How many IP addresses we require for setting up active/active SQL Server cluster?
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.
How many IP required for SQL Server clustering?
Types of IP Addresses You have two IP addresses for each cluster node, one IP address for the cluster and one for the liveCache cluster group. Some of the addresses are assigned to the network adapters (network interface card, NIC) whereas others are virtual IP addresses that are assigned to the cluster groups.
What is the use of Msdtc?
A requirement of MSDTC in SQL Server for distributed transactions. Microsoft Distributed Transaction Coordinator (popularly known as MSDTC) is a coordinator to handle the distributed transactions. A distribution transaction involves two or more databases in a single transaction.
What is the default value for lease timeout in WSFC?

What is difference between active-active and active/passive cluster?
In Active/Active Clustering, a set of companion nodes, a primary and a secondary, function in a relationship with their database. In an Active/Passive scenario, a single server runs on either the primary or secondary node.
What is a server cluster What are the two most common types?

How many IPs are required for SQL Server 2008 R2 cluster?
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).
How many IP address include in 2 node active-passive cluster?
If you need multiple NICs to get the required throughput then consider teaming the NICs (1 client team, 1 storage team) rather than using a dedicated IP address for each NIC. Some sites will split high-priority and low-priority data traffic into separate NIC teams each with their own IP address.
How many IP addresses do I need for my cluster?
The number of IP addresses you need depends on what you want to do and how your environment is built and what IP protocols you are using. The number of addresses you need will be the same regardless of if your cluster is Active/Active or Active/Passive.
