E8 Storage Optanes top slot in SPEC file server benchmark

Fastest software builds – if you go by benchmarks

NVMe-over-Fabrics storage array supplier E8 has reclaimed the SPEC SFS 2014 file storage benchmark title from WekaIO.

This benchmark measures file server throughput and response time.

In its second SPEC SFS 2014 benchmark run, E8 equalled WekaIO's 1200 software builds but completed the run with an 0.57ms overall response time, almost half WekaIO's 1.02ms.

The E8 system used Intel Optane (3D XPoint) drives, demonstrating their superior speed compared to flash SSDs.

The configuration used a dual-controller storage appliance with 24 Intel Optane D4800X 750GB dual-port NVMe SSDs, 2 x Intel Xeon 2.0GHz 14-core CPU, and 128GB RAM per controller. 2 x Mellanox ConnectX-4 EN network interface cards are installed per controller.

WekaIO's system was larger, employing 4 x Supermicro Big Twin (4 x 2-CPU nodes in 2U chassis, 4 x NVMe SSDs/node). WekaIO Matrix 3.1 software, 64 x 1.2TB Micron 9100 NVMe SSDs, 11 client nodes, and a Mellanox 100GbitE MSN 2700 switch.

Zivan Ori, co-founder and CEO of E8 Storage, as you'd expect, raved about its hardware, claiming: "E8 Storage's architecture is designed for NVMe... allowing us to deliver... the lowest possible latency at a much lower TCO than many other cache memory solutions."

There are nine SPEC SFS 2914 results and IBM's Spectrum Scale parallel file system features in four of them:

  Builds Overall Response Time (ms) Date
E8 Optane Spectrum Scale 1200 0.57 Aug 2018
WekaIO 1200 1.02 Mar 2018
Huawei OceanStor 1000 0.59 May 2018
E8 SSD Spectrum Scale 600 0.69 Jan 2018
NetApp FAS 8200 520 1.04 Sep 2017
WekaIO 500 3.06 Jul 2017
Cisco Spectrum Scale 240 1.32 Sep 2017
Oracle ZFS 240 1.71 Sep 2016
IBM ESS Spectrum Scale 160 1.21 Apr 2016

Like E8, WekaIO has had two SPEC SFS 2014 benchmark runs, and may well think it could beat E8 again if it, too, used Optane drives. ®

  • SEC probes Musk for not properly disclosing Twitter stake
    Meanwhile, social network's board rejects resignation of one its directors

    America's financial watchdog is investigating whether Elon Musk adequately disclosed his purchase of Twitter shares last month, just as his bid to take over the social media company hangs in the balance. 

    A letter [PDF] from the SEC addressed to the tech billionaire said he "[did] not appear" to have filed the proper form detailing his 9.2 percent stake in Twitter "required 10 days from the date of acquisition," and asked him to provide more information. Musk's shares made him one of Twitter's largest shareholders. The letter is dated April 4, and was shared this week by the regulator.

    Musk quickly moved to try and buy the whole company outright in a deal initially worth over $44 billion. Musk sold a chunk of his shares in Tesla worth $8.4 billion and bagged another $7.14 billion from investors to help finance the $21 billion he promised to put forward for the deal. The remaining $25.5 billion bill was secured via debt financing by Morgan Stanley, Bank of America, Barclays, and others. But the takeover is not going smoothly.

    Cloud security company Lacework has laid off 20 percent of its employees, just months after two record-breaking funding rounds pushed its valuation to $8.3 billion.

    A spokesperson wouldn't confirm the total number of employees affected, though told The Register that the "widely speculated number on Twitter is a significant overestimate."

    The company, as of March, counted more than 1,000 employees, which would push the jobs lost above 200. And the widely reported number on Twitter is about 300 employees. The biz, based in Silicon Valley, was founded in 2015.

    Entire swaths of gear relies on vulnerability-laden Open Automation Software (OAS)

    A researcher at Cisco's Talos threat intelligence team found eight vulnerabilities in the Open Automation Software (OAS) platform that, if exploited, could enable a bad actor to access a device and run code on a targeted system.

    The OAS platform is widely used by a range of industrial enterprises, essentially facilitating the transfer of data within an IT environment between hardware and software and playing a central role in organizations' industrial Internet of Things (IIoT) efforts. It touches a range of devices, including PLCs and OPCs and IoT devices, as well as custom applications and APIs, databases and edge systems.

    Companies like Volvo, General Dynamics, JBT Aerotech and wind-turbine maker AES are among the users of the OAS platform.
