Notes on Orchard Application Server Deployment

  • The Orchard application 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 Orchard deployment, you must have a minimum of 4 application servers. Additional Orchard application servers may be deployed for the purposes of scalability to accommodate larger volume organizations. The following metrics should be used when determining how many application servers to deploy:
ServerQuantityPurpose
Web Resource Server1The Resource Web Server controls specific processes for the Orchard Enterprise application such as direct printing, remote access printing services (RAPS), HL7 hosts, email, inbox delivery, etc.
HL7 Application Server1Metric: 1 application server per 75 HL7 messages/minute.
User Access Application Server1Metric: 1 application server per 300 concurrent users.
Device/Instrument Interface Application Server1Metric: 1 application server per 75 device instrument result messages/minute.
