Load Sharing
Load Sharing distributes traffic within a cluster of gateways so that the total
throughput of multiple machines is increased. In Load Sharing configurations,
all functioning machines in the cluster are active, and handle network traffic
(Active/Active operation). If any individual Check Point gateway in the cluster
becomes unreachable, transparent failover occurs to the remaining operational
machines in the cluster, thus providing High Availability. All connections are
shared between the remaining gateways without interruption.
High Availability
High Availability allows organizations to maintain a connection when there is a
failure in a cluster member, without Load Sharing between cluster members. In a
High
Availability cluster, only one machine is active (Active/Standby operation). In
the event that the active cluster member becomes unreachable, all connections
are re-directed to a designated backup without interruption. In a synchronized
cluster, the backup cluster members are updated with the state of the
connections of the active cluster member. In a High Availability cluster, each
machine is given a priority. The highest priority machine serves as the gateway
in normal circumstances. If this machine fails, control is passed to the next
highest priority machine. If that machine fails, control is passed to the next
machine, and so on.

Subject: [FW-1] Cluster - Load sharing/High availability
Dear CP gurus,
I have just one question regarding the clustering on NGX60.
High Availability
Will have 2 or more members. When the primary cluster down the secondary
will pickup. Without load sharing in between,
Load Sharing
Will have 2 or more members. Loan will share among members. For example,
When one of the cluster member die. All load will go to the active member.
So, I am not sure if I under that correctly. Please correct me if I am
wrong.
Because I want to setup a cluster firewall in my work area. I want to choose
the one which is suitable for me.
What I want is to have load share among the cluster members and I can patch
up one firewall without having a down time if needed. Does that mean Load
Sharing has the good bit of High availability plus load sharing? If it is,
why there is a High Availability options available?
Thanks in advance!
