Cisco introduces the N9348C8D-H2, a 1RU leaf switch with 48 100G SFP-DD ports and eight 400G QSFP-DD uplinks.
Cisco announced the N9348C8D-H2, a fixed 1RU data center leaf switch aimed at adding dense 100G capacity as spine links move to 400G or 800G.
It has 48 SFP-DD ports supporting 10G to 100G and eight QSFP-DD uplinks supporting 40G to 400G.
Built on the Cisco Cloud Scale LS12800 H2 12.8T ASIC, it delivers up to 8 Tbps of forwarding capacity, up to 2 million routes and an 80 MB shared packet buffer.
Ports support breakouts to 50G and 100G endpoints, and the switch can run Cisco NX-OS or ACI on the same hardware as part of the Cisco Nexus One architecture.
