Supermicro's super Nexenta HGST superduper AFA

NexentaStor flies with flash wings from HGST and fuselage from Supermicro


NexentaStor has come round the all-flash array block a second time with a Supermicro flash server box slotting underneath the SanDisk-powered 512GB InfiniFlash box.

The product is based on Supermicro's 2U Ultra SuperServer hardware, fitted with HGST Ultrastar SSDs in 800GB or 1.6TB capacities.

The Ultra SuperServer – will the next one be called the Extreme Ultra SuperServer or the SuperExtreme UltraServer? – has dual Intel E5-2643 v3 (3.4GHz, 6-core) processors, 256GB of RAM, 12Gbt/s SAS HBAs and is locked and loaded with NexentaStor v4.0 software.

There are four storage JBOD enclosures fitted with hot-swap SSDS:

  • 19TB with 24 x 800GB; 2U we think
  • 38TB with 24 x 1.6TB
  • 76TB with 48 x 1.6TB; 4U we think
  • 115TB with 72 x 1.6TB

These are raw capacities and there could be higher effective capacities depending on the data reduction effectiveness. They look like straightforward systems and affordable ones, with data access latency at the sub-millisecond level. Compared to the equivalent boxes filled with disk drives, these are sprinters versus marathon runners.

We're entering the era of the commoditization of all-flash arrays and the pricing underscores that. As does the OEM'ing of NexentaStor by SanDisk and Supermicro for their all-flash arrays.

We're told to expect up to 200,000 (32K) IOPS and 6GB/sec throughput. List prices range from $2/GB raw to $3.5/GB raw. So a 19TB system at $3.5/GB would be $66,500. Dell has cheaper boxes on a $/GB basis. ®

    Transitioning just half of all datacenters to sustainable operating models could cut global energy costs by $7 billion, Supermicro CEO Charles Liang claims.

    Building greener datacenters was a central theme of the company’s nearly hour-long Computex keynote earlier this month, where Liang touted Supermicro’s efforts to reduce carbon emissions through modular server design and encouraging liquid cooling.

    “It’s our responsibility to reduce the environmental impact of technology by using less power, reducing carbon footprint and e-waste,” he said.

    The San Diego Supercomputer Center (SDSC) says it's ready to run test workloads on its experimental Voyager AI system, which looks to be the first-ever Intel Habana-based supercomputer.

    The supercomputer was built in collaboration with Intel's Habana Labs and Supermicro as part of a five-year $11.25 million grant from America's National Science Foundation. And while powerful, Voyager isn't trying to win any benchmark records — it's not supposed to.

    Voyager is intended to be a proving ground for AI/ML computing research and development on specialized hardware — in this case, Habana's Goya and Gaudi processors — Voyager Principal Investigator Amit Majumdar told The Register.

  • Supermicro's 'universal GPU' system welcomes all elements
    Biz claims ultra-composable server platform is future-proof

    Supermicro’s new "Universal GPU" servers, announced on Monday, is as equal-opportunity as silicon tech can get – it does not discriminate on CPUs, GPUs, storage, and networking technologies.

    The boxen can be constructed in a number of ways to include processors from Intel and AMD, and graphics accelerators from AMD and Nvidia. It can be further customized to include proprietary technologies that include Nvidia's NVLink or AMD's Infinity Fabric interconnects to link up multiple GPUs.

    The datacenter-class systems, which will come in 4U or 5U sizes, have a “modular” architecture based on standards established by the Open Compute Project, such as the OCP Accelerator Modules (OAM). The modular approach allows for more economical CPU and GPU upgrades without replacing entire systems, Supermicro said.
