Cobalt CacheRaQ 4 User Manual 75

Enterprise cluster with an L4 switch

Installation notes

• Conﬁgure the CacheRaQ 4s for Transparent Caching mode using one

interface.

• The CacheRaQ 4s can be connected either directly to the L4 switch or

through a hub.

• You do not need a Cluster Master because the L4 switch replaces the Cluster

Master.

• Refer to the manual of the L4 switch for instructions on conﬁguring the

redirection of cache requests.

Advantages

• This solution allows for high-speed clustering.

• It is fully scalable—you can add CacheRaQ 4s as needed. An L4 switch

typically places few limits on the maximum number of cache servers.

• It provides increased cache storage space.

• You do not need a Cluster Master.

Disadvantage

• An L4 switch is expensive.
