Intel's new Ruler form factor allows up to 1PB of NVMe in 1U, along with a new 2.5" 3.8TB SATA SSD and Dual Port SSDs for Data Centers

    First, NAND based SSDs arrived in SATA, SAS, and PCIe form factors, almost a decade ago. In 2015, NVMe became widely available, in various shapes and sizes, including U.2 (looks like a thick metal 2.5" laptop drive), and HHHL (Half Height Half Length) PCIe cards, aka AIC (Add In Card)s. With the recent release of Intel xeon Scalable Processors (Purley), we have new servers that include NVMe cards in those hot-swap 2.5" drive bays, such as the 2U Dell EMC PowerEdge R740xd, for example.

    But what if you're working within the constraints of a 1U server design? In advance of the Intel Flash Memory Summit running from August 8-10 in Santa Clara CA last week, a bunch of announcements were already made on August 7, including:

    • “Ruler” form factor for Intel® SSDs, an all-new solid state drive form factor enabling up to 1PB of storage in a 1U server rack in the future.
    • The world’s most advanced dual port portfolio: Intel® Optane™ technology dual port SSDs and Intel® 3D NAND dual port SSDs for mission-critical applications.
    • An updated SATA family of SSDs for data center, targeted at HDD replacement.

    ‘Ruler’ Form Factor for Intel SSDs

    The new “ruler” form factor, so-called for its long, skinny shape, shifts storage from the legacy 2.5-inch and 3.5-inch form factors that follow traditional hard disk drives, and the add-in card form factor, which takes advantage of PCIe card slots, and delivers on the promise of non-volatile storage technologies to eliminate constraints on shape and size. The new form factor delivers the most storage capacity for a server, with the lowest required cooling and power needs. The next-generation “ruler” form factor SSDs using Intel® 3D NAND technology will enable up to 1PB in a 1U server – enough storage for 300,000 HD movies, or about 70 years of nonstop entertainment. Both Intel Optane SSDs and Intel® 3D NAND SSDs in the “ruler” form factor will come to market in the near future.

    Dual Port SSDs

    Dual port Intel Optane SSDs and Intel® 3D NAND SSDs offer critical redundancy and failover, protecting against multiple paths to failure for mission-critical and high-availability applications. Dual port SSDs replace SAS SSDs and HDDs and, with new storage technologies, deliver more IOPS, more bandwidth and lower latency than SAS SSDs. Dual port Intel® SSD DC D4500, D4502 and D4600 Series will be available starting in 2017’s third quarter.

    SATA SSDs for Data Centers

    The Intel® SSD DC S4500 and S4600 Series combine a new Intel-developed SATA controller, innovative SATA firmware and the industry’s highest density 32-layer 3D NAND. These storage-inspired SSDs preserve legacy infrastructure, ensuring a simple transition from hard disk drives to SSDs, while enabling data centers to reduce storage cost, increase server efficiency and minimize service disruptions. The new members of the second-generation Intel®3D NAND SSD family are available now.

    What about home labs?

    It would seem that M.2 NVMe "gumstick" has the best shot at sticking around for a while, tucking into a little slot right there on compact Intel NUC and Xeon D motherboards, along with even smaller form-factor devices like laptops. I would hope to see standardization on ejectable PCIe media, but I won't be holding my breath, with server vendors intent on a variety of proprietary drive carrier styles

    If a consumer version of the 2.5" DC S4600 3.8TB arrives, and if prices drop low enough, that would be an appealing alternative to the rather common 4TB to 10TB spinning 3.5" drives that have fallen so far in price lately. So far, the only S4600 Series that has surfaced on Amazon is the 960GB, listing a "Date First Available" of August 11, 2017. The 1.9TB S4500 is also on Amazon now.

    Closing thoughts

    Page 6 of the presentation deck below couldn't make it more clear that Intel wishes for the Ruler to conquer the U.2 form-factor. Such a victory would remove those U.2 drive carriers from server designs, a loss I figure OEMs would mourn more than server owners.
