#208 – NVIDIA GPUDirect Storage – More Than a Good Marketing Message?

Chris EvansGarbage Collection, NVIDIA, Storage Unpacked Podcast

In this week’s podcast, Chris and Martin look at NVIDIA’s GPUDirect Storage (GDS), a technology for moving data directly from persistent storage to GPUs, bypassing the CPU. The aim of the technology is to provide greater throughput to keep GPUs active, and looking at some of the thoughts from our podcast with Liqid (#204), it’s clear that this feature is needed. However, with such quick adoption by many storage vendors, is the announcement of GDS more of a marketing exercise? We dig into the details and what the announcement of GDS could mean for the future enterprise.

On a side note, there was indeed a remake of Magnum P.I. in 2018, following on from the original series in 1980. The original was a classic; we’re not sure about the remake.
