Projeto de implementação completa de nuvem privada OpenStack enterprise com:
- 1 Região (RegionOne)
- 3 Availability Zones (AZ1, AZ2, AZ3)
- 9 Fault Domains (3 por AZ)
- 150 servidores físicos
- 102 TB RAM de compute
- 3.4 PB object storage
- 276 TB block storage NVMe
- 2 tiers de compute: Shared (1:3 overcommit) e Dedicated (1:1)
- GPU Compute: 9 nós com 4x GPU compute-class 80 GB HBM2e cada (36 GPUs, PCI passthrough)
- HSM Key Management: Appliances FIPS 140-2 Level 3, cluster HA com 3 AZs
