Frequently Asked Questions
Do I need to purchase User CALs separately?
No. This 40-core Enterprise license includes unlimited User CALs, meaning any number of users can connect to the server without additional licensing costs. This is a key advantage of the per-core model over server + CAL licensing.
What does “40 core” mean for my server?
SQL Server 2025 Enterprise is licensed per-core. A 40-core license covers servers with up to 40 physical cores. Enterprise edition has no hard cap on cores — the license defines how many cores you’re purchasing coverage for. Contact us if you need coverage for a larger core count.
Is this a subscription or a one-time purchase?
This is a perpetual (lifetime) license. You purchase once and own the right to use SQL Server 2025 Enterprise indefinitely — no annual renewals, no expiration.
How quickly will I receive my license key?
Delivery is electronic and typically instant — your product key and ISO download link are emailed within minutes of order confirmation, any time of day or night.
Does SQL Server 2025 support AI workloads?
Yes. SQL Server 2025 Enterprise features native vector search powered by DiskANN, T-SQL-based AI model management, and direct integration with Azure OpenAI, Azure AI Foundry, and Ollama — purpose-built for modern AI development and RAG patterns.
What’s the difference between SQL Server 2025 Enterprise and Standard?
Enterprise removes all compute, memory, and availability limits — unlimited cores, unlimited memory, up to 8 Always On replicas, and 16 failover cluster nodes. Standard edition is capped at 32 cores and 256 GB of memory. For large-scale, mission-critical workloads, Enterprise is the appropriate choice.
