zephyr_z9 · x · 2026-11-14
Marvell will showcase its Photonic Fabric memory module at SC26 (Nov 15–20), designed to share memory across racks via optical interconnects without adding more GPUs. Each module supports up to eight DDR5 DIMMs, 72GB of HBM cache, and 7.2Tbps of optical fabric bandwidth, with claimed memory latency below 350ns across racks up to 30 meters apart. The lineup also includes Structera CXL memory expansion, near-memory compute, Teralynx switches, and 1.6T/800G AECs.
