INTERNAL: Configuration Considerations for High Volume IAS Server Requests

Anonym
Topic:
Customers who have a single IAS Server/Converter license and anticipate (or are already experiencing) a high volume of image requests from clients should consider adding additional machines to help with throughput. The IAS Server/Converter Administrator Guide chapter on configuration discusses additional options, if adding new machines is not feasible for the customer.

Discussion:
Should the customer decide to purchase additional machines and licenses, there are several ways in which they can set up their installation. The best configuration for the customer depends upon their intended use of the Server/Converter.

One solution is using a master/delegate configuration. For example:
  • If a high volume of image serving is likely, use the additional machine(s) to set up a master/delegate configuration on the Server. The distribution of image serving will free memory for conversions on the machine that also has the Converter.
  • If a high volume of image conversions are likely, use the additional machine(s) to set up a master/delegate configuration on the Converter. The Converter can handle heavier loads in this configuration, thus freeing memory to serve images on the machine that also has the Server.

If a master/delegate setup is not needed, the customer can also set up machines in a segregated manner to suit their needs. For example:

  • Separate serving and conversion functions so they are not on the same machine. Use one machine to convert images and another machine to serve images. On the Server, make sure the imagery directory is shared, so the Converter can access it. On the Converter, set the configuration parameters for Top Level Image Folder to the imagery directory on the Server, Restrict Converter Console Users to false, and (for Windows) add the UNC path of the Server imagery directory to Additional Converter Console Folders. Instructions to do this are in the IAS Server/Converter Administrator Guide.
  • Retain serving and conversion functions on the same machine, but distribute the workload by region or another workload distribution point. For example, if the customer has a large amount of regional imagery, they could maintain imagery from the Western region on one machine and imagery from the Eastern region on another machine.
