If you’ve got the RAM, I’d stick to 1GB for each VM. You can further tune them down to 512MB each, and they’ll run, but they’ll have little (if any) free memory. Real Arista switches ship with at least 4GB of RAM, but this is a lab after all, so 1GB should be fine. I’ve configured each VM to have one CPU, and 1GB of RAM. The OS in use is Mountain Lion (OSX v10.7.5). I’ve built this lab using my Macbook Pro that has an Intel i7 processor with 16GB of RAM. Until then, you’ll need to read on and build it yourself. Arista has hinted that they may release this into the general population, in which case I may build a Virtual Box appliance to share. Please don’t ask me for a copy, since I will not send you a copy no matter how much you beg. Currently this is only available to existing Arista customers, so see your Arista sales rep to get a copy. Understanding the plight of cash-strapped networking guys the world over, Arista has released a virtual-machine-ready version of their fabulous switch operating system, EOS. As much as I love Arista switches, I’d rather spend my spare cash on guitars my wife and kids. Since Arista is a relative newcomer to the world of Networking, there isn’t a pile of used Arista gear on eBay, so I can’t build a killer lab at home without spending thousands of dollars. When I wrote Arista Warrior, I was lucky enough to have a loaner switch from Arista in my home lab, but sadly they made me give it back. It’s no secret that I love Arista switches.
