Flash forward: What's next for flash storage technology
Emerging flash technologies target capacity, reliability and cost, while the line between storage and memory continues to blur. Over the past couple of years, we've seen four major developments in flash storage technology: 3D architectures, which will allow denser NAND chips; memory channel flash, which uses a server's DIMM slot and bus to add solid-state storage; nonvolatile memory express (NVMe), which offers a more efficient way to tap into a server's PCIe bus to wring out more performance; and nonvolatile dual in-line memory module (NVDIMM), which adds a nonvolatile tier to system RAM. All of these techs are available now. This issue of Storage magazine outlines the best use cases and the advantages/disadvantages of each flash storage technology.
Each new version of VMware's vSphere introduces new storage capabilities and features to support virtual servers. This issue explains vSphere's latest storage stuff, including new capacities, new performance controls and other storage-related management features. We'll also look at how storage vendors plan to support the new features.
It doesn't matter what industry you're in, the size of your company or whether your shop is fully virtualized -- the odds are that you struggle to control or keep up capacity growth. With more devices than ever creating data and more uses for that data, many companies are reluctant to deep-six anything. Luckily, there are new and cost-effective ways to cope with all that data without breaking the bank.
