Microsoft SQL Server 2017 Standard - 50 User CAL Pack

SQL Server 2017 Standard User CAL 50-Pack: License Your Growing Team for Cross-Platform Database Access

Empower your entire team with secure, compliant access to your critical database infrastructure without breaking your budget. The Microsoft SQL Server 2017 Standard 50 User CAL Pack is a volume licensing solution designed for growing organisations that need to connect fifty named individuals to a SQL Server 2017 Standard instance. This is a perpetual, one-time purchase that licenses people, not devices, making it the most flexible and cost-effective model for modern workplaces where staff routinely switch between desktops, laptops, and remote sessions. SQL Server 2017 was a landmark release, marking the first time Microsoft's enterprise-grade database engine ran natively on Linux, and introducing intelligent features like adaptive query processing and automatic tuning. With this 50-pack of User Client Access Licences (CALs), you unlock that cross-platform power for your users, ensuring you remain audit-ready while giving your data professionals the tools they need to derive insights faster.

Key features and benefits

• Per-user licensing for maximum flexibility: Each User CAL is assigned to a named individual, granting them the right to access the licensed SQL Server 2017 Standard instance from an unlimited number of devices. This eliminates the need to purchase separate licences for a user's office PC, home laptop, and mobile tablet.
• Perpetual licence validity: This is a one-time purchase with no expiry date. Your fifty users will be licensed to access SQL Server 2017 Standard for the lifetime of the product, providing long-term predictability for your IT budget without recurring subscription fees.
• Cross-platform database engine access: SQL Server 2017 runs natively on both Windows Server and Linux (RHEL, Ubuntu, SLES). Your licensed users can connect to databases hosted on the platform your operations team prefers, breaking down traditional OS silos.
• Adaptive query processing: This intelligent feature automatically adjusts query execution strategies based on real-time runtime statistics. Your users benefit from faster query performance without manual intervention from database administrators, improving application responsiveness.
• Automatic database tuning: SQL Server continuously monitors query performance, detects plan regressions, and can automatically revert to the last known good execution plan. This self-correcting capability reduces performance troubleshooting overhead and maintains consistent database speed.
• Native graph database capabilities: Model complex hierarchical or networked relationships directly within the relational engine using node and edge tables. This allows your developers to solve connected-data challenges, such as fraud detection or social network analysis, using familiar T-SQL syntax without deploying a separate graph database.
• Resumable online index rebuilds: Database maintenance operations can now be paused and resumed at any point. This provides crucial operational flexibility, allowing large index rebuilds to be split across maintenance windows without losing progress if an interruption occurs.
• 50-user volume pack for growing teams: This pack provides exactly fifty User CALs, ideal for departments or mid-sized companies standardising their database access. It simplifies procurement and ensures you have licences ready as you onboard new data analysts, developers, or report viewers.
• Compliant licence reassignment: Should a team member leave or change roles, the User CAL can be permanently reassigned to a different named user after 90 days. This protects your investment and allows the licence pool to adapt to normal staff turnover.

What's included with your purchase

Upon completing your order, you will receive a comprehensive licence delivery package designed for immediate deployment. Your purchase includes a genuine Microsoft SQL Server 2017 Standard 50 User CAL retail licence key, delivered instantly via email. This is a full perpetual licence, not a monthly subscription or time-limited rental. Alongside the licence key, you will receive a direct download link to the official Microsoft SQL Server 2017 installation media, ensuring you get a clean, unmodified source file. A step-by-step activation guide is provided to walk you through the straightforward process of registering your licences. You will also receive a detailed VAT invoice suitable for business accounting and tax purposes. Please note that this pack provides the 50 User CALs required to connect individuals to the database; it requires an already licensed SQL Server 2017 Standard server instance, which is sold separately. The licence is compatible with SQL Server 2017 Standard running on Windows Server 2012 R2 or later, or on supported Linux distributions including RHEL 7.3+, Ubuntu 16.04+, and SLES 12 SP2+.

Licensing explained: what you need to know

Understanding Microsoft's server licensing model is essential for maintaining compliance. SQL Server 2017 Standard uses a server-plus-CAL model. This means you must first license the server software itself, typically using the core-based model where you purchase a licence for each physical or virtual core on the machine running SQL Server. Once the server is licensed, every individual user or device that directly or indirectly accesses the SQL Server data, queries it, or views reports from it must be licensed with a Client Access Licence (CAL).

This product provides User CALs, which are assigned to named people. This is distinct from Device CALs, which license a specific machine regardless of how many people use it. User CALs are the optimal choice if your employees access the database from multiple devices—for example, a company laptop, a personal smartphone, and a shared office desktop. With a User CAL, that single person is covered across all their devices. If you have shift workers sharing a single terminal, a Device CAL might be more appropriate, but for the modern, multi-device knowledge worker, User CALs provide the greatest flexibility and value.

Regarding virtualisation, SQL Server 2017 Standard edition allows you to run one instance of the software in a physical or virtual operating system environment. If you are using Software Assurance, additional virtualisation rights may apply, but under the base licence, you are licensed for a single instance. The 50 User CALs in this pack are valid to access any licensed SQL Server 2017 Standard instance within your organisation. It is also important to distinguish Standard from Enterprise edition. Standard edition includes the core database engine, basic reporting, and analytics, up to the lesser of 4 sockets or 24 cores, with 128 GB of memory. It is ideal for departmental databases and mid-tier applications. Datacenter edition, designed for large-scale data warehousing and mission-critical workloads, removes these limits and adds advanced features like infinite virtualisation. For most business applications, Standard edition provides an excellent balance of performance and cost.

System requirements / compatibility

To deploy this licence pack, you must have an existing Microsoft SQL Server 2017 Standard server instance. The server software is supported on Windows Server 2012 R2 or later, or on Linux distributions including Red Hat Enterprise Linux (RHEL) 7.3 or higher, Ubuntu 16.04 or higher, and SUSE Linux Enterprise Server (SLES) 12 SP2 or higher. The client devices used by your licensed users can run any operating system capable of connecting to a SQL Server database via ODBC, JDBC, or other standard connection protocols. The product interface and supporting documentation are available in multiple languages, including English, German, French, Spanish, Italian, Dutch, Polish, Portuguese, and Japanese. For the most granular and up-to-date hardware requirements for the SQL Server host machine, including processor speed, RAM, and disk space recommendations, we advise consulting the official Microsoft SQL Server 2017 documentation, as optimal specifications will vary based on your specific database size and workload.

Installation and activation

Your licence key is delivered digitally and will arrive by email within minutes of completing your purchase. The typical delivery time is under 60 seconds. The email contains your unique 50 User CAL licence key, a secure download link for the SQL Server 2017 Standard installation media, and a PDF activation guide. To begin, download the software from the official Microsoft source provided. If you are setting up a new server, you will install and activate the SQL Server 2017 Standard server licence first. The User CALs do not require a separate technical installation; they are a legal licence grant. You should maintain a record of your purchase and the licence key as proof of your 50 user licences in the event of a software asset management audit. If you encounter any issues during the server activation process, Lizensa provides free multilingual technical support to assist you. As this is a perpetual licence, you are entitled to reinstall the server software on the same or replacement hardware, provided you remain within the terms of the Microsoft Software Licence Terms.

FAQ — frequently asked questions

Is this a subscription or a one-time purchase?

This is a perpetual, one-time purchase. You pay once for the 50 User CALs, and they are yours to use for the lifetime of the SQL Server 2017 Standard product. There are no recurring monthly or annual fees.

What is the difference between a User CAL and a Device CAL?

A User CAL licenses a single named person to access SQL Server from any number of devices (PC, laptop, tablet, phone). A Device CAL licenses a single physical device, allowing any number of users to access SQL Server from that one machine. User CALs are generally more flexible for employees who use multiple devices.

How fast do I get my licence key?

Your licence key is delivered instantly. After payment confirmation, you will receive an email containing your key, download link, and activation guide, typically in under 60 seconds.

Is this a genuine and legal Microsoft licence?

Absolutely. Every licence sold by Lizensa is 100% genuine and sourced from authorised European distributors. You will receive a legally compliant licence that will pass any Microsoft software asset management audit.

What if I have trouble activating my server licence?

While the User CALs themselves do not require a technical activation key to be entered, if you have issues with your underlying SQL Server 2017 Standard server licence, our free multilingual technical support team is available to help you resolve the problem.

Can I reassign a User CAL if an employee leaves the company?

Yes. Microsoft's licensing terms allow you to permanently reassign a User CAL from one named user to another once every 90 days. This allows you to reallocate licences as your team changes.

What is your refund policy?

We offer a 14-day right of refund in accordance with EU consumer protection regulations. If you have not activated the licence and it is unused, you can request a full refund.

Do I need anything else to use this 50 User CAL Pack?

Yes. This pack provides the 50 user access licences. You must also have a separately licensed instance of Microsoft SQL Server 2017 Standard server software to which these users will connect.

Can these users connect to SQL Server running on Linux?

Yes. A key feature of SQL Server 2017 is its native support for Linux. Your 50 licensed users can connect to a SQL Server 2017 Standard instance whether it is hosted on a supported Windows Server or Linux distribution.
