SGLang vs vLLM for enterprise LLM inference!
SRE Production & Benchmark Blueprint:
• VRAM OOM Trap: Don't set 0.9 VRAM! CUDA Graph capture exhausts host RAM. Use 0.8.
• FlashInfer Fix: Install ninja-build to prevent compilation failures.
• Agent Benchmark: SGLang RadixAttention yields 5x faster TTFT for agents.
• Security Warning: Never bind --host 0.0.0.0 without auth. -

Virtualize Game Dev: NVIDIA Blackwell SRE Review
The 48-user VRAM claim on 96GB Blackwell servers is a total illusion. Unreal Engine 5 needs 12-16GB per user just to boot—meaning 6-8 creators max per physical card.
Evade the Broadcom software subscription tax by utilizing open-source Proxmox VE. Implement strict NUMA node pinning to prevent shader compilation crashes from freezing adjacent workspaces.

Acronis vs JetBackup: The Brutal SRE Infrastructure Review
Cloud backups aren't safe if local API keys leak. Ransomware will authenticate and wipe your offsite archives too.
Comparing JetBackup (File-level) vs Acronis (Block-level) on ServerMO baremetal.
The "instant bare-metal restore" is a marketing myth. Downloading 4TB of block-level image data from the cloud is bounded by network physics. It takes hours.
Adopt the 3-2-1-1-0 architecture.
