Dedicated servers for Solana RPC Node Validators

Solana nodes are resource-hungry and really need enterprise-grade infrastructure to perform at their best. At minimum, we recommend:

• CPU: For smooth work, you’ll want to have a CPU with 24 cores and 48 threads. It should support AVX2 and SHA and for this, we consider that the AMD EPYC 4th Gen or the Intel Xeon Scalable is a great option.
• RAM: At a minimum 256 GB of ECC DDR5 RAM, but we suggest having 512 GB or more is better for future-proofing your server.
• Storage: We recommend that you get a 1 TB NVMe SSD for the OS, one more 1 TB NVMe SSD for account storage, and finally two 4 TB NVMe SSDs in RAID 0 to store your ledger data.
• Network: 3 Gbps as a minimum but we recommend 10 Gbps connection with unmetered traffic and low latency.

Yes. HOSTKEY offers Solana-ready configurations with the correct OS (Ubuntu 20.04 LTS), SSD layout, open ports (8000–10000, 8899), and support for NUMA, MTU 9000, and other Solana-specific kernel optimizations. You can choose from among instant setups or request a custom configuration tailored specifically to your needs.

Our Solana servers come with up to 10 Gbps uplinks to ensure your node maintains proper sync and avoids vote lag. This kind of high-throughput connection is a must for validators handling 80–100 TB/month of traffic and the best way to avoid issues during high-activity periods like airdrops or NFT launches.

Yes you can, HOSTKEY is open to Web3. We accept payments in crypto through BitPay, which works with major crypto-currencies such as Bitcoin, Ethereum and Stablecoin. Bear in mind that under EU law KYC verification is required for any crypto transactions.

HOSTKEY is strategically present in data centers all over the EU from our home base in the Netherlands to Germany, Finland, France, the UK, Spain, Italy and Iceland. Further afield, you can currently find us in the USA (New York) and Turkey. You can simply pick the site closest to your target Solana cluster to minimize latency and maximize performance.

No problem. HOSTKEY offers a wide range of default and custom server configurations designed to handle any number of performance needs from lightweight Solana RPC nodes to heavy-duty validator setups with massive memory and storage. No matter if you're just starting out or scaling a high-stakes infrastructure, you can choose the right hardware tier for your workload.

Scalability made easy. You can upgrade your servers or migrate to new ones with a bare minimum of downtime, and you can instantly deploy new configurations via our web-based control panel or powerful API. Our flexible approach makes it easy to deal with ledger growth, traffic surges or any new features added to Solana with little to no downtime.

HOSTKEY’s servers are only placed in Tier III+ data centers featuring advanced cooling, redundant power supplies and network uplinks. And yes, we do provide DDoS protection by default and will deliver it in writing in an SLA-backed uptime guarantee along with robust firewall policies to protect our customers from attacks targeting their public RPC ports and gossip protocols.

Certainly. Even though HOSTKEY’s infrastructure was built with Solana in mind, it does support a large number of leading blockchain networks including Ethereum, Sui, Aptos, Polygon, Avalanche, Arbitrum, Near, Cosmos, Polkadot, Mina, BSC and more. You are free to run validator nodes, archive nodes, RPC endpoints and indexers from multiple ecosystems.

Easily. HOSTKEY uses a comprehensive web-based control panel that lets you launch, monitor and manage your servers with just a few clicks. Also, we provide a robust API that allows developers to automate server deployment, configuration, reboots, OS reinstallation, and much more — scalability made easy for operations or CI/CD pipelines.
