GNS3 / Dynamips 100+ Routers

http://gns3vault.com After trying about 40 routers I wanted to see what the maximum would be. In this video i'm running 107 routers and I think you could squeeze some more out of it.

CPU: Intel I7 950
Operating system: Ubuntu 10.10 64-bit
Router: C3640-JK9O3S-M
IdlePC value of 0x60503b94

@GNS3Vault Hi am planning to buy a phenom 2 x6 for my gns ccie security lab. How good is it for virtualisation? Could you tell me how much Memory do i need? Thank you

[GNS3Vault]

@TheNullBox A CPU like that will be more than fast enough, no problem to run VMWare or anything else. Each router in GNS3 will use roughly ~180MB I think. Memory is cheap nowadays so I would suggest to get 8 or 12GB...you'll be able to run plenty of routers and a couple of Virtual Machines.

That's g8t,thanks for your response,i did go through the video,would be working to have something like this for my own prep.Thanks again for the response.

@riteshnets your welcome. It's worth having a setup like this. I got rid of all my physical routers (except 1 or 2 for Qos/Voip/Wireless). good luck! Rene

@edur0m3r I would go with the i5 and get more RAM.

Hey so, i need a lap for labbing im trying to decide between a Mac book pro 15' i7 Quad 2.2 GHz

4 GB of 1333 MHz and HD 500 GB a 5400-rpm1 or Mac Book Pro 13 Intel Core i7 Dual-core 2.8 GHz 8 GB SDRAM DDR3 1333 MHz - 2x4 GB Solid State 128 GB... so basically i dont know if it would be worth chaning the quad core for extra ram and solid state disk any advices, i want it to run CCIE labs

So I tried this with my new rig and crashed it. Afterwards I realized you are using a 3600 series which has a way smaller RAM requirement than the 3700. Once my PC hit 100% of physical memory used it stopped responding :/

[GNS3Vault]

@riteshnets An I5 will be more than fast enough. For memory you need roughly 200MB per router. I'm using an I5 for my own CCIE lab. If you want some inspiration look for my "CCIE Lab using GNS3 and Quad NICs for Switches" video.

@GNS3Vault ,thanks a ton for that lightning quick response.Can u also let me know if any i5 (23/24/2500) would help my cause ?

[GNS3Vault]

@riteshnets Your sandy bridge I7 will be awesome for running GNS3. You need about 10 routers max for CCIE and that's a piece of cake. If you have 4GB of RAM your machine will fly.
