Does a dental office need an on-site server or can it run in the cloud?
On this page
It depends on your practice management software. In 2026, Dentrix lists Windows Server 2016 through 2025 with 16 GB RAM for its database server (Henry Schein One). Cloud systems like Curve and Dentrix Ascend need no server, but they do need fast, reliable internet (Curve; Ascend).
Key facts
| Software | Server needed? | Key published spec | Source |
|---|---|---|---|
| Dentrix (2026) | Yes | Windows Server 2016/2019/2022/2025, 16 GB RAM, 4+ cores, 60 GB free SSD/NVMe, 1 Gbps | Dentrix System Requirements 2026 |
| Eaglesoft | Yes; dedicated server recommended at 6+ workstations | Windows Server 2016–2025 Standard or Windows 11 Pro; 16 GB RAM; RAID 1 drive | Patterson Eaglesoft Hardware Requirements |
| Open Dental (self-hosted) | Yes (dedicated recommended) | 1–10 workstations: dual core, Win 11 Pro, 4 GB RAM | Open Dental Hardware Requirements |
| Open Dental Cloud | No PMS server | 20 Mbps down / 10 Mbps up; ODCloudClient on Windows to bridge imaging | Open Dental Cloud Requirements |
| Dentrix Ascend | No | 50 Mbps down / 10 Mbps up for 10 concurrent logins | Dentrix Ascend System Requirements |
| Curve Dental | No | 10 Mbps down / 5 Mbps up minimum for 1–10 users | Curve Dental System Requirements |
How do I know which camp my software is in?
Ask where the patient database lives. If it's on a computer in your office, you need a server, or at least a dedicated computer acting as one. If it lives in the vendor's data center and you reach it through a browser, you don't.
- Local database: Dentrix, Eaglesoft and self-hosted Open Dental keep the database on a machine in the office (FloorStack).
- Cloud: Curve Dental and Dentrix Ascend run in a browser (Curve; Dentrix Ascend). Open Dental also sells a hosted version, Open Dental Cloud (Open Dental).
What do the 2026 server specs actually say?
They disagree more than you'd expect, so size to your vendor's document, not a generic "dental server."
Dentrix. Henry Schein One's April 2026 requirements list Windows Server 2016, 2019, 2022 and 2025, 64-bit, with 16 GB RAM (more for over 10 workstations), four or more cores at 2.4 GHz, 60 GB free on SSD or NVMe and a 1 Gbps network. Server Essentials and Small Business editions aren't supported because of port conflicts with backups. The document also says Dentrix has been tested on properly configured Hyper-V and VMware virtual machines (Dentrix System Requirements 2026).
Eaglesoft. Patterson's hardware document, for offices with nine or fewer workstations, calls for an Intel i5 (8th gen or later), 16 GB RAM, a 1 TB 7200 RPM drive in RAID 1 and gigabit Ethernet. It recommends a dedicated Eaglesoft server for six or more workstations (Patterson). Patterson supports Windows Server 2019, 2022 and 2025 to host the Eaglesoft server, with 2025 requiring Eaglesoft 24.20.03 or newer (Patterson Answer 39877).
Open Dental. For 1–10 workstations, Open Dental lists a dual-core CPU, Windows 11 Professional and 4 GB RAM for the MySQL/MariaDB server, scaling to Windows Server or Linux as workstation count rises. It notes that Windows 11 Professional allows up to 20 concurrent connections (Open Dental Hardware Requirements). It also recommends a dedicated server to protect data (Open Dental).
Two practical points. First, Henry Schein One says it stopped supporting new Dentrix installs on Windows 10 after June 30, 2026 (Dentrix 2026), so check workstation OS versions in any practice you're buying. Second, your imaging software often has its own server and storage requirements on top of the PMS.

To turn this into a drawing your low-voltage contractor can bid, the free network & IT plan generator (coming soon) is planned to produce drops, rack, Wi-Fi and VLAN plans from your floor plan.
If I go cloud, what still has to be in the office?
More than the brochure suggests:
- Windows PCs at the chair for imaging. Curve says Curve Capture isn't supported on terminal servers because it needs direct, local access to imaging devices, and that Schick imaging drivers need an Intel or AMD processor (Curve). Open Dental Cloud needs ODCloudClient installed on a Windows machine to bridge to imaging and card processing (Open Dental).
- Local image storage, in many setups, for speed. Large pano and CBCT files are slow to pull over the internet. Confirm with your imaging vendor.
- A much better internet connection. With no local server, the internet becomes the single point of failure, so a backup line stops being optional (FloorStack). See internet speed for a dental office.
Which is more secure?
Neither is secure by default. With a local server, your practice and IT provider are responsible for patching, backups, physical security and restores. With cloud software, the vendor runs the data center, but you still own access control, workstation security, email and your own backups of anything held locally.
HIPAA doesn't favor one or the other. HHS says a cloud service provider that handles ePHI is a business associate and needs a business associate agreement (HHS cloud computing guidance). CISA, writing for small businesses that struggle to keep internet-facing servers updated, encourages moving to reputable managed cloud providers to reduce, though not eliminate, maintenance work (CISA #StopRansomware Guide).
How does the choice change the build-out?
| Decision | Local server | Cloud PMS |
|---|---|---|
| Rack | Server, UPS, backup appliance | Smaller; firewall, switch, maybe imaging storage |
| Power | Dedicated circuit, UPS sized for the server | UPS for network gear |
| Internet | Important | Critical; plan a failover line |
| Backups | Local + off-site copies you manage | Vendor handles PMS data; you handle imaging and local files |
| Remote access | VPN or vendor tool, secured with MFA | Browser login, secured with MFA |
How FloorStack helps
The free FloorStack Studio plan starts from your software choice. Pick Dentrix, Eaglesoft, Open Dental, Curve or another system, and the plan tells you whether you need a server. If you do, it sizes the server from the vendor's published specs and builds the rack, power and backup layout around it. It's part of the FloorStack dental build-out platform. Start a free Studio plan, or see the Dental Office IT Setup hub.

Frequently asked questions
Can I run Dentrix on a regular Windows 11 PC as the server?
Henry Schein One's 2026 requirements list only Windows Server 2016 through 2025 in the server column, with Windows 10 and 11 listed for workstations (Dentrix 2026). Plan on Windows Server.
Can Eaglesoft run on Windows 11 Pro instead of Windows Server?
Patterson's hardware requirements list Windows 11 Professional (Eaglesoft 23.00.02 and higher) alongside Windows Server editions, and recommend a dedicated server at six or more workstations (Patterson).
How much RAM does a dental server need?
Dentrix and Eaglesoft both list 16 GB (Dentrix 2026; Patterson). Open Dental lists 4 GB for 1–10 workstations (Open Dental). Add more for imaging software that runs on the same box.
Does cloud dental software mean no IT provider?
No. You still need someone to secure workstations, the network, email, Wi-Fi and imaging PCs, and to keep internet failover working.
What internet speed does cloud dental software need?
Published minimums range from 10/5 Mbps for Curve to 50/10 Mbps for Dentrix Ascend at 10 concurrent users (Curve; Dentrix Ascend).
Is a cloud PMS a HIPAA business associate?
Yes. HHS says a cloud service provider that creates, receives, maintains or transmits ePHI is a business associate and needs a BAA (HHS).
