After allot of consideration and testing, we have decided on the switches to use for the VPS Cloud (we are now starting to deploy the final hardware), both the front-end Hypervisors and the back-end SAN will be powered by Cisco Catalyst 4948 10GE Enhanced Managed Layer 3 Ethernet Switches.
These bad boys are not cheap, upon their release they commanded a RRP of 30,000$USD, of course, we buying in bulk, so discounts do apply, but cost in this case are well worth the price-tag, we do get redundant dual power supply, wire speed with a 136Gps capacity and a forwarding rate of 72 million packets per second (mpps).. 
Just another example of our commitment to make the VPS Cloud the most stable system for the price you can ever buy into.
