Astera Labs showcases 320-lane PCIe 6.0 switch for vendor-agnostic scaling in data centers — up to 80 accelerators can be scaled up using PCIe alone
Astera Labs has introduced its Scorpio X-Series 320 Lane Smart Fabric Switch at Computex 2026. This switch supports up to 80 accelerators and offers significant improvements in bandwidth and connectivity compared to previous models. It is designed for vendor-agnostic scaling in data centers, accommodating various types of accelerators.
- ▪The Scorpio X-Series switch provides 320 PCIe 6.0 lanes and 20 Tbps of switching bandwidth.
- ▪It allows for the connection of up to 80 accelerators using a single switch, compared to 32 for older models.
- ▪The new device reduces switch hops from three to one for clusters with more than 64 accelerators.
