Included in this collection because UCSC owns lots of these. The 6610-24 has one packet processor with 4 MB of buffers. Each packet processor has 4 cores, each with 1 MB of buffers. Each core serves six Gig-E ports and two 10 Gb/s ports. There is a 48-port version of this switch that has two packet processors which doubles the total buffer memory.
The debug guide for the 6610 has chip level debug commands for the Prestera switch. Marvell makes a SoC switch with that name, so this tells us a lot about the engine Brocade is using.
Brocade has a nice architectural review. The paper does not explain how multicast packets are processed.
