AI data centres need growing amounts of memory, but buying new modules can add considerable costs to infrastructure projects. Penguin Solutions is addressing this challenge with the SMART CXL-8F2W-D4, a memory expansion card that allows businesses to repurpose compatible DDR4 memory from older servers for newer AI infrastructure.
The card supports up to eight DDR4 RDIMMs and connects them to compatible servers as additional memory capacity. It features a Marvell StructeraX CXL controller and is intended for workloads that need large amounts of memory, such as AI inference and in-memory databases.
Penguin Solutions introduced the SMART CXL-8F2W-D4 on November 12, 2026. The company sees DDR4 as an alternative to newer DDR5 memory for organisations looking to expand AI infrastructure while getting more value from their existing hardware.
The need for additional memory is growing as AI workloads expand. According to TechInsights figures cited by Penguin Solutions, AI data centres account for 34% of DRAM demand in 2026. This figure is expected to climb to nearly 50% by 2029.
Such growth is putting pressure on memory supplies and data centre budgets. Businesses upgrading older servers or building new facilities may need to spend more on memory to meet their capacity requirements. The CXL-8F2W-D4 offers another option by allowing compatible DDR4 modules to serve as additional memory in newer server platforms.
Penguin Solutions has introduced a DDR4 recovery and sourcing programme to help customers obtain suitable memory. Businesses can recover compatible modules from previous-generation servers during technology refresh cycles. They can further source DDR4 memory through resellers when they need additional modules.
After recovery or sourcing, the DDR4 modules can be installed in the SMART CXL-8F2W-D4 card and made available to compatible servers. This approach gives businesses a way to extend the useful life of older memory rather than replacing every module during a hardware upgrade.
Memory condition and reliability are important when older components move into production environments. Penguin Solutions addresses this through its Zefr ultra-high-reliability memory screening process, which checks customer-owned DDR4 modules before installation.
The process covers inspection, testing, and qualification. Penguin Solutions further tests each populated CXL-8F2W-D4 card in a compatible host before shipment. The company describes its testing as a simulation of demanding real-world conditions to check whether the recovered memory is suitable for production environments.
This validation process is particularly relevant for businesses planning to run memory-intensive workloads. It provides an additional check before reused DDR4 modules enter AI infrastructure, where reliable memory operation is important.
Penguin Solutions expects DDR4 reuse to help organisations reduce the cost of expanding memory capacity, extend the useful life of existing components and get more value from previous hardware investments. The actual savings will depend on the availability, condition and compatibility of the recovered memory.
The SMART CXL-8F2W-D4 is available for qualified customer opportunities on compatible CXL 2.0 platforms. Penguin Solutions has not announced general retail availability or pricing.
