You can use secondary servers to do some of the more processing-intensive steps in the various workflows and to prevent the primary server from becoming overloaded. The primary server works with the secondary servers to coordinate the movement of all jobs across the system. The secondary servers do not have their own embedded databases for storing system information. All the servers work with the database that is installed on the primary computer.
Secondary servers can manage all types of Ricoh ProcessDirector objects, such as input devices, steps, and printers. They can also run external programs that Ricoh ProcessDirector accesses through external steps. External programs can do more processing or special types of processing.
For installations that have many printers and a high volume of jobs, adding secondary servers to the system can increase job throughput. The throughput increases because each server has a smaller number of printers and jobs to monitor and control.
For AFP printers, you can set up secondary servers to stage work to the remote server so that Ricoh ProcessDirector keeps the pipeline to the printer full, reducing the likelihood that the printer waits for data. This configuration is particularly useful if you installed Ricoh ProcessDirector on an externally hosted or distributed network, such as a virtualized or cloud environment that is far removed from the physical printers. Properties of the AFP printer object allow you to specify a directory on the secondary server to receive the print files. The secondary server then manages releasing jobs to the AFP printer when the printer needs work.
You can create secondary servers on the primary computer or install the Secondary Server feature on these systems:
- AIX Version 7.2, Technology Level 02 or later
- AIX Version 7.1, Technology Level 04 with SP02 or later
- Red Hat Enterprise Linux 6.7 through latest 6.X
- Red Hat Enterprise Linux 7.1 through latest 7.X
- SUSE Linux Enterprise Server (SLES) 11.0 with Service Pack 3 or above for x86_64
- SUSE Linux Enterprise Server (SLES) 12.0 with Service Pack 1 or above for x86_64
If you define a Ricoh PDF or Custom PDF printer object on a Linux secondary server, the server must run one of these operating systems:
- Red Hat 7.1 through latest 7.X
- SLES 12.0 with the latest Service Pack for x86_64
Ricoh PDF printer objects represent supported Ricoh printers that can print PDF files. Custom PDF printer objects represent PostScript printers that are not on the list, including PostScript printers from other manufacturers.
