Liz Conner, research manager for storage systems at IDC said: "The enterprise storage market closed out 2015 on a slight downturn, as spending on traditional external arrays continues to decline.

"Over the past year, end user focus has shifted towards server-based storage, software-defined storage, and cloud-based storage. As a result, traditional enterprise storage vendors are forced to revamp and update their product portfolios to meet these shifting demands."
