For data and operational redundancy, Voyager PACS servers can be configured for local storage at clinic/hospital site with a replicated copy located at another location (i.e another hospital site or a data center).
Images can be accessed for reporting or clinical viewing through either the local storage or at the replicated storage data center. Status changes on either server are replicated back to the other server.
This configuration can also provides remote users with fast access to images due to fast upload speeds out of data centers. The server replication and mirror function is flexible and configurable for the user environment.
A PACS network can be configured to have a single site replication or can have multiple PACS storages that replicate into a single server allowing data redundancy and operational redundancy. Images are replicated to a second or even third site to provide additional redundancy or a single offsite long term storage repository.
Local hospital/clinical users would typically use the LAN to access their local images, while remote users could use either the hospital/clinic PACS or the remote data center PACS. Images that are stored in a data center can have a higher upload speed and therefore remote users can have fast access to images for reporting and clinical viewing.
The server replication and mirror function is said to be flexible and configurable for the user environment (i.e. can be immediately replicated or can be done overnight so as not to affect operations in medium to low bandwidth environment).
