(Number of virtual IP can be different according to the customer's environment)
When configure Active-Standby server environment, virtual IP for service is managed in cluster and it should be the same bandwidth as IP of active and standby server.
Giga LAN is recommended for network for data mirroring.
Before installing MCCS, all network connection should be checked first through Ping test. Latest driver installation of NIC manufacturer is recommended for driver of network card.
| Warning |
|---|
When you assign an IP address on each NIC for service, heartbeat and mirror, Each IP address should not be on the same subnet among them. But each pair of them between nodes must be on the same subnet. |
IP Address
Each node in a cluster should have at least one IP address for every NIC to be used by MCCS. Virtual IP addresses which is switchable between nodes which communicate to clients also should be reserved. (The number of virtual IP address can be variable according to the clients' needs.)
When you reserve virtual IP addresses, this must be on the same subnet as the real IP address of the NIC of node. For example, if the real IP address of the NIC is 10.10.10.10/255.255.255.0, virtual IP addresses that MCCS uses on that NIC must be in the form 10.10.10.x/255.255.255.0 where x is any unassigned number from 1 to 254.
...
Firewall
