My question was concerning the Cat6500 under a heavy gig load. Not for SLB,
BGP, or what white papers say. Backplanes do not determine the forwarding
abilities of a switch, the Sup does. A "Backplane" is more of a marketing
term used for talking about a switches capacity. I do appreciate your
feedback, and the memory info on the Foundry is greatly appreciated. I
still think of Foundry as a young company. They do have the ability to take
their SLB statistics, and use them as a metric for GSLB (Global Server Load
Balancing) which Cisco can not do without BGP using the Distributed
Director (to my knowledge).
I am about to implement a large gig network and I need to guarantee that the
core can take the load. Cisco has had issues with speed in the past. Cisco
offers more functionality, where other companies focus on raw speed. I
still
plan to use Foundry for GSLB with their ServerIron switch. The ServerIron
is
a VERY impressive product compared to Cisco's Local Director. Thanks for
the
feedback everyone!

FYI, Cisco has now included SLB functions and layer 4 switching in the IOS
for the Cat6500s. Considering the scalability of the 6500s when compared
to the BigIron, I think Cisco has got Foundry beat (at least on paper:
190GB/s for BigIron vs. 256 GB/s for 6500 on the backplane). I've also
heard that the Foundry switches have some rather serious memory allocation
issues that hinder their performance under high-load scenarios.
Oh yeah, and Foundry just can't come close to Cisco's BGP4 implementation,
IMHO.
