I was comparing the Cisco 7508 that I used to have at a previous job to the GRF 400 I just got. As far as the GSR goes, I haven't seen one in real life. It sounds cool, but I want to see one for myself before I say the thing walks on water. My GRF works great now, and I'm satisfied with it's performance so far, though right now it's still not doing much. > there is an order of magnitude > difference in the aggregate b/w supported between the two correct? 4Mb/s > vs 40Mb/s. >From the Ascend Web Page: Available in two sizes, the GRF 400 holds up to 4 media cards for up to 4 Gb/s bandwidth, while the GRF 1600 supports up to 16 media cards for up to 16 Gb/s of bandwidth. The unique GRF switching architecture is specially designed to handle network growth while providing consistent, high performance, regardless of the dynamics of the network. It has the following cards: Ascend ATM OC-3c IP Forwarding Media Card Ascend FDDI IP Forwarding Media Card Ascend HSSI IP Forwarding Media Card Ascend IP/SONET OC-3c IP Forwarding Media Card Ascend 10/100Base-T IP Forwarding Media Card For more details, check http://www.ascend.com/300.html. >From Cisco's: technology preview of Cisco's new family of gigabit switch routers (GSRs) providing high performance solutions ranging from 5 to 60 Gb/s for Internet and large-scale WAN Intranet backbone applications. Now, I've got a GRF 400 with the ATM OC-3c card, the FDDI card, and the 10/100Base-T card. It works flawlessly. And I can't honestly see how the > Also, not that I know anything about the GRF but I think Cisco > claims that 7500 real-world performance is much better than the GRF400. I've had cisco sales reps claim even more ludicrous things while the support engineer started turning red, so who knows... Comparing GateD to IOS becomes more of a religious preference than anything else. I'm content knowing both, truth be told. > maybe someone can post some performance numbers. > -jjk > Joe Shaw - [email protected] NetAdmin - Insync Internet Services
