تهیه کننده : آرش قمبری Ver:1.2 EXCHANGE 2010 SP2 HIGH AVAILABILITY

Overview of Exchange Clustering: 1. Exchange 2003 (backend Role) 2. Exchange 2007 (Mailbox Role) * continuous replication (CR)

3. Exchange 2010 (Mailbox Role) * Continuous Replication (( Block mode(SP1) VS File mode(RTM))) * Data Availability Group(DAG) * Database Mobility * Incremental Deployment * lagged Mailbox database copy * Mailbox database Copy * Mailbox Resiliency & Site Resiliency * Shadow Redundancy (On Transport Roles) * Switchover & Failover * DB Size Limit to 2TB

Other changes related to Exchange 2010 HA: * Transport Dumpster keep MSG until replicate to all DAG nodes * Transport Dumpster on Mailbox * Online Move Mailbox * Shadow Redundancy * Third Party Replication API *Active Manager - runs on all DAG & manage switchover or failover - Primary Active Manager (PAM) manage switchover or failover and Best Copy Selection - Secondary Active Manager (SAM) provide information to cas & hub

Exchange 2010 Clustering Quorum Models: * Even Nodes -> File share Majority * Odd Nodes -> Node Majority
