Be too busy to save timeThe efficiency of data center management can be measured by wasted time and money. In a recent survey, 200 data center managers from the US and UK said that using tools such as data center infrastructure Management (DCIM) solutions could make their jobs "easier, faster, and cost-efficient".If applying a DCIM solution can really save time and reduce operational costs, why did the survey find that 43% of data center managers stil
