IP Driver Software

Software for ZNYX Networks Ethernet adapters includes RAINlink technology to enable sophisticated High Availability applications for Carrier Grade and Service Provider environments. The underlying RAIN (Redundant Array of Independent Netports) technology is integrated with more than 20 drivers for 14 operating systems, which support various 10/100 Ethernet adapter cards with PMC, PMC/PIM, PCI and CompactPCI form factors. Adapters include 1-port, 2-port, 4-port and 8-port models. RAINlink enables adapters for HA applications with circuit availability of 99.999% or better. Services powered by RAINlink include:

Failover -- Eliminates downtime when a network connection fails. Enabled by configuring a server and subnet with 2-port connectivity. Transparent failover takes as little as 10 milliseconds. Automatic failback occurs when connection is reestablished, with no reconfiguration or change of IP address required. Failover may be used with Multi-Homing.
Multi-Homing -- Allows one server to communicate with two subnets. Provides system security with logical separation of network traffic; devices on one subnet are invisible to those on another subnet. Multi-Homing may be used with Failover.
Fault Tolerance -- Prevents single point of failure when using Failover and Multi-Homing by configuring server with two adapters, each communicating with both subnets. RAINlink allows simultaneous use of several ZNYX Networks adapters for complex network configurations.
Link Aggregation -- Combines two or more network links into a bonded trunk, which aggregates throughput from the separate connections for more bandwidth. In a CPU-to-CPU configuration, RAINlink Link Aggregation cuts transmission time in half -- with automatic failover and failback. Communications continue even if one channel fails in a multi-link trunk. Latter feature is called Load Balancing.
Load Balancing -- RAINlink load balances traffic across any trunk or groups of trunks to prevent interrupting network applications and services.
