Configure GSLB on Citrix ADC VPX instances 编辑

Citrix ADC appliances configured for global server load balancing (GSLB) provide disaster recovery and continuous availability of applications by protecting against points of failure in a WAN. GSLB can balance the load across data centers by directing client requests to the closest or best performing data center, or to surviving data centers if there is an outage.

This section describes how to enable GSLB on VPX instances on two sites in a Microsoft Azure environment, by using Windows PowerShell commands.

Note

For more information about GSLB, see Global Server Load Balancing.

You can configure GSLB on a Citrix ADC VPX instance on Azure, in two steps:

1. Create a VPX instance with multiple NICs and multiple IP addresses, on each site.
2. Enable GSLB on the VPX instances.

Note

For more information about configuring multiple NICs and IP addresses see: Configure multiple IP addresses for a Citrix ADC VPX instance in standalone mode by using PowerShell commands

Scenario

This scenario includes two sites - Site 1 and Site 2. Each site has a VM (VM1 and VM2) configured with multiple NICs, multiple IP addresses, and GSLB.

Figure. GSLB setup implemented across two sites - Site 1 and Site 2.

In this scenario, each VM has three NICs - NIC 0/1, 1/1, and 1/2. Each NIC can have multiple private and public IP addresses. The NICs are configured for the following purposes.

• NIC 0/1: to serve management traffic
• NIC 1/1: to serve client-side traffic
• NIC 1/2: to communicate with back-end servers

For information about the IP addresses configured on each NIC in this scenario, see the IP configuration details section.

Parameters

Following are sample parameters settings for this scenario in this document. You can use different settings if you want.

$location="West Central US"

$vnetName="NSVPX-vnet"

$RGName="multiIP-RG"

$prmStorageAccountName="multiipstorageaccnt"
