Minimum Hardware Requirements

We recommend you choose selecting your hardware and system requirements based on your real-world needs, such as your the number of users or expected patient records. NOTE:

...

...

• Recommended (10+ users): 8 Core+ processor, 16 GB RAM, 100+ GB HDD in RAID configuration, and with backup facilities

• Cloud Requirements (AWS):

  • Minimum: EC2 t3.medium (1-10 users)

  • Recommended: t3.large (8GB RAM, more processors) or higher, depending on the number of users

• Current O3 Demo Environments Specs:

  • The O3 Demo environment currently has: 16GB RAM 16GB, Disk 50GB disk space 50GB, and 4 CPUs (however, though we don’t actually use all of this).

Backups

It’s crucial to have a reliable backup strategy in place. Always have a RAID (Redundant Array of Inexpensive Disks)

fails,

Our Testing Process

Our automated performance and load testing, using Gatling in Q2 2024, is ongoing to review and confirm these minimum requirements.
