Notes on System Web Server Deployment

  • The system web servers must maintain less than 1ms latency to the database server due to heavy transactional interactions.
  • In a virtual environment, the required memory must be 100% statically allocated or marked as reserved.
  • If automated faxing will be deployed, a physical server is required due to telephony requirements.
  • For any system deployment, you must have a minimum of 3 web servers (4 if using automated faxing). Additional system web servers may be deployed for the purposes of scalability to accommodate larger volume organizations. The following metrics should be used when determining how many web servers to deploy:
ServerQuantityPurpose
Web Resource Server1The Resource Web Server controls specific processes for the system application such as direct printing, remote access printing services (RAPS), HL7 hosts, email, inbox delivery, etc.
HL7 Web Server1Metric: 1 web server per 75 HL7 messages/minute.
User Access Web Server1Metric: 1 web server per 300 concurrent users.
Optional Faxing Web Server1Only necessary if utilizing automated faxing from system.
