Chapter 6 Server Protection
When the vCenter Server Heartbeat pair establishes a connection, it triggers a file synchronization and
verification process to ensure all the files stipulated through file filters are mirror images of one another on
their respective servers. The process checks each 64K block of all protected files and performs a checksum to
find differences between blocks. When the checksum is the same, the block is marked as synchronized. When
the blocks are different, the block is replicated to the passive server and then marked as synchronized. The file
verification and synchronization process completes when all blocks of all files are marked as synchronized.
Configuring Heartbeat Settings
The Heartbeat interval dictates the time step at which the passive server sends Heartbeat packets to the active
server across the VMware Channel connections. Max Heartbeats Missed Before Failover determines the
number of missed packets before initiating a failover.
