Hi @Ibrahim Jamil ,

The ACI Simulator can be set up with as a small topology with one APIC, one spine and two leaves (default) OR with a large topology simulating three APICs, two spines and two leaves.

The dCloud labs use the small topology

At the end of the day, 99.9% of what you'll want to investigate or simulate can be done with one APIC and one spine.  It is only if you want to explore scenarios like an initial setup of 3 APICs or examine the differences in the routing tables when two spines are installed that you'd ever need the large topology (which requires more vCPU and Memory resources - as shown in the Cisco ACI Simulator VM Installation Guide)

Thanks Sir

 

Can y pls advise about to setup ACI Home Lab to test Single-Pod , Multiple-Pod and Multi-Site Topology , the cheapest geat i can get

 

thanks

Hi @Ibrahim Jamil ,

The ACI Simulator will simulate a single ACI pod.  For multi-pod and multi-site, you'll not only need two physical pods, you'll need an additional router to serve as your IPN/ISN.

To practice multi-site, there is a Nexus Dashboard Orchestrator sandbox available on the Cisco DevNet site - and there is also an ACI sim that you can reserve as well as an always-on simulator!


To run your own simulator, you'll need a computer that you can run VMware on - either an ESXi host or VMware workstation or VMware Fusion (won't work on M1 Macintosh).

VMware will have its own requirements for CPU and memory above that required to run the ACI topology. You can find the requirements for VMware Workstation here. Of course, if you are running VMware Workstation or VMware Fusion, the host operating system (Linux, Windows or macOS) will have minimum requirements too.

Personally, I wouldn't try and run ACI simulator on anything less than a multi-threaded PC with a quad core CPU and 64G RAM.  Ideally, something like a Cisco UCS C220 with a Xeon E5 with VMware ESXi installed would be good, but you may not be able to live in the same house as these noisy beasts. 

TBH, I think your best bet is to get onto the DevNet labs! You'll be amazed at the extensive resources available to you there.
