Scheme 1: the active and standby source IP is used for business access, and the new Nic is bound to IP for AG communication.

Test environment description:

Main library

TEST-GS-ZHXT1

Ethernet0

10.198.197.167

Ethernet1

10.198.197.173

DNS parsing:

Failover cluster configuration:

AG deployment:

1. Create communication endpoints for proprietary AG communication IP 173,174.

USE [master] GO/* Object: Endpoint [Hadr_endpoint] Script Date: 14:33:43 on 2018-6-26 * / CREATE ENDPOINT [Hadr_endpoint] STATE=STARTEDAS TCP (LISTENER_PORT = 5022, LISTENER_IP = (10.198.197.173)) FOR DATA_MIRRORING (ROLE = ALL, AUTHENTICATION = WINDOWS NEGOTIATE, ENCRYPTION = REQUIRED ALGORITHM AES) GO

two。 Create an availability group and specify ENDPOINT_URL as the exclusive AG communication IP.

Test:

1. Local and remote access to primary and standby source IP database services

Try to access through SSMS:

Can be accessed normally.

two。 Primary node downtime switch to standby node

Perform an AG failover manually, and then attempt to access the new primary node source IP database service locally and remotely:

Can be accessed normally.

3. Remove the backup node from AG and swap 10.198.197.167 with 10.198.197.168

First add a static route from the remote access exit IP to the server 167and168 Ethernet 1 interfaces to avoid Ethernet 0 disabling and enabling during the IP exchange to prevent RDP from being able to connect to the server.

Remove the standby node from AG

Connect to the server through 10.198.197.173 and disable Ethernet 0

Connect to the server by 10.198.197.174 and modify the IP of Ethernet 0 to 10.198.197.167

Connect to the server by 10.198.197.173, modify the IP of Ethernet 0 to 10.198.197.168, and enable the network card

From DNS queries to updates to

To observe that the state of WSFC is normal and that of AG is normal.

Node 1 Network connection switches to Ethernet 1

Node 2 IP of network connection Ethernet 0 has been switched

Attempt to access the primary and standby node source IP database service locally and remotely:

Can be accessed normally.

Summary:

Solution 1: Ethernet 1 will be recognized when Ethernet 0 is temporarily disabled during IP handover, so Ethernet 1 needs to add static routes in advance to ensure normal communication between WSFC and AG.

The first scheme can meet the needs of separate use of business IP and high-availability IP.
