First decide where everything should be installed. Once the support and core components are installed, using Retain is the same no matter what platform it is installed on.
VMWare ESX and ESXi are supported. All components disk space, RAM, and other requirements apply as for physical hardware deployments.
Retain components can be deployed in various configurations, which can impact the requirements of the Retain server, indexing engine, database server, and so on.
Ultimately the number of active users in the system determine the resource needs of the system. See Retain Planning and Design Best Practices for details.
Dual-Core 3 GHz or better Processor
NOTE:8 cores provides the best performance during initial archiving and re-indexing processes
Apache 2.2.x or IIS, installed by system administrator
Supported SQL Database, installed by system or database administrator
Retain Server requires 8 GB RAM, unless a worker is installed then 12 GB RAM, installation aborts if less is detected, 16 GB is recommended
Storage Space: As much storage space as messaging system requires. See Planning Retain Storage Requirements
Swap Space: If using SLES/Linux the swap partition should be at least 10 GB.
Standalone Worker server requires 4 GB RAM, plus 2 GB RAM for each additional worker
Standalone Reporting and Monitoring server requires 8 GB RAM
Standalone Router server requires 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 assign 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.
Assuming that the Retain Server, Retain Worker, Database, and Index engine are housed on the same machine and archiving less than 500 active mailboxes.
The Retain Message Router should be installed on a dedicated server in the DMZ.
16-24 GB RAM
Assuming that the Retain Server, Retain Worker, and Indexing engine are on one server, and the Database is on its own server.
500-5,000 active mailboxes:
12-16 GB RAM
5,000-30,000 active mailboxes:
16-32 GB RAM
50,000 Active mailboxes
16+ GB RAM for Retain Server (depending on environment)
RAM as required for Database on separate server
Retain Workers installed remotely on each post office in the message system
Disk Space is dependent on the amount of email being archived and length of retention time. It is recommended to estimate two years of storage and adding additional space as needed. Storage speed is the determining factor for performance.
SAN and local storage preferred.
NAS is not supported.
The High Performance Indexer can be installed on multiple external servers as the High Availability Indexer. This requires at least three (3) dedicated indexing servers and a separate license. Contact Support for more information.
