Software Defined or Converged Infrastructure

Blog Post created by Hu Yoshida Employee on Nov 7, 2016

In the past few years, a lot has been written about software defined infrastructure. The main benefit of software-defined products is supposed to provide flexibility and the cost advantages of using commodity hardware. The problem with software defined is that someone has to develop and manage the software and software defined is only as good as the hardware behind it.




Infrastructure should be like an automobile. You buy an automobile for speed, fuel efficiency, utility or status, you don’t worry about assembling all the components yourself. Today’s automobiles are computerized. The car tells me when it needs service. I call up my dealer. He picks up my car and provides me with a loaner while the car is being serviced. I never have to spend my time working on the car or be without transportation while it is being serviced. I have no doubt that many of the parts in the car are software defined, but that is the car vendors concern and not mine. I simply use it.


That is how I view converged infrastructure like our Unified Compute Platform (UCP). This is a combination of software defined infrastructures that uses advanced hardware architectures. The UCP provides enterprise functionality like blade servers with LPARs, server and storage virtualization and active/active availability with full orchestration across these element managers which integrates into VMware, Microsoft, or Open Stack, and connects to public clouds like Azure and Amazon S3. This provides a better balance of opex and capex benefits through the consolidation of disparate datacenter technologies that can be acquired, deployed, managed, and supported as though they were a single system. The Business Value of Hitachi Unified Compute Platform was recently documented in an IDC white paper.


“IDC conducted interviews with four organizations that use UCP. IDC's study revealed that organizations derive significant business value from their investment in UCP. IDC believes that the surveyed organizations will achieve this value because UCP:

  • Enables organizations to benefit from improved performance and efficiencies from consolidating business applications on a reliable, agile, cost-efficient, and scalable converged infrastructure platform
  • Empowers IT departments to prioritize their resources by reducing the number of full-time employees (FTEs) required to manage IT infrastructure and reallocate their time toward other initiatives — 44% less time spent by the IT department on "keeping the lights on"
  • Improves productivity, resiliency, and reliability — zero instances of unplanned downtime per year with UCP and 50% fewer planned downtime instances
  • Accelerates the application development process — time to develop and deploy an application improved by an average of 39% for the surveyed organizations “


While UCP provides many opex and capex benefits, this study by IDC emphasizes the business benefits, through the accelerated development and deployment of critical business applications. The scalable and elastic nature of HDS' converged infrastructure platform has enabled organizations to support the development of new business applications by providing datacenter capacity as and when required. Application developers are now able to develop and deploy applications in four weeks less time on average compared with their previous environment. This amounts to average IDC computed benefits worth $32.7 million per organization over a five-year cycle! Read the full report to see how this is done.
