The goal is to figure out how much hardware one need to purchase to run APIC-EM bare-metal. (Would like to run it under ESXi, but the bare-metal comparison can be a little more straightforward.) Will take input on bare-metal or on ESXi..
In particular, what specific CPU and RAM. Also, if you were doing anything that you thought might stress APIC-EM (volumes of API calls. Discovering large networks with large IP address ranges.) would be good to know. Have run it on a 4-core CPU inside lab with no problem (install docs say minimum of 6 cores), but have not stressed APIC-EM to any large degree.
- APIC-EM doc page (with current install requirements): http://www.cisco.com/c/en/us/support/cloud-systems-management/one-enterprise-network-controller/tsd-products-support-series-home.html
- Intel processor page: https://ark.intel.com
Just to get it rolling, so far used the following:
- Generic Rack mount server with:
- Intel E3-1220V2 processor
- 32G RAM
- 500G HDD
- 6 x 1Gbps Ethernet
- bare-metal install
- Mostly doing API calls, QoS, discovery of small (10 device) networks, nothing high-volume
learned about disk throughput may play a role too and hope can get some guide line.
Yep, I see that 200 MBs requirement in the install docs, and it makes me wonder what led to that particular line item. Maybe we'll learn more. Looks like SATA I, II, III, only SATA I is too slow by spec at least. I'm pretty sure the disks on the server I'm using are SATA I (150MBs).
32G is the min ram for 1.x
Disk IO is pretty critical. slow disk mean longer startup times, to the point where it may not actually start. For a small lab you can get away with less than 200MB, but milage will vary and it is not officially supported. if you could get SSD that would really rock.
cpu come into play as well.... slower disk and smaller memory require more cpu. Think we claim 12 for full support.
