Hello,

I've two database servers on which need to implement database clustering (Active/Passive).

Could you please assist how many IP required?

As per my understanding, I need to have 3 IPs i.e. 1 for interface and 2 virtual IPs.
Am I correct?

Best Regards,
Mohit Pandit

Public Network
1 IP for Cluster Name
1 IP per node for each defined Public Network (commonly 1 per node)
1 IP per MSDTC that you may required. MSDTC is not a pre-requisite for SQL or Failover Clustering but certain techologies (such as distributed transaction support) requires it. You can configure 1-Many Clustered MSDTCs depending upon requirements. Commonly one is put into each FCI Group. Note Windows 2008 supports local MSDTC on Cluster nodes too (though this is a configuration I never use for HA reasons).
1 IP per each SQL Failover Clustered Instance (FCI). Please note that in SQL Server 2012 Multi-Subnet clustering is supported so in that case, using that technology you may require 1 IP per subnet per FCI -obviously that is not your scenario though.

Private Network
1 IP per node for each defined Private Network (commonly 1 per node)

Storage Network (optional and used when Shared Storage is provisioned over iSCSI)
1 IP per node for each defined Storage Network (if iSCSI targets are used. SAN using HBA cards will not require this)
