f the biggest challenges of software defined storage is overcoming objections from data array customers who have invested time and money in their data storage systems. Existing storage arrays already have their own data and storage management software, and IT managers are already paying for some form of storage management- services. Another unknown factor is cost. Since SDS is largely cloud based some vendors are charging by the amount of data stored. However, customers really end up paying for the amount of data managed, since they have already paid for much of the storage devices already. Too Many Vendors Since SDS is still a young technology there are at least 20 different SDS vendors eying for market share and each with a different approach. One of the challenges of software defined storage is a lack of common understanding; everyone is talking about SDS but it means something slightly different for each vendor or analyst. It's Not baked Yet And as with any new technology, vendors are still working the bugs out of the deployments. SDS is a concept that is still evolving. It is surely coming, but it's not here just yet SO vendors are still wooing early adopters willing to take the long view that the SDS-market-will-mature.

For those used to running conventional data centers, the idea of using software defined networking, let alone storage as a service, is still very foreign and it will take some time for them to embrace it. CONCLUSION After going through the challenges that are faced by the existing storage solutions and the promises SDS through SDI is providing and the solutions developed by the companies it seems quite feasible that the SDS in future will come up with solutions that are capable of solving current and future software problems. The SDS is new technology and SDS solutions are also being
