Last I heard it was called RaQ StaQware, and as far as I can tell it was 
only available for the RaQ3...
Below is a snippet from a website about it.
Just do a google on "RaQ StaQware" (without the inverted commas).

There are other linux programs (such as HeartBeat) that provide clustering 
/ failover solutions, but I'm not sure how effective such solutions would 
be on a RaQ...

Kam.

The Cobalt StaQware High Availability Cluster Software for RaQ 3i is a 
software package that provides a high-availability failover solution and 
real-time data replication for a pair of Cobalt RaQ 3i servers. The 
software enables a RaQ 3i that is providing services (for example Web, 
email, file transfer protocol [FTP] and Domain Name System [DNS] service) 
to fail over to a second RaQ 3i in the event that the first RaQ 3i is 
detected as being offline.

Cobalt¹s StaQware Cluster solution, implemented on a pair of identical RaQ 
3i servers, is designed to protect customers against hardware failure. 
There is an active RaQ and a standby RaQ in the pair. The active RaQ is the 
live machine that services incoming requests; the standby RaQ monitors the 
active RaQ and is prepared to take over all services for the active RaQ in 
the event of failure. Through the primary network interface, both RaQ 3i 
servers monitor the health of their pair partner and verify connectivity to 
the Internet (by accessing the gateway). Data synchronization and 
peer-to-peer communication take place over a second ethernet channel. The 
two RaQ 3i servers must have the same SKU number because the hard drives in 
the two RaQ 3i servers must be the same size.

The StaQware Cluster offers:

* automatic failover between a pair of RaQ 3i servers
* real-time data replication
* reduced downtime of services
* maintenance through planned failovers and service intervals
