IT)           Diana / Jose / Kuba 

ATS)       Nikos/ Thomas / Enzo

Status of ATS-IT cloud POC:

Jose status.

• We have added 12 new BareMetal servers and started the stress test and acceptances.
• Last work day of Niklaus he given us an OpenSearch
• IPMI password ATS as to build the workflow.

 

Diana status.

• KBS deployment is on-going and some issues on auth.

 

Enzo we will create VM-Hypervisor to play with them and now we have to test. Planning flavours.

Jose reminded that Hypervisors wasn't never formalized even if comes with the KBS Hypervisor.

Rules for flavour ratios A / B

request delivery regions trough ticket with Cloud team. Overcommit <=10% and 10% spares for live migration.

Procurements of BareMetal should be aligned to the target flavour.

Kuba check from dl1366946 are: 32 physical cores 256 GB of RAM and 1.7 TB of disk 1:8:56

=>   with over-commit of CPU, this can be m4. or without c4.

Next steps: 

Planning BareMetal capacity/hypervisor vs flavour.

Thomas needs to give S3 credential.

KBS single or multi-master?

Live migrations.

Actions:

- Keys for S3 glance

- Adding Octavia by this week

- Add dashboards for opensearch on Grafana, to validate new deliveries

- Add job to see if we are still using IPMI credentials

- Change to anonymous IPMI credentials

- Flavor vs AvZ in architecture

- Proxy for ServiceNow to create tickets for project creation and quota requests
