Siamak Tavallaei

Senior Principal Engineer, System Architecture
Samsung

Siamak Tavallaei joined the CXL effort as a founding member of the CXL Consortium and co-chair of the Technical Task Force (TTF) in 2019 to develop the CXL 2.0 specification. He has served on the CXL Board of Directors and as the CXL President. In 2016, he joined Open Compute Project (OCP) as a co-lead of Server Project. He is currently the Incubation Committee Representative for the Server Project where he drives open-sourced modular design concepts for integrated hardware/software solutions. He has served as Chief Systems Architect at Google Cloud Platforms where he led the architecture and productization of CXL-enabled solutions. His recent focus has been the optimization of large-scale, mega-datacenters for general-purpose and tightly-connected accelerated machines built on co-designed hardware, software, security, and management. His experiences as Chief Systems Architect at Google Cloud, Senior Principal Architect at Microsoft Azure’s Hardware Architecture team, a Distinguished Technologist at HP, a Principal Member Technical Staff at Compaq, and his contributions to industry collaborations such as CXL, OCP, EISA, PCI, InfiniBand, and PCIe give Siamak a broad understanding of requirements for the Enterprise, Hyperscale, and Edge datacenters for industry-wide initiatives.
