Tokyo, Japan – Mizuho Securities is building a new liquid cooling-ready data centre and deploying HPE Cray XD2000 infrastructure to support growing computational demands across its financial operations.
The Japanese securities firm carries out more than 360 million calculations each day for derivatives pricing, market risk and counterparty credit risk, with the volume increasing annually.
The new infrastructure is intended to provide additional computing capacity as the company expands its global business and develops financial products and services.
Installation of the liquid cooling equipment, network infrastructure and operational validation is scheduled to begin this autumn, with the system expected to enter production in mid-2027.
“HPE systems have long underpinned Mizuho Securities’ financial business, and we are delighted that Mizuho Securities is the first in Japan’s financial sector to select HPE Cray XD2000 featuring direct liquid cooling as the foundation for its next stage of growth,” said Hirokazu Mochizuki, Senior Vice President and Managing Director for HPE Japan.
“As Mizuho Securities advances its global business, we see consistent, sustainable compute performance as vital to supporting increasingly demanding financial simulations. Drawing on more than 50 years of liquid cooling technology and HPC expertise, HPE looks forward to deepening this longstanding relationship and supporting the company as it continues to grow and deliver greater value to its customers,” Mochizuki continued.
Mizuho Securities is constructing a new data centre designed to accommodate direct liquid cooling and future expansion. The HPE Cray XD2000 is a density-optimised, scale-out computing system, with direct liquid cooling designed to remove heat from key components.
According to the companies, the configuration can provide up to 20% greater performance per kilowatt than air-cooled solutions while consuming 15% less power. Mizuho Securities expects the new system to deliver 1.6 times the performance per server node compared with its existing environment.
“Mizuho Financial Group is advancing its Global Corporate and Investment Banking strategy, which integrates commercial banking and investment banking capabilities on a global scale,” said Ken Utsunomiya, Operating Officer, CIO, CPrO, Head of Global IT and Head of Global Operations at Mizuho Securities.
“To execute this strategy and deliver higher-value financial products and services to more customers, strengthening our compute infrastructure by transitioning from air cooling to liquid cooling and ensuring reliable operations is essential to our continued business growth. Through this initiative, we will enhance our ability to address increasingly demanding and complex financial simulation requirements and deliver even greater value to our customers,” Utsonomiya continued.
The initial deployment will include eight server nodes, with Mizuho Securities planning to add servers and racks in stages while evaluating the system in its production environment.
HPE Services will provide monitoring and maintenance support, including visibility into the status of the liquid cooling and power infrastructure, as well as automated alerts for coolant leaks.
The company also plans to assess GPU-accelerated computing as part of its exploration of future private AI infrastructure, using the new system to evaluate the effectiveness of direct liquid cooling for these workloads.
