#126 – Software-Defined Storage in Review with Hal Woods

Chris EvansGuest Speakers, Software-Defined Storage

This week, Chris and Martin talk to Datera CTO, Hal Woods about the state of the software-defined storage (SDS) market. SDS emerged around ten years ago as a solution to overcome the expense of buying storage appliances. With cheap hardware, IT organisations could simply buy software or use one of many open-source solutions.

Has SDS been successful and how has it evolved? Early modes of deployment simply ran existing storage software on commodity hardware. As the category developed, software defined storage has been built specifically to address a new set of requirements. These are typically based around offering more dynamic and flexible ways to implement persistent storage.

How has public cloud changed the perception of SDS? Clearly, IT teams are much more comfortable with storage as a service and solutions that deliver to standard metrics like latency, throughput and performance. Cloud challenges businesses to look at their TCO and baseline costs to understand the right solution for their needs.
