SSD or M2 (preferred) disk with RAID is strongly recommended for best performance and reliability. 30-50 GB for database storage and 100-500 GB for documents, attachments and SCM repositories. The size of the required storage strongly depends on the size of documents, attachments and SCM repositories managed by codeBeamer.
Active/concurrent Users refers to the number of users which are actively (concurrently) working in codeBeamer at a given time, e.g. creating, editing Work Items, adding Comments and/or other artefacts.
The number of registered users (accounts) may be a much higher number than the number if concurrent users, so this guidance should be used to refer to the total number of expected active (concurrent) users.
For network connections between the codeBeamer ALM server and the database, low latency time connection (less than 1 ms) and at least 10Gb network bandwidth are required.
