  *Figure 12-2 Horizontal scaling: Multiple object servers (z/OS and Multiplatforms)*
  
  This form of horizontal scalability provides better performance, reliability, and scalability by 
  distributing the storage and retrieval workload over multiple systems. 
  
  From a Content Manager OnDemand perspective, no limit exists to the number of object and 
  load process servers. Each of the servers can run to its maximum capacity. Operational 
  limitations are imposed by the TCP network bandwidth that connects all of the servers and by 
  the available data center floor space. Both of these constraints can be reduced by placing 
  multiple servers in a rack-mounted configuration.
