Most Important Considerations in Justifying IT Investments
11
Transformation is Underway
© 2012 Enterprise Strategy Group
• Business needs to react more quickly
• IT needs to become more agile
• Virtualization technologies enable transformation
• I/O under pressure

Data Center Networking Trends Overview
© 2012 Enterprise Strategy Group
• 280 IT professionals responsible for evaluating, purchasing, and managing data center networking technologies for their organization Included network architects, IT directors, data center managers Respondent organizations were required to be current users of server
virtualization technology (production and/or test and development)
• Enterprise organizations (i.e., 1,000 employees or more)
• North America only• Multiple verticals including manufacturing, financial,
government, health care, and communications

Server-to-Network I/O Interface Standards
© 2012 Enterprise Strategy Group 19
Our current standard server-to-network I/O interface is 1GbE; 31%
Our current standard server-to-network I/O interface is
1GbE, but we are actively mov-ing to 10GbE; 47%
Our current standard server-to-network I/O
interface is 10GbE; 20%
Don't know; 2%
Primary Drivers for Adoption of 10 GbE I/O Interface
© 2012 Enterprise Strategy Group 20
Vendors are more actively selling the technology
New types of applications (i.e., analytical applications, scien-tific applications, etc.)
Greater use of server clustering or more direct server-to-server (or direct memory) communications (i.e., RDMA)
Network convergence of communications and storage (i.e., iSCSI, FCoE, etc.)
We are making this transition due to the fact that 10GbE server-to-network I/O interfaces come standard on new
servers
Current or future implementation of a private cloud in our data center
Data center consolidation is driving massive data center scale
Costs have decreased to an acceptable level
Current or anticipated data center traffic
Server virtualization increases throughput requirements (i.e., multiple virtual machines per single physical server)

Drivers for Converged Data Center Networks
© 2012 Enterprise Strategy Group 22
Our networking vendor is helping us make this decision by providing converged networking equipment and guidance
We believe converged networking technology is mature enough to make this change
Reduce capital costs by converging all traffic on common hardware
We believe that a converged data center network in-frastructure will simplify our network architecture
Reduce operating costs and overhead
