Question
12Up to ten (10) application nodes for application pods/containers
- There are 8 worker nodes for internal ODF
- 10 Storage Nodes ODF Advanced 
- How many nodes will be used for interanl ODF?
- Are Storge nodes will be part of applications nodes?

Out of Scope
- Application Backup: This can be part of a future CSI functionality project.

- Cluster Deployment Automation: This can be part of a future E-2-E OpenShift Cluster

Deployment Automation project.

- Ceph deployment. Ceph design must first be scoped through workshops with the Client, and

Ceph deployed before ODF is configured to use external Ceph.

- Ansible deployment: requirements/ integration must first be defined through conducting

workshops with the Client.

vCPU

One vCPU is equivalent to one physical core when simultaneous multithreading (SMT), or

hyperthreading, is not enabled. When enabled, use the following formula to calculate the

corresponding ratio: (threads per core × cores) × sockets = vCPUs.

The UPI installation is highly customisable and tunable. The infrastructure is not configured

within the installation of OpenShift, and the cluster heavily relies on the proper configuration of the

following services:


  • DHCP
  • DNS
  • Proxy
  • Router
  • NAT
  • Firewall
  • web hosting
  • LDAP (Active Directory or equivalent)
  • TFTP/SFTP server
  • NFS

We need to discuss in more details with client and Red Hat team the existing the alternatives that will could help in moving forward fast with the implemenation.
