RoCE or roll in the general, er, Vcinity: Thousand mile-plus RDMA makes remote editing seem local

San Jose peeps tout distance-killing file data access

California networking startup Vcinity said this week that its networking products shunted a petabyte of data 7,000km in under 24 hours, providing access to remote files thousands of kilometres away with a 250ms round trip time.

How does Vcinity explain its hardware and software driving a link so fast? The firm said it used a patented Global Fabric Extension technology with Ultimate X (ULT X) software and RDMA (Remote Direct Memory Access). It claimed it can use up to 95 per cent of a link's available bandwidth but did not explain how.

ULT X presents itself outwardly as a NAS (NFS v3/4 and SMB v3) or transitional storage tier, and has a global namespace and network-mapped drive volumes. Vcinity said it is compatible with various storage systems for file storage.

The product set includes:

  • ULT X software in on-premises Linux server or as software-only to run in the cloud
  • RAD X kit:
    • X-1010e (1/10Gbit/s)
    • 1040 (1/10/40 Gbit/s and FDR InfiniBand)
    • 1100 (1/10/40/100 RoCE and FDR/EDR InfiniBand)
  • Command X web-based GUI management facility included with ULT X
  • Access X file management and sync tool to copy and move folders
  • Sync X is a web-based file synchronisation and backup tool

The RAD X cards need ULT X software on their host server and use RoCE (RDMA over converged Ethernet) or InfiniBand over any layer 2/2.5/3 network with traffic engineering and congestion management of flows across the network.

This kit is only available from Vcinity's channel partners.

Noboru Aoki at Core Microsystems said of the tech: "For our Media and Entertainment clients, the Vcinity Ultimate X solution allows video producers to edit remote content across any distance as if it were local to their desktop.

"Editors are no longer required to replicate content at multiple locations, avoiding redundant copies of the content, leading to dramatic storage efficiencies as well as improved control and security." ®

  • Tesla driver charged with vehicular manslaughter after deadly Autopilot crash

    Prosecution seems to be first of its kind in America

    A Tesla driver has seemingly become the first person in the US to be charged with vehicular manslaughter for a deadly crash in which the vehicle's Autopilot mode was engaged.

    According to the cops, the driver exited a highway in his Tesla Model S, ran a red light, and smashed into a Honda Civic at an intersection in Gardena, Los Angeles County, in late 2019. A man and woman in the second car were killed. The Tesla driver and a passenger survived and were taken to hospital.

    Prosecutors in California charged Kevin George Aziz Riad, 27, in October last year though details of the case are only just emerging, according to AP on Tuesday. Riad, a limousine service driver, is facing two counts of vehicular manslaughter, and is free on bail after pleading not guilty.

  • AMD returns to smartphone graphics with new Samsung chip for your pocket computer

    We're back in black

    AMD's GPU technology is returning to mobile handsets with Samsung's Exynos 2200 system-on-chip, which was announced on Tuesday.

    The Exynos 2200 processor, fabricated using a 4nm process, has Armv9 CPU cores and the oddly named Xclipse GPU, which is an adaptation of AMD's RDNA 2 mainstream GPU architecture.

    AMD was in the handheld GPU market until 2009, when it sold the Imageon GPU and handheld business for $65m to Qualcomm, which turned the tech into the Adreno GPU for its Snapdragon family. AMD's Imageon processors were used in devices from Motorola, Panasonic, Palm and others making Windows Mobile handsets.

    Billionaire tech investor and ex-Facebook senior executive Chamath Palihapitiya was publicly blasted after he said nobody really cares about the reported human rights abuse of Uyghur Muslims in China.

    The blunt comments were made during the latest episode of All-In, a podcast in which Palihapitiya chats to investors and entrepreneurs Jason Calacanis, David Sacks, and David Friedberg about technology.

    The group were debating the Biden administration’s response to what's said to be China's crackdown of Uyghur Muslims when Palihapitiya interrupted and said: “Nobody cares about what’s happening to the Uyghurs, okay? ... I’m telling you a very hard ugly truth, okay? Of all the things that I care about … yes, it is below my line.”
