“Super Micro's ultra-dense server with dual top-bin CPUs and 8 Nvidia HGX GPUs in just 4U with liquid cooling is the ultimate AI server needed in AI factories,” the company said in a statement.
"When installed in a rack, this server quadruples the computing density, allowing organizations to run larger training models with a smaller data center footprint."
“The time to deployment and online are measured in weeks, not months." said Charles Liang, president and CEO of Super Micro.
On Aug. 28 Super Micro Computer tumbled nearly 20% after a delay in filing its annual report. A day earlier the short-selling investment firm Hindenburg Research had taken a stake in SMCI, alleging accounting improprieties. Short sellers bet that a company's stock will decline.
