The main advantages of NVMe flash drives are the low latency and high performance per drive. Those advantages are also the biggest challenges: each drive can generate hundreds of thousands of IOPS but if those drives are installed in a traditional storage array, much of the potential raw performance is lost due to limitations of the controllers. The customer is forced to use more drives and more controllers to obtain the performance they need. This problem is compounded by flash capacity, which continues to increase in density. The result is the customer ends up buying more drives than they should to meet performance requirements and ends up with terabytes of wasted capacity.
In our latest Lightboard Video, Storage Switzerland and Excelero discuss how to reach the full performance potential of NVMe drives while still maintaining the capacity efficiencies of a shared storage environment.
