Expert Statements
Jim Handy, General director of Objective Analysis
“CXL is starting to gain widespread adoption in AI systems since they reap strong benefits from its very high bandwidth and support of large memory sizes”
Jim Handy, General director of Objective Analysis
“In addition, today’s memory shortage and subsequent high prices are driving IT managers to use CXL to re-deploy used DDR4 DIMMs into DDR5 systems for immediate cost savings.”
Jim Handy, General director of Objective Analysis
“In the near future, these same managers will use CXL’s memory pools to reduce stranded memory and drive greater savings, and they will find controllers that offer compression, as this one does, to be even more interesting.”
Will Chu, Executive vice president and general manager, Custom Cloud Solutions at Marvell
“Marvell is the only provider with a complete end-to-end CXL portfolio spanning memory expansion (Structera X), near-memory acceleration (Structera A), and PFMA (Photonic Fabric™ Memory Appliance), pod-scale CXL memory-sharing appliance, giving customers a complete portfolio from direct-attach to disaggregated memory pooling”
Will Chu, Executive vice president and general manager, Custom Cloud Solutions at Marvell
“We are delivering industry-leading CXL controllers, co-developed with leading hyperscalers to address the most demanding AI infrastructure requirements.”
Raghu Nambiar, Corporate vice president, Data Center Ecosystems and Solutions, AMD
“AMD is advancing an open ecosystem that gives enterprises the freedom to build infrastructure around their evolving workloads.”
Raghu Nambiar, Corporate vice president, Data Center Ecosystems and Solutions, AMD
“CXL is an important part of that vision, enabling customers to expand memory capacity and use resources more efficiently as AI and data-intensive applications grow.”
Raghu Nambiar, Corporate vice president, Data Center Ecosystems and Solutions, AMD
“Our collaboration with Marvell builds on the performance and scalability of AMD EPYC processors to help enterprises realize those benefits, bringing greater flexibility and long-term value to their data center investments.”
Eddie Ramirez, Vice president of go-to-market, Cloud AI, Arm
“As AI becomes more agentic, memory and compute need to scale together to meet growing infrastructure demands.”
Eddie Ramirez, Vice president of go-to-market, Cloud AI, Arm
“Marvell’s latest Structera X controllers bring CXL 3.2, memory expansion and compression to the Arm ecosystem, giving hyperscaler customers more options to efficiently support complex AI workloads.”
Jangseok Choi (JS Choi), Vice president of the Memory Product Planning Team at Samsung Electronics
“CXL is reshaping how memory is deployed in data centers, and our work with Marvell ensures customers can confidently deploy Structera with Samsung DDR memory for reliable, high-performance systems”
Jangseok Choi (JS Choi), Vice president of the Memory Product Planning Team at Samsung Electronics
“The move to CXL 3.2 and six memory channels in Structera X 3406/3506 further strengthens the flexibility our joint customers need.”
Uksong Kang, Head of Next Generation Product Planning and Enabling at SK hynix
“Working with Marvell to validate Structera with SK hynix memory supports our shared goal of making memory expansion more accessible and flexible”
Uksong Kang, Head of Next Generation Product Planning and Enabling at SK hynix
“Structera X 3406/3506 gives customers the tools they need to build future-ready, disaggregated architectures with less friction and more choice.”
