Redundant Appliance Hardware Components

The components of Redundant Appliance address and eliminate common points of potential failure. The server hardware is built around an Intel-based mother board with 1GB of memory, 2MB cache, and dual 100/1GB NIC connections. It includes a RAID 1 controller, two serial 80GB disk drives, two removable power supplies, and fans.

Duplicated and backup hardware components provide increased reliability for business-critical faxing. Its server-class hardware closely monitors the system, sending notification to the administrator in the event of a failure.

Automatic Failover

Redundant Appliance can also be configured for single or multiple digital connections to allow for automatic failover if the connection to the service provider is lost.

T1, E1 and ISDN Configurations

The Redundant Appliance T1 can be installed with a fractional T1 board to provide 8 channels across a fractional T1 line, dual fractional T1 boards, or one to three T1 fax boards to support from 24 to 72 channels across a T1 line(s).

For international markets, Redundant Appliance is available in an E1 configuration with support for fractional E1, dual fractional E1, or full E1 up to 90 channels, and ISDN configurations from 2 to 24 channels per server.
