11 Exponential Growth in Data Centre Traffic Data Storage Array By 2018, 76% of global data centre traffic will come from Cloud services and applications High Performance Computing and Storage Storage Server Integrated Application Platform Seagate Confidential 11

12 Exponential Growth in Data Centre Traffic Most data centre traffic is internal 75% - 77% of data centre traffic through 2018 will be internal (East West) Due to separation of application servers, storage, and data bases, which generates replication, back-up and read and write traffic traversing the data centre Source: Cisco Global Cloud Index ( ) Seagate Confidential 12
