The new ASICs enable a more flexible set of interfaces for ports carrying 100Mbit to 100 Gbit/second Ethernet and 32 Gbit/s Fibre Channel traffic. The company claims the chips are the first to pack 36 100G ports in a system that fits in a single rack unit. The ASICs also implement flow control tables to monitor all traffic running across leaf and spine switches.
Cisco designed a family of three closely related ASICs for its systems with aggregate bandwidth ranging from 3.6 to 1.6 Terabits/second. Two of the chips, made in TSMC’s 16FF+ process, started shipping in systems in February, a third will ship within two months.
