When it comes to high availability for a printing environment, Lexmark Printer Installer, by design, has you covered. This great product converts your entire organization into managed direct IP printing and enables IT administrators to deploy Lexmark Printer Support Phone Number drivers, and profiles from a simple console. Now, when a user prints, the job is sent directly from the user’s system to the Lexmark printer, eliminating the need for print servers and a single point of failure. Should the Lexmark Printer Installer server ever go down, users will still be able to print.
Larger enterprise customers may still desire that the print management capabilities of Lexmark Printer Installer be available at all times; they may even have SLA commitments to the business. With the release of Lexmark Printer Installer 17.1, an enterprise class of high availability is now supported. Lexmark Printer Installer now has the capability to support three methods for making your print management highly available:
Active/active high availability using load balancer, IIS web server farms and real-time database replication
Automated and manual failover to a warm standby using DNS
Database backup and restore
Active/active high availability is new to Lexmark Printer Installer 17.1. It’s a method of creating redundancy for both the web server and the database that makes up Lexmark Printer Installer. This now ensures that Lexmark Printer Installer admin console, portal, and client communication are always available.
The foundation of the active/active high availability is the separation of the application from the database. This allows the use of industry standard technology in making the database and web server redundant.
Lexmark Printer Installer utilizes MySQL master/master replication using global transaction identifiers (GTIDs) to ensure that data is written real-time to a redundant database. In the event that the primary database server goes down, Lexmark Printer Installer will automatically detect the failure and start using the secondary database server. The failed database can then be repaired and the GTIDs will restore the database back to full replication.
For web server redundancy, Lexmark Printer Installer is installed on multiple IIS servers that are configured within an IIS farm using application request routing (ARR) for load balancing. Lexmark Printer Installer utilizes Microsoft dynamic file system (DFS) to replicate and share content real-time across the web servers. IIS-farm can monitor the web servers and If one of the Lexmark Printer Installer web servers fail, the requests are simply routed to the web servers that are still online. The failed web server can then be rebuilt and added back into the IIS-farm and start responding to requests.
They say a picture is worth a thousand words:
This blog has focused on the latest active/active high availability capability released in Lexmark Printer Installer 17.1. There are, however, two other methods. These methods are used by multiple Lexmark Printer Installer customers. They are well documented on the Lexmark Printer Technical Support Phone Number site.
Automated and manual failover to a warm standby server using DNS
Database backup and restore
Based on your needs, you can use one of these methods to meet SLAs and provide a highly available print management solution to your company.
