In this episode, Chris talks to Shawn Rosemarin (VP, R&D, Customer Engineering) from Pure Storage about the evolution towards 300TB direct flash modules, the custom-designed SSDs used in FlashArray and FlashBlade. Pure Storage has stated an intention to deliver 300TB modules by 2026. With only three years to achieve that goal, how will the company move from today’s 52TB maximum capacity to 6x the amount of storage in a similar footprint?
There are two key technologies at play here. Firstly, Pure Storage designs and manufactures custom SSDs (DFMs) rather than use commodity devices. This approach offers much greater control over the operation of NAND and other aspects such as DRAM usage and power draw. Second is the use of Purity, the Flash platform operating system, which directly controls the placement of data across NAND.
As DFM flash capacities continue to grow over the next three years, the difference between future HDDs and commodity SSDs will widen. Pure Storage hopes the ability to drastically increase capacity in the same footprint will offer customers a way to cope with environmental costs, the cost of data centre space and meet the increasing storage demands of technologies such as AI.
