DapuStor and Memblaze Goal International Enlargement with State-of-the-Artwork Enterprise SSDs

The expansion within the enterprise SSD (eSSD) market has outpaced that of the consumer SSD market over the previous few years. The necessities of AI servers for each coaching and inference has been the main impetus on this entrance. Along with the standard distributors like Samsung, Solidigm, Micron, Kioxia, and Western Digital serving the cloud service suppliers (CSPs) and the likes of Fb, a lot of firms have been at work inside China to service the burgeoning eSSD market inside.

In our protection of the Microchip Flashtec 5016, we had famous Longsys’s use of Microchip’s SSD controllers to arrange and market enterprise SSDs beneath the FORESEE model. Lengthy earlier than that, two firms – DapuStor and Memblaze – began releasing eSSDs particularly specializing in the Chinese language market.

There are two drivers for the present development spurt within the eSSD market. On the efficiency facet, utilization of eTLC behind a Gen 5 controller is permitting distributors to promote important advantages over the Gen 4 drives within the earlier technology. On the similar time, a capability play is going on the place there’s a race to cram as a lot NAND as attainable right into a single U.2 / EDSFF enclosure. QLC is getting used for this goal, and we noticed a lot of such 128 TB-class eSSDs on show at FMS 2024.

DapuStor and Memblaze have each been counting on SSD controllers from Marvell for his or her flagship drives. Their newest product iterations for the Gen 5 period use the Marvell Bravera SC5 controller. Much like the Flashtec controllers, these are usually not meant to be turnkey options. Slightly, the SSD vendor has appreciable flexibility in implementing particular options for his or her desired goal market.

At FMS 2024, each DapuStor and Memblaze have been displaying their newest options for the Gen 5 market. Memblaze was celebrating the sale of 150K+ items of their flagship Gen 5 resolution – the PBlaze7 7940 incorporating Micron’s 232L 3D eTLC with Marvell’s Bravera SC5 controller. This SSD (out there in capacities as much as 30.72 TB) boasts of 14 GBps reads / 10 GBps writes together with random learn / write efficiency of two.8 M / 720K – all with a typical energy consumption south of 16 W. Moreover, the assist for a few of NVMe options similar to software-enabled flash (SEF) and zoned identify house (ZNS) had helped Memblaze and Marvell to receive a ‘Better of Present’ award beneath the ‘Most Modern Buyer Implementation’ class.

DapuStor had their present lineup on show (together with the Haishen H5000 collection with the identical Bravera SC5 controller). The corporate incorporates YMTC NAND into the drives offered within the Chinese language market. Nevertheless, for different areas, BiCS flash is getting used. Moreover, the corporate had an unannounced proof-of-concept 61.44 TB QLC SSD on show. Regardless of the label carrying the Haishen5 collection tag (its present members all use eTLC NAND), this pattern comes with QLC flash.

DapuStor has already invested sources into implementing the versatile information placement (FDP) NVMe function into the firmware of this QLC SSD. The corporate additionally had an fascinating presentation session coping with utilization of CXL memory expansion to store the FTL for high-capacity enterprise SSDs – although that is one thing for the long run and never associated to any present product out there.

Having established themselves inside the Chinese language market, each DapuStor and Memblaze need to broaden in different markets. Having merchandise with main efficiency numbers and options within the eSSD development section will stand them in good stead on this endeavor.
