AI Leadership Forum launches 4-part CXL memory series

IT Brand Pulse is launching a four-event AI Leadership Forum series on CXL memory deployment, with sessions on Sept. 30 through Jan. 13 featuring Meta, Penguin Solutions and Pacific Northwest National Laboratory. The events aim to show how CXL can expand, pool and reuse memory as AI workloads drive higher capacity needs and rising DRAM costs.

Why it matters: - AI systems are pushing memory demand and memory costs higher, making infrastructure design a bigger budget issue for developers, enterprise IT teams and cloud operators. - CXL is moving from evaluation into production use as companies look for ways to expand memory capacity, improve utilization and reuse existing DDR4 assets. - The series is aimed at helping technical teams respond to rising AI memory needs without replacing all memory with newly purchased hardware.

What happened: - IT Brand Pulse announced a four-part AI Leadership Forum series called “Endless Memory with CXL.” - The virtual events are scheduled for Sept. 30, Oct. 28, Dec. 2 and Jan. 13. - The series will feature speakers from Meta, Penguin Solutions and Pacific Northwest National Laboratory. - Registration is available for each episode through Zoom. - Episode 1 registration: Register for episode 1 - Episode 2 registration: Register for episode 2 - Episode 3 registration: Register for episode 3 - Episode 4 registration: Register for episode 4

The details: - The first episode, “CXL 101 and the New AI Memory Hierarchy,” will explain how CXL works and how memory expansion, pooling, sharing and tiering can complement HBM and server memory. - The second episode, “The Emerging Memory-Centric Data Center,” will focus on AI inference, KV cache, agentic AI, databases, analytics and HPC workloads that need larger memory footprints. - The third episode, “Meta and Penguin Solutions on Reusing DDR4,” will center on DDR4 reuse as servers are retired. - Meta will outline its Vistara technology and deployment, showing CXL-based DDR4 reuse at hyperscale. - Penguin Solutions will present a program, developed with major server OEMs, that lets enterprises reuse existing DDR4 DIMMs with Penguin CXL add-in cards. - Penguin Solutions tests the memory installed on the CXL cards before deployment. - IT Brand Pulse estimates the worldwide enterprise server installed base could contain hundreds of millions, and possibly close to one billion, DDR4 DIMMs. - That estimate is modeled, not an industry-reported installed-base count. - The fourth episode, “PNNL Abaco, CXL Memory Pooling in the Real World,” will cover Pacific Northwest National Laboratory’s Abaco CXL memory pooling system. - Supplier partners in that session include Micron for famfs, Liqid for the system and Scalemem for fabric management. - The series is designed to move from CXL fundamentals to memory expansion, pooling, DDR4 reuse and memory-centric AI architectures. - Viewers will be able to watch the full progression on demand after the live events.

Between the lines: - Frank Berry, founder and analyst at IT Brand Pulse, said memory requirements are rising, DRAM prices are increasing, memory is taking a larger share of infrastructure budgets and billions of dollars of usable DDR4 are being stranded in retired servers. - IT Brand Pulse is framing CXL as a response to several pressure points at once: rising HBM per GPU, higher DRAM prices, larger cloud capex tied to memory and the mismatch between server refresh cycles and longer-lived DDR memory. - The company’s pitch is that CXL can help organizations buy fewer servers, raise utilization and put existing memory to work in new infrastructure. - The 2026 deployments from Meta and PNNL are being presented as evidence that CXL has crossed from emerging technology into production infrastructure.

What's next: - The four live sessions will roll out from Sept. 30 through Jan. 13. - IT Brand Pulse says the event series will walk attendees from technical basics to real deployments and future AI memory architectures. - The forum will continue distributing educational content through LinkedIn, YouTube, SlideShare, newsletters and other digital channels. - The AI Leadership Forum, formerly the AI Infra Forum, says it has hosted 16 forum events since 2022.

The bottom line: - IT Brand Pulse is betting that CXL’s next phase is not theory, but deployment, reuse and memory pooling at AI scale.
