy saving, Wiwynn developed an immersion cooling tank solution with 48V DC power delivery. One hundred OCP Tioga Pass server boards are immersed in a tank with 1.2m x 1.2m footprint. Two-phase immersion cooling technology is employed due to the high power density capacity and low Power Usage Efficiency (PUE) with warm water cooling. For easy service and high density design, each two boards are face-to-face compacted in a cartridge with one-hand released handle which is installed in the tank …
