Das previously held senior leadership roles at NVIDIA, Dell EMC, and Microsoft, and brings deep expertise in enterprise AI, data infrastructure, and cloud computing. He currently serves as an Operating Partner in the Digital Infrastructure group at Stonepeak Partners LP, a position he assumed in April 2025. Das most recently served as Head of Enterprise Computing at NVIDIA, where he led the company’s enterprise AI strategy, launched the NVIDIA AI Enterprise software suite, and worked to make AI more accessible and production-ready for enterprise customers worldwide. Prior to NVIDIA, Das led Dell EMC’s unstructured data storage business, overseeing the scale-out Isilon NAS platform and the scale-out ECS Object platform. Earlier in his career, he spent 14 years at Microsoft where he was an original engineering leader behind the development of Microsoft Azure. Das earned his master’s and doctoral degrees in Computer Science from the University of Wisconsin and his bachelor’s degree in Computer Science and Engineering from the Indian Institute of Technology Bombay. With this appointment, Western Digital's board is comprised of nine directors, eight of whom are external and independent.お知らせ • May 21Western Digital Corporation Advances Next-Generation Trusted Infrastructure With Industry’s First Post-Quantum Cryptography Hard DrivesWestern Digital Corporation announced a significant step in next-generation infrastructure security with the integration of post-quantum cryptography (PQC) into its newest high-capacity Ultrastar UltraSMR hard disk drives. Ultrastar HDDs currently in customer qualification introduce PQC-ready secure boot and firmware protection, establishing a new standard for device trust in the Quantum Era. These drives are currently in qualification with multiple hyperscale customers, reflecting strong early interest in quantum-resilient storage architectures. WD's launch of the first hard drives to implement NIST-approved quantum-resistant algorithms marks a definitive industry transition — from theoretical planning to deployed hardware-level defense. By hardening the root of trust, WD provides a critical safeguard against threats like harvest now, decrypt later (HNDL) and similar attacks. This helps protect the massive data lakes fueling today’s AI innovations against the cryptographic protection-breaking power of tomorrow’s quantum computers. WD is among the first to bring post-quantum cryptography into production storage infrastructure, helping lead the industry’s quantum transition with deployed, standards-aligned, infrastructure-level protection, setting a new baseline for trust in AI-era data systems. AI data systems generate and retain massive, long-lived data sets. Securing that data over decades, not just years, must be a core requirement of modern infrastructure. Long data lifecycles and extended IT service windows widen vulnerabilities. Enterprise storage infrastructure typically remains in service for five years or longer, a timeframe that may overlap with the emergence of cryptographically relevant quantum computers. As decryption capabilities advance, so do the strategies of sophisticated adversaries. HNDL is a present-day threat. Adversaries may collect encrypted or signed data with the intent to decrypt or forge security signatures once quantum capabilities mature. Organizations must begin to prepare for long-term cryptographic resilience today. Firmware-level attacks present a critical risk. Device-level trust is becoming increasingly important as security architectures evolve. A quantum-enabled adversary could potentially forge digital signatures on firmware updates, allowing malicious code to appear authentic and compromising drive security. WD's PQC implementation on the new Ultrastar DC HC6100 UltraSMR is designed to help protect device trust chains from manufacturing through field service. This implementation represents more than a feature enhancement; it reflects a broader shift toward embedding quantum-resilient security directly into the foundation of data infrastructure. The focus is on securing device-level trust, including firmware integrity and key management, rather than data-at-rest encryption. Key elements include: Algorithm selection: ML-DSA-87 (NIST FIPS 204) for high-assurance code signing, with dual-signing using RSA-3072 combining proven and emerging cryptographic standards to ensure strong, resilient security; Infrastructure readiness: PQC-capable public key infrastructure (PKI) and hardware security module (HSM) workflows deployed to support key issuance, rotation, and lifecycle management; Operational continuity: Dual-signing and rollback safeguards designed to support deployment across diverse fleets without disrupting current operations. As quantum security requirements advance, data protection at the infrastructure layer is becoming a baseline requirement for AI-driven enterprises. WD is helping define the next baseline for trust in AI infrastructure, where security is embedded at the foundation of the system, not added as an afterthought. WD expects to expand PQC capabilities across additional enterprise hard drive product lines over time.最新情報をもっと見るRecent updatesお知らせ • Jun 02Western Digital Corporation Demonstrates Storage Innovations and Platforms for Scaling Persistent Ai WorkloadsWestern Digital Corporation announced its presence at Computex 2026 to help the industry understand that AI infrastructure is fundamentally a data system, not just a compute system.
