72 Cobalt CacheRaQ 4 User Manual

Cluster deployment with an L4 switch

in an ISP

Installation notes

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

network interface.

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

Master.

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

through a hub.

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

redirection of cache requests.

Advantages

• You do not need a Cluster Master.

• This solution is scalable—you can have dozens of CacheRaQ 4s for each

L4 switch.

• This is the fastest, largest-capacity solution.

Disadvantage

• An L4 switch is expensive.
