Hi Marcello, In my experience, your suggested specification should be fine for use in a lab trail, in which you just place occasional calls. However, if you plan to send even low levels of load through the system, I'd recommend using the larger spec with 4GB RAM per node and 2vCPUs. This would require 28vCPUs and 56GB RAM - nearly all of the resources on your planned host. I recommend against over-provisioning resources for virtual telephony applications, as this can lead to unpredictable processing delays, and high latency.
One more suggestion. You are planning on using redundant Project Clearwater nodes in your deployment for resilience. However, you are still vulnerable to hardware failures as your host is a single point of failure. For a fully redundant system, you need at least two hosts, and you will need to set up anti-affinity rules to make sure that each of your pairs of nodes is split between the two hosts. Given both of these points, I suggest adding a second host to your deployment.

Thank you for the answers. So I'd want to add a bit about my intents and get more suggestions from you about Clearwater. I'm an IMS Engineer and, unfortunately, I discovered Clearwater too late :). My idea is to create an environment to test an opensource orchestrator for basic ETSI use cases, scale up/down in/out the Clearwater vIMS VNFs, simple calls and basic IMS services. I'm thinking to implement software OPNFV architecture (Brahmaputra release) for this purpose and my opinion to dimension this TestPlant is to have the following: Resources: · 2 x 8 core CPU > 2.00 Ghz (Intel VT-X o AMD-V Capable) · 64 GB RAM · 2 x 500GB SAS HD (Raid 1/0) NFVI will be created with OpenStack as Iaas infrastructure, KVM as hypervisor and Compute node, ONOS, OVS, OpenDaylight and OpenContrail for Network node, Ceph for Storage node. Then DPDK and ODP as Accelerators. So the following architecture: [cid:[email protected]] Moreover a MANO open software like cloudify (for example) to manage Onboarding, VNFs lifecycle, scale up/down/in/out, multiple VNFMs and VIMs ecc... About number of VMs I think: Virtual Machines: · 7x2 VMs (Sprout, Bono, Homer, Ellis, Bind9, Homestead, Ralf) in a redundant configuration; · 1 VMs for Openstck; · 1 VM for Ceph; · 1 VM for ONOS, OVS, OpenDaylight and OpenContrail · 1 VM for OpenMANO or Cloudify For the moment I'm thinking to get experience only on Openstack cloud, then I'll move to VMWare too. · Do you think these Resources and Virtual Machines are enough for my scope? What do you think ? · Do you see some limitation by Clearwater vIMS node side? I'm sorry if I ask you so many things but your product is very interesting as testing purpose on NFV. I'm very grateful if you could answer to these my doubts. Thank you very much, I'm looking forward to hearing you.

As part of Project Clearwater development, we have tested on OpenStack, VMware, and AWS. We have used KVM for our OpenStack testing as it's the default, but other hypervisors should work. We usually use small VMs. Our chef-created deployments in Amazon EC2 use VMs with 1vCPU, 2GB RAM, and 5GB storage. We have also done some testing on VMware using larger VMs: 2vCPUs, 4GB RAM, and 20GB storage. Project Clearwater scales by adding more nodes to the cluster, not increasing the size of the individual VMs, so these should be a reasonable place to start. Please let us know if you have any more questions.
