Software-Defined Storage (SDS) may hold a lot of promise. But implementation can be far from straightforward. Organizations may have hardware and software dating back several generations. So what is the best way to go about it? When thinking about implementing a first-generation, software-defined storage solution, make sure to include much more than just the hardware and software costs as you calculate your total cost of ownership (TCO). Add in the extra space, power and cooling costs for a lab to implement and test a solution before putting it into production, and put in headcount costs (and expertise) needed to implement a solution. “These are all important costs that must be factored in as a part of all new software-defined solutions,” said Steve Kenniston, vice president of product marketing, Infinidat.
