Sizing the server
When sizing an InForm application server, be aware of the resources that are already being used. Make sure that you monitor the server(s) during the trials.
When sizing your server, consider the average number of:
- Sites.
- Patients per site.
- CRFs.
- Data items.
- Users.
For each trial, consider the:
- GCP status of the trial (GCP or non-GCP).
- Phase that the trial is in (1, 2, 3).
- Duration of the trial.
- Enrollment rate.
- Geographic proximity of server(s) to sites.
- System availability requirements.
- Number of sites.
- Number of users.
- Number of patients.
- Number of unique forms.
- Maximum number of items per form.
- Average number of items per form.
- Maximum number of rules per form.
- Average number of rules per form.
- Total number of forms per patient.
