What happened
SK hynix took part in OCP Global Summit 2026, held from the 12th to the 15th in San Jose, California, and demonstrated next-generation memory solutions at the system level, including a proposed memory-centric server architecture based on CXL pooled memory.S1
The System Demo section presented three solutions: CMM-DDR5, MARS, and CMM-Ax. CMM-DDR5 is a CXL Memory Module that lets multiple servers share a memory pool. SK hynix unveiled its second-generation product with 256GB capacity, based on CXL 3.2, more than doubling bandwidth to 80GB/s versus the prior generation and improving energy efficiency by about 30%.S1
MARS (Memory Centric AI Rack System) integrates partner solutions into a single rack with memory at its core, and three demos were shown. With Arcee, Liqid, and Marvell, an AI agent serving demo proved that transferring or reusing a KV cache on CXL pooled memory significantly improves system performance versus network-based methods. With AMD, Penguin, Xcena, and Arcee, a demo confirmed that a CXL hybrid memory rack can store large-scale KV caches on SSD while prefetching needed caches into DRAM. A demo with Pickle showed pooled-memory streaming reducing response latency in a personal AI agent service.S1
CMM-Ax, which combines computation with memory, was demonstrated through an Efficient Long Context LLM Serving system; the underlying research was published at MICRO 2026.S1 The Memory Section displayed eSSDs (PS1010 U.2, PS1110 E3.S, PS1101 E3.S, PEB210 E1.S, PEB210 M.2 2280 with DLC support) and server DRAM including a 256GB 3DS RDIMM, 128GB DDR5 MRDIMM, and 192GB SOCAMM2. Visitors could also mount HBM4 and SOCAMM2 onto an NVIDIA Vera Rubin model, and HBM4E, HBM4, and HBM3 products were exhibited alongside an HBF (High Bandwidth Flash) structure model.S1

Background timeline
- - SK hynix developed the world's first HBM, according to the booth graphic described by the source.S1
- September 2025 - SK hynix signed a business agreement with NAVER Cloud to resolve bottlenecks in cloud AI services using CXL-based memory solutions; the source dates this to September of the year before the 2026 summit.S1
- - OCP Global Summit 2026 held in San Jose, California, where SK hynix presented MARS, CMM-DDR5, and CMM-Ax.S1
XAIPART take
Technical impact
The demos shift CXL memory pooling from datasheet claims to validated rack-level operation, which matters for KV-cache-heavy agentic AI serving. CMM-DDR5 doubling bandwidth to 80GB/s while adding a pooling function makes it a plausible substitute for some node-local DRAM expansion. CMM-Ax points toward in-memory compute for long-context inference, but no throughput figures were disclosed.
Market impact
Procurement teams should expect CXL 3.2 modules and memory-centric rack designs to enter hyperscaler qualification cycles within the next several quarters, since SK hynix has already validated PoC-level results with NAVER Cloud. The breadth of partner names (AMD, Marvell, NVIDIA, Liqid) suggests an emerging multi-vendor ecosystem, but no pricing or volume commitments were disclosed, so near-term purchasing should stay on standard DDR5 RDIMM and eSSD lines.
Action
Design-in teams planning 2027 AI servers should add CXL 3.2 pooled-memory slots to their platform RFPs and evaluate KV-cache tiering against hybrid DRAM-plus-SSD racks. XAIPART recommends requesting SK hynix sample availability and partner interoperability lists through distributor channels now, before volume allocation tightens.
XAIPART Forecast
XAIPART expects SK hynix's second-generation 256GB CMM-DDR5, based on CXL 3.2, to appear in at least one hyperscaler's published server reference design by Q3 2027; if no hyperscaler or OEM platform discloses CXL 3.2 pooled-memory support built on SK hynix CMM-DDR5 by 2027-09-30, this forecast is wrong.
