Most think that benefits are there for both phases of convergence (access layer versus end-to-end). We
asked respondents simply whether they thought there would be cost or operational benefits associated
with either edge-only (access layer) convergence or for end-to-end convergence. Interestingly,
perceptions of benefits are fairly consistent between capital cost and operational efficiency, as well as
between the two phases of adoption. Phase one benefits at the server access layer are slightly stronger in
the mind of respondents: 89% responded that there would be cost benefits, and 83% reported confidence
in the likelihood of operational benefits (see Figure 6). Considering phase two, respondents were also
fairly confident: 80% of respondents reported seeing both cost and operational benefits in the prospect.

Likely convergence benefits involve hardware and management synergy. We asked respondents to rank the
likely benefits of convergence separately for each phase of adoption. Regarding phase one benefits,
respondent perception leaned toward benefits related to the reduced cost of hardware and management
synergies (see Figure 7). In addition to these benefits, phase two responses also included consideration of
power, cooling, and data center benefits (see Figure 8). In both phases, the notion that the simplicity of
Ethernet would provide inherent benefits appears to have a much weaker likelihood of providing
significant benefits.

Interviewees pointed to concerns about maturity of the technology as a barrier. In our interviews with users
that have not yet adopted converged network environments, the interviewees stated that they felt that
there was not yet broad enough adoption of the supporting technologies to make it ready for their
consideration. This is in keeping with the conservatism of buyers in this category, who prefer not to be
early adopters of technology so central to critical operations. With the benefits case resonating with most
