This is very cool [emphasis mine]:
Cisco’s virtual switch smashes throughput records
Exclusive tests show new Catalyst 6500 management blade sets records for recovery times and throughput
Virtualization, long a hot topic for servers, has entered the networking realm. With the introduction of a new management blade for its Catalyst 6500 switches, Cisco can make two switches look like one while dramatically reducing failover times in the process.
In an exclusive Clear Choice test of Cisco’s new Virtual Switching System (VSS), Network World conducted its largest-ever benchmarks to date, using a mammoth test bed with 130 10G Ethernet interfaces.
The results were impressive: VSS not only delivers a 20fold improvement in failover times but also eliminates layer-2 and layer-3 redundancy protocols at the same time.
The performance numbers are even more startling: A VSS-enabled virtual switch moved a record 770 million frames per second in one test, and routed more than 5.6 billion unicast and multicast flows in another. Those numbers are exactly twice what a single physical Catalyst 6509 can do.
