Hi all - Mike Arndt here, I am a NetApp Systems Engineer and have been working with Thomson Reuters in a variety of roles over the past 6+ years.
The Thomson Reuters infrastructure consists of pretty standard building blocks. They have between 25,000 and 30,000 x86 servers in their data centers, most with 2- or 4-CPU configurations. The network infrastructure is mainly 10-Gigabit Ethernetusing Cisco 6500 and Cisco Nexus 5000 and 7000 family switches.
The NetApp storage is offered internally as a shared service, or used in a dedicated fashion for certain very high performance requirements, and all NetApp storage is backed up using NetApp SnapShots and SnapVault for disk to disk replication.
