Wide Area Network (WAN)
SolarWinds Failover Engine supports sites with different subnets. In this
scenario, the primary and secondary servers in the SolarWinds Failover Engine
Pair will require unique Principal (Public) IP addresses in each subnet and a
unique SolarWinds Channel IP address in each subnet for each server . During
Setup, select the Use different IP addresses for Secondary (Recommended
for DR secondary) and specify the Principal (Public) IP addresses of both the
secondary server and the primary server in the pair.
SolarWinds Failover Engine , using multiple NICs, also supports sites with the
same subnet. In this scenario the SolarWinds Failover Engine shares a single
Principal (Public) IP address between the primary and secondary server making
it available on the active server. Although the SolarWinds Channel addresses
should be unique within the same subnet. During Setup, select the Use same
IP addresses for Secondary (Recommended for HA secondary) on the Principal
(Public) IP Address Configuration page and specify the IP address to be shared
by both servers.
WAN Requirements
WAN deployments require the following:
•
Persistent static routing configured for the channel connection(s) where
routing is required
•
One NIC minimum, two NICs (1 x Public and 1 x Channel) are
recommended
•
At least one Domain Controller at the Disaster Recovery (DR) site
•
If the Primary and DR site uses the same subnet:
◦
During install, follow the steps for a LAN or VLAN on the same subnet
◦
Both the primary and secondary servers in the pair use the same Public
IP address
•
If the Primary and DR site use different subnets:
◦
During install, follow the steps for a WAN
◦
The primary and secondary servers in the SolarWinds Failover Engine
pair require a separate Principal (Public) IP address and a SolarWinds
Channel IP address
◦
Provide a user account with rights to update DNS using the
DNSUpdate.exe utility provided as a component of SolarWinds
Failover Engine through SolarWinds Failover Manager Applications
> Tasks > User Accounts
◦
SolarWinds recommends integrating Microsoft DNS into AD so that
DNSUpdate.exe can identify all DNS Servers that require updating
