Yesterday we saw Samsung introduce their 'NGSFF' form factor during yesterday's keynote. Intel has been at work on a similar standard, this one named EDSFF (Enterprise & Datacenter Storage Form Factor), with the simpler working name as 'Ruler', mainly because it bears a resemblance:
Note that the etching states P4500 Series. P4500 was launched a couple of days ago and is Intel's next generation NVMe PCIe Datacenter SSD. It's available in the typical form factors (U.2, HHHL), but this new Ruler form factor contains the exact same 12 channel controller and flash counts, only arranged differently.
SFF-TA-1002 connector (aka 'Gen-Z'), shown next to an AA battery for scale. This connector spec is electrically rated for speeds up to 4th and 5th generation PCIe, so future proofing was definitely a consideration here. In short, this is a beefed up M.2 style connector that can handle more throughput and also has a few additional pins to support remote power and power-loss-protection (capacitors outside the Ruler), as well as support for activity LEDs, etc.
Here is a slide showing the layout of the Ruler. 36 flash packages can be installed, with the possibility of pushing that figure to 42.
Thermals were a main consideration in the design, and the increased surface area compared to U.2 designs (with stacked PCBs) make for far cooler operation.
Intel's play here is fitting as much flash as possible into a 1U chassis. 1PB in a 1U is definitely a bold claim, but absolutely doable in the near future.
I'll leave you with the quick sniper shot I grabbed of their demo system. I'll be posting more details on the P4500 and P4600 series products later this week (remember, same guts as the Ruler), so stay tuned!
