Configuring SPE Nodes

To configure load balancing, do the following:
  1. In System Configuration, select Global Configuration Settings > Workflows and Scanning > Scan Configuration > Scan Processing Engine Nodes.
  2. The Scan Processing Device Site Assignment page opens.
  3. Click Add to add an SPE node.
  4. In the Add SPE Node Parameters dialog box, do the following:
    1. Enter the SPE name or IP address.
    2. Select the Online checkbox.
    3. In SPE threads, select the number of scan jobs that can be simultaneously processed by SPE. Typically, scan processing is achieved quickly, and the default value of 5 is acceptable. However, complex operations such as OCR processing, can be time consuming. The value for SPE threads represents a balance between quick processing time and system resources.
    4. In OCR threads, select the number of simultaneous OCR jobs the system can perform. OCR jobs are typically CPU and memory intensive. OCR threads are a sub-set to SPE threads, and this number represents the number of SPE threads that are OCR jobs. This number cannot exceed the number of SPE threads.
    5. In the Scan job storage path field, enter the local folder used as a scan repository on the SPE server. This folder stores failed scan jobs until purged by the system.
    6. Enter the DNS name or IP Address of the Web server hosting the Equitrac Scan Client. This is necessary in order for SPE to include the URL link with outgoing emails.
      If the Equitrac Scan Client is running on the same machine as SPE, then enter the name of the SPE server. If the Scan Client is not running on the same machine as SPE, then enter the name of the IIS web server hosting the Scan Client.
    7. Select the SMTP connection from the drop-down list.
    8. Click OK to close the SPE Node Parameters dialog box.
  5. Click Apply to save the SPE nodes configuration.
