The Gigaswitch SCP card has (at last count) 16MB of DRAM for buffering packets (and other stuff) that get forwarded by the crossbar. The FGL cards (FDDI line cards) have 1MB of DRAM. There's a Digital Technical journal article available on-line that describes the Gigaswitch in detail. The URL is http://www.digital.com/info/hpc/sc95/sygiga-dtj.html Buffer management is discussed in the "Design Issues" section: http://www.digital.com/.i/info/hpc/sc95/sygiga-dtj-design.html Module details (like types and quantities of memory) are listed in the (hm) "Module Details" section: http://www.digital.com/.i/info/hpc/sc95/sygiga-dtj-module.html We have a Gigaswitch/FDDI at the Palo Alto interconnect, if you'd like to have a look at one.
