CacheRaQ ISP Cluster Deployment
Installation Notes
• Configure one CacheRaQ as the Cluster Master, as
explained in "Cache Setup" on page 17.
• Configure the Cluster Master to operate in
Transparent mode using one network interface.
• The Cluster Slaves require no special configuration.
• Configure the CacheRaQ’s gateway to be the router’s
IP address.
• Configure the access concentrators (“DIAL UP”) to
use the Cluster Master as their gateway.
Advantages
• Clustered CacheRaQs provide high-availability and
high-speed cache access and larger cache storage.
• This solution is scalable — you can add up to 5
Cluster Slaves.
Disadvantage
• You can’t have more than 5 Cluster Slaves; if you
want more capacity, you can use the L4 switch
solution (described on the next page).
