text: **Synchronous replication**
  Synchronous replication is a type of replication in which the application write operation is 
  made to both the source volume and target volume before control is given back to the 
  application. See also “Asynchronous replication” on page 770. 
  
  **Tie-break**
  In a case of a cluster split in two groups of nodes, tie-break is a role of a quorum device used 
  to decide which group continues to operate as the system, handling all I/O requests. 
  
  **Thin-provisioned volume**
  A thin-provisioned volume is a volume that allocates storage when data is written to it. 
  
  **Thin provisioning**
  Thin provisioning refers to the ability to define storage, usually a storage pool or volume, with 
  a “logical” capacity size that is larger than the actual physical capacity that is assigned to that 
  pool or volume. Therefore, a thin-provisioned volume is a volume with a virtual capacity that 
  differs from its real capacity.
