(Image credit: Tom's Hardware) Astera Labs demonstrated its recently introduced Scorpio X-Series 320 Lane Smart Fabric Switch, which appears to be the industry’s largest open memory-semantic fabric switch, at Computex 2026 in Taipei. The PCIe 6.0 switch with 320 lanes can be used to build large multi-GPU scale-up clusters, large shared KV-cache memory pools, and disaggregate data center infrastructure using custom topologies. (Image credit: Tom's Hardware) The switch provides 320 PCIe 6.0 lanes and 20 Tbps of switching bandwidth, up from 144 lanes and 9 Tbps for previous-generation devices. Astera Labs says the increased number of lanes enables larger scale-up domains, enabling the connection of up to 80 accelerators using a single switch. By contrast, older 144-lane switches support up to 32 accelerators per switch.…
