Hi, yes, typo. I fixed. it. I see, it’s based on my deployment. It used only m1.large flavor, which have 8 vCPU, 16G RAM and 160G storage. So based on what you just told me, here are the new accurate requirements: HEAT * 29 VM * 148 vCPU * 336 GB RAM * 3 TB Storage * 29 floating IP addresses OOM * 17 VM * 54 vCPU * 156 GB RAM * 1020 GB Storage * 15 floating IP addresses DCAE itself * 15 VM * 44 vCPU * 88 GB RAM * 880 GB Storage * 15 floating IP addresses Thanks, Alexis On Jan 4, 2018, at 4:24 PM, JI, LUSHENG (LUSHENG) <l...@research.att.com<mailto:l...@research.att.com>> wrote: Alexis, The 2GB RAM for DCAE is probably a typo? Not sure what VM flavors you use in your deployment. Among the 15 DCAE VMs, 7 (CDAP/Hadoop cluster) need to be m1.large size (4 vCPU, 8G RAM, 80G storage) and the rest are m1.medium size (2 vCPUs, 4G RAM, 40G storage). So the total should be 44 vCPUs, 88G RAM, and 880G disk. The actual usage of disk is much smaller. So if there were a flavor supporting smaller disks (e.g. 20% of current values), the disk usage can be smaller.

The footprint for OOM is slightly smaller, but actually, it’s more than 80% DCAE’s footprint. HEAT * 29 VM * 148 vCPU * 336 GB RAM * 3 TB Storage * 29 floating IP addresses OOM * 17 VM * 123 vCPU * 294 GB RAM * 2300 TB Storage * 15 floating IP addresses DCAE itself * 15 VM * 113 vCPU * 2 GB RAM * 2300 TB Storage * 15 floating IP addresses Hope it helps, Alexis On Jan 4, 2018, at 3:46 PM, Alexis de Talhouët <adetalhoue...@gmail.com<mailto:adetalhoue...@gmail.com>> wrote: Guarav, here are the exact numbers for DCAE requirement. 15 instances 113 vCPU 226 GB RAM 2260 GB disk 15 floating IP On Jan 4, 2018, at 12:22 PM, Alexis de Talhouët <adetalhoue...@gmail.com<mailto:adetalhoue...@gmail.com>> wrote: Gaurav, happy new year to you to!

AdT: - 1 VM for rancher: 2 vCPU - 4 GO RAM - 40 GO disk - 1 VM for ONAP - 8 vCPUS - 64 GO RAM - 100 GO disk - 16 GO swap (I added some swap because in ONAP, most of the app are not always active, most of them are idle, so it's fine to let the host store dirty page in the swap memory.) - 14 VMs for DCAE - 130 vCPUS - 300 GO RAM - 1.5 TO disk (note: this it’s based on memory, I just torn down my setup, and I don’t recall well) b - How many VM if we were to use Rancher based OOM Setup . AdT: As specified above, only one VM for Rancher. c - what is the release I should be using if I were toinstall amsterdam mainteance release . AdT: OOM amsterdam branch. Note: DCAE isn’t yet merged. thanks Gaurav
