+Your task list is comprehensive, but there are additional considerations to ensure smooth operation, especially with high-performance hardware and large datasets. Here's a breakdown of what you might be missing:
+
+---
+
+### **1. Hardware & Networking Considerations**  
+- **PCIe Slot Availability**:  
+  Ensure the server has enough PCIe slots for both GPUs (H100/L40) and the 25 Gbit NICs. Dual GPUs (e.g., H100) may require NVLink support, which depends on the motherboard’s PCIe version (e.g., PCIe 4.0 or higher).  
+- **Transceivers**:  
+  If using 25 Gbit SFP+ or QSFP+ ports, confirm the NICs and switches support the required transceivers (e.g., SFP+ for 25 Gbit).  
+- **Power & Cooling**:  
+  Verify the PSU can handle the combined power draw of dual GPUs (e.g., H100s: ~300W each, L40s: ~250W each). Ensure adequate cooling for the server chassis.  
+
+---
+
+### **2. OS & Software Stack**  
+- **Ubuntu Version**:  
+  While Ubuntu 22.04 is stable, **24.04 is recommended** for better support of newer hardware (e.g., H100 GPUs) and security updates.  
+- **Ansible Playbooks**:  
+  Create reusable Ansible playbooks for:  
+  - OS installation (e.g., Ubuntu 24.04).  
+  - GPU driver installation (NVIDIA).  
+  - Network bonding (e.g., `bonding-mode=active-backup`).  
+  - NFS mount configuration.  
+- **CUDA & ROCm**:  
+  Install the latest CUDA toolkit (for NVIDIA GPUs) or ROCm (for AMD GPUs) to ensure compatibility with Boltz.  
+
+---
+
+### **3. Network Configuration**  
+- **Bonding Mode**:  
+  Use `bonding-mode=active-backup` for failover redundancy. Ensure the switches support LACP (Link Aggregation Control Protocol) for bonding.  
+- **Firewall Rules**:  
+  Configure OPNsense to allow traffic between:  
+  - The server and Qumulo storage (NFS).  
+  - The server and other compute nodes (if using Ansible for clustering).  
+- **Qumulo NFS Optimization**:  
+  Use NFS mount options like `noatime`, `async`, or `tcp` for large datasets. Consider setting up a cron job to check NFS mount status.  
+
+---
+
+### **4. GPU & Multi-GPU Support**  
+- **Driver Installation**:  
+  Install the latest NVIDIA drivers (e.g., via `nvidia-driver-535` package) and verify `nvidia-smi` works.  
+- **Multi-GPU Configuration**:  
+  - For **H100 GPUs**: Enable NVLink (if supported) for faster inter-GPU communication.  
+  - For **L40 GPUs**: Use PCIe 4.0 for optimal bandwidth.  
+- **CUDA Multi-GPU Support**:  
+  Ensure Boltz is configured to use multiple GPUs (e.g., via CUDA-aware MPI or distributed memory frameworks).  
+
+---
+
+### **5. Storage & Performance**  
+- **RAM Sufficiency**:  
+  512 GB RAM is sufficient for most workloads, but monitor memory usage with tools like `htop` or `free -h`. Optimize Boltz to minimize memory overhead (e.g., batch processing).  
+- **Disk I/O**:  
+  Use NVMe SSDs for temporary storage (e.g., `/tmp`, `/var`) to reduce disk contention.  
+
+---
+
+### **6. Security & Monitoring**  
+- **Centralized Logging**:  
+  Set up a centralized logging system (e.g., ELK stack) to monitor server activity and GPU utilization.  
+- **SELinux/AppArmor**:  
+  Enable security modules (e.g., AppArmor) to restrict access to critical resources.  
+- **Prometheus + Grafana**:  
+  Monitor GPU utilization (`nvidia-smi`), network throughput (`iftop`), and storage I/O (`iostat`).  
+
+---
+
+### **7. Additional Tasks**  
+- **Backup & Recovery**:  
+  Set up regular backups for critical data (e.g., Boltz configurations, NFS mounts).  
+- **Disaster Recovery Plan**:  
+  Define steps for hardware failure (e.g., GPU replacement, network redundancy).  
+- **Documentation**:  
+  Document all configurations (Ansible playbooks, firewall rules, GPU settings) for future reference.  
+
