Virtual Cisco 6500

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.

Read the rest here.

  1. LOL we all need to pass the lab ASAP before VSS becomes part of the lab and we have to drop two 6500’s into our home labs :P.

  2. I just e-mailed my Cisco rep this morning, asking their 6500 guy to come in and talk to us about VSS. We’re thinking about maybe upgrading to the Sup720-10GE this year, and perhaps VSS in ’09. Maybe VSS this year, who knows as fast as our company moves sometimes. VSS would clean up our core a lot. Right now we rely on HSRP, cross-stack etherchannels to our 3750 dist layer, EIGRP L3 load-balancing, and spanning-tree roots on even and odd VLANs for rudimentary L2 load-balancing from the dist layer into the core. VSS would clean that all up in a big way and simplify management. We don’t really need the beastly performance that VSS is capable of – we just don’t push that many packets that fast. But it’s always nice to know you COULD if you needed to. 🙂

  3. VSS is really cool stuff, I recently used it for one of our client projects and it’s one of the best equipment I have worked on, failed one 6500 and didn’t loose a single ping to the server/equipment behind it. You can have amazing capacity with both 6500 connecting to each other with 10 Gig cables, is good in core so that one can work on core router without any maintenance notification.
