There’s by no means a uninteresting second within the enterprise SSD market. Among the many newest developments are three new merchandise from Samsung, Micron and Kioxia. Listed here are the highlights.
Samsung’s new computational storage drive
Samsung unveiled a second era of its SmartSSD, an SSD with a Xilinx FPGA and a few reminiscence for doing computational storage. Computational storage is the method of processing knowledge the place it lies quite than shifting it across the community. It’s a brand new idea and solely attainable with SSDs; there’s no method this could possibly be finished with a mechanical laborious drive.
Samsung launched the SmartSSD in 2020. The primary era featured a Xilinx Versal processor. The brand new model provides software program and mental property (IP) developed by clients, together with in-built Arm cores. Samsung claims processing time for scan-heavy database queries might be slashed by over 50%, vitality consumption by as much as 70%, and CPU utilization by as much as 97% versus standard knowledge heart solid-state drives.
Samsung has not stated when its second era SmartSSD will ship.
Micron smashes the capability barrier
A number of firms are working to interrupt the 200-layer NAND barrier, however Micron is first with its 232-layer NAND chips.
3D stacking is sort of a tower constructing. The reminiscence cells are stacked on high of one another in layers with a pass-through know-how for communications, similar to an elevator. The result’s a lot quicker communication between cells than in the event that they had been unfold out in a 2D sample. To place it one other method, think about the Empire State Constructing with a one-floor design.
Along with the density positive aspects, the 232-layer NAND gives 2.4GB/sec IO pace, which is 50% greater than Micron’s present 176-layer product; 100% extra write bandwidth and as much as 77% larger learn bandwidth than 176-layer chip; and a bundle that is 28% smaller than earlier Micron NAND chip generations. Learn/write endurance has not been disclosed. (Associated: Micron ships excessive density SATA-based SSDs for knowledge facilities)
Kioxia ships PCIe 5-based drives
Kioxia (previously Toshiba) is delivery a CM7 enterprise SSD with the PCIe 5 bus, double the pace of the earlier CM6 drive that makes use of the slower PCIe 4 bus.
The PCIe 5 bus runs at a 4GB/sec/lane bandwidth, twice the pace of the PCIe 4 drive. However you want a brand new CPU to make use of it. PCIe 5 is on the market in Intel’s coming Sapphire Rapids Xeon server processor and AMD’s forthcoming Genoa-era processor.
The CM7 is available in 2.5-inch kind issue, which is commonplace for 2U storage arrays and EDSFF E3.S kind components. That’s the lengthy, skinny kind generally known as the “ruler” kind issue due to its resemblance to a ruler.
It’s constructed from 112-layer BiCS gen 5 3D NAND in TLC (3bits/cell) format, which appears a bit behind the instances with what Micron is doing, however the CM6 used 96-layer flash. The CM7 gives drives in 1.6TB, 3.2TB, 6.4TB and 12.8TB capability.
Kioxia has given the CM7 enterprise options resembling twin ports for top availability purposes, energy loss safety, CG-Opal SED help complying with FIPS-140-3 (government-approved encryption), and Single Root I/O Virtualization (SRIOV).
