Intel Proclaims New Wave of Optane and 3D NAND SSDs

Immediately Intel is asserting updates to most of their SSD product traces. Their merchandise primarily based on 3D NAND are being up to date to make use of Intel’s 144-layer QLC and TLC NAND. On the Optane facet of the enterprise, now we have detailed specs for the primary product to make use of second-generation 3D XPoint reminiscence, and an up to date Optane Reminiscence caching resolution for shopper PCs. Intel has additionally revealed the code title for his or her third-generation Optane persistent reminiscence modules, which will probably be launching alongside Sapphire Rapids Xeon processors.

  • SSD D7-P5510 – Datacenter NVMe, 144L TLC
  • SSD D5-P5316 – Datacenter NVMe, 144L QLC

  • Optane Persistent Reminiscence 300 Collection: Crow Go – 3D XPoint DIMMs

A few of these merchandise have already began delivery and are formally launching this month, whereas others are merely being introduced at this time and will probably be launching in 2021, with full specs and pricing disclosed nearer to launch.

144L 3D NAND For Datacenter SSDs

The primary two SSD bulletins are updates to Intel’s datacenter SSDs utilizing 3D NAND. The brand new D7-P5510 makes use of 144L 3D TLC NAND and is the successor to the D7-P5500 which makes use of 96L TLC. Because the P5500 was an OEM-only product moderately than broadly distributed by way of the channel, the P5510 may even function the successor to the P4510 for the portion of the shopper base. Intel has not introduced a 144L alternative for the D7-P5600, the higher-overprovisioning counterpart to the P5500.

Utilizing Intel’s 144L QLC NAND is the brand new D5-P5316 SSDs in 15.36 TB and 30.72 TB capacities in both U.2 or E1.L type elements. The E1.L model permits Intel to attain the unique aim of the “Ruler” type issue by enabling 1PB of storage in a 1U server. Because the P5316 is changing the older P4326 (64L QLC and PCIe gen3), it is a way more substantial improve over its predecessor than the TLC-based P5510 is. Except for the introduction of Intel’s third-generation enterprise NVMe SSD controller to their QLC product line, crucial change the P5316 brings is a significant shift in how the Flash Translation Layer works. The P5316 permits a 16x discount in DRAM by altering the SSD’s Flash Translation Layer to work with a granularity of 64kB moderately than 4kB. We have seen a number of different enterprise SSDs make this sort of change, equivalent to Western Digital’s Ultrastar DC SN340, which makes use of a 32kB FTL granularity. The DRAM financial savings of a extra coarse-grained FTL assist make high-capacity SSDs extra reasonably priced, however on the expense of severely harming efficiency and rising write amplification for small block dimension random writes. The final development within the business is to undertake NVMe Zoned Namespaces for such drives, stopping random writes completely moderately than counting on host software program to watch out about issuing small-block IOs. Nevertheless, Intel would not appear to be able to undertake this method but.

Each the TLC-based P5510 and QLC-based P5316 use the identical controller platform as Intel’s different P5000-series SSDs introduced earlier this yr. These drives launched Intel’s third-generation enterprise NVMe SSD controller, their first supporting PCIe 4.0. The brand new 144L drives do not actually push efficiency or function set any additional, however will probably be extra broadly accessible and ought to be cheaper than the 96L drives. The TLC-based P5510 has already been sampled to prospects for qualification and will probably be delivery for income by the tip of this yr. The QLC-based P5316 is sampling and will probably be accessible within the first half of 2021.


SSD 670p: 144L QLC For Shoppers

Shifting on to the buyer SSD enterprise, Intel will probably be introducing the 670p QLC NVMe SSD within the first quarter of 2021. This follows within the footsteps of the 660p and 665p with one other replace to newer 3D QLC NAND, and in addition brings a SSD controller replace to this product line. Nevertheless, it’s nonetheless solely a PCIe gen3 product. Intel will probably be reintroducing the 512GB capability that was lacking from the 665p, however they don’t seem to be but including capacities past 2TB. Detailed efficiency specs and pricing will probably be shared nearer to the 670p’s launch.

Intel is making an adjustment to the dynamically-sized SLC caching habits with the brand new 670p. Whereas the utmost and minimal SLC cache sizes should not altering, Intel has managed to enhance the cache dimension that will probably be accessible for a partially-filled drive: A half-full 670p will nonetheless have virtually the utmost SLC cache dimension accessible, and the minimal cache dimension is not going to be reached till the drive is over 85% full. This most likely will not change something for easy benchmarks that write constantly till the cache runs out and efficiency drops, however it’s going to assist real-world utilization the place writes are available in bursts.

Optane SSD P5800X: Alder Stream Arrives

Intel’s long-awaited second-generation Optane enterprise SSD, codenamed Alder Stream, is lastly delivery because the P5800X. That is the primary product to make use of second-generation 3D XPoint reminiscence, and it additionally options an up to date controller to help PCIe 4.0. The P5800X pushes the bounds of the efficiency accessible from a PCIe 4.0 x4 interface with sequential reads, random reads and random writes all supported at kind of line velocity, and sequential writes solely a bit slower at 6.2 GB/s. And whereas 1.5M IOPS for both random reads or random writes is already very spectacular, the P5800X may even hit 1.8M IOPS on a 70/30 combine—solely potential as a result of PCIe is a full-duplex interface. Intel has additionally made optimizations for single-sector 512-byte random reads, which may hit 4.6M IOPS. (Flash-based SSDs are normally not capable of provide any increased IOPS for 512B reads than 4kB reads, and plenty of even have considerably decrease efficiency for small block IO.)

The primary-generation Optane DC P4800X launched with a 30 DWPD write endurance ranking, later elevated to 60 DWPD. The brand new P5800X additional will increase write endurance to 100 DWPD. Capacities will vary from 400GB to three.2TB.


Optane Reminiscence H20

The shopper/shopper targeted portion of Intel’s Optane product household has shrunk significantly. They’re now not doing Optane M.2 SSDs to be used as major storage or cache drives, and there is been no point out but of an enthusiast-oriented spinoff of the P5800X to exchange the Optane SSD 900P and 905P (although if Intel plans such a product, they’re unlikely to announce it till they’ve delivered a desktop platform supporting PCIe 4.0). The one shopper Optane product Intel has been speaking about these days is the Optane Reminiscence H10 hybrid drive consisting of a QLC NVMe SSD and an Optane SSD on the identical M.2 card. A successor is now on the way in which: the Optane Reminiscence H20 is deliberate for Q2 2021, incorporating updates on the QLC facet that possible mirror the 670p’s updates, and a brand new controller on the Optane half of the drive. The H20 will nonetheless be a PCIe gen3 resolution, so we are going to most likely proceed to see efficiency of the NAND facet constrained by solely getting access to two of the 4 PCIe lanes. Intel can also be bumping up the platform necessities: an Eleventh-generation Core U-series cell processor and 500-series chipset, and Intel RST driver model 18.1 or later. When the H10 launched, Intel had laid the groundwork for help on their desktop platforms, however this effort was dropped when the H10 turned an OEM-only product. The H20 is a mobile-focused OEM-only half from the outset, so the platform compatibility necessities aren’t as a lot of a problem as they might be for a retail SSD.

The Optane Reminiscence H20 will probably be accessible with 512GB or 1TB of QLC NAND flash reminiscence, every paired with 32GB of 3D XPoint reminiscence.


Optane Persistent Reminiscence 300 Collection: Crow Go

Intel’s Optane Persistent Reminiscence merchandise (3D XPoint in a DIMM type issue) are at the moment on the second era 200 sequence Barlow Go supported by Cooper Lake and upcoming Ice Lake Xeon platforms. The 200 sequence Optane Persistent Reminiscence modules nonetheless use first-generation 3D XPoint reminiscence. Intel has now disclosed that the subsequent era on the roadmap is codenamed Crow Go, which is able to possible be branded because the 300 sequence. The Crow Go modules will probably be launched to be used with Intel’s Sapphire Rapids Xeon processors. These are anticipated to make use of DDR5 reminiscence, so Crow Go will probably be a significant replace to the interface for Optane Persistent Reminiscence. Crow Go also needs to convey second-generation 3D XPoint reminiscence to the DIMM type issue, so altogether that is more likely to be a way more vital replace than the comparatively minor enhancements introduced by the 200 sequence.
