Brian, Thanks for the clarification, I was also confused. Resource assessment is important for HEAT, which needs to know #CPUs, memory, etc. of each specific VM.
If we use OOM for Beijing (as I understand), in my opinion the right way to think about it is container-level, rather than VM-level. This means that PTLs should tell how many instances of their component they need (or, put in another way, how many replicas of their containers they need). Resource sizing is then made at cluster level. Depending on how many containers we’ll need to support, the OOM cluster size will be adjusted. Does it make sense?

Folks, Just some clarity based on responses so far. The goal is to estimate the cloud resources we will need for testing and to help guide the testing strategy since likely will not have enough main memory for all the instances we had in Amsterdam with HA and Geo. We are assuming OOM to minimize the footprint so the VM numbers are less relevant. Today in HEAT a full Amsterdam is about 300 GB of main memory (SB01) – DCAE is already clustered If we go with HA/Clustering that becomes “roughly” 600 GB (assuming DCAE is bulk of current memory utilization) for one site and 1.2 TB for two sites but not all components need to scale the same way and there is efficiency with OOM. To the extent you can assess the memory you need in OOM with clustering that would be really helpful.

One suggestion – we might want to separate out the HA/Geo Redundancy columns into 2 sets : one set for local HA only, and a second set for Geo Redundancy. Just by way of example, in the case of SDN-C, we’d need 1 VM for no redundancy, 8 for local HA, and 16 for geo redundancy. I know that our target is geo redundancy, but it might be good to have a view of resources for local HA only as well. That way, if we find we can’t afford the VMs for full geo redundancy, we’ll know the minimal set for local HA as well.

We are working with Catherine, Helen and Brian on estimating the needs in term of Integration Lab resources for Beijing Release. This is important as it will most certainly impact $ budget and thus may require TSC and GB approval. The details have been posted in the wiki at https://wiki.onap.org/display/DW/Integration+labs+need+for+Beijing<https://urldefense.proofpoint.com/v2/url?u=https-3A__wiki.onap.org_display_DW_Integration-2Blabs-2Bneed-2Bfor-2BBeijing&d=DwMFAg&c=LFYZ-o9_HUMeMTSQicvjIg&r=qLcfee4a2vOwYSub0bljcQ&m=CaUG4r_Cugx2h70vsTNpSuic88WvQvOkdEn6HN4L51g&s=PkQYN-ujTSkhOXsPBggjxW5UrwxxkAhonWZo1SoY9rE&e=> and we need every team to fill out the table. Please let my Catherine, Helen, Brian and Brian know if you have any questions. It will be greatly appreciated if the table could be filled out by Monday, Dec 4.
