EMS System Requirements - 226

This topic lists the system requirements for EMS products.

Network and Other Considerations

  • The default port used by your SQL Server Native Client Configuration must be accessible from your application servers.

  • Your end users and devices, such as room signs and kiosks, need network access to your application servers through port 443.

  • If you integrate with Microsoft 365 Exchange Online or other third-party services, you might need to open parts of your EMS environment to the internet through port 443 or allow the relevant IP addresses.

  • If you use a load balancer, run each EMS Windows service on only one node at a time. These services include Email Notification, Check-in Notification, Automated Report, and Campus Auto-Sync.

Database Server Minimum System Requirements

  • Processor: 2.0 GHz and 4 cores or faster

  • Memory: 8 GB or more*

  • Hard-Disk Space: Two separate physical drives of at least 6 GB, one for data and one for transaction logs. SCSI drives with 9 ms access or better and a RAID strategy for fault tolerance are recommended.

  • Network Card: 100/1000 Mbps Ethernet, switched

*Specifications support up to 100 concurrent users. Increase the specifications for more than 100 concurrent users.

Notes

Application Pool

.NET CLR Version v4.0

Enable 32-bit Applications = False

Managed Pipeline Mode = Integrated

Configure each EMS application to use the application pool settings appropriate for its .NET version. Use No Managed Code for modern .NET applications and v4.0 for .NET Framework applications.

This guidance applies to Campus Web Service, EMS Kiosk App, EMS for Outlook REST API, EMS Platform Services, and other EMS web applications hosted on the same server.

EMS for Outlook REST API requires Enable 32-bit Applications = True.

EMS for Outlook REST API and EMS Platform Services perform better with .NET CLR Version = No Managed Code but can run under v4.0.

The installer creates EMSAppPool in IIS. If EMSAppPool already exists, the installer overwrites changes made to this pool. If you install multiple applications on an application server, run the installer before you make application pool changes required for your environment.

We recommend that you use separate application pools for EMS applications. Separate application pools can improve performance and help prevent configuration changes for one application from affecting other applications.
