Worth Reading: NVMe for Data Centers

The Non-Volatile Memory Express (NVMe) specification defines a new method to access solid-state drives (SSDs) over a PCIe bus, and it’s forecasted to grow exponentially over the next few years thanks to its performance advantages and lower latencies compared with legacy protocols (such as SATA). NVMe-enabled storage infrastructures are not only seeing wide deployment, but they’re now entering other data center areas that were once typically reserved for legacy HDDs and SSDs. NVMe has become an agent for next-generation data centers. To understand this evolution, it’s important to review the history and examine some of the new application workloads that are being transformed by this protocol. —Anand Jayapalan @ The Data Center Journal
