Processor: Dual-Core 3 GHz or better Processor
NOTE:8 cores provide optimal performance during initial archiving and re-indexing processes
Web server: Apache 2.4.x or IIS, installed and configured by a system administrator
Database: Supported SQL Database, installed and configured by a system or database administrator
RAM: Retain Server alone requires 8 GB RAM. Adding a worker increases the requirement to 12 GB RAM. The installation aborts if less is detected in either case. At least 16 GB is recommended.
Storage Space: As much storage space as messaging system requires. See Storage Planning
Swap Space (SLES/Linux): At least 10 GB.
Standalone Worker server: 4 GB RAM for server and one worker. 2 GB RAM for each additional worker.
Standalone Reporting and Monitoring server: 8 GB RAM
Standalone Router: 8 GB RAM
Memory needs vary, depending on the load and use of the Retain system. However, Java automatically tunes for the memory that is available on the server. Tuning depends on what is selected for installation.
The installation detects the amount of RAM and automatically assigns memory values as shown
Less than 16 GB system memory:
8 GB: Server and Worker
6 GB: Server only
Less than 20 GB system memory:
12 GB: Server and Worker
10 GB: Server only
More than 20 GB system memory:
16 GB: Server and Worker
14 GB: Server only
In all cases where only the Worker is installed, the memory is tuned to 3 GB.
