Even then, PCIe 6.0, which tops out at 800 Gbps on a standard x16 interface, will limit NIC port speeds for the foreseeable future. ®.
Key facts
- At the heart of the switches lives Broadcom's 102.4 Tbps Tomahawk 6 ASIC, which they looked at in detail late last spring
- The GPU giant's latest generation of ConnectX-9 superNICs, launching alongside its Vera Rubin rack systems later this year, boast 1.6 Tbps of connectivity
- Even then, PCIe 6.0, which tops out at 800 Gbps on a standard x16 interface, will limit NIC port speeds for the foreseeable future. ®
- Each of Celestica's 64 OSFP224 ports is made up of eight 200 Gbps, links which are aggregated into a single port
Summary
If you thought 800 Gbps Ethernet was fast, wait. The networking vendor this week began taking orders for its DS6000 family of switches, which are aimed primarily at high-performance computing applications like AI training and inference. The switches will be offered in both a 19-inch 3U air-cooled chassis and an OCP-compliant 21-inch design that uses a combination of air and liquid cooling. At the heart of the switches lives Broadcom's 102.4 Tbps Tomahawk 6 ASIC, which they looked at in detail late last spring. Each of Celestica's 64 OSFP224 ports is made up of eight 200 Gbps, links which are aggregated into a single port.
