Were a small ISP, over the past year we've started using GNS3 more and more in lue of using physical gear in our lab to test different scenarios and validate configs. Were also leveraging it more for training. Our current GNS3 server is an old HP server with specs below. We installed ESXI and the GNS3 appliance and basically devoted all the server resources to it. It's been working well but now our labs are getting bigger and have sometimes 3-4 people logged into it at the same time. CPU and Mem are getting maxed out at times and things are slowing to a craw.
I got management to approve getting a replacement server, my question is do I go the same route of applying all resources to a single GNS3 VM for everyone to work in one enviroment or build multiple GNS3 VM's? How many vcpu's and mem can a single GNS3 VM handle? Any recomendations or input appreciated as I haven't been able to find a clear answer on this.
OLD Server:
2 x six core xeon
72GB DDR3 memory
2 X 500GB SAS (Raid 1)
New Server:
2 x twenty-two core xeon
384GB DDR4 Memory
10 x 900gb SAS (Raid 10)
Current GNS3 VM:
22 x vcpu
64GB memory
