Mainstream enterprise storage vendors are embracing NVMe. HPE, NetApp, Pure Storage, Dell EMC, Kaminario and Tegile all offer all-NVMe arrays. According to these vendors, the products will soon support storage class memory as well. NVMe protocol access to flash memory SSDs is a big deal. Support for storage class memory may become an even bigger deal.
Solid State Storage Flash Memory
Non-volatile Memory Express (NVMe) has captured the fancy of the enterprise storage world. Implementing NVMe on all-flash arrays or hyper-converged infrastructure appliances carries with it the promise that companies can leverage these solutions to achieve sub-millisecond response times, drive millions of IOPS, and deliver real-time application analytics and transaction processing. But differences persist between what NVMe promises for these solutions and what it can deliver. Here is a practical look at NVMe delivers on these solutions in early 2018.
Early in my IT career, a friend who owns a software company told me he had been informed by a peer that he wasn’t charging enough for his software. This peer advised him to adopt a “flinch-based” approach to pricing. He said my friend should start with a base licensing cost that meets margin requirements, and then keep adding on other costs until the prospective customer flinches. My friend found that approach offensive, and so do I.
The all-flash array market has settled down considerably in the last few years. While there are more all-flash arrays (90+ models) and vendors (20+) than ever before, the ways in which these models can be grouped and classified has also become easier. As DCIG looks forward to releasing a series of Buyer’s Guides covering all-flash arrays in the coming months, it can break these all-flash arrays into five (and soon to be six) general classifications based upon their respective architectures and use cases.
