IO breakdown (estimates):

  • MS SQL (50% of our total IO)
    • 75% OLTP
    • 25% OLAP
  • MS Exchange (30% of total IO)
  • Generic servers (15% of total IO)
  • VDI (5% of total IO)

Capacity consuming apps:

Server Architecture

  • Traditional (Scale Up)
    • Client/Server – ERP, Filers, DBs
  • Converged (Scale Up)– VSPEC, VCE

  • Are you moving to total virtualization?
  • What business strategies are you grappling with fulfilling now? Into the future?
  • How do you see the data center contributing to business growth?
  • How quickly can you roll out new apps?.
  • What issues are you experiencing around technical readiness, implementation, monitoring and optimization?
  • What technical issues keep you up at night?

  • How do you expect the Cisco data center solution to help you?
  • Are you planning to deploy new applications,
  • Do you have any plans for data center growth or changes? Or are you adding new branches or acquired companies to the data center load?
  • What is your biggest challenge in the data center today?

LISTEN:

  • We struggle with planning around product lifecycles
  • There are too many access points/policies that are difficult to manage effectively.
  • We need to have air-tight security
  • We need hardware and software support for our remote workers.
  • We’re not getting efficient utilization out of our existing infrastructure.

ACT/Do:

  • Describe planning around business lifecycles instead of product lifecycles
  • Use the three-level architectural selling model :
  • Identify Current State – technical and business
  • Define Target State
  • Create Transition Roadmap
  • Know what the competition is offering, and why
