Cross-referenced all 70+ KB files against official Oracle docs. Critical fixes: - ExaCS: storage was flash cache not usable disk (76.8→190.8 TB QR), added X11M, removed X10M - ADB-S: OCPU→ECPU migration, 26ai as default, cross-region RTO 15→10 min - Compute: E5 max 94→126, A2 80→78, added E6/A4/BM shapes, 11 GPU shapes - Storage: Higher Perf IOPS 35K→50K, UHP 450K→300K, File Storage 25K→50K - DBCS: E5.Flex max 94→64, storage 80→150 TB, added 26ai - Networking: FastConnect +400 Gbps, NSG max 120 rules Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

|
subnet:
|
|
what: "Subdivision of VCN, can be regional (spans all ADs)"
|
|
types: ["public", "private"]
|
|
recommendation: "Always use private subnets for databases and app servers"
|
|
security_list:
|
|
what: "Stateful firewall rules at subnet level"
|

what: "Network Security Group — firewall rules at VNIC level"
|
|
max_rules: "120 (ingress + egress combined per NSG)"

|
|
what: "Private access to OCI services (Object Storage, ADB, etc.)"
|
|
recommendation: "Always use for database and storage access — no internet traversal"

|
|
notes: "Partner or co-location model, typical setup takes 2-4 weeks"
|
|
ipsec_vpn:
|
|
what: "Encrypted tunnel over internet"
|
|
bandwidth: "Up to 250 Mbps per tunnel, aggregate with multiple tunnels"
|
|
notes: "Good for dev/test or backup connectivity, not production data transfer"

gotchas:
|
|
- id: NET-001
|
|
issue: "VCN CIDR blocks cannot overlap for peering"
|
|
impact: "Plan CIDR ranges carefully for multi-VCN architectures"
|
|
recommendation: "Use a documented IP addressing scheme before deployment"
|
|
- id: NET-002
|
|
issue: "FastConnect provisioning takes 2-4 weeks with partners"
|
|
impact: "Can delay migration timelines"
|
|
recommendation: "Start FastConnect procurement early, use VPN as interim"
|
|
- id: NET-003
|
|
issue: "Security lists apply to entire subnet, NSGs to specific VNICs"
|
|
impact: "Security lists can be too broad for micro-segmentation"
|
|
recommendation: "Use NSGs as primary, security lists as fallback"
