in SC24 The supercomputing conference was held in November in Atlanta, Happy birthday to you (The actor who played the Mountain in “Game of Thrones”), dead Custom hardware weighs 453 kilograms (1,000 pounds) of solid state drive (SSD). The data stored in the drives totaled just over 280 petabytes.
“Without a doubt, this is the most human-raised data in history,” he says. Andy HigginbothamSenior Business Development Manager at Phison Electronics. High-performance data platform vdura He organized the standard lift in collaboration with Phison.
Behind this hype, there is a real trend: feeding insatiable AI Data appetiteMemory drives are growing, with no end in sight. Fuson recently Announce The largest SSD memory drive to date, storing 128TB of data, hundreds of them piled up in Björnsson’s Barbell. Within a few weeks, soldigm Announce 123 tennis drive. Samsung and Western digital It also recently began carrying similar products.
The shift towards more AI workloads in data centers has largely led to this Hungry for power Chips, mostly Graphics processing units. As overall data center energy use rises, people are looking for ways to use less energy whenever possible. At the same time, Great language models And others Artificial intelligence models Requires increasing amounts of memory.
“You can see where storage requirements are going,” he says. Roger CoryellSenior Director of Artificial Intelligence and Leadership Marketing at Solidigm. “You’re looking at a large language model that just a couple of years ago, you had half a petabyte per rack or less. And now there are large language models that are between three and three and a half bytes per rack. Storage efficiency to enable continued scaling of the AI infrastructure is really important.”
Crucially, this new crop of hard drives takes up the same space in the computing rackAnd the power budget is roughly like 32TB and 64TB – although a little longer – than can be swapped around in data centers to get easy wins.
3 Ways to Boost SSD Capacity
“There are three types of vectors you can innovate on to increase the capacity of each SSD,” Correll says. “One is the bits per cell, and then two is how many cells you can pack into one layer, and how many layers you can stack of those memory cells.”
The number of bits per cell is literally the number of different values that can be stored in one nand flash Floating submarine Transistor. These transistors are packed onto a layer with ever-increasing density. Adding more layers makes the device taller, but, Corell says, height is not a limiting factor in data centers today, so there is room for expansion.
Soldigm was already making 4-bit-per-cell devices, so they innovated by packing more cells per layer to go from 60 TB A model of its 122TB device, mainly using the smallest NAND technology available and reducing the size of non-NAND components. Phison moved from 3-bit to 4-bit NAND cells, and improved along all three vectors to go from 32TB to its 128TB drive.
Going to a higher number of bits per cell makes write times somewhat slower, but that’s still a win in a lot of applications, he says. Allen MalentanoSenior Director of Technical Marketing at Phison.
Maintaining the same power draw as smaller devices is a fine balancing act. “Drive developers will always have to do to figure out, OK, if we configure it this particular way, maybe we can get some high performance, but if we do, it’s going to take more power in order to do it this right,” Malentano says. “So there’s basically a tuning process that goes on for any given amplitude.”
Demand for high-capacity memory drives is not slowing down. “It’s never going to stop. There’s always going to be more demand for larger SSDs,” Higginbotham says. Soldigm’s Corell predicts there will be Petabyte SSDs on the market before the decade is out.
