BeeGFS stayin' alive with Intel OPA tie-up

Because what the world needs now is another HPC filesystem


The HPC-focussed parallel cluster file system, BeeGFS, has received certification to run over Intel's OmniPath Architecture (OFA).

The cert, plus a collaboration with Intel's OPA team, is a step forward for BeeGFS, which was spun out of Fraunhofer in 2014 and made the responsibility of ThinkParQ.

BeeGFS runs on Linux distros with kernels between 2.6.18 and 4.5, and is currently on the package list for Red Hat Enterprise Linux 5-7, Fedora, SUSE Linux Enterprise Server 11/12 (and the OpenSuse equivalents), Debian 7 and 8, and Ubuntu.

In its certification tests, the filesystem was tested on dual-socket Broadwell Xeon systems (E5-2680v4) with OPA interconnect, and achieved more than 8 gigabytes/second write throughput for an IOR single stream benchmark, running at just 2.8 per cent CPU utilisation; and for an IOR benchmark with four file streams on the same setup, throughput was claimed to be better than 12 GB/second at 6.2 per cent CPU utilisation.

This, ThinkParkQ's canned blurb (PDF) claims, would support I/O of up to 120 GB/s in a single rack of 4U storage servers.

BeeGFS supports either IP or Infiniband-plus-VERBS for the communication channel. Its components are a management server, object storage server, metadata server, and a filesystem client, and for storage it can support any Posix-compatible local filesystem.

The BeeGFS client is GPL, while the server components are free and subject to the Fraunhofer EULA. ®

  • Cheers ransomware hits VMware ESXi systems
    Now we can say extortionware has jumped the shark

    Another ransomware strain is targeting VMware ESXi servers, which have been the focus of extortionists and other miscreants in recent months.

    ESXi, a bare-metal hypervisor used by a broad range of organizations throughout the world, has become the target of such ransomware families as LockBit, Hive, and RansomEXX. The ubiquitous use of the technology, and the size of some companies that use it has made it an efficient way for crooks to infect large numbers of virtualized systems and connected devices and equipment, according to researchers with Trend Micro.

    "ESXi is widely used in enterprise settings for server virtualization," Trend Micro noted in a write-up this week. "It is therefore a popular target for ransomware attacks … Compromising ESXi servers has been a scheme used by some notorious cybercriminal groups because it is a means to swiftly spread the ransomware to many devices."

  • Twitter founder Dorsey beats hasty retweet from the board
    We'll see you around the Block

    Twitter has officially entered the post-Dorsey age: its founder and two-time CEO's board term expired Wednesday, marking the first time the social media company hasn't had him around in some capacity.

    Jack Dorsey announced his resignation as Twitter chief exec in November 2021, and passed the baton to Parag Agrawal while remaining on the board. Now that board term has ended, and Dorsey has stepped down as expected. Agrawal has taken Dorsey's board seat; Salesforce co-CEO Bret Taylor has assumed the role of Twitter's board chair. 

    In his resignation announcement, Dorsey – who co-founded and is CEO of Block (formerly Square) – said having founders leading the companies they created can be severely limiting for an organization and can serve as a single point of failure. "I believe it's critical a company can stand on its own, free of its founder's influence or direction," Dorsey said. He didn't respond to a request for further comment today.

  • Snowflake stock drops as some top customers cut usage
    You might say its valuation is melting away

    IPO darling Snowflake's share price took a beating in an already bearish market for tech stocks after filing weaker than expected financial guidance amid a slowdown in orders from some of its largest customers.

    For its first quarter of fiscal 2023, ended April 30, Snowflake's revenue grew 85 percent year-on-year to $422.4 million. The company made an operating loss of $188.8 million, albeit down from $205.6 million a year ago.

    Although surpassing revenue expectations, the cloud-based data warehousing business saw its valuation tumble 16 percent in extended trading on Wednesday. Its stock price dived from $133 apiece to $117 in after-hours trading, and today is cruising back at $127. That stumble arrived amid a general tech stock sell-off some observers said was overdue.
