Equitrac print submission high availability for DRE

High Availability (HA) print environments are designed to provide full-time system availability. HA systems typically have redundant hardware and software that makes the system available in the event of a failure, and help distribute workload. To ensure that HA systems avoid having single points-of-failure, any hardware or software component that can fail has a redundant component of the same type.

Failures can be system faults, data errors and site outages. System faults can occur in the system itself (CPU, memory or power supply), the software (operating system, database or application), peripheral device error, power outage or the network disconnection. When failures occur, the processes performed by the failed component are moved (or failed over) to the redundant or backup component. This process resets system-wide resources, recovers partial or failed transactions, and restores the system to normal as quickly and as seamlessly as possible. A highly available system is almost transparent to the users.

This section details print submission high availability for Kofax Equitrac and highlights the various options to setting up highly available printer servers via Equitrac DRE. HA systems can be set up using Windows failover clustering, Windows Hyper-V clustering or Network Load Balancing (NLB).

Kofax assumes that you have already created, configured and tested your Windows cluster or Network Load Balancer (NLB) appliance. For information on creating clusters, or setting up NLB, refer to your Microsoft documentation.
