• A Reference Architecture for NVMe over Fabrics

    March 20, 2018

    Cavium has raised its profile over the past several years as one of the pioneers in developing Arm-based systems-on-a-chip (SoCs) for servers, rolling out multiple generations of its ThunderX chips in hope of pushing Arm’s low-power architecture make gains in a datacenter environment that for years has been dominated by Intel and its x86-based Xeons.

    However, like similar chip makers, Cavium didn’t start with the Arm server chips, but instead built to that point atop a broad array of products for other areas of the datacenter, including adapters, controllers, switches and MIPS-based processors for networking and storage devices. …

  • All Flash No Longer Has To Compete With Disk

    December 9, 2016

    All-flash arrays are still new enough to be somewhat exotic but are – finally – becoming mainstream. As we have been saying for years, there will come a point where enterprises, which have much more complex and unpredictable workloads than hyperscalers and do not need the exabytes of capacity of cloud builders, just throw in the towel with disk drives and move to all flash and be done with it.

    To be sure, disk drives will persist for many years to come, but perhaps not for as long as many as disk drive makers and flash naysayers had expected – …

  • DDN Targets I/O Bottlenecks With Wolfcreek Arrays

    November 23, 2015

    The old adage in the modern datacenter is that compute is free, but data movement is very, very expensive. We would add that data storage is also nearly free, although at the scale that hyperscalers and HPC centers operate, the numbers add up pretty quickly and suddenly you are spending tens to hundreds of millions of dollars to store data.

    Hence, the whirring pace of innovation in storage, where data needs to be moved more quickly and stored less expensively to be of practical use.

    As we have previously explained, DataDirect Networks got its start in 1998 as a storage …
