StaQware allowed you to connect 2 RaQ 3i or RaQ 4i together via the 2nd 
Ethernet ports, effectively RAID over Ethernet.

It was problematic, and didn't live long. The RaQ kernels have long since been 
upgraded beyond what StaQware supported, and there never was a "public" OSRCD 
ISO -- you had to buy it -- so personally I'd just pretend you never heard 
about it, and check for something else.

We used to sell Polyserver as a clustering solution. PCI card add-in and some 
software kept multiple RaQs synched, or allowed functioning as a cluster. Not 
sure what their latest offerings include, and I'm sure there's no 
Cobalt-specific stuff anymore.

Depending on how real-time you wanted it, you could do something with an rsync 
script I'm sure.
