HOSTKEY

An AI factory in as little as 14 days instead of six months — at a prepared site. NVIDIA DSX POD moves compute, networking, power and liquid cooling into pre-integrated modular units. The result: less time from hardware delivery to production tokens.

Server won’t boot? HOSTKEY Rescue mode lets you boot a temporary OS in memory, get root access and repair the system or recover data without reinstalling the server. Rescue RHEL is available now. SystemRescue, GParted Live and a Windows option are next.

Which LLM actually fits on one GPU? We tested DeepSeek, Gemma and Phi on a single RTX 4090 and compared VRAM use, context limits and inference speed. The key lesson: “fits in memory” does not always mean “runs well.” Read → hostkey.com/blog/226-how-to-…

HOSTKEY S3 now spans five countries: NL — Standard + Cold FR — Standard + Cold CH — Standard PL — Standard DE — Cold Cold in Poland and the UK are next. Docs → hostkey.com/documentation/co…

Dedicated server or cloud? We compare real AWS and dedicated configs, including GPU, egress and bandwidth, to find the actual crossover point for always-on workloads. Watch → youtube.com/watch?v=ACCuYvR2…

The GPU is fast. Can memory keep up? In a demo, SK hynix MARS shared and reused KV cache across servers and GPUs via CXL pooled memory. Our takeaway: for long-context and agentic AI, memory architecture is becoming an inference bottleneck.

Disk space issues in Linux usually grow silently — until systems break. This guide shows how to: • check disk usage • find large directories • identify storage bottlenecks 👉 hostkey.com/blog/209-how-to-…

The app is ready. We handle the server. Managed Applications from HOSTKEY include deployment, updates, infrastructure maintenance, security, scaling and 24/7 support. Early Access: ~25% off Explore → hostkey.com/apps/managed-app…

32,768 CPU cores in one AI rack. AMD Helion separates agent execution from model inference and lets operators tune CPU/GPU capacity to the workload. Our takeaway: agentic AI is turning CPU/GPU balance into an infrastructure decision.

RTX 6000 Ada or RTX PRO 6000 Blackwell? 48 GB vs 96 GB, roughly $8.5K vs $16K, and very different gains depending on the workload. We break down the real inference benchmarks and tradeoffs → youtube.com/watch?v=3YB6-KuT…

AI agents are becoming infrastructure workloads. OpenClaw explores a self-hosted approach where: • agents run inside your infra • workflows are fully observable • execution is controlled end-to-end 👉 hostkey.com/blog/208-what-is…

HPE's Gen13 plans: up to 256 cores in 1U or eight GPUs. DL525 is due later in 2026; DL585a in early 2027.

Your team chat. We handle the server. Managed Element Messenger runs in your browser, with HOSTKEY handling deployment and infrastructure maintenance. Explore → hostkey.com/apps/communicati…

The app is installed. Can you recover when it breaks? We tested apt, pip, Docker, Ansible and Nix for deployment, resource use and failure handling. See the results → hostkey.com/blog/211-ways-to…

Cloud GPU or dedicated? Count your monthly hours, storage and data transfer. We work through the costs and break-even point in our video. Watch → youtube.com/watch?v=HG2amAOc…

Choosing a dedicated server provider in Europe is an infrastructure decision, not just a pricing comparison. Key factors: • latency & location • network quality • hardware configuration • support model • compliance 👉hostkey.com/blog/207-best-de…

Digital Realty and Blackfuel are deploying a multi-megawatt AI inference platform in Barcelona with AMD GPUs and liquid-cooled Dell AI Factory infrastructure. ⚙️The key idea: bring inference closer to enterprise data through private, low-latency connectivity. For agentic AI, networking can matter almost as much as the GPU.

AMD Radeon AI Pro R9700 vs NVIDIA RTX A5000 — tested on real AI workloads. 🧠 DeepSeek R1 14B/32B, gpt-oss 20B, video generation, and Blender. We also cover Linux kernel and driver requirements, plus where AMD’s software stack still lags behind. Watch:

Vultr is placing a $1.2B order for AMD Helios AI Rack systems from HPE. ⚙️The interesting part: AI infrastructure competition is shifting beyond individual GPUs toward full rack-scale platforms combining compute, memory, networking, and cooling.
