SAP Business One Hardware Requirements: Free Server Sizing Calculator
How big a server does SAP Business One need — in your office or in the SAP B1 cloud? Enter your users, database and files and get a starting processor, memory and disk size for every server you need — one Windows server on SQL Server, or a Linux database server plus a Windows server for users on SAP HANA — based on published guidance from SAP, Microsoft and AWS, with an indicative monthly price on our Cloud for SAP.
Estimate your SAP B1 server size
Takes under a minute. Nothing you type leaves your browser.
Where official SAP Business One hardware numbers come from
SAP publishes a Hardware Requirements Guide for each SAP Business One release. Our free calculator uses the public sizing tables from Microsoft and AWS (linked on this page), so you can get a first estimate without a login. Always size for the busiest hour, not the average.
Example results
Worked examples for 10, 25 and 50 people working at the same time, with a 50 GB database, 20 GB of files, 20% growth a year and add-ons in use.
| Concurrent users | Database | Suggested processors | Memory | Disk |
|---|---|---|---|---|
| 10 | SQL Server | 8 vCPU | 64 GB | 163 GB |
| 25 | SQL Server | 16 vCPU | 72 GB | 163 GB |
| 50 | SQL Server | 30 vCPU | 136 GB | 163 GB |
| 10 | SAP HANA | Linux 8 + Windows 4 vCPU | Linux 64 GB + Windows 64 GB | Linux 274 GB + Windows 77 GB |
| 25 | SAP HANA | Linux 8 + Windows 8 vCPU | Linux 64 GB + Windows 64 GB | Linux 274 GB + Windows 77 GB |
| 50 | SAP HANA | Linux 16 + Windows 14 vCPU | Linux 128 GB + Windows 72 GB | Linux 478 GB + Windows 77 GB |
These are worked examples from the calculator above, based on the Microsoft and AWS sizing pages it uses. Enter your own numbers for your answer.
How many servers does SAP Business One need: SQL Server vs HANA
| SAP B1 on SQL Server | SAP B1 on SAP HANA | |
|---|---|---|
| Servers | One Windows server | Two servers: one Linux, one Windows |
| Where the database lives | On the Windows server (SQL Server) | On the Linux server (SAP HANA) |
| Where users work | Users log in to the same Windows server by Remote Desktop and run SAP Business One there | Users log in to the Windows server by Remote Desktop; SAP Business One there connects to the HANA database on Linux |
| Disk to plan | Windows + SAP programs, the database, your files, and backups | Linux: HANA data, log and shared areas plus backups. Windows: Windows + SAP programs and your files |
So for 20 people on HANA, all 20 log in to the Windows server, and that one Windows server talks to the HANA database on Linux. The calculator sizes both servers — processor, memory and disk — separately.
Named users vs concurrent users
Named users are everyone who has a SAP Business One login. Concurrent users are the people logged in and working at the same moment — and that is what drives server size. To find your number, ask your team how many people are typically working in SAP at the busiest hour of the day, such as month-end or the morning dispatch rush.
Where these numbers come from
- SQL Server: Microsoft's rough sizing for the SAP Business One database server — up to 20 users: 4 vCPU and 16 GB memory; up to 40: 8 vCPU / 32 GB; up to 80: 16 vCPU / 64 GB; up to 150: 32 vCPU / 128 GB. Source: Microsoft Learn — SAP Business One on Azure Virtual Machines.
- SAP HANA: server sizes SAP has certified for SAP Business One, version for SAP HANA, with the maximum concurrent users for each — for example 8 vCPU / 64 GB for 25 users, 16 / 128 GB for 50, 32 / 256 GB for 100 and 48 / 384 GB for 150. Source: AWS — SAP Business One certified instances, version for SAP HANA.
- Windows server where users log in: SAP's rule for Remote Desktop servers — 8 GB memory for Windows plus 1 GB for SAP Business One and 0.25 GB for the session and add-ons for each person working at the same time; each virtual processor supports fewer than five people (we use four); 0.5 Mbps of internet per person (see the internet speed calculator); 32 GB system plus 10 GB data disk. Source: SAP Business One Hardware Requirements Guide, sections 2.1 and 2.5.
- HANA disk on the Linux server: 50 GB for the system and SAP programs, HANA data 1.2 × memory, HANA log 0.5 × memory (between 50 and 500 GB), HANA shared equal to memory (up to 1 TB), and local backup space 3 × memory. Source: AWS — Calculate storage requirements for SAP HANA.
- Our starting size: each of our cloud servers for SAP Business One starts at 64 GB memory, even when the guides above allow less.
- Growth: we grow your current database and files by your yearly growth rate for three years.
These are starting points published by SAP and the cloud providers, not a quote. Real sizing also depends on how many documents you post, heavy reports, add-ons and integrations.
SQL Server or HANA — which needs more server?
HANA keeps working data in memory, so for the same number of users it needs far more memory than SQL Server — and HANA memory must match your SAP licence. SQL Server is the lower-cost default for most single-company manufacturers; HANA earns its cost when you have several plants, large data volumes and a real need for live analytics. Try the HANA vs SQL Server chooser.
On our Cloud for SAP you don't buy or size hardware yourself: we run SAP Business One on SQL Server or HANA on servers in a Mumbai data centre, with automatic daily backups and monitoring, and resize as you grow.
Frequently Asked Questions
How much RAM does SAP Business One need?
For the SQL Server database, Microsoft's starting point is 16 GB for up to 20 users, rising to 128 GB for up to 150 users. SAP HANA needs much more — SAP-certified HANA servers start at 64 GB for 25 concurrent users. On top of that, the Windows server where people log in by Remote Desktop needs 8 GB plus about 1.25 GB per person working at the same time. Use the calculator above for your numbers.
What is the minimum server for SAP Business One?
There is no single minimum that fits everyone; it depends on users, database and add-ons. Published guides size small SQL Server systems (up to 20 users) at 4 vCPU and 16 GB memory for the database alone. For a smooth SAP Business One server, our cloud servers start at 64 GB memory.
Does HANA need a bigger server than SQL Server?
Yes. HANA is an in-memory database, so it needs considerably more memory, and the memory must match your SAP HANA licence.
How many servers does SAP Business One on HANA need?
Two. SAP HANA runs on a Linux server, and a separate Windows server runs the SAP Business One client that your users log in to by Remote Desktop. On SQL Server, the database and the users can share one Windows server.
How much disk space does SAP Business One on HANA need?
On the Linux server, plan about 1.2 times the server's memory for HANA data, half the memory for the HANA log (50 to 500 GB), the same as the memory for HANA shared, plus 50 GB for the system, and backup space on separate storage. The Windows server needs about 42 GB for Windows and SAP programs plus your files. The calculator works this out for you.
Is this sizing or price a quote?
No. The server sizes are a starting point from published guidance, and the monthly price is indicative only. For your exact price, send us your details and we email you a written quote. If you want us to set everything up, there is also a one-time setup charge at the start.
Do I need to buy a server if I use your cloud?
No. On our Cloud for SAP we provide, run, monitor and back up the servers in a Mumbai data centre; you pay a predictable monthly cost in INR.
How many concurrent users does my SAP Business One server need to handle?
Count the people logged in at the busiest hour of the day, not everyone who has a login. That number - concurrent users - is what decides server size.
