HPE Aruba Networking CX 6400 12-port 40/100GbE QSFP28 v2 Extended Tables Module

R0X45C is the HPE Aruba Networking CX 6400 12-port 40/100GbE QSFP28 v2 Extended Tables Module, a line card for the modular CX 6400 switch. Its twelve QSFP28 ports take 40GbE or 100GbE optics and cables.

The card installs in the open slots of the 6405 chassis, which has five module slots, and the 6410 chassis, which has ten. It is supported in the base 6405 and 6410 switches as well as the bundled 96-port PoE and 48-port SFP+ configurations. Each line card has a dual-core ARM Cortex A72 CPU at 1.8 GHz and 4 GB of DDR4 memory.

The word Extended in the product title refers to table scale. With R0X45C or its sibling R0X44C in every line card slot, the switch reaches up to 163,840 IPv4 ARP and IPv6 neighbor entries, up to 630,780 IPv4 unicast routes and up to 598,014 IPv6 unicast routes, compared with 49,152 hosts and 61,000 routes for the other line cards. Mixing in any other line card brings the scale back to the standard values. The ACL space on this card is 64,000 IPv4, 16,384 IPv6 and 64,000 MAC entries for ingress and the same for egress, against 20,480, 5,120 and 20,480 for the other cards.

Average 64-byte latency in the series is 1.31 microseconds at 40G and 1.42 microseconds at 100G. Optics and cables for the 100G ports in the 6400 range include the S4B44A 100G SR1.2 transceiver for 100 m of multi-mode fiber, the S3N88A DR (500 m), S3N89A LR (10 km), JL743A ER4L (40 km) and the JL307A 3 m, R0Z25A 1 m and R0Z26A 5 m direct attach cables.
