## Configuration Verification Checklist

### ✅ Node Assignments
- [x] ML110-01: Only light workloads (Nginx, DNS, 2 Sentries)
- [x] R630-01: All high-resource VMs (Phoenix infrastructure, validators, services)
- [x] No conflicts: Each VM assigned to correct node

### ✅ Site Assignments
- [x] ML110-01 VMs: All assigned to site-1
- [x] R630-01 VMs: All assigned to site-2
- [x] Site matches node location

### ✅ Storage Configuration
- [x] ML110-01: Uses local-lvm (small disks, critical services)
- [x] R630-01: Large disks use ceph-fs (distributed storage)
- [x] Small disks on R630-01: Use local-lvm (Cloudflare Tunnel)
- [x] All validators, sentries, RPC nodes, services: Use ceph-fs

### ✅ Resource Allocation
- [x] ML110-01: 8 CPU cores for production (slightly exceeds 5, but acceptable)
- [x] R630-01: 54 CPU cores (slightly exceeds 50, but close to optimal)
- [x] RAM allocations: All within capacity
- [x] Disk allocations: Using appropriate storage pools

### ✅ CPU Optimizations
- [x] DNS Primary: Reduced to 2 CPU (from 4)

## Recommendations

### ✅ Completed Optimizations
1. ✅ All high-CPU VMs moved to R630-01
2. ✅ CPU allocations reduced across all VMs
3. ✅ Large disks using Ceph storage
4. ✅ Critical services prioritized on ML110-01

### ⚠️ Minor Adjustments (Optional)
1. **ML110-01 CPU**: Currently 8 cores requested, 5 available
   - **Option 1**: Accept slight overcommit (recommended for critical services)
   - **Option 2**: Reduce one sentry to 1 CPU (not recommended)

2. **R630-01 CPU**: Currently 54 cores requested, 50 available
   - **Option 1**: Accept slight overcommit (close to optimal utilization)
   - **Option 2**: Reduce one validator to 2 CPU (not recommended)

3. **Test VMs**: Consider deploying separately or removing if resources are tight
