One area which organisations can focus on for economic efficiency and sustainability improvements is in the data centre. To understand why, we need to review the significant changes which have occurred in data centres in recent years. In fact, it started back in 2011, when Pure Storage released the first all-flash storage array that was robust and economical enough for mission-critical data centres. Ever since then, Pure has been on a mission to make all-flash data centre a reality and today, this vision is closer than ever to becoming a reality.
